What should I do for agricultural production in the rainy season?The Flood Control Guide of the District Agricultural Committee is here!

According to the forecast of the Municipal Meteorological Center, there are four characteristics of this year's flood season (June-September). One is that the total amount of precipitation is slightly more. The total precipitation during the flood season is 750-950 mm, which is 1-2 % slightly more than the year. It reaches 150 mm; the second is that the amount of rain rain is normal. In the early days of June (earlier than usual), plums in early July, plum rainfall is 230-300 mm; the third is to affect the number of typhoons, which affect the typhoon of the city 2-3 Fourth, the number of high temperatures is normal, the average temperature during the flood season is 27-28 degrees, and the number of high temperature days is 18-26 days. How to do agricultural production during the flood season? Let's look at the suggestions given by the District Agricultural Committee →

Vegetable production management

In order to do a good job of vegetable production, based on epidemic prevention, at the same time, we must do a good job in field management centered on waterlogging and disease prevention. The following technical guidance notice:

1. The technical department strengthens technical guidance. The district vegetable technology guidance unit will timely organize relevant scientific and technological personnel to go deep into gardening fields, vegetable production bases, and cooperatives, etc. according to the weather conditions, and combine the current situation of epidemic prevention to carry out online and offline technical guidance. And strengthen technical training, actively implement various technical measures for disaster prevention and mitigation, and ensure that the measures are strong and the work is in place.

2. The production unit strengthens the management of field vegetables. The first is to open the stains in time. Organize the trenches to reduce stains, reduce the water level in the field, and ensure that the drainage of the cauliflower ditch is unblocked. The second is to do a good job of plowing and loose soil. At present, the water holding the field is high, and the soil should be cultivated during the appropriate soil humidity to prevent the roots from appearing due to the hypoxia of the root system. The third is to pursue it in time. Rain raindation is easy to cause soil loss and poor plant growth. It can use leaf surface topdressing method to replenish fast -acting nutrients such as nitrogen fertilizer. The types of fertilizer fertilizer can be selected. The fourth is to strengthen ventilation and shading management. Do a good job in greenting and dehumidifying the greenhouse in time. At the same time, we must do shading and cooling work under the conditions of sudden sunny conditions to prevent the vegetables from falling in water and withering. The fifth is to do a good job of resumed production after the disaster. The flooded fields should be replaced in a timely manner, and a group of green leafy vegetables such as heat -resistant greens, chicken feathers, Hangzhou cabbage, rice aids, amaranth, lettuce, etc. to ensure the balanced supply of green leafy vegetable markets.

3. Strengthen the green prevention and control of pests and insect pests. High temperature and high humidity climate environment will accelerate the infection of pests and insect pests. Such as soft rot, root rot, epidemic, gray mold, frostmo, blue blight, etc. are all high incidence diseases after rain. At the same time, insect pests such as yellow crank jumping armor and small vegetable moths will also enter the hair period. In terms of prevention and control, we should pay attention to "prevention -oriented, comprehensive prevention and control", and actively adopt green prevention and control technology such as insecticidal lights, sexual seductives, yellow boards, insect -proof nets and other physical, biological biology. Good safe use of pesticide technical guidance and pesticide residue testing for listing vegetables to ensure the quality and safety of vegetables on the market.

The main points of fruit tree management

After entering the rainy season, high -temperature and humid weather will increase the occurrence and spread of fruit trees and insect pests. Therefore, the majority of fruit farmers should strengthen the management of orchards and reduce the loss of the sun after the rain.

1. Timely clear ditch drainage. Fruit farmers should clean up the drainage ditch in time to discharge rainwater in time. Avoid the lack of soil in the orchard due to the long period of water accumulation and high temperature after the disaster, and the rotten roots of the plant.

2. Clean up the orchard in time. It is often accompanied by wind invasion in heavy rain. After the rain, the orchard should be cleared in time. It mainly removes broken branches, leaves, falling fruit, and rotten fruit, and centralized treatment to reduce the source of infection

3. Pruning. Perform the biased and inverted trees in a timely manner, and properly remove some leaves and fruits on the fruit trees with severe injuries to the root system to reduce the steam and reduce the load.

4. Prevent diseases and insect pests. It is necessary to strengthen the comprehensive prevention and treatment of pests and insect pests, focusing on the prevention and treatment of pests and insect pests such as grape cream mold, white rot, peach brown rot, and pear black star disease. In addition, the orchards can apply compound fertilizer once after the rain to enhance the trees. For the unpacking orchard, it should be packed in time after spraying the potion.

5. Pick and sell in time to mature precocious varieties.

Rice production opinion

During the rainy period of Mei Rain, there are more rainwater and large local rainfall. We must use the gap between rainfall to seize the clearance work and do a good job of "flat water"; mechanical acupoint broadcast and artificial live paddy fields must strive for ditch systems, horizontal facilities, and dredge the ditch system in time; mechanical machinery; mechanical machinery; After inserting rice and transplanting, a shallow water layer is established to promote the growth of division. At the same time, the cleanup of the peripheral groove system is grasped to ensure the smooth flow of the field and outside of the field, and avoid the occurrence of live broadcast of phenomena or the lack of phenomenon of the lake of the rice.

Aquaculture management

In the rainy season, high temperature and humidity, continuous rain, and stuffy and low -pressure weather have a great impact on the micro -ecological environment of the breeding pond. At this time, it is the golden period of the growth of aquaculture animals. Various float -plants in ponds grow strongly, the metabolism of the aquatic animals has been strengthened, the bait rate increases, and the growth rate is accelerated. Therefore, we need to pay special attention to changes in the breeding environment and adjust and improve in a timely manner.

1. Strengthen facility maintenance. Comprehensively strengthen key facilities such as various types of ponds, dams, breeding facilities and equipment, and rice fishing comprehensive farming fields, and timely renovate the drainage system of farming ponds and rice fields. Prevent rigid escape fish: Ponds with higher water levels from the outer river should be returned to the water to reduce the water level difference; prevent leakage: timely check and repair the drainage port. The wild mixed fish in the outer pond after flooding the pond will enter the pond, and corresponding measures should be taken to prevent the ecological environment of the pond from being affected.

2. Strengthen breeding management.In the morning and evening patrol ponds, observe the changes in water, water quality, and breeding animal activities, and feeding. It is found that abnormal conditions are treated early. The number of patrol ponds must be increased before and after the rainstorm to ensure the healthy and safe and safe breeding animals.For ponds and rice fields with drainage conditions, timely drainage should be drained to reduce water levels to prevent the ponds.Open the oxygen to maintain sufficient solubility; regulate the water quality to prevent the disease from erupting.3. Adhere to scientific feeding.In the rainy season, the feed is susceptible to the weather and mildew of the weather. When feeding, check the quality of the feed to avoid feeding metamorphic feed.On sunny feeding, nutrition should be strengthened, high -quality feed, and improving immunity and resistance to stress;

4. Pay attention to epidemic prevention and control.Patrol the pond in the morning and evening to observe and analyze diligently, accurately diagnose and use scientific medication, avoid abuse of drugs, and prevent the use of prohibited medicines.River crab ponds use an appropriate amount of lime to improve water quality.The Mei Rain season of catfish farmers should be checked 1-2 times, and it is found that parasites are found in time.
