Alkaline fertilizer

Abstract

The invention provides alkaline fertilizer. The alkaline fertilizer is composed of ammonium chloride, pollen pini, calcium oxide, a polyglutamic acid solution, saw dust, soybean meal, rice hull, diammonium phosphate, urea, calcium carbonate and potassium chloride. Compared with the prior art, the alkaline fertilizer has the following advantages that the alkaline fertilizer can be used in acidifiedsoil, the characteristic of the soil is effectively improved, the permeability of the soil is improved, so that root systems of plants quickly grow, nutrients are fully absorbed, and thus the growthof the plants is promoted.

Description

technical field [0001] The invention relates to an alkaline fertilizer and belongs to the technical field of fertilizers. Background technique [0002] The serious problem of crops "high yield but not high quality, high quality but not high yield" has been plaguing China's agricultural production. In the process of crop production in my country, due to various reasons, excessive application of chemical fertilizers such as nitrogen fertilizers is often used. Although high yields are obtained, long-term large-scale application of chemical fertilizers causes soil acidification. The pH of the soil is crucial to plant growth. Soil acidification can lead to low absorption and utilization of most of the medium and trace elements, serious fertilizer loss, and the fertilizer utilization rate is less than 30%. At the same time, 60-80% of the fertilizer is easy to form insoluble substances. The phosphorus and potassium components in the soil cannot be absorbed, so the crops suffer fro...

Problems solved by technology

The pH of the soil is crucial to plant growth. Soil acidification can lead to low absorption and utilization of most of the medium and trace elements, serious fertilizer loss, and the fertilizer utilization rate is less than 30%. At the same time, 60-80% of the fertilizer is easy to form insoluble substances. Phosphorus and potassium in the soil cannot be absorbed, so the crops are malnourished and the deficiency is serious. Due to the acidification of the soil, the soil micro-ecological environment is changed, and the harmful microorganisms in the rhizosphere multiply under acidic conditions, and it is difficult to control these diseases.
