The autumn and winter broadcast of our province will promote greatly expanding rapeseed Work task is incorporated into the assessment of the strategic performance of rural revitalization

Rural New News (Reporter Peng Cuinan, Correspondent Jiang Bo, Hutan) Recently, the notice of our province has issued a notice to clearly incorporate rapeseed autumn and winter production work into government inspections and incentives, grain safety responsibility system assessment, and the scope of the strategic performance assessment of rural revitalization. It is required to vigorously develop the extension of rapeseed rapeseed in winter, and decompose tasks and measures to counties to villages and households. Agricultural rural areas, development and reform, finance, statistics, food and other departments at all levels must establish a working mechanism, adhere to the common management, and in order "Hubei contributions" to ensure food safety and important agricultural products.

The notice requires that the potential of expanding the expansion and expansion in various places, implement the work requirements of "a variety of one acre for one acre", develop winter idle fields in counties and cities such as Jianghan Plain, southeast Hubei, and north of E -Central E -Central Hubei, and focus on promoting the "rice -oil" planting model Expansion of rapeseed; in the hilly counties and cities in the mountainous areas such as northwestern Hubei and southeast Hubei, it focuses on promoting "corn (soybeans) -rapeseed" planting model to expand rapeseed; Plant rapeseed.

The notice is clear that various work measures must be comprehensively compromised. Increase publicity work and mobilize the enthusiasm of farmers to expand rapeseed. The funds of rapeseed projects should be focused on planted, unified fertilizer, and unified machine broadcasting links. Vigorously support new operating entities such as cooperatives and family farms, and vigorously develop rapeseed rapeseed through the form of land circulation, hosting, and farming services. Give full play to the guidance of winter rapedick reward funds, and drive the improvement of rapeseed production and improvement of the entire region. Comprehensively compact the construction of the rapeseed industry chain, strengthen 40%of the reward funds for oil -producing counties for the implementation of the unified supply of rapeseed supply and technical demonstration policies, create a high -quality raw material supply base, and drive farmers and plant subjects to share more industrial chain interests. Based on disaster anti -autumn broadcasting, comprehensively compact the management measures of rapeseed fields, scientifically formulate technical guidance of rapeseed autumn and winter broadcasting, and guide rapeseed autumn and winter broadcasting.

Hubei releases rapeseed autumn and winter production technical guidance opinions

In order to effectively strengthen the work of rapeseed autumn and winter in 2022, successfully complete the tasks of rapeseed expansion, and efficiently promote the beperture wheel work and green high -quality high -quality production demonstration projects, based on the anti -disaster anti -autumn broadcast, and promote the expansion of rapeseed surface to improve quality and efficiency. Release rapeseed autumn and winter production technical guidance.

Preferential selection of good varieties. Use high -quality high -quality and high -quality rapeseed varieties of high -yielding high -yield, stain resistance, and delayed resistance. The varieties of root anti -rooting disease are used in risk areas. Vigorously promote high -oil acid rapeseed varieties in Jingmen City. Actively demonstrate seed treatment technology. Before sowing, you can use New America Star and Rickamine, etc., to promote the rapid development of rapeseed and effectively prevent the seedlings of the seedlings.

Strengthen water management. Do a good job of water management during the broadcasting period so that you can make it as early as possible and broadcast the whole seedlings as soon as possible. In the case of drought, the horse running water was performed once 3-5 days before the rice harvest. After the rice was harvested, the rice was planted. After sowing, it is irrigated by ditch irrigation and seepage compartment to ensure that the compartment surface is wet for more than 3 days. The soil humidity is too large and drainage in advance, so that the field humidity is moderate when harvesting the rice, and the field humidity is too large in the field to harvest rice. If the plowing water of the rice field machine is severe, you can drain the water with a rotary plowing machine first. When there is no water for the water, the bottom fertilizer can be used to fly rapeseed with the drone. Cover the seeds and cover the fat. Open the huggly, lumbar grooves, and enclosure, the width of the van is about 2m, the depth of the parts is 25cm, the width is about 25cm, the waist ditch depth is 30cm, the width is about 30cm, the enclosure depth is 35cm, and the width is about 35cm. The irrigation is smooth. The plowing fields should not irrigate water before sowing, especially the stubble fields will increase the difficulty of the whole land, reduce the quality of the whole land, and delay the optimal broadcast period.

Promote reasonable secret. Sowing in mid-October, the amount of seeds used in the mechanical jointly sowing per mu was 200-250 grams, and the amount of planting per acre of artificial sowing and drone was sowed by 300-400 grams. In case of arid and delay in the broadcast period, the amount of use can be increased accordingly. Seeds that are treated with new American stars can be appropriately reduced. The broadcasting period is generally no later than October 31, and the amount of use per mu is not more than 500 grams, and the density of seedling is about 50,000.

Promote mechanical sowing. In accordance with the principle of early broadcasting, early hair, and fast -growing cultivation of rapeseed, as early as possible during the period of the broadcast period. Promote mechanical sowing methods such as combined machine broadcasting and spinning and flying sowing (artificial sowing), free plowing and flying broadcasts.

The combined machine broadcast (fertilizer and the same broadcast) is suitable for soil sandblasting, smooth drainage, and easy controlling fields. Select 2BF-10 (12, 14) fertilizer and broadcasting machines that can be realized, and complete the processes of rotation, stubble, ditch, ridge, fertilization, suppression, sowing, soil covering, and closure. High -efficiency. In order to increase the planting density to more than 30,000, late broadcast fields can be provided with width (30-35cm) narrow (15-20cm).

The spinning and flying sowing (artificial sowing) is suitable for field blocks with early stubble and relatively sticky soil. First rotate the stubble, weed, fertilize, and then sow with drones or sowing artificially. After sowing, the ditch was opened with a trench machine.

The exemption and flying broadcast is mainly suitable for late rice-oil tanker mode. In the later period, the rice fields are appropriately left (about 30%of the soil water content), and it is advisable to keep the rice harvesting machine lower the field. The combined harvester with straw crushing and throwing device can be harvested rice, which can leave 40-50cm high stubble, and the straw is crushed to the field evenly. Earlier 1-3 days before the rice harvest, the agricultural drones such as DJI and Jifei are flying rapeseed. They can also fly rapeseed after the rice is harvested. After the rice harvest and rapeseed are sowed, they use mechanical or artificial fertilizer, and use the 1KS (J) -35 dual discus trenches to open the trench, and the ditch is divided into the trunk surface. The ditching direction of drones, the ditching direction of the trenches is consistent with the direction of rice planting, in order to improve the efficiency of the trench, the quality of the ditch, and the seedling rate. Scientific and efficient fertilization. Adjust the fertilization method and fertilization method according to different planting models and different broadcasting periods to achieve efficient and stable and scientific fertilizer.

Live rapeseed high -quality high -quality, high -yield light simple and efficient model. The fertilization method of "planting fertilizer and sowing, one -bottom and one supplement". The side of the fertilizer is deepened, and the strips are applied to improve fertilizer effect. Control the total amount of fertilizer, increase the application of potassium fertilizers, improve the resistance of rapeseed, and reduce the loss of the machine. Sowing in mid-October, the bottom fertilizer can be selected for rapeseed fertilizer (N-P2O5-K2O is 25-7-8, effective B content ≥0.15%) or other similar formula rapeseed Special fertilizer, preferably special fertilizer containing medium-sized element rapeseed fertilizers, 40-50 kg per acre according to soil fertility conditions. The previous stubble is the dry land of corn, soybeans, cotton, melon, vegetables and other crops, and the amount of fertilization of acres can be controlled at 30-35 kg. In the early days of Lei, 2.5-5 kg ​​of urea per acre promoted growth and potassium chloride of about 3 kg to improve the inversion.

The entire rice wheel is returned to the field flying mode. The fertilization method of "bottom application, one fertilizer" is adopted. Sowing in mid-late October, the primer fertilizer can be used for rapeseed mild release fertilizer (N-P2O5-K2O is 25-7-8, effective B content ≥0.15%) or similar formula fertilizer fertilizer, preferably contains medium-sized elements such as MG and S, etc. For rapeseed fertilizers, about 40 kg per mu, 5-7.5 kg of urea per mu in the early days of Lei.

Rape rapeseed is sensitive to boron nutrients. Fields with lack of boron and poor fertilizer in the soil. If the bottom fertilizer is applied to the compound fertilizer that does not meet the requirements of boron, it should be applied per acre 0.5-0.75 kg or uses the same sowing method of fertilizer. Boron-boron fertilizer is 200-400 grams.

Strengthen control. Fields with excessive density during seedlings, leaf surface spray polymidazole enhanced resistance. Winter solstice seedlings are partially prosperous, leaf surface spray -sprayed or polyzole controls to prevent early moss and early flowers and reduce frost damage. Before and after the winter solstice, the growth regulators such as New America Star and Yunxin Suinin are sprayed to enhance the frost resistance of rapeseed and prevent freezing.

Implement green prevention and control. The first is chemical weeding. When the machine is sowed or sow, it is closed to be closed. The heavier field blocks are sprayed in selective herbicides (stems and leaves) in rapeseed 4-5 leaves and weeds 2-3 leaves. For wild mustard, the fields of wild mustard are controlled in the early days of wild mustard. The second is to promote four defense. In the later stage, the "one promotion and four defenses" was implemented with fertilizer drugs such as New America Star, Wo Nong boron boron boron boron boron boron, and phosphate dihydrogen, magnesium sulfate hybrid mortal amine, fluorizolic hydroxylamine and other fertilizers. The fungal disease is retracted the field blocks, and then the drone is then sprayed with drones to spray fluorophythium hydroxylamine, mimonine, potraol, and fungicular nets, and polymorrhols. Prevention. The root swelling disease is easy to do field blocks, and the root anti-rooted disease varieties, mixing with cyanazole, combined with the entire land to improve the soil with 25-50 kg of lime per acre.

Promote mechanical harvest. Vigorously promote the technology of rapeseed machines and reduction and loss, and adopt mechanical (artificial) segmented harvesting or one -time combined machine collection according to local conditions. High -yielded fields and stubble tensioned fields should be harvested in mechanical (artificial) segments. Field blocks that are low -yield or stubble can be collected at one time.

If you harvest segments, the appearance of 70-80 % corner fruit in the whole field is yellow-green or pale yellow. You can use 4SY-2.8, 4GL180 types of rapeseed and sun-cutting machines or manually cutting. 5-7 days, then use the picker to pick up, decarued and clearly selected operations. The quality of the operation should meet the requirements of the total loss rate ≤6.5%, the miscellaneous rate ≤5%, and the crushing rate ≤0.5%.

Joint harvest, the appearance of the rapeseed corner fruits is all yellow or brown, and the maturity is basically the same. When the maturity is basically the same, it can be harvested by the Wedd 4LZY-5.0Z type, starlight 4lz-5.0Z type and other rapeseed harvesters. The quality of the operation should meet the requirements of the total loss rate ≤8%and the miscellaneous rate ≤6%. The height of the stubble should not exceed 25cm.

Rapeseed storage, the harvested rapeseed to dry in time, and actively promote rape dried technology. When the water is ≤9%, enter the warehouse or put it in a cool vent.
