Popularizing scientific fertilization is a top priority. Fertilizer promotion expert Fu Jianhe made five suggestions.
In the total investment of farmers, Chemical Fertilizer investment accounts for 48% to 55%. Therefore, using scientific fertilization to improve the utilization rate of chemical fertilizers is an important measure to achieve agricultural cost-saving and efficiency, and must be highly valued by farmers and agriculture-related departments. '' He Jianhe, a researcher at the Hefeijiang Soil and Fertilizer Management Station, said this in an interview. He called for vigorous promotion of scientific fertilization as an important measure to promote agriculture and enrich the people.
According to reports, the current rural fertilizer utilization rate in the country is only about 30%, and only about 200,000 tons of fertilizer waste is caused by the lack of scientific fertilization in rural areas of Heilongjiang Province. Scientific fertilization can increase the fertilizer utilization rate by 3 to 5 percentage points, and the cost per acre can be increased by 30 yuan. Fu Jianhe combined with the status quo of agriculture, and made five suggestions for vigorously promoting scientific fertilization.
First, accelerating the process of industrialization of Organic Fertilizer is the basic work to achieve quality improvement, cost-effectiveness and efficiency. Fu Jianhe believes that there are still some problems that cannot be ignored in the fertilizer input: the ratio of inorganic fertilizer to organic fertilizer application is unreasonable, the formula of chemical fertilizer is unreasonable, resulting in the decline of the quality of agricultural products, which is not the development of quality-efficient agriculture and green food production. Appropriate; the production mode of organic fertilizer is seriously backward, almost staying in the original state, which is extremely unsuitable for the development of modern agriculture; the amount of organic fertilizer is too small, the maintenance of cultivated land is not guaranteed, and it is not related to the construction of ecological agriculture and the sustainable development of agriculture. adapt. In the future, modern biotechnology and low-cost simple equipment should be used to improve the fertilization method of traditional farmyard manure, and to change the past situation of ''potholes, over-circle'' excessive rot, excessive nutrient loss, and poor production environment. . It is necessary to adopt human and animal manure (crop stalk) - biological microbial agent - aerobic fermentation - nutrient complex modulation method, and gradually promote the specialized production of organic fertilizer, commercialized sales, industrialized operation to meet the cultivation and cultivation of cultivated land. Ecological agriculture, the need to produce green food.
The second is to carry out balanced fertilization and increase the utilization rate of fertilizer. Fu Jianhe explained that the so-called balanced fertilization technology, that is, soil testing and formula fertilization, is based on the principle of ''barrel effect'' (minimum nutrient rate), which is irreplaceable for nutrients required for crop growth, so that fertilizer input and cultivation techniques are organically combined. High-tech agricultural practical technology. Balanced fertilization has three major advantages: it can increase crop yield under the same amount or reduce fertilizer input, and receive the purpose of increasing production and upgrading, saving cost and increasing efficiency; improving fertilizer utilization rate, with huge economic and social benefits; preventing groundwater from being nitrated Salt pollution and improving the quality of environmental protection have a positive effect on the development of ecological agriculture and green food production.
The third is to organize in-depth services and establish a scientific fertilization service system for testing, distribution, production and supply. From the perspective of technical implementation, Fu Jianhe believes that the current balanced fertilization work has not completely solved the problem of formula and fertilizer application. Under normal circumstances, there are only two or three formulas in each county, and each formula coverage is too large. . Years of production practice has proved that to promote this technology, it is necessary to establish a sound socialized service system that integrates soil testing, unified formulation, unified fertilizer supply, and unified implementation, and establishes a demonstration base for balanced fertilization technology. Since 2004, Heilongjiang Provincial Soil and Fertilizer Management Station has led the establishment of Heilongjiang Province Balanced Fertilization Technology Industry Collaboration Network. In the past two years, 32 counties (cities) have been selected as demonstration bases (cities) of balanced fertilization cooperation network, and 15 counties have been launched. The laboratory of the Agricultural Technology Promotion Center is a designated laboratory for the cooperative network. It has hired experts from the Provincial Academy of Agricultural Sciences and the Northeast Agricultural University to form an expert advisory group. Some fertilizer manufacturers have been selected as the designated production bases of the cooperative network to make the balanced fertilization work more operational. Sex. Last year, the actual soil testing area reached 1.5 million mu, and 37,000 soil samples were collected and tested. 20 fertilizer formulas were formulated, and 12,000 tons of formulated fertilizer was uniformly supplied. Practice has proved that the establishment of a collaborative network is an effective means to promote balanced fertilization, which can gradually develop the balanced fertilization work in the direction of physical and industrialization, and change the 'sampling, soil unmatched or formula-free fat that appeared in the balanced fertilization work in the past. The '' phenomenon has improved the utilization rate of fertilizers and reduced the production cost, which is very popular among farmers.
The fourth is to push fertilizer technology to improve the level of farmers' scientific farming. Training and guiding farmers to master the scientific fertilization technology, changing the experience of fertilization for formula fertilization, and carrying out deep application and blending before ploughing can significantly reduce the rate of fertilizer loss. The scientific fertilization techniques mainly include: autumn application technology—when the soil is turned flat, the fertilizer is evenly applied to the surface, and then turned to the ground 12-15 cm on the same day. When the ridge is turned over, the fertilizer is applied to the original ditch before the ridge. Then, the ridges and ridges are clamped, so that the fertilizer is concentrated under the ridge, and the fertilizer is best applied in combination with the organic fertilizer in the autumn; the deep application technique of the fertilizer--the dry field combined with the mechanical preparation to apply the chemical fertilizer to below 10 cm, in the top dressing With the use of fertilizers, paddy fields should gradually promote the deep-fertilization technology of mechanical transplanting; the fertilization technology--the fertilizer utilization rate and soil moisture are closely related. In the western part of Heilongjiang Province, there is a habit of sitting in the water, and the water-fertilization technology should be promoted. The conditional plots can be combined with sprinkler irrigation, drip irrigation, Nitrogen Fertilizer and micro-fertilizer technology.
The fifth is to strengthen fertilizer management. First, we must effectively strengthen the management of new fertilizer trials and demonstrations. According to the requirements and regulations of the Ministry of Agriculture on fertilizer management, the testing, demonstration and promotion of fertilizer products should be further tightened, and unregistered fertilizers should not be promoted. Second, we must increase the management of fertilizer advertising. According to the principle of ''Counterfeiting, Supporting, Protecting Agriculture, Protecting Harvest'', the fertilizer advertisements are strictly managed. Each fertilizer advertisement must be carefully reviewed by the provincial soil and fat management station. Once the fertilizer advertisements that are not approved or inconsistent with the approval contents are found The horse limit period is corrected to prevent misleading farmers. Third, we must accelerate the pace of fertilizer legislation. On the basis of further investigation and demonstration, all localities should issue the "Regulations on Fertilizer Management" as soon as possible, and strive to incorporate fertilizer management into the legalized track, so that scientific fertilization can be based on laws to prevent the occurrence of pit farmers.
In the total investment of farmers, Chemical Fertilizer investment accounts for 48% to 55%. Therefore, using scientific fertilization to improve the utilization rate of chemical fertilizers is an important measure to achieve agricultural cost-saving and efficiency, and must be highly valued by farmers and agriculture-related departments.
