Abstract

The invention belongs to the technical field of soil improvement, and concretely relates to a method for repairing secondary salinized soil. The method comprises the following steps: (1) sampling soil, detecting the pH value and the nitrate content of the soil, and broadcasting a bioorganic fertilizer, a high-nitrogen fertilizer and a soil repairing bacterium to the sampled soil; (2) plowing the soil containing the broadcasted bioorganic fertilizer, high-nitrogen fertilizer and soil repairing bacterium, obtained in step (1), in order to make the bioorganic fertilizer, the high-nitrogen fertilizer and the soil repairing bacterium thoroughly mixed with the soil; and (3) watering the plowed soil obtained in step (2) to keep the soil moist, and then planting crops. The method can significantlyreduce the nitrate content of the soil, alleviate secondary salinization of the soil, reduce the dosage of chemical fertilizers, increase the yield of crops, improve the quality of the crops and protect the environment of the soil.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a method for repairing secondary salinized soil. Background technique [0002] Facility cultivation refers to an important cultivation method for vegetable production by using specific protective equipment to artificially create suitable environmental conditions for the growth and development of vegetable crops in seasons or areas that are not suitable for horticultural crops to grow in the open field. Because protected cultivation has played an important role in promoting vegetable production and annual balanced supply in my country, protected agriculture has been widely promoted and applied throughout the country, and has achieved significant economic and social benefits. According to statistics, in 2014, the national vegetable planting area reached 21.289 million hm 2 , of which the facility vegetable area is 3.862 million hm 2 According to the Ministry ...
