Fertilize as objects
In agricultural production, fertilization is indispensable, especially the application of chemical fertilizers, which plays a major role in modern agricultural production. Rational fertilization can promote the normal metabolism of crops, increase the yield of crops and the resistance of crops. Improper fertilization can lead to crop maladjustment and lead to the occurrence of pests and diseases. In general, excessive application of nitrogen will cause the crop to have a dark green leaf color. Most of the carbohydrates are used for nitrogen assimilation, the synthesis of cellulose and lignin is reduced, the plants are long and soft, and they have weak lodging resistance. There is more accumulation of soluble nitrogen and crops are susceptible to disease. The excessive nitrogen fertilizer resistance also weakened correspondingly. Reasonable application of nitrogen, phosphorus and potassium combined with additional boron, zinc, manganese and other trace elements can promote the physiological metabolism of crops, enhance the plant's resistance, reduce the occurrence of pests and diseases. For example, phosphorus can promote the development of crop roots, and boron and manganese can reduce the occurrence of cotton brown wilt. The application of appropriate amount of potash fertilizer in soils that are deficient in potassium can generally reduce fungal and bacterial diseases, and have certain effects on pests and aphids. In general, when the potassium supply is appropriate, the occurrence of rice leaf spot, leaf blight, rice blast, and sheath blight can be reduced. Wheat scab, sheath blight, powdery mildew, wheat rust. Reduce corn smut, leaf spot, and large spot disease. Orange yellow dragon disease, apple rot disease and so on. The reasons why potassium can enhance crop resistance to pests and diseases can be explained from two aspects: crop tissue characteristics and biochemistry. Potassium can increase the thickness of cell epidermis, promote lignification of cells, improve the tissue structure of cells, and enhance the ability of crops to resist pests and diseases. Since potassium can promote the conversion of amino acids, it is beneficial to the synthesis of proteins, thereby reducing the accumulation of amino acids, so it can reduce the bacterial infection. In addition, reasonable fertilization also can prevent and control the deficiency of the crops. Rice deficiency leaves often occur brown spots. The lack of boron in cotton shows "bristle but not flowers" disease. The lack of boron in rape shows "flower but not real" disease. It is characterized by "white bud disease" and "dwarf disease" in zinc deficiency in rice. Rational fertilization can not only reduce pathological diseases, but also prevent and treat physiological diseases. Reasonable fertilization is a scientific, scientific and reasonable fertilization, not only can increase crop yield, but also can enhance the resistance of crops, effectively reduce the occurrence of pests and diseases, reduce the use of pesticides, and achieve high-yield and efficient ecological agricultural production. Food additive is indispensable in food, food manufacturers need to add the food additives in the production process, in order to change the food color, smell, or adjust the taste of food, and for a time, such as Preservatives and antioxidants, and Sweeteners, such as these are most of food additives, plant extracts, through professional technology of extraction, There are many kinds of food additives, mainly: preservatives, colorants, sweeteners, spices, leavening agents, acidity regulators, antioxidants, thickeners, emulsifiers and Food Additives,Tbhq Active Ingredients Powder,Custom Citric Acid,Useful Plant Extractpowers so on.
