Why are crops "not high-yield, high-quality, not high-yield"?
One of the serious issues that the times have given us is now before us. Since the reform and opening up, especially in recent years, China’s agricultural production has been harvested year after year, and the total grain output has risen to a new level, from the long-term shortage in the past to a gross balance, which is a historic achievement. However, at present, China's agricultural production has undergone a phased change, and the contradiction in the production structure of agriculture has become increasingly prominent. Adjusting the industrial structure has become an urgent issue. With the continuous harvest of grain production in recent years, China’s grain has been abundant for some years, some poor quality grain varieties have not been sold smoothly, and there is a large inventory of stockpiles. This problem not only causes social waste, but also increases the financial burden; on the other hand, high-quality food Supply exceeds demand, and even need to rely on foreign imports. In addition, poor food quality and other reasons also have a direct impact on farmers' income and crop enthusiasm. Therefore, improving the quality of food has become the key to adjusting the agricultural structure. How to solve the problem of "high-quality, high-quality, low-yield" in agricultural production is an urgent problem to be solved in the new century. From the current point of view, there are mainly two ways to solve this problem: First, selection and promotion of improved varieties, and second, crop nutrient balance and adjustment. The former has attracted the attention and attention of the leadership at all levels and was mentioned on the agenda of governments at all levels. Even Premier Zhu Rongji emphasized at the national food circulation system reform conference that China’s agriculture and rural economy have entered a new phase. It is necessary to use economic levers to promote the adjustment and optimization of the grain planting structure and raise the varieties, quality, and benefits of grain production to a new level. But for the second solution channel, it seems that it has not attracted enough attention. Some soil-fertilizer experts pointed out that crops must have excellent quality, and that the nutrients in the production and result stages must be adequate and well-balanced. This is like a person. In order to be graceful and handsome and stalwart, congenital genes are important, and it is indispensable that the acquired nutrition is fully balanced. However, most farmers in China still follow the traditional cultivation habits and apply large amounts of organic fertilizers such as nitrogen fertilizers. This has led to a reduction in the quality of crops, despite the fact that it is easy and productive. What is the cause of this? The key is the imbalance of agricultural products. This requires a kind of nutritional regulation, what to use it? Some soil fertilizer experts pointed out that silicon-silica fertilizer should be a good regulatory fertilizer, quality fertilizer, and health fertilizer. Experts believe that this is mainly due to the following reasons: First, silicon-silicon fertilizer can improve the sensory effects of color, aroma, and taste. In recent years, people have increasingly complained that fruits and vegetables are not sweet, foods are not fragrant, peanuts are big and small, and the problem of stinking angles in growth, etc. In fact, these are to some extent excessive use of nitrogen fertilizers and imbalances in crop nutrition. Therefore, as a natural inorganic fertilizer, silicon-calcium fertilizer is not only beneficial to crop growth itself, but also can regulate nutrient requirements of nitrogen, phosphorus, potassium, and other elements in different stages of crops, and can reduce the fixation and activation of phosphorus in soil. Phosphorous in the soil, and promote the operation of phosphorus in the crop body, while at the same time when the application of other elements in excess, there is the role of inhibiting the supply. Second, through regulation, the nutrient composition of the crop can be substantially improved, so that the sugar content and Vitamins, peanut fat, grain precipitation, and wheat protein content of the vegetables and fruits can be significantly increased, and the hardness of peaches and plums and other fruits can also be enhanced. The epidermis forms silicified cells and increases the degree of coloration. At the same time, the nutrients of fruits and vegetables increase, and the amount of nutrients absorbed by the body also increases, which alleviates the increasingly widespread human deficiency. The mechanism of the above two aspects is that silicon-silicon fertilizer contributes to the growth of roots and enhances the absorption capacity in the later stage of crop growth. At the same time, it can also close the pores on the surface of plants, reduce the transpiration of water in the plants, ensure the effective supply, and keep the nutrition needed by the crops. Full and even state, not to cause malnutrition due to rapid growth. In addition, silicon-calcium fertilizer causes the crop to form silicified cell walls, increases hardness, helps the orderly arrangement of cell populations, and makes the crop shape perfect. These mechanisms of action, on the surface, lead to a sensational effect of the crop, which is pleasing to the eye. In essence, it is the improvement of crop quality. Third, it can reduce or even eliminate pests and pollution. The pollution is mainly pesticide pollution and heavy metal pollution. Pesticide pollution mainly comes from the prevention and control of crop pests and diseases. The silicon-calcium fertilizer can make the crop produce a harder silicified cell, so that the pathogen is not easily eroded, and pests are not easy to bite. In addition, the silicium-fertilized crops can also emit an odor that pests hate and keep them away from crops. The reduction of pests and diseases also naturally reduces the use of pesticides, thus reducing the pollution of pesticides; the pollution of heavy metals mainly comes from industrial wastewater, especially in the suburban farmland. After the application of silicon-calcium fertilizer in crops, the silicate ions in silicon-calcium fertilizers react with heavy metals such as mercury and lead to form new compounds that are precipitated and not easily absorbed by crops. Simultaneous application of silicon-calcium fertilizers can increase the oxidative capacity of roots, iron oxides , Manganese, to reduce the solubility, thus inhibiting their absorption, effectively prevent iron, manganese poisoning and heavy metal pollution. It can be seen that the application of calcium-silicon fertilizer has a pivotal role in modern agriculture. According to a survey conducted by the Ministry of Agriculture, 60% of China's cultivated land lacks calcium and silicon. This is very much for the present everywhere filled with green agriculture and pollution-free agriculture. Difficulties, therefore, the promotion of calcium-silicon fertilizers and the promotion of balanced fertilization have become urgent issues. In fact, the characteristics of silicon-calcium fertilizers can improve the quality of agricultural products, and has been increasingly valued by the soil fertilization community and the plant nutrition community. For example, Japan holds a nationwide conference on silicon fertilizer in April each year. China’s academic papers on silicon-calcium fertilizers have also increased substantially. Among them, senior engineer Feng Yuanqi, deputy director of the Economic and Technical Committee of the State Bureau of Chemical Industry, wrote an article analyzing silicon fertilizers for crops. Ten mechanisms of action are the most, and at the same time, silicon-silicon fertilizer is ranked first in the "Ninth Five-Year Plan" key scientific and technological achievements promotion project announced by the Ministry of Science and Technology; at the same time, Xu Lei, a well-known rice breeding expert, was on September 13, 2003. At the conference of the “Quality and High Yield New Rice Variety and Rice Fertilizer Technical Appraisal Conferenceâ€, Xu Lei’s researcher gave a high evaluation of the effect of silicon and calcium fertilizers on the quality and yield increase of rice. At the meeting, the director of the Agricultural Department of Liaoning Province, The leaders of the Provincial Bureau of Land Reclamation, the Director of the Provincial General Station for Agricultural Technology Extension, and the Director of the Provincial Academy of Agricultural Sciences also attach great importance to silicon-calcium fertilizers.
