Abstract
The invention discloses an organic-inorganic controlled-release fertilizer, and aims to provide a fertilizer capable of simultaneously supplying quick-acting nutrients, long-acting nutrient and slow-acting nutrients to plants. The technical key point of the organic-inorganic controlled-release fertilizer is that the organic-inorganic controlled-release fertilizer is formed by mixing an organic-inorganic compound mixed fertilizer and a controlled-release fertilizer in a compound manner. Through the additive effects of two slow-acting fertilizers, namely an organic fertilizer and the controlled-release fertilizer, the problem that the organic fertilizer or the controlled-released fertilizer cannot meet the heavy demands of the plants for nutrients during the fast growth period of the plants is effectively solved, the fertilization times are reduced, and the labor cost is reduced.
Description
Technical field
The present invention relates to the fertilizer field in the agricultural application, particularly a kind of organic-inorganic controlled release fertilizer.
Background technology
" bread is the staff of life, and food is this with ground, and ground is soul with fertilizer ".Fertilizer plays an important role in crop yield and increasing peasant income always, and the contribution rate of fertilizer in crop production reaches about 50%, is called " grain in the grain ".
Fertilizer comprises organic fertilizer and mineral manure.The human fertilizer that uses the earliest is from organic fertilizer.The organic fertilizer nutrient is comprehensive, fertilizer efficiency is lasting, but nutrient content is low.Along with the development of agriculture production technology, crop yield is more and more higher, and simple application of organic fertilizers nutrient content does not increase, and the peasant operates difficult, increases peasant's labour intensity.In the present stage agriculture production, mainly to use mineral manure.Mineral manure nutrient content height, fertilizer efficiency be fast, use conveniently, but composition is single, fertilizer efficiency short, and be not lasting, and long-term application, easily makes soil acidification, hardens.Adding organic fertilizer in mineral manure is compound organic and inorganic fertilizer, the content of production technology limits product and quality, and effect is general.
Along with the raising of level of agricultural production, the growth of crop yield has promoted the fertilizer amount increase, and the chemical fertilizer nutrient volatilization is run off, and causes pollution of area source serious.China's chemical fertilizer this season utilization ratio nitrogen is about 30-35%, and phosphate fertilizer is about 10-20%, and potash fertilizer is about 35-50%.In order to improve utilization rate of fertilizer, reduce agriculture production cost, the protection agroecological environment guarantees that the peasant continues to increase income, Tenth Five-Year Plan Period, China has carried out a large amount of research to the development and the industrialization of new-type fertilizer, has obtained some important achievement.Novel controlled release fertilizer can effectively be controlled nutrient releasing speed, improves utilization rate of fertilizer to greatest extent.Present controlled-release technology mainly is the dressing of fertilizer; it is to be core with granular chemical fertilizer (nitrogen or compound nitrogen phosphate fertilizer etc.); the top layer applies the inorganic substance or the organic polymer of one deck low water solubility or microsolubility; change the stripping property of chemical fertilizer nutrient; prolong or the release of control fertilizer nutrient, make the supply of soil nutrient and crop need fertilizer to require the new-type fertilizer formulation of coordinating.The popularization of coating controlled-release fertilizer in agricultural obtained certain development, but it makes slow progress, and present production and consumption only are equivalent to about 1% of fertilizer amount.The release and release control fertilizer 92% of developed country consumption is used for non-agricultural market, wherein golf course account for 24%, specialty maintenance lawn 19%, nursery and greenhouse 15%, only 8% is used for high price farm crop such as strawberry, tomato, nut, vegetables, citrus etc.Its major cause: the one, cost an arm and a leg.The international market price of release and release control fertilizer is generally 3-9 times of common fertilizer, the release and release control fertilizer of China's exploitation, and its price generally is higher than common fertilizer more than 15%; The 2nd, effect is general, is difficult to intuitively manifest.Especially can not satisfy heavy demand at the plant vigorous period to nutrient.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the quick-acting of a kind of existing inorganic nutrients are provided, the organic-inorganic controlled release fertilizer of the long-acting of organic nutrient and the slow that controlled release is fertile is arranged again.
This fertilizer is formed by compound organic and inorganic fertilizer and the fertile compound of controlled release, described organic-inorganic controlled release fertilizer forms by containing at least a inorganic nutritive element particulate state compound organic and inorganic fertilizer and containing the fertile compound of at least a nutritive element particulate state controlled release, described organic-inorganic controlled release fertilizer is by the particulate state fertilizer, contain at least a element particulate inorganic fertilizer and contain the fertile compound of at least a element particulate state controlled release and form, described organic-inorganic controlled release fertilizer is by containing at least a inorganic nutritive element particulate state compound organic and inorganic fertilizer, it is fertile and contain the fertile compound of at least a element particulate state controlled release and form to contain at least a element particulate inorganic, and described organic-inorganic controlled release fertilizer is by organic nutrient, the fertile compound granulation of inorganic nutrients and at least a element controlled release forms.
The invention has the beneficial effects as follows: (1) effect is obvious.Efficiently solve single organic fertilizer or singly execute the fat effect of controlled release slow, the shortcoming of DeGrain; (2) cost is low.With the fertilizer instead of part controlled release fertilizer of cheapness, reduce fertilizer application frequency, reduce production costs.
