NEW TYPE OF FERTILIZER
In recent years, the new special fertilizer in China's fertilizer market unique, out of a different style. The vigorous development of new fertilizers also provides a way out for the transformation of domestic chemical fertilizer: green, ecological and environmental friendliness will be the main direction of the industry. In the new type of fertilizer, the development of slow controlled release fertilizer is particularly outstanding. At present, China has become the largest producer and consumer of slow-controlled release fertilizers, production and consumption is still rising year, at the same time participate in the formulation of international standards, highlighting China's manufacturing power. In addition, the water soluble fertilizer in China has developed rapidly in the past five years. This is closely related to the actual situation of our country and the relevant national policies. With the development of water and fertilizer integration, the development of liquid fertilizers is very rapid. Water soluble fertilizer is a hot spot in recent years, whether from the view of consumption or productivity and output. Liquid compound fertilizer, with its high nutrient content, easy to compound, can be directly absorbed by crops, easy to formula fertilization, drip irrigation and mechanized fertilization, and many other advantages, has attracted more and more attention. Fluid Fertilizer is a liquid product that contains nutrients required by two or more crops. Up to now, there are many varieties of liquid fertilizer, which can be divided into liquid nitrogen fertilizer and liquid compound fertilizer. Liquid compound fertilizers contain all the nutrients needed for plant growth, such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and trace elements, and can also be added to water-soluble organic substances (such as humic acid, amino acids, plant growth regulators, etc.). The formula of liquid compound fertilizer can be designed according to the characteristics of the nutritional requirements required by crop growth.

THE UREA AND POTASSIUM CHLORIDE
Urea is not only a kind of high quality fertilizer commonly used, but also has certain insecticidal effect. Potassium chloride agriculture is a potassium fertilizer. Its fertilizer effect is quick, apply to farmland directly, can make soil substratum moisture rises, have the function of drought resistance. However, it is not suitable to use in saline-alkali land and tobacco, sweet potato, sugar beet and other crops

THE ADVANTAGE OF THE ORGANIC FERTILIZER
Organic fertilizers are carbonaceous materials derived primarily from plants and/or animals and applied to the soil to provide plant nutrients as their primary function. Processed by biological substances, animal and plant wastes and plant residues, it has eliminated the toxic and harmful substances, and is rich in a large number of beneficial substances, including a variety of organic acids, peptides and rich nutrient elements including nitrogen, phosphorus and potassium. It can not only provide comprehensive nutrition for crops, but also increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, which is the main nutrient for green food production. The advantages of the organic fertilizer: 1) the nutrient elements of biological organic fertilizer are complete; Chemical fertilizers contain only one or more nutrients. 2) bioorganic fertilizers can improve soil; Constant use of chemical fertilizers causes soil to harden. 3) bio-organic fertilizer can improve product quality; Too much chemical fertilizer results in inferior quality. 4) bioorganic fertilizers can improve the rhizosphere microbiota of crops and improve the resistance of plants to diseases and pests; Fertilizer is the crop microbial community is single, easy to produce pests and diseases. 5) bio-organic fertilizers can promote the utilization of chemical fertilizers and improve the utilization rate of chemical fertilizers; The use of chemical fertilizers alone can easily cause the fixation and loss of nutrients.
