Efficient green Chinese onion planting fertilizer rich in microelements and preparing method of efficient green Chinese onion planting fertilizer

Abstract

The invention discloses efficient green Chinese onion planting fertilizer rich in microelements. The efficient green Chinese onion planting fertilizer comprises, by weight, oyster shells, polylactic acid, sodium bentonite, potassium mineral powder, manioc waste, furfural residues, oil residues, saccharomycetes, phosphobacteria, potassium bacteria, cytokinin, a proper amount of hydrogen peroxide, a proper amount of ammonium hydroxide and the like. The potassium mineral powder, the manioc waste, the furfural residues and the oil residues are adopted to be matched with nutrient substances, enveloping controlled release fertilizer is prepared after fermentation, the fertilizer is rich in organic matter, mineral elements and microelements, and nutrients are abundant. An enveloping layer capable of supplying oxygen and dynamically adjusting holes is adopted, the fertilizer effect time is long, organic matter nutrients can be released for a long time, metabolism of green Chinese onions can be promoted, the nitrogen and phosphorus utilization rate of the green Chinese onions is increased, the growth and photosynthesis of the green Chinese onions are promoted, and the utilization efficiency of the green Chinese onions for the fertilizer is improved, green Chinese onion plants are stout and strong in meat quality, the content of proteins, cellulose, mineral elements and microelements is increased, the quality of the green Chinese onions is improved, efficient cultivation of the green Chinese onions is improved, and the green Chinese onions can be widely popularized and applied.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a high-efficiency green onion planting fertilizer rich in trace elements and a preparation method thereof. Background technique [0002] As an important agricultural material, chemical fertilizers have played a pivotal role in increasing food production. Although my country has a large amount of fertilizer, its fertilizer use efficiency is far lower than that of developed countries in the world. In my country's traditional fertilizer fertilization, the utilization rate of nitrogen fertilizer is 30% to 35%, the seasonal utilization rate of phosphorus fertilizer is 8% to 20%, and the utilization rate of potassium fertilizer is about 50%. Most of the nutrients are lost in the air and groundwater with leakage and evaporation. , not only waste serious, but also cause soil, air, groundwater and other environmental pollution. Therefore, modifying fertilizers to improve ...
