Abstract
The invention discloses a particle zinc fertilizer for plants. The particle zinc fertilizer consists of the following compositions in mass portion: 20 to 30 mass portions of zinc sulfate, 25 to 35 mass portions of simple substance sulfur, 20 to 30 mass portions of humic acid, 15 to 25 mass portions of bentonite, and 3 to 5 mass portions of a liquid caking agent. The particle zinc fertilizer consists of a fertilizer core and an envelope, wherein the fertilizer core consists of the zinc sulfate, the simple substance sulfur, the humic acid and the liquid caking agent; and the envelope consists of the simple substance sulfur and the liquid caking agent. The particle zinc fertilizer is a highly-efficient particle zinc fertilizer which is suitable for calcareous soil in north China, and in a culture test of the fertilizer, the particle zinc fertilizer can obviously reduce the pH value of soil by 0.4 to 0.5 unit compared with using common zinc sulfate, and can improve the concentrationof effective zinc in the soil by more than 60 percent.
Description
Technical field
The present invention relates to a kind of plant particle zinc fertilizer.
Background technology
Northern area has irreplaceable effect as China important commodity food and fruits and vegetables production base in assurance China's grain security with aspect uplifting the people's living standard.Yet the northern China various places not only produce fruit tree, vegetables and frequently take place, and also happen occasionally on food crop because the crop failure phenomenon that the effective zn deficiencie of soil causes is more and more serious in recent years.Cause this phenomenon on the one hand because improving constantly of crop yield is increasing to the demand of trace element zinc; On the other hand since northern soil based on alkalescence or calcareous such as brown earth, calcium soil, cinnamon soil, micro-application effect difference causes.
Be subjected to the northern area of China soil pH value and the higher influence of Eh value, soil itself contains a large amount of CO
3 2-And HCO
3 -Ion, very fast formation by soil fixing precipitated after zinc fertilizer was manured into soil on the one hand, or was oxidized into the form that crop can not absorb; On the other hand, the zinc fertilizer that is manured into soil part and macroelement phosphorus etc. interact, and interfix, and cause the dual loss of nutritive element.Generally adopt in the agriculture production in solid fertilizer, add inorganic zinc, the little fertilizer of applicating liquid, the measures such as (EDTA, citric acid, humic acidss etc.) of the little fertilizer of the efficient organic chelated attitude of development improves micro-application effect.Yet these measures all exist obvious deficiency and self unsurmountable limiting factor.Add inorganic zinc as solid fertilizer, soil fixing is obvious, and active low, application effect is poor; The little fertilizer of applicating liquid can not big area be promoted in current agriculture production by factor affecting such as technology, equipment; The little fertile validity of efficient organic chelated attitude is strong, but the production cost height, also can not large-area applications.
The form of trace element zinc is a lot of in the soil, and its activity mainly is subjected to the influence of soil pH value.In general, unit of the every reduction of soil pH, the Zn ionic concn can improve 100 times.The northern area of China big area reduce soil pH improve soil trace element zinc activity be unrealistic also be uneconomic, be feasible but improve micro-application effect by the acidifying of soil film micro area.
Summary of the invention
The purpose of this invention is to provide a kind of plant particle zinc fertilizer, this particle zinc fertilizer can reduce regional soil pH value, improves the application effect of zinc fertilizer in the calcareous soil.
Plant provided by the present invention is used particle zinc fertilizer, is made up of following compositions: the wilkinite of the elemental sulfur of the zinc sulfate of 20-30 mass parts, 25-35 mass parts, the humic acids of 20-30 mass parts, 15-25 mass parts and the liquid-containing binder of 3-5 mass parts; Described particle zinc fertilizer is made up of fertile core and coating, and wherein, described fertile core is made up of zinc sulfate, elemental sulfur, humic acids, wilkinite and liquid-containing binder, and described coating is made up of elemental sulfur, wilkinite and liquid-containing binder.
Wherein, contain the elemental sulfur of 5-10 mass parts in the described fertile core, contain the elemental sulfur of 20-25 mass parts in the described coating.
The preferred group of described particle zinc fertilizer becomes: the zinc sulfate of 25 mass parts, the liquid-containing binder of the humic acids of the elemental sulfur of 30 mass parts, 25 mass parts and the wilkinite of 15 mass parts and 5 mass parts.
Described granulated fertilizer is a round granular, is best with the regular spherical, and particle diameter is 2-3mm.
Described zinc sulfate specifically can be Zinc Sulphate Heptahydrate.
Described liquid-containing binder can be existing any liquid-containing binder.
Particle zinc fertilizer of the present invention is a kind of high-efficient granule zinc fertilizer of suitable northern China calcareous soil, in the fertilizer culture experiment, this particle zinc fertilizer is used common zinc sulfate can obviously reduce a soil pH value 0.4-0.5 unit, and improving in the soil effectively, zinc concentration reaches more than 60%.
