"A shelling", when the curtain call

"A bombardment", as the name implies, means that the farmers used the entire amount of chemical fertilizers during the whole growing period to obtain a one-time application at the sowing date. Because it saves time and effort, the "one shelled bombardment" fertilization method has been infinitely popular, and has become a direction sought after by many fertilizer companies. However, from now on to the moment, the impact of “one bombardment” on crops and soil environment are emerging. Experts called for a "one bombardment" to have reached the curtain call.

On the occasion of the peak of spring plowing in northeastern China, Xinhua News Agency reporters smelled "dense fertilizer flavor." “Now farmers feel that they have to rely on chemical fertilizers to plant land. We also know that excessive use of chemical fertilizers will cause a decrease in soil fertility and soil compaction, but this is like smoking a big smoke. It feels like it will not work.” Kinds of Tongjiang City, Heilongjiang Province Large grain officials said to reporters. Talking about the use of chemical fertilizers, Liu Junli, a large grain producer in Fujin City, Heilongjiang Province, said that more than 1200 mu of rice will be planted this year, and it is now operating on a scale basis, mainly relying on chemical fertilizers to increase production. Large-scale cooperatives like him use 10% more fertilizer than farmers who use less land. According to the survey, the fertilization methods of these large households invariably chose “one shelling”.

A large family said that when Miao just came out, he really didn't need so much nutrients. Nitrogen fertilizer evaporates easily when he goes to the ground. When the seedlings grow up, the nutrient loss is almost the same, and the real utilization rate of fertilizer is 60%. about. Experts in the industry said that stratified fertilization or staged fertilization can increase the absorption rate of chemical fertilizers by crops and thus reduce the amount of chemical fertilizers. However, some large grain producers have expressed that the manpower cost will be greatly increased and the economic accounts will be calculated. They still choose "one shelling."

With regard to fertilization for farming, these large families face the same difficult situation as "one bombardment."

Experts pointed out that the dilemma of agricultural fertilization in our country has reached a “time of imminent”. Looking at the current situation, the status quo of backward fertilization methods has not been completely changed, and the shallow application of chemical fertilizers, appearances and spreads have become common phenomena. In particular, the corn production areas in the northeast and Huang-Huai-Hai regions adopt a “one-shot” fertilization method. In fact, due to the prevalence of this backward fertilization method, the farmers’ practical use of fertilizers has a low actual efficiency, which not only causes waste of resources, but also leads to more environmental belts. To pressure.

Under the “zero-growth” environment of China's chemical fertilizers, agriculture must go beyond “fertilizer dependence,” and farmers must say goodbye to fertilization. How will this be achieved? Experts believe that in China, we must first strengthen the research on chemical fertilizer innovation and, after scientific determination of soil and environment, produce a good fertilizer that suits China’s agricultural conditions and suits the needs of farmers. We must combine technologies, policies and farmers to promote the transformation and upgrading of the fertilizer industry, change the traditional concept of fertilization, and innovate ideas for the development of agriculture so that the modern agricultural system project can be consolidated from the foundation.

"One shot" has gone through the infinite scenery. Now it is time to call a curtain call. This is the need to safeguard resources, it is also the need to protect the environment, and it is also the need to promote the long-term needs of China's agriculture.
