Problems solved by technology

Most of the existing fertilizers are chemical fertilizers. The absorption and utilization rate of nitrogen, phosphorus and potassium of the existing chemical fertilizers is generally low, so that the increase in crop yield is limited, and the residual fertilizer is easy to cause soil compaction. If the compacted soil is washed by heavy rain, it will be polluted source of water

Abstract

The invention discloses a solid fertilizer which comprises the following components in parts by weight: 3-5 parts of phosphorus pentoxide, 10-15 parts of polyglutamic acid powder, 15-20 parts of bone meal, 8-12 parts of urea, 3-9 parts of controlled release agent, 1-3 parts of methylene succinic acid, 2-6 parts of growth regulating agent and 9-20 parts of plant straw. The solid fertilizer has the beneficial effects that the buffer performance of soil is improved, the soil is fertilized, production, income and benefits are improved, the soil is not hardened when the solid fertilizer is used for a long time, and the output of crops is greatly increased.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a solid fertilizer. Background technique [0002] Fertilizer is an agricultural product that provides one or more nutrients necessary for crop growth to improve soil properties and soil fertility. It is one of the material bases of agricultural production. Most of the existing fertilizers are chemical fertilizers. The absorption and utilization rate of nitrogen, phosphorus and potassium of the existing chemical fertilizers is generally low, so that the increase in crop yield is limited, and the residual fertilizer is easy to cause soil compaction. If the compacted soil is washed by heavy rain, it will be polluted source of water. [0003] Therefore, in order to solve the above problems, a new technical solution is provided to meet the demand. Contents of the invention [0004] The invention provides a solid fertilizer. [0005] The technical scheme adopted in the present invention is: [000...
