Abstract
The invention discloses a zinc fertilizer, comprising the following ingredients: 60-90 weight portions of inorganic zinc, 10-40 weight portions of organic zinc, 0-10 weight portions of filling agent, and 0-10 weight portions of binder. The granular zinc fertilizer disclosed herein has quick-acting characteristic and long-acting characteristic. The unique granular design allows the size of the granular zinc fertilizer to be same with composite fertilizer and other granular fertilizers, thus the granular zinc fertilizer is convenient for application. According to the invention, the zinc nutrition status of crops is comprehensively improved, the effects of preventing runt seedling and promoting tillering are obvious, the crop yield is greatly increased, and the product quality is improved. The granular zinc fertilizer has strong effect of diseases prevention, and can enhance the capability of disease-resistant insect pest of crops.
Description
Technical field
The present invention relates to the chemical fertilizer field in the agricultural technology field, relate in particular to a kind of zinc fertilizer and preparation method thereof.
Background technology
In the plant growing process, can the phenomenon that output reduces, quality descends occur in default of certain or a few kinds of nutritive elements, wherein lacking zinc is one of the most general a kind of trace element deficiency.The common feature that crop lacks zinc is: the mesophyll chlorosis, and internode shortens, and clusters, leaflet, and plant is short and small, and growth is suppressed, and causes physiological disturbances such as " stiff seedling ", " grey seedling ", " fruitlet ", and seed, the empty flat rate of fruit are high, yield poorly.To the crop zinc supplementation, can promote crop growth, improve setting percentage, cold-resistant, the resistance against diseases of enhancing crop improve output, improve quality of agricultural product.
Using of zinc fertilizer generally has two kinds of modes: the one, and soil application, the 2nd, foliage applying.Two kinds of nutrients ratios that method of application absorbed have very big difference.The nutrient that soil application provides accounts for 70% even more greatly.Foliage applying is because receive factor affecting such as condition, equipment, large-area applications relative difficult.Therefore soil application is the main mode of crop zinc supplementation.
Traditional zinc fertilizer that is manured into soil; Be main with zinc sulfate mostly; Zine ion wherein may receive the influence of following several kinds of reasons, and the validity of zinc is reduced: pH value soil with high (like calcareous soils such as the calcium soil in the north, cinnamon soil), soil itself contains a large amount of CO
3 2-, HCO
3-ion, the zine ion in the soil are prone to be fixed form and are difficult to the form that absorbed by crop; The plain more rich soil of phosphorus, the zine ion in the soil are prone to again interact with phosphate radical, form the zn phosphate of relatively stable attitude.Above-mentioned factor can make the validity of zinc reduce.
Improving the plain nutrition of zinc of crop whole growth developmental stage, is to make crop obtain high yield and fine assurance.But present existing zinc fertilizer kind is difficult to accomplish quick-acting and long-lasting taking into account.Long-acting zinc fertilizer kind, zinc dissolving slowly are difficult to satisfy the demand to zinc element nutrition in plant growth early stage; And quick-acting zinc fertilizer kinds, early stage, the zinc element nutrition supply was sufficient, but the plant growth later stage is difficult to again guarantee.
The zinc fertilizer of soil application has liquid with solid-state.Liquid its characteristics of zinc fertilizer are exactly that crop reaction is rapid, and effect is fast, but have action time short, be prone to by shortcomings such as rain-out leaching loss, working conditions are restricted; The traditional solid zinc fertilizer, the reaction effect of zinc fertilizer is longer relatively, has the effect of " long-acting " relatively, but for those scarce zinc serious area and the comparatively tangible crop of zinc deficiency, can not in time replenish zinc element again, its " quick-acting " DeGrain.
Therefore, need provide a kind of zinc fertilizer and preparation method thereof to address the above problem.
Summary of the invention
In order to address this problem, the invention discloses a kind of zinc fertilizer, said zinc fertilizer comprises following component: the inorganic zinc of 60-90 mass parts; The organic zinc of 10-40 mass parts; The weighting agent of 0-10 mass parts; The sticker of 0-10 mass parts.
Preferably, said inorganic zinc is one or more in zinc sulfate, zinc chloride, the zinc nitrate.
Preferably, said organic zinc is made up of following component: the inorganic zinc of 50-80 mass parts, the reagent of 20-50 mass parts.

Preferably, said reagent is one or more in trolamine, diethylolamine, humic acids, polyoxy ether, acetic acid, Xylitol, lactic acid, Hydrocerol A, potassium primary phosphate, the biomass char.
Preferably, said weighting agent is one or more in elemental sulfur, wilkinite, the biomass char.
Preferably, said sticker is one or more in aqueous solution of urea, the sticker liquid, and its mass percent is 0.5%.
The invention also discloses a kind of method for preparing above-mentioned zinc fertilizer, may further comprise the steps: at first inorganic zinc, organic zinc, the weighting agent of aforementioned proportion are pulverized and mixed; Place tablets press then, carry out granulation.
Preferably, said tablets press is granulating disc or Squeezinggranulator, when adopting granulating disc, when granulation, need spray sticker, and prepared zinc fertilizer particle grain size is the 2-5 millimeter.
Particle zinc fertilizer of the present invention has following characteristics:
1) with quick-acting and long lasting characteristic.After the use, both can in time alleviate the crop zinc deficiency symptom, and can the long period (the 3-6 month) provide zinc plain nutrition again crop;
2) unique particulate state design, particle diameter 2-5 millimeter, consistent with granulated fertilizer size such as composite fertilizer, conveniently use;
3) improve the crop zinc nutrition comprehensively, prevent stiff seedling, the effect that promotes to tiller is obvious, increases substantially crop yield, improves quality of agricultural product;
4) has stronger prophylaxis effect, the diseases and insect pests resistance of ability enhancing crop.
In the summary of the invention part, introduced the notion of a series of reduced forms, this will further explain in the embodiment part.Content part of the present invention does not also mean that key feature and the essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection domain of attempting to confirm technical scheme required for protection.
