Abstract

The invention relates to a sweet potato planting fertilizer. The fertilizer comprises an inner layer and an outer layer. The outer layer is prepared by mixing a soil conditioner that is humus and fermented organic matters which are ground into homogenous paste. The inner layer comprises chemical components enveloped by an enveloping agent. The enveloping agent mainly comprises resin, is prepared by adding a cross linking agent, is free of pollution, and forms porous spherical particles after degradation. Nutrients inside are released slowly, thus achieving a high yield while avoiding frequent fertilizing. The outer organic matters can provide rich organic acids and other nutritions after fermentation for sweet potatoes, and is healthier. Added mountain flour can prevent soil hardening, is beneficial to expanding and growth of sweet potatoes, and makes fruits larger, yield higher and economic benefic higher.

Description

A kind of efficient sweet potato plantation fertilizer and preparation method thereof

Technical field

The present invention is a kind of efficient sweet potato plantation fertilizer and preparation method thereof, belongs to the Technology field of fertilizer functional type fertilizer.

Background technology

Chemical fertilizer is that material maximum in agriculture production drops into, statistical information according to Food and Argriculture OrganizationFAO shows, in raising per unit area yield, chemical fertilizer accounts for 40 ~ 60% to volume increase role, but the production time shows, due to the impact of fertilizers for potted flowers material nature and edatope condition and agricultural measures etc., chemical fertilizer utilization ratio is very low.China because of fertilizer nutrient utilization low caused nutrients resource waste very surprising, China produces every year according to statistics, the amount of nitrogenous fertilizer used is about 2,000 ten thousand tons, the this season utilization ratio of its fertilizer only uses 30 ~ 50%, accumulative utilization ratio is 45 ~ 60%, and the direct economic loss caused because of utilization rate of nitrogen fertilizer is amounted to Renminbi and reached 239.4 hundred million yuan.The problem of environmental pollution how to improve the utilization ratio of chemical fertilizer, reducing because improper fertilization causes, Sustainable development high-efficiency agriculture has become the problem that countries in the world are paid close attention to jointly, since 20 century 70s, the research of Slow/Controlled Release Fertilizers and utilization have become the focus of world fertilizer research, slow/controlled release technology is from the inorganics coating large grain carbon ammonium technology of exploratory stage and fertile bag fertilizer technology, develop into the resin packaging technique of present stage, present stage coated with resin technology.

Organic fertilizer is rich in the nutritive substance needed for organic substance and plant growth, can not only provide nutrient needed for plant growth, improvement soil, can also crop quality be improved, improve crop yield, promote high crop yield stable yields, preservation of fertility, can improve utilization rate of fertilizer simultaneously, reduces production cost.Abundant Appropriate application organic fertilizer can increase crop yield, culture fertility, improves quality of agricultural product, improve the validity of soil nutrient.Therefore; organic fertilizer is applied in China; meet the requirement of " Accelerating The Construction resource-conserving and environment-friendly society "; promotion agricultural and resource, Agriculture and Environment and harmony between man and nature close friend are developed; promote agricultural product security, cleaner production from source, preserve the ecological environment all significant.Along with the raising of living standards of the people, the free of contamination demand that is organic, green food of safety of residents health constantly increases, and vast farmers improves the market competitiveness of agricultural-food in the urgent need to application of organic fertilizers.
