Abstract

The invention provides an efficient watermelon plating fertilizer according to characteristics of watermelon planting. Vines of fresh crops in life are fermented and then ground into an enveloping component of the fertilizer. Most of the vines and fruit and vegetable waste belong to old leaf parts of crops, are rich in organic matters and various mineral elements, and provide organic acids and the like after fermentation so as to benefit watermelon absorption. Added dolomite particles help grinding, make soil sandy, and allow inner chemical minerals to enter into the soil. The mineral elements comprise NPK bases, and also comprise calcium, boron, iron, magnesium, and other nutrients benefiting watermelon. The fertilizer is enveloped with a specially prepared enveloping agent, and has characteristics of protruding slow release effects, no pollution, capability of avoiding watermelon vine and leaf damage caused by fertilizer spraying due to frequent fertilizing, and capability of increasing economic benefit.

Description

A kind of efficient growth of watermelon fertilizer and preparation method thereof

Technical field

The present invention is a kind of efficient growth of watermelon fertilizer and preparation method thereof, belongs to the Technology field of growth of watermelon high-efficiency sustained-release fertilizer in 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.
