Abstract

The invention discloses organic fertilizer for saline and alkaline land transformation as well as a preparation method thereof. The organic fertilizer for saline and alkaline land comprises 42 to 48 parts by weight of animal waste, 12 to 14 parts of plant straws, 10 to 12 parts of tea powder, 8 to 10 parts of bagasse, 6 to 8 parts of seaweed powder, 4 to 8 parts of a pH regulator, 4 to 6 parts ofan adsorbent and 3 to 5 parts of a loosening agent, and also comprises 1 to 3 parts by weight of microbial agent and 0.01 to 0.03 part by weight of rooting powder. The animal waste, the plant straws,the tea powder, the bagasse and the seaweed powder are subjected to composting treatment, the pH regulator, the adsorbent, the loosening agent, the microbial agent and the rooting powder are added, and pelletizing is performed to prepare the organic fertilizer. The organic fertilizer can effectively improve the soil structure of the saline and the alkaline land, improve the soil fertility and reduce the salinity and alkalinity, cooperates with plant cultivation to improve the water-retaining property of the soil and prevent salt return, can improve the saline and the alkaline land durably andeffectively, and can change the desolate beach into the fertile land after being circulated for many times.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an organic fertilizer for saline-alkali land transformation and a preparation method thereof. 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. Most of the saline-alkali soil is related to the accumulation of carbonate in the soil, the degree of alkalinity is generally high, and plants in severe saline-alkali soil areas can hardly survive. In the process of utilization, saline-alkali land can be simply divided into light saline-alkali land, moderate saline...
