Abstract
The invention provides a crop growth accelerant suitable for a water and fertilizer integration system and a preparation method of the crop growth accelerant. The crop growth accelerant is mainly prepared from potassium tripolyphosphate, glycosaminoglycan, maltose oligosaccharide, ammonium tartrate, indole-3-butyric acid potassium, methyl alcohol and water. The crop growth accelerant provided by the invention is water soluble liquid, can be directly applied in a drop irrigation system, a spray irrigation system or a microspray irrigation system, is added into water according to certain proportion, and is applied to the crop along with the system. The crop growth accelerant takes the methyl alcohol as a solvent and substances like potassium tripolyphosphate as an organic solute, and the crop growth accelerant suitable for the water and fertilizer integration system is prepared through the steps of pH regulating, heating and the like. Tests show that the crop growth accelerant has an excellent accelerating effect on the crop growth, the root activity is improved, the utilization ratio of water and fertilizer and the crop yield are remarkably increased, and secondary pollution is avoided.
Description
Technical field
The invention belongs to agricultural cience and farming techniques field, be specifically related to a kind of plant growth promoter, Preparation Method And The Use.
Background technology
The chemical fertilizer utilization ratio of China is generally lower, and nitrogenous fertilizer average utilization is in 30% left and right, and phosphate fertilizer this season availability is in 25% left and right, and potassium utilization rate is in 50% left and right, and China is the country of a water resource famine simultaneously.The scientific worker of China has carried out large quantity research to improving the methods of water and fertilizer utilization, has obtained good effect.Particularly in recent years, along with the deep development of land transformation, Labor Transfer, agriculture industrialization, the Ministry of Agriculture widelys popularize the Integration of Water into Fertilizer, has promoted the raising of water and utilization rate of fertilizer, save labour and production cost, and promote the raising of China's crop yield.Yet; only rely on water and fertilizer compounding application still can not reach best effect of increasing production; also need fully to excavate and bring into play the productive potential of crop itself; plant growth promoter be the production capacity that can promote crop itself; realize moisture, nutrient supply is coordinated mutually with plant growth; not only crop yield can be improved, also liquid manure utilization ratio, protection of the environment can be increased substantially.
Abroad, particularly the water soluble fertilizer effect of Israel, Norway is very outstanding, its technological core has been used plant growth promoter exactly, the ,Zhong Hua company of MARUBENI of Japan, the second largest Nong Hua HELENA of service company of the U.S. all have a large amount of plant growth promoter technology, but because applying for a patent, enterprise needs information disclosure, enterprise scarcely applies for a patent, and only in inside, uses these technology.China to the research and development of plant growth promoter still in the starting stage, development with the intensive management on land transformation and farm, water-fertilizer integral is inexorable trend, plant growth promoter will be used widely safely and efficiently, but the plant growth promoter that does not also match with the Integration of Water into Fertilizer in the market, is connected mutually.
