Abstract

The invention disclosed a compound fertilizer which comprises basic nutrition fertilizer including nitrogen, phosphorus and potassium, and also comprises gamma-polyglutamic acid and seaweed extract, wherein the gamma-polyglutamic acid accounts for 0.1-2% of the basic nutrition fertilizer, and the seaweed extract accounts for 0.5-2% of the basic nutrition fertilizer. The compound fertilizer containing the gamma-polyglutamic acid and the seaweed extract has high activity biological function, and is capable of improving the yield and the resistance capability such as disease resistance, drought resistance, cold resistance, lodging resistance and the like of crops. Therefore, the compound fertilizer can be widely applied to grain crops such as wheat, rice, corn and the like, and cash crops such as tomatoes, melons, grapes and the like. One-off fertilization can be realized without topdressing, and the yield of the crops can be increased by 10-30%.

Description

A kind of composite fertilizer

Technical field

The present invention relates to contain the composite fertilizer of gamma-polyglutamic acid-and marine alga, belong to the bio-feritlizer technical field.

Background technology

China is global large agricultural country, and the usage quantity of chemical fertilizer is very huge.The use of a large amount of fertilizer and pesticides though solved the supply problem of grain, has improved the output of grain.But the use of chemical fertilizer brings very big environmental problem, and fertilizer utilization ratio is low, the decline of land quality, and water pollutes, and degradation under the resistance of farm crop has threatened agriculture Sustainable development significantly.

Gamma-polyglutamic acid-has physics and chemistry and the biological characteristics of many uniquenesses such as splendid biodegradability, film-forming properties, one-tenth fibering, plasticity-, cohesiveness, moisture retention, can be used for makeup, food, dispersion agent, sequestrant, building coating, dustproof, agriculture field and paying attention to environmental protection, emphasizing today of Sustainable development, gamma-polyglutamic acid-and derivative thereof have very wide application prospect.The production of gamma-polyglutamic acid-can have the technology of biological fermentation to produce on a large scale, can improve the nitrogen nutrition utilization ratio of fertilizer, again plant there is certain water retention, can reduces the required water consumption of plant-growth, be particularly suitable as the functional additive of fertilizer.The marine alga output of China is world-class, account for 60% of whole world ultimate production, Seaweed Extract has the required nutritive substance of various plants growth, have and promote plant-growth, improve quality, improve the effect of output, the needs that are fit to very much current agricultural sustainable development, but starting late of China's marine alga fertilizer research just had about the related products of fresh marine alga as raw material in 2002.Up to the present the production of marine alga fertilizer also is the requirement that does not reach market, and a kind of novel environmental friend fertilizer is badly in need of in China.Therefore, a kind of invention of slow release fertilizer of novel, efficient, environmental protection is necessary and is worth very much.

Summary of the invention

Technical problem to be solved by this invention provides a kind of composite fertilizer that contains gamma-polyglutamic acid-and marine alga.

For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:

A kind of composite fertilizer comprises the basic nutrition fertilizer of nitrogen, phosphorus, potassium, and it comprises gamma-polyglutamic acid-and seaweed extracted liquor, and the quality of gamma-polyglutamic acid-accounts for the 0.1-2% of basic nutrition fertilizer, and the quality of seaweed extracted liquor accounts for the 0.5-2% of basic nutrition fertilizer.

Wherein, in the basic nutrition fertilizer, the nitrogen element accounts for the 0.1-5% of the fertile quality of basic nutrition, and phosphoric accounts for the 0.1-5% of the fertile quality of basic nutrition, and potassium element accounts for the 0.1-5% of the fertile quality of basic nutrition.Basic nutrition fertilizer can be prepared voluntarily by above-mentioned prescription, also can directly buy from the market.The nitrogen element can derive from urea (CO (NH 2) 2), bicarbonate of ammonia (NH 4CO 3), ammonium sulfate ((NH 4) 2SO 4) and ammonium chloride (NH 4Cl) any one in, but be not limited to above-mentioned nitrogenous fertilizer, preferred urea.Phosphoric derives from any one in double superhosphate, calcium superphosphate, ammonium phosphate, fused(calcium magnesium)phosphate and the ground phosphate rock, but is not limited to above-mentioned phosphate fertilizer, preferred double superhosphate.Potash fertilizer derives from Repone K (KCl), vitriolate of tartar (K2SO 4) and saltpetre (KNO3) in any one, but be not limited to above-mentioned potash fertilizer, preferred Repone K.
