发明名称 FACILITY SECONDARY NO3- SALINIZED SOIL MODIFIER, PREPARATION METHOD AND MODIFICATION METHOD
摘要 A facility secondary NO3− salinized soil modifier and a modification method are disclosed. The present invention involves the preparation processes of two biological soil modifiers A and B and application methods thereof, which are specifically described as follows: (1) soil modifier A.: solid, obtained by microbial fermentation with straw powder and rice bran and the like as raw materials. C/N between 30-50, applied by uniformly mixing at 1-1.4% by mass with facility ploughing soil, co-culturing at 35-50° C. for 5-7 days, and then returning to fields; and (2) soil modifier B: liquid, subjected to salt tolerance acclimation to have effective microbial populations, and used in the crop growth period. Based on the microbial techniques, the present invention can improve soil structureness, enhance microbial activity and promote biological immobilization on inorganic nitrogen in soils, significantly increasing the facility cultivation crop yield, and improving the product quality.

主权项 1. A facility secondary NO3− salinized soil modifier, comprising a soil modifier A and a soil modifier B, wherein the soil modifier A comprises the following components by weight: 30-50 parts of straw powder, 10-40 parts of rice bran, 5-20 parts of rapeseed cake, and also an EM stock solution and red sugar, and the weights of the EM stock solution and the red sugar both are 1.2-4.5% of the total weight of the straw powder, the rice bran and the rapeseed cake; and the biological soil modifier B is obtained by acclimation of the EM stock solution by gradually increasing the salt solution concentration, with more than 107 cfu/ml of seeds being obtained.
