Abstract

The invention discloses an organic fertilizer for an improved sandy saline and alkaline land and a preparation method thereof. The organic fertilizer for the improved sandy saline and alkaline land comprises 40-48 parts by weight of animal wastes, 12-18 parts by weight of plant straws, 8-12 parts by weight of bentonite, 8-12 parts by weight of fulvic acid, 6-8 parts by weight of peach pit powder,6-8 parts by weight of tobacco leftovers, 3-5 parts by eight of compound water retention agent and 2-4 parts by weight of sandy soil adhesive and further comprises 1-3 parts by weight of a microbial agent and 0.01-0.03 part by weight of rooting powder. The organic fertilizer is prepared through granulating the animal wastes, the plant straws, the bentonite, the fulvic acid, the peach pit powder, the tobacco leftovers, the compound water retention agent, the sandy soil adhesive, the microbial agent and the rooting powder. The organic fertilizer disclosed by the invention can effectively improvethe soil structure of the saline and alkaline land and increase the soil fertility, reduce the salinity / alkalinity, can also improve the water retaining capacity of soil to prevent salt return in match with plant cultivation, durably and effectively improve the saline and alkaline land and transform a barren beach into a good field after multiple cycles.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an organic fertilizer for improving sandy saline-alkali land and a preparation method thereof. Background technique [0002] Soil salinization and secondary salinization are widespread in the world and have become the resource constraints for the sustainable development of irrigated agriculture in the world. At present, the soil salinization in my country is very serious, which has brought a great impact on agriculture, is not conducive to planting of plants, and has brought adverse effects on agricultural resources. Most of the saline-alkali soil is related to the accumulation of carbonate in the soil, and the alkalinity degree is generally high, and plants in the severe saline-alkali soil area can hardly survive. In the process of utilizing saline-alkali land, simply speaking, it can be divided into light saline-alkali land, moderate saline-alkali ...
