New compound fertilizer: coated compound fertilizer
The coated compound fertilizer takes granular soluble nitrogen fertilizer as the core, calcium and magnesium phosphate fertilizer as the coating layer, adding potash fertilizer, micro-fertilizer and its mixture, pesticide, herbicide and microorganism to the coating layer, and using nitrogen-phosphorus slurry and inorganic acid compound fertilizer as binder. Plant nutrition complex is made by special coating method. It is characterized by scientific formulation, high utilization rate, controllable release, long-term slow release, quick dissolution, high efficiency, strong pertinence, wide adaptability and convenient use, so it is a leader in the compound fertilizer industry at present. In particular, the developed environment-friendly coated fertilizer, which can greatly reduce soil pollution, further improve fertilizer efficiency and achieve controlled release, is the latest fertilizer in the 21st century. At present, the main products can be divided into three series. 1. Slow-release and long-acting coated fertilizer: it is widely suitable for fertilization of fruit trees and various crops, with high fertilizer utilization rate and remarkable yield-increasing effect. According to the follow-up survey of the Chinese Academy of Agricultural Sciences, compared with the same content of compound fertilizer, the utilization rate of nitrogen, phosphorus and potassium increased by 7. 5%. 24%, 7.2% and 10.4%, respectively. 2. high efficiency potassium sulfate topdressing: the main characteristics are flammable, soluble, no residue, controllable fertilization, and take effect immediately after topdressing for 3 days. It is mainly suitable for fertilization in the middle and late stages of vegetables. 3. Environment-friendly controllable compound fertilizer: the main characteristic is to reduce soil pollution, reduce the times of fertilization, improve fertilizer efficiency and increase yield.

How to apply fertilizer with good effect
More fertilizers are used in crop cultivation, and each has its own characteristics. For example, organic fertilizer and inorganic fertilizer, solid fertilizer and liquid fertilizer, a large number of elements and trace elements, single fertilizer and compound fertilizer and so on. Different fertilizers should adopt different fertilization techniques, and general late-acting fertilizers such as organic fertilizer and compound fertilizer should be used as base fertilizer.

When is the best time to apply wheat herbicide
The first emergence peak and the largest emergence peak of weeds in wheat field appeared 20 days after wheat sowing, and some weeds may have a small emergence peak in March of the following year. Through a large number of experiments and observation, there are three key periods in the period of weed control in wheat field. 1. Wheat is used to control weeds in wheat field after sowing and before emergence.
