Burning-free fertilizer special for corn

Abstract

The invention discloses a burning-free fertilizer special for corn. The burning-free fertilizer is prepared from the following raw materials in parts by weight: 8-11 parts of withered tree leaves, 50-55 parts of sugar beet pulp, 6-7 parts of pollen pini, 2-3 parts of calcium lignosulphonate, 5-7 parts of calcium nitrate, 1-2 parts of trisodium phosphate, 2-4 parts of potash feldspar powder, 28-30 parts of waste newspaper, 1-3 parts of potassium peroxodisulfate, 34-37 parts of yellow mealworm dung, 0.8-1.0 part of ferric chloride hexahydrate, 0.4-0.6 part of ammonium ferrous hexahydrate, a defined amount of 25% phosphoric acid solution and a defined amount of water. According to the invention, the fertilizer nutrient proportion is scientific; the degradation of the fertilizer in the soil can be effectively controlled in the manner of pelletizing wrapping; the effective period of the fertilizer can be prolonged; the degrading speed can conform to a nutrient absorbing curve of the corn; the growth retardation caused by insufficient nutrition can be prevented; the phenomena of resource waste, seed burning and seedling burning caused by excessive nutrient release can be avoided; the safety of the seeding of the corn plant can be promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special burn-free fertilizer for corn. Background technique [0002] my country is a large agricultural country, and the amount of fertilizer used is extremely high. However, the current fertilizer and its corresponding fertilization technology have kept the fertilizer utilization rate in my country at a low level for a long time, seriously affecting the enthusiasm of farmers for planting, and causing serious pollution to the environment. , It is not conducive to the construction of an efficient and high-yielding modern industrial technology system for sustainable development in my country. Based on national food safety requirements and high-yield goals, the use of chemical fertilizers has continued to increase. Some farmers' blind fertilization has caused soil, water quality, and crop pollution, decreased fertilizer efficiency, and increased food costs. Therefore, it is of...
