Abstract

The invention discloses a preparation method for a crop zinc increasing zinc-contained organic fertilizer based on soil at a zinc deficient area. According to the preparation method, the zinc-contained organic fertilizer is prepared through cutting off, mixing, spreading, fertilizing, smashing, pelleting, drying and measurement packing. Pig manure with high zinc content serves as a raw material and is mixed with straw to be stacked in an aerobiotic high-temperature mode, an activating agent is added for activating, the activating degree of zinc is greatly improved, the zinc content of crop is increased, accumulation of the zinc element in the soil is avoided, the soil ecological environment deterioration risk is lowered, the current situation that cultivated lands in China are in shortage of zinc can be relieved, the resource utilization of excrements of livestocks can be achieved, and sustainable development of agriculture is promoted.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a method for preparing a zinc-containing organic fertilizer based on zinc-enriched soil and crop zinc in zinc-deficient areas. Background technique [0002] The main reason for zinc deficiency in crops in potential zinc-deficient areas is that there is less zinc in the soil that can be absorbed and utilized by crops, rather than low zinc content in the soil. A lot of research work has focused on increasing the application of zinc-containing micro-fertilizers and adjusting the soil environment. However, due to the limited amount of zinc carried by crops, long-term application of zinc fertilizers will cause the accumulation of soil zinc, which has the potential risk of deteriorating the soil ecological environment. In view of the above-mentioned defects, it is necessary to design a method for preparing zinc-containing organic fertilizers based on zinc-enriched soil and crop zinc in zinc-def...
