Rice fertilizer

Abstract

The invention discloses a rice fertilizer which is composed of the following raw materials in parts by weight: 10-30 parts of urea, 10-15 parts of diammonium bicarbonate, 10-20 parts of potassium chloride, 10-15 parts of potassium sulfate, 5-15 parts of zinc sulfate, 5-10 parts of diammonium phosphate, 5-10 parts of nitro-humic acid, 1-5 parts of ammonium chloride, 2-5 parts of calcium-magnesium phosphate fertilizer, 2-6 parts of ferrous sulfate, 1-5 parts of silicate mineral powder, 20-60 parts of glycerin, 18-30 parts of calcium superphosphate and 1-5 parts of borax. The invention provides the rice fertilizer which is scientific in formula, reasonable in nutrient, capable of improving utilization rate of fertilizer during use for rice cultivation, and resistant to lodging and insect pest, increases yield of rice, and improves quality of rice.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for rice. Background technique [0002] Rice is an important commodity grain in my country. It has the characteristics of wide planting area and large area. In addition to self-sufficiency, some of it can be exported every year, which is of great significance to my country's food security. Therefore, rice production has always been a hot field of research. In recent years, with the large-scale promotion of hybrid rice and super rice, due to the phenomenon of partial application of chemical fertilizers and imbalance of various nutrients in the process of domestic rice planting and fertilization, it cannot meet the needs of various stages of rice production. At the same time, in the process of applying nitrogen fertilizer, it is easy to cause problems such as excessive growth of rice seedlings, easy lodging, serious occurrence of various diseases and insect...

Problems solved by technology

In recent years, with the large-scale promotion of hybrid rice and super rice, due to the phenomenon of partial application of chemical fertilizers and imbalance of various nutrients in the process of domestic rice planting and fertilization, it cannot meet the needs of various stages of rice production. At the same time, in the process of applying nitrogen fertilizer, it is easy to cause problems such as excessive growth of rice seedlings, easy lodging, serious occurrence of various diseases and insect pests, and yield not reaching the ideal level. The emergence of these problems also seriously limits the high-yield and high-quality production of rice.

Therefore, many related products have appeared on the market to solve the above problems, but these products have a single function, improper use is likely to cause negative effects, and at the same time, the residues in the soil are serious, which is easy to affect the subsequent crops, and cannot meet the needs of rice. The nutrients required at each stage of the production process lead to low fertilizer utilization, nutritional imbalance, lodging, yield reduction, and quality decline of rice crops. At the same time, the soil properties of cultivated land deteriorate and seriously pollute the environment.

The potential of rice production and the efficiency of natural resources such as soil cannot be brought into full play, which limits the increase in rice production and cannot satisfy farmers
