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 technical field of agriculture science, be specifically related to a kind of crop growth accelerant, Preparation Method And The Use.
Background technology
The chemical fertilizer utilization ratio of China is general lower, and nitrogenous fertilizer average utilization is about 30%, and phosphate fertilizer this season availability is about 25%, and potassium utilization rate is about 50%, and China is the country of a water resource famine simultaneously.The scientific worker of China has carried out large quantity research to the methods improving water and fertilizer utilization, achieves 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.But; only rely on water and fertilizer to use and still can not reach best effect of increasing production; also need the productive potential fully excavating and play crop itself; namely crop growth accelerant is the production capacity that can promote crop itself; realize moisture, nutrient supply is coordinated mutually with plant growth; not only can improve crop yield, also can increase substantially liquid manure utilization ratio, protection of the environment.
Abroad, particularly the water soluble fertilizer effect of Israel, Norway is very outstanding, its technological core is just the use of crop growth accelerant, the second largest Agro-chemistry service company HELENA of Japanese MARUBENI, Zhong Hua company, the U.S. all has a large amount of crop growth accelerant technology, but need information disclosure because enterprise applies for a patent, enterprise scarcely applies for a patent, and only uses these technology in inside.The research and development of China to crop growth accelerant are still in the starting stage, with the development of the intensive management on land transformation and farm, water-fertilizer integral is inexorable trend, crop growth accelerant will be used widely safely and efficiently, but the crop growth accelerant also not matching with the Integration of Water into Fertilizer, be connected mutually in the market.

| Process 3 | 591.7 | 263 | 18.82 |
Above-mentioned result of the test: compared with conventional treatment, using crop growth accelerant of the present invention significantly can increase the grain number per spike of corn, 100-grain weight and grain yield.The corn yield of process 1,2,3 comparatively contrasts increase by 10.8%, 16.8% and 13.3% respectively.
test example 3: add the impact of described crop growth accelerant on Ginger Yield
This test is carried out in Qingzhou City Dong Xia town, and test arranges 4 process (process 1: conventional Capsicum yield; Process 2: conventional liquid manure+C-1; Process 3: conventional liquid manure+C-2; Process 4: conventional liquid manure+C-3.The ratio of crop growth accelerant and irrigation amount is 1:1000), each process 3 row (line width: 0.75m × row is long: 20 meters) ginger, repeats 3 times.The irrigation quantity of often going is 1 ton/time, and liquid manure is together used, and uses 3 times altogether, and each fertilizing amount is 8kgN, 4kgP
2o
5, 4kgK
2o, fertilizer variety is urea, diammonium phosphate and potassium chloride.
Table 3 crop growth accelerant is on the impact of Ginger Yield
| Process | Output (kg/ mu) |
| CK | 8047 |
| Process 1 | 10190 |
| Process 2 | 11508 |
| Process 3 | 10924 |
Compared with conventional treatment, use the output that crop growth accelerant of the present invention significantly can increase ginger.The Ginger Yield of process 1,2,3 comparatively contrasts increase by 26.6%, 43.0% and 35.8% respectively.
As can be seen here, when fertilizer amount is identical, applying crop growth accelerant of the present invention can significantly increase maize grain yield and Ginger Yield.
