Abstract

The present invention relates to a method for producing a special bio-organic fertilizer for saline alkali land improving by using sea-land biological resources, and belongs to the field of fertilizer manufacturing. In order to overcome the disadvantages of too high soil improver cost and to-be-improved effect in the prior art and promote the development of the agricultural circular economy, the present invention provides a method for producing a special bio-organic fertilizer for saline alkali land improving by using sea-land biological resources. According to the method, the high-efficiency and low-cost bio-organic fertilizer is prepared by using manure, straws, seaweed, suaeda glauca (bunge) bunge and other sea-land biological resources through the modern biotechnology means, integrates natural nutrients, anti-biomass and plant hormones, integrates the composite effects of organic fertilizers, microbial fertilizers and seaweed fertilizers, can provide good saline alkali land improving effect, has good application prospects, and can provide important significance for the implementation of the Bohai granary project and the development of the modern agricultural circular economy.

Description

technical field [0001] The invention relates to a method for preparing a special bio-organic fertilizer for saline-alkali land improvement by using marine and land biological resources, which belongs to the field of fertilizer manufacturing. Background technique [0002] The problems of soil salinization and secondary salinization are widespread in the world, and have become resource constraints for the sustainable development of irrigated agriculture in the world. At present, the soil salinization in our country is very serious, which has brought a great impact on agriculture, which is not conducive to the planting of plants, and has brought adverse effects on agricultural resources. In my country's 100 million square kilometers of arable land, about 10% of the land is saline soil. In addition, there are more than 2,000 hectares of salt wasteland, most of which have not been cultivated. How to reclaim and utilize these salinized soils, expand planting area, and increase na...
