How much do you know about the development of fertilizers and their importance for plant nutrition?
China uses 7.8 per cent of the world's arable land to feed 18.7 per cent of the world's population, of which fertilizer is the only contributor. The wide application of fertilizers has led to a rapid increase in grain production, a smooth and effective solution to the problem of food and clothing for the Chinese people, and the modernization of China's agriculture and the process of mechanization have developed steadily. The agricultural industry has experienced traditional organic fertilizers to the current high-efficiency inorganic fertilizers.
and now widely used plant nutrition agent is a kind of liquid inorganic fertilizer, plant nutrition agent contains nutrients needed in various periods of plant growth, is conducive to the healthy growth of plants, improve plant resistance and quality, promote increase in production and income. Reasonable allocation of nitrogen, phosphorus, potassium ratio and the dosage of trace elements, contribute to the high and stable yield of plants, and promote the efficient development of agriculture.
There are also some fertilizer additives that are added to improve the physical and chemical properties of fertilizers. They are important for increasing the utilization rate of fertilizers, improving their performance and quality, reducing the accumulation and spread of harmful substances, reducing the production cost of fertilizers and promoting economic growth. They also contain a certain amount of trace elements or chelating elements, and a small amount of resistant substances that have inhibitory functions on weeds and pests, mixed use with fertilizer. Under the premise of ensuring that the function of fertilizer is not damaged and the fertilizer efficiency is reduced, the physical and chemical properties of fertilizer can be improved to promote the utilization rate of fertilizer, and the soil microbial environment can be improved to provide a good growth environment for plants, and ultimately improve the absorption and utilization of nutrients by plants.
fertilizer is not the right choice to do more harm than good!
Chemical fertilizers can improve the nutrition of plants, but some problems gradually arise during use. At present, the total application amount of chemical fertilizer in China has long been at the highest level in the world, and the highest application amount is vegetables and fruit trees. In order to make plants harvest faster and blindly increase the application dose of chemical fertilizers, if applied for a long time, it will not only reduce soil fertility, cause multiple plant diseases and insect pests, acidification, serious salinity, but also destroy the surrounding ecological environment. It is necessary to choose substances that protect the soil and improve fertilizer efficiency, such as gold-free tillage and SF-pollen polysaccharide, to reduce residues. Because chemical fertilizers contain a lot of nitrogen, phosphorus and other elements, if the surrounding water sources are polluted and the elements are enriched, it may also cause red tides and other hazards, which is not in line with the green environmental protection concept advocated by the country. Plant overnutrition will also cause economic losses due to poor growth.
At the same time, the addition of certain elements may be potentially harmful to the human body. Improper use of chemical fertilizers will reduce the use of chemical fertilizers, resulting in waste of resources and increased production costs. With the increase in demand for crops, the demand for chemical fertilizers will continue to increase, and the problem of excessive application of chemical fertilizers will still be widespread, so measures should be taken from the source. How to balance the relationship between chemical fertilizers and plant nutrition is the problem to be solved.
