Method of planting vegetables in saline-alkali soil

Abstract

The invention discloses a method of planting vegetables in saline-alkali soil, comprising: establishing a planting greenhouse in a saline-alkali plot, applying compound fertilizer to the surface of greenhouse soil, subsoiling, burying micro-wetting tubes, preparing a vegetable bed, broadcasting seeds or transplanting with selected plant spacing and line spacing, and performing field management after seedling emergence or transplanting; the method is used for reforming the saline-alkaline soil. since the used compound fertilizer is special compound fertilizer having microbial activity, the fertilizer can provide fertility constantly and prevent plant disease and insect damage; the greenhouse design enables moisture in air to be utilized and enables automatic adjustment of temperature and automatic light supplementing, and water is automatically supplemented for irrigating and preventing salt return; after planting, economic benefit is created, soil conditions of a planting area are also effectively improved, pH is decreased from original 8.4 to 7.4, nutrients in the soil are significantly increased, alkalization degree is decreased to about 2.3%, soil total porosity is increased to about 48%, and air porosity is increased to about 16%; vegetable yield is high, and disease and pest damage occurrence is low.

Description

technical field [0001] The invention relates to the field of soil improvement in saline-alkali land, in particular to a vegetable planting method in saline-alkali land. Background technique [0002] The ecological restoration and improvement of saline-alkali land is a project that benefits the country and the people. It can increase the area of ​​cultivated land, tap agricultural potential, and is more conducive to the development of the agricultural industry. The improvement methods of saline-alkali land generally adopt physical methods, hydraulic methods, chemical methods, and biological methods. Among them, the first three methods require a lot of manpower and material resources, and the fourth method takes a long time and has slow results. [0003] However, using biological methods to restore and improve the ecology of saline-alkali land can best solve the fundamental problem, so there are more researches in this area at present. Breeding saline-alkali-resistant green p...
