Guangdong will invest 57.71 million yuan this year to promote the reduction of fertilizers to increase efficiency

Recently, the reporter learned from the Guangdong Agricultural and Rural Department of Guangdong Province that 57.71 million yuan of funds will be arranged in 2022 to promote the reduction of chemical fertilizers in the province. Among them, the basic work of soil measurement formula fertilizer was invested 15.77 million yuan, and the "Sanxin" supporting upgraded version of the "Sanxin" supporting version of the key demonstration county construction investment was 23.85 million yuan, and the application of soil measurement formula fertilization technology was 18.09 million yuan.

Continue to measure the basics of soil formula fertilization

Since the beginning of this year, affected by factors such as international market transmission and rising raw materials, agricultural funds such as fertilizer fertilizer in the province have continued to operate high, and the cost of agricultural production has been raised.

In order to consolidate the foundation of food safety, further promote the fertilization of soil measurement formula and reduce the amount of fertilizer, reduce the cost of fertilization of farmers, improve agricultural quality and competitiveness, and promote the high -quality development of agricultural green. Combined with the actual situation of the province, the Guangdong Provincial Department of Agricultural and Rural Affairs has formulated the "Implementation Plan for Fertilizer Decreasing Fertilization in Guangdong Province in 2022" (hereinafter referred to as the "Plan").

The "Plan" pointed out that in 2022, more than 6,000 soil testing and plant tests were carried out in the province, and more than 400 field trials such as various fertilizers, fertilizer utilization rates were completed, and 11015 households were surveyed by farmers' fertilization. The fertilization database and index system, further improve the application platform of soil measurement formula fertilization guidance, improve the level of digital management level of soil measurement formula, expand the coverage of fertilization and guidance of "cloud" use and intelligent application coverage, so that the promotion area of ​​the province's major crop soil measuring fertilization technology has reached the area of ​​the province 49.36 million acres and the technical coverage rate remained above 90%.

The basic work of fertilizing the soil measurement formula has been arranged for 15.77 million yuan. Among them, farmers' fertilization surveys and soil sample collection funds of 4.77 million yuan, soil sample testing funds of 3 million yuan, field trials, and 8 million yuan.

The "Plan" emphasizes that recently in Guangdong, it is affected by the "Dragon Boat Water" and the "Siam" typhoon. All localities should combine local reality to strengthen the "night to make up early", and use the promotion and application of soil measurement formula fertilizer as "tonight to make up for night. "Early" the main measures to improve the annual grain production. At the same time, Guangdong will summarize, refine and review the county formulas with large number of farmers in recent years, and classify the same formula of similar crops to form a "large formula" for different crops to guide fertilizer companies to produce according to "square". Accelerate the formation of formula fat through agricultural enterprise cooperation.

Strengthening scientific fertilization technology application

At present, the province's chemical fertilizers are still running at a high level, resulting in the general increase in agricultural production costs compared to previous years. The "Plan" emphasizes that the agricultural and rural departments of various places must have bottom -line thinking, based on local food safety, and guide scientific fertilization technologies such as large grain, leading agricultural enterprises, new operating entities, and farmers to promote the use of organic fertilizers, and do everything possible to reduce the amount of fertilizer application. It can effectively reduce the cost of agricultural production and improve planting benefits. Mainly implement organic substitutions through three channels to reduce investment in chemical fertilizers.

The first is straw to return to the field. Guangdong's rice stalk resources are wide and wide, and straw fields are the main way to comprehensively use straw. The results of many tests in the province show that the potassium effect made after the early rice straw is returned to the field, which is 0.0239, that is, after 100 kg of dry straw per pressure, it can be built in the evening. effect. After the early creation of rice, use the drone to spray rotten liquid, and implement the full amount of straw or mechanized straw to return to the field and half -amount to the field, increase organic nutrients, apply formula fertilizer, reduce the amount of fertilizer (especially potassium fertilizers), create to create Straw back field -good breed -soil measuring formula fertilization three supporting demonstration area.

The second is to plant green fertilizer. Use rich winter temperature resources to plant crops such as Ziyunying, Grasson, broad beans, rapeseed and other crops, and inoculate the root tumor. In March of next year, the fresh grass was pressed back to the field. Formulating fertilizer fertilizer was applied to the next crop to form a three -supporting technical model of green fertilizer renewal -Liangye — soil measuring formula fertilization. It is estimated that each ton of green fertilizers can reduce nitrogen fertilizer (N) 1-2 kg, which is a technology worthy of promotion.

The third is to apply organic fertilizer. In the large county of livestock and poultry, the green seed recycling agriculture is implemented, appropriate subsidies are appropriately subsidized to the application of manure, organic fertilizer, and commodity organic fertilizer, and organic fertilizer is applied to large field crops to reduce the application of chemical fertilizers.

Build 15 key demonstration counties

It is reported that, according to the requirements of the Ministry of Agriculture and Rural Ministry, while consolidating the basic work of fertilizing soil measurement, combined with agricultural production custody services, supporting new technologies, new products, and new machinery this year, this year, Guangdong will build 835,000 acres of fertilizer reduction reduction increases increased volume reduction increase this year Effective upgraded version, achieve the goals of "measurement, distribution, production, supply, and application", agricultural machinery integration, reduced fertilizer cost of farmers, and improvement of fertilizer efficiency.

The "Plan" pointed out that this year, the selection of Chenghai District, Shantou City, Gaoming District, Foshan City, Qujiang District, Shaoguan City, Lechang City, Shixing County, Dongyuan County, Heping County, Lianping County, Huiyang District, Huizhou City, Longmen County, Longmen County, 15 counties (cities, districts), including Haifeng County, Lufeng City, Luhe County, Jiangcheng District, Yangjiang City, and Leizhou City as key demonstration counties, focusing on new agricultural business entities, and adopting government purchase services and materialized subsidies. On the crops such as food, vegetables, etc., integrated application of new technologies, new products, new machines, and new services in the application of fertilizers, focusing on promoting soil measuring fertilizer application, side deep fertilization, disposable fertilization and other technologies, and applying organic fertilizer and cropy Fertilizer, slow (control) fertilizer, water -soluble fertilizer, microbial fertilizer and other fertilizer products, and carry out fertilizer -based custody services. It is reported that each key project county arranges 1.55 million yuan in funds to build more than 3 new technologies, new products and new machines supporting zones for fertilization, and deep fertilization+organic fertilizer, slow -release (control) fertilizer fertilization technology with rice side For the focus, the total demonstration is not less than 30,000 mu.

In addition, 21 prefecture -level prefecture -levels in the province choose some counties (cities, districts) to carry out a demonstration of fertilizer reduction and increase efficiency. Strengthen the application of "Dr. Fertilizer", promote new types of fertilizer such as crop fertilizer, slow -release fertilizer, formula fertilizer, and integrate and promote efficient fertilizer application techniques such as drone fertilization and deep fertilizer application.
