Special fertilizer for maize in saline and alkaline land

Abstract

The invention relates to a special fertilizer for maize in a saline and alkaline land. The special fertilizer is characterized by being prepared from, by mass, 15-20 parts of livestock excrement, 15-20 parts of zeolite, 10-20 parts of crop straw powder, 5-10 parts of microbial floras, 5-10 parts of humic acid, 10-15 parts of vinegar residues, 10-15 parts of urea, 5-10 parts of a phosphatic fertilizer, 5-10 parts of a potassic fertilizer and 2-5 parts of trace elements. The prepared special fertilizer can improve the physicochemical structure of soil, improve air permeability and water retention of the soil, neutralize the salinity and alkalinity of the soil, improve the microbial ecosystem of the soil, maintain the growth environment of crops, maintain the balance and comprehensiveness of nutrition, improve the fertilizer maintenance capacity of the soil and the drought resistance of the crops and have an obvious yield increase effect.

Description

technical field [0001] The invention relates to the technical field of soil improving fertilizers, in particular to a special fertilizer for corn in saline-alkali land. Background technique [0002] Maize (Latin scientific name: Zea mays L.) is an annual herbaceous plant of the Poaceae Zea genus. It is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food crop and feed crop. crops, its planting area and total output are second only to rice and wheat. Corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrition, high-biological function foods. [0003] The suitable soil pH for corn is 5-8, and its salt-alkali tolerance is poor. Fertilizers are usually used for soil improvement during the planting process. However, the existing corn-specific fertilizers have imbalanced nutrients and cannot improve the soil microbial ecosyst...

Problems solved by technology

[0003] The suitable soil pH of corn is 5-8, and its salt-alkali tolerance is poor. Fertilizers are usually used for soil improvement in the planting process. However, the existing corn-specific fertilizers have imbalanced nutrients and cannot improve the soil microbial ecosystem. As a result, soil fertility and water retention cannot be effectively improved, and the effect on increasing crop production is limited
