Abstract
The invention relates to a synchronous nutrient wheat special controlled release fertilizer and a preparation method thereof. Double-layer diolame urea, double-layer diolame potassium nitrate and double-layer diolame diammonium phosphate prepared by utilizing recycled waste thermoplastic resin and thermosetting resin are compounded with potassium chloride compound fertilizer and zinc sulfate, and the nutrient release and the wheat absorption of the prepared wheat special controlled release fertilizer in soil are synchronous, so the fertilizer is suitable for mechanical application and has no harm on the seeds.
Description
Technical field
The present invention relates to a kind of wheat special controlled release fertilizer, wheat special controlled release fertilizer and the preparation method thereof that mechanical fertilization, nutrition release and wheat nutrition absorption are synchronous carried out, is applicable in particularly a kind of and sowing simultaneously, belongs to the release and release control fertilizer production technical field.
Background technology
Wheat is one of staple food crop of China, and still, the wheat planting benefit is low, and the peasant is unwilling to drop into too much labour and time, realizes that wheat cultivation and disposable the finishing of fertilising are the developing direction of wheat fertilizing.At present, the fertilizer that wheat is used is based on the quick-acting chemical fertilizer, and this fertilizer is because dissolving is fast, fertilizer efficiency is short, easily run off, can not single fertilization, more can not use with sowing.Controlled release fertilizer can solve wheat single fertilization problem, a kind of " sulphur, resin film coated wheat special-purpose control-release fertilizer and manufacture method thereof " disclosed as Chinese patent file CN101182260A (200710114006.1), the fertile method of the serial controlled release that utilizes sulphur, resin coating material to produce by composite production wheat special controlled release fertilizer, but also there is deficiency in it, sulphur easy oxidized becoming fragile in air for example, in the nutrient dispose procedure breaking of putamina can be taken place, cause the unexpected release of nutrient in the film etc.The patent of invention CN 100567222C that authorizes on December 9th, 2009 " reclaims the production method of thermoplastic resin and thermoset multi-layer composite coated controlled-release fertilizer " and has realized coated fertilizer toughness and elastic perfect adaptation, and the controlled release properties and the nutrient release that have solved fertilizer are influenced and the problem of big ups and downs by production environment.But this technology can only be produced universal slow-release or control-release fertilizer, also has certain gap at wheat.
At present, the controlled release phase of wheat controlled release fertilizer selects also to exist bigger blindness, and it is tentatively definite with the readily avaiable fertilizer to be that the effect of increasing production (or utilization rate of fertilizer) of contrast controlled release fertilizer waits usually, and the online detection of this method and controlled release fertilizer suitability for industrialized production can't quantitatively be got in touch.China's slow-release or control-release fertilizer production standard regulation begins to represent to the required time of nutrient cumulative release rate that reaches 80% with lixiviate in 25 ℃ of hydrostatic the time of releasing of slow controlled release nutrients.This method for expressing is produced significant to the standard slow-release or control-release fertilizer, still, the environment of wheat growth is a soil, and its temperature and moisture have bigger variation, and temperature and moisture are two principal elements that influences release of controlled release fertilizer nutrient.Therefore, determine that with the controlled release phase and the wheat growth phase of slow-release or control-release fertilizer production standard regulation using of controlled release fertilizer can have than big gap with production is actual.
Summary of the invention
At the deficiencies in the prior art, the invention provides wheat special controlled release fertilizer of a kind of synchronous nutrient and preparation method thereof, utilize to reclaim the double-deck coating controlled-release fertilizer of waste thermoplastic resin and thermosetting resin carry out composite, the wheat special controlled release fertilizer that makes be applicable to utilize seed sower, machinery is used when wheat cultivation.

Wheat special controlled release fertilizer of the present invention is the prescription of the nutrient release conditions of controlled release fertilizer in soil of nutrient demand rule and different membrane wrapping thicknesses being formulated according to wheat.
The consumption of wheat special controlled release fertilizer of the present invention and fertilizing method: consumption is generally 25～35 kilograms every mu, also can local peasant habit rate of fertilizer application do reference, and its consumption is the 50-60% of common chemical fertilizer.Fertilizing method is to utilize sowing, fertilising integrated machine to finish.The fertilizer application position can be in seed one side, also can be below seed.Preferred 2～3cm below seed.
Excellent results of the present invention is as follows:
1. do not endanger seed
Release and release control fertilizer of the present invention is for reclaiming the double-deck coating of thermoplastic resin and thermosetting resin, two kinds of coated fertilizers are non-water soluble substance, can not change the nutrient release performance because of the variation of soil moisture, simultaneously, this special-purpose control-release fertilizer has been brought into play the advantage of two class coated fertilizers, realized toughness and elastic perfect adaptation, also can be even if directly contact to seed generation harm with seed.This fertilizer is also referred to as seed nurse fertilizer.
2. synchronous nutrient, controlled release fertilizer nutrient discharge to absorb with wheat and match
Wheat special controlled release fertilizer of the present invention is that controlled release fertilizer according to the different membrane wrapping thicknesses nutrient element releasing rule and the wheat of (rather than on the common meaning 25 ℃ water in) in soil need combine formulated to nutrient absorbing, the field practical situation that its controlled release fertilizer of determining with fertilizer releasing period in 25 ℃ of Static Water commonly used is more pressed close to wheat growth, therefore, the nutrient of controlled release fertilizer discharges with the nutrition absorption of wheat more identical.
3. fertilizer is near apart from root system, the utilization ratio height
This special-purpose control-release fertilizer can be executed near seed, neither can damage seed, is beneficial to root system again and absorbs, and has greatly improved utilization rate of fertilizer.According to the study, compare, can improve nearly 1 times of utilization rate of fertilizer with the normal conventional fertilising.
4. use conveniently, save labor
This special-purpose control-release fertilizer can utilize machinery to finish with wheat cultivation is disposable because coating is even, and appearance character is good, has avoided manually spreading fertilizer over the fields fertilizer, greatly reduces peasant's labour intensity, has saved the recruitment cost, has improved economic benefit.
