In Lushan, Shanxi Province, there are many chicken farmers who rely on themselves as chicken farmers. They have the advantage of producing chicken fat, regardless of cost. They use chicken fat in the field in summer and autumn, and some seasons. Mu applies 2, 3 cars, individual up to 4, 5 cars, little or no fertilizer. It stands to reason that more fertilization and more production, but their harvest is often not as good as other farmers. What is the reason for this? Since chicken manure is an organic manure, organic fertilizers are characterized by many types of nutrients, including nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and trace elements. However, organic fertilizers contain various types of nutrients but their concentrations In the case of chicken manure, the nitrogen content is about 1.6%, the phosphorus content is about 1.5%, and the potassium content is about 0.9%, that is, 100 kilograms chicken manure nitrogen (N) 1.6 kilograms, phosphorus (P2O5) 1.5 kg, potassium (K2O) 0.9 kg. There are two kinds of role of organic fertilizer: First, improve the soil, fertility and fertility. The main substance in organic fertilizers is organic matter, and the application of organic fertilizers increases the content of organic matter in the soil. Organic matter can improve soil physical, chemical and biological characteristics, ripen the soil, and fertility; Second, increase crop yields and improve the quality of agricultural products, amino acids and other substances, in addition to nitrogen, phosphorus, potassium and other nutrients, but also contains a variety of sugars, amino acids Substances such as these not only provide nutrients to the crop but also promote the activity of soil microbes. However, according to research, roughly every 3 kg of wheat needed to be absorbed by 100 kg of wheat grain, 1 to 1.5 kg of phosphorus, 2 to 4 kg of potassium, and 2 to 4 kg of pure nitrogen are needed for every 100 kg of corn grain produced. Phosphorus pentoxide 0.7 to 1.5 kg, potassium oxide 3.2 to 5.5 kg. As an organic fertilizer, chicken fat has its full-fledged nourishing effect. The rational use effect is really good. However, the proportion of nitrogen, phosphorus, and potassium fertilizers required to produce corn and wheat is seriously distorted by the farmers mentioned above because of their large blind use of chicken fat. The more fat the chicken is administered, the more serious the imbalance is. As a result, wheat is prone to lodging, greedy and late-maturing, and exposed to dry hot winds, which is not conducive to harvesting with other farmers at the same time. This can easily lead to a reduction in production. The scientific application method is: 2000 kg of chicken fertilizer is applied every other acre every year. Then according to the fertility yield and fertilizer application per mu and national large formula fertilizer, the output of corn is more than 650 kg per acre, and nitrogen and phosphorus are applied per acre. The compound fertilizer with potassium content of 18-12-15 accounts for 30-35 kg of base fertilizer, the yield of wheat per acre is between 500-600 kg, and the compound fertilizer with nitrogen, phosphorus and potassium of 15-20-12 is applied per acre. ~ 36 kg is appropriate. In a timely manner topdressing urea about 20 kg. Only organic fertilizers and chemical fertilizers can be used in combination to improve the quality of products and increase production. Blind use of chickens has a lot of advantages and disadvantages, resulting in wastage of funds and production losses in wheat. It is not desirable. For this reason, it is hoped that the majority of farmers should use appropriate amounts of chicken fat.
