Selection of Fertilizer varieties for Formula fertilization of Winter Wheat
According to the production practice of many years in large area, it is an economical and efficient method to apply winter wheat formula fertilizer as base fertilizer (bottom dressing). This kind of wheat field generally shows strong but not prosperous wheat seedlings, developed root system, strong stem, strong disease resistance, large spike and many grains, high 1000-grain weight, and the yield is more than 10% higher than that of traditional fertilization. in addition, the amount of fertilizer is reduced and labor is saved, and the average income per mu is 60 yuan. The economic benefit is very obvious.
The main choices of fertilizer varieties are as follows:
① farm manure. Organic fertilizer such as manure, compost, silt fertilizer and straw is a kind of complete fertilizer, which is rich in organic matter and various nutrient elements, which can not only meet the needs of wheat growth, but also improve the physical and chemical properties of soil.
② fertilizer. Commonly used fertilizers are ammonium bicarbonate, urea, calcium superphosphate, potassium chloride and so on. These fertilizers are cheap, but the nutrients are simple. In the application, it is necessary to mix nitrogen, phosphorus and potassium according to the characteristics of wheat fertilizer. Mixed use, to achieve economic and efficient.
Special fertilizer for ③ formula. In recent years, the pilot project of soil testing and formula fertilization has been carried out in many parts of the country. Through soil testing and testing, and then according to the law of crop fertilizer demand, agrotechnical personnel in various places have prepared special fertilizers, which has solved the problems that it is difficult for farmers to purchase fertilizer and distribute fertilizer.

Weak seedlings and few seedlings of wheat should be fertilized to promote tillering.
After the beginning of tillering, the number of tillers increased with the growth and development of the plant, and the total number of tillers reached the maximum before and after jointing. Since then, the late tillers died one after another due to lack of nutrients, and the number of tillers was basically stable after heading. After the general tiller sprouts

Key points of fertilization techniques for winter wheat
The high yield of wheat is strongly dependent on soil fertility. Wheat fertilization should pay attention to the following aspects: First, the amount of nitrogen fertilizer in wheat fields should not be too large, nor too small. If nitrogen fertilizer is too much in the early stage, it is easy to cause excessive growth in the early stage and yield reduction in the late stage; if nitrogen fertilizer is too much in the early stage, it is easy to cause excessive growth in the early stage and yield reduction in the late stage.
