Problems solved by technology

The research and development of crop growth promoters in my country is still in its infancy. With the development of land transfer and intensive management of farms, the integration of water and fertilizer is an inevitable trend. Safe and efficient crop growth promoters will be widely used, but there are still There is no crop growth promoter that matches and connects with the water and fertilizer integration technology

Embodiment 1

[0020] The implementation steps are as follows:

[0021] A. Preparation of solvent

[0022] Prepare a 10% methanol solution in water.

[0023] B. Preparation of organic solutes

[0024] Potassium tripolyphosphate, glycosaminoglycan, maltose oligosaccharide, ammonium tartrate and potassium indolebutyrate are uniformly mixed in a weight ratio of 10:1:2:5:2 to obtain an organic solute.

[0025] C, the preparation of crop growth promoter

[0026] 100 parts by weight of the solvent prepared by step A are added to the reaction kettle, slowly add 20 parts by weight of organic solute while stirring, after continuous stirring for 10 minutes, adjust the pH to 6 with a concentration of 0.5% sulfuric acid, continue stirring for 5 minutes, and then After slowly heating to 50° C. while stirring, continue for 1 hour, then release the liquid in the reaction kettle from the discharge port, and after cooling to room temperature, the crop growth promoter is obtained.

Embodiment 2

[0028] The implementation steps are as follows:

[0029] A. Preparation of solvent

[0030] Prepare a methanol solution with a concentration of 20%.

[0031] B. Preparation of organic solutes

[0032] Potassium tripolyphosphate, glycosaminoglycan, maltose oligosaccharide, ammonium tartrate and potassium indolebutyrate are uniformly mixed in a weight ratio of 10:5:4:10:4 to obtain an organic solute.

[0033] C, the preparation of crop growth promoter

[0034] 100 parts by weight of the solvent prepared by step A are added to the reaction kettle, and 33 parts by weight of organic solute are slowly added while stirring. After continuous stirring for 15 minutes, the pH is adjusted to 8 with a concentration of 1% sodium hydroxide, and the stirring is continued for 10 minutes. Then slowly heat to 60° C. while stirring for 3 hours, then release the liquid in the reactor from the discharge port, and after cooling to room temperature, the crop growth promoter is obtained.

Embodiment 3

[0036] The implementation steps are as follows:

[0037] A. Preparation of solvent

[0038] Prepare a methanol solution with a concentration of 12%.

[0039] B. Preparation of organic solutes

[0040] Potassium tripolyphosphate, glycosaminoglycan, maltose oligosaccharide, ammonium tartrate and potassium indolebutyrate are uniformly mixed in a weight ratio of 10:2:2.5:6:2.5 to obtain an organic solute.

[0041] C, the preparation of crop growth promoter

[0042] The solvent prepared by 100 parts by weight of step A is added to the reaction kettle, slowly add 25 parts by weight of organic solute while stirring, after continuous stirring for 12 minutes, adjust the pH to 6.5 with a concentration of 0.6% hydrochloric acid, continue stirring for 6 minutes, and then After slowly heating to 52° C. while stirring, continue for 1.5 hours, then discharge the liquid in the reaction kettle from the discharge port, and after cooling to room temperature, the crop growth promoter is obtain...

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 [0001] The invention belongs to the field of agricultural science and technology, and specifically relates to a crop growth promoter, its preparation method and application. Background technique [0002] The utilization rate of chemical fertilizers in my country is generally low. The average utilization rate of nitrogen fertilizer is about 30%, the seasonal utilization rate of phosphate fertilizer is about 25%, and the utilization rate of potassium fertilizer is about 50%. At the same time, my country is a country seriously short of water resources. Our country's scientific and technological workers have conducted a lot of research on the ways and methods of improving water and fertilizer utilization efficiency, and achieved good results. Especially in recent years, with the in-depth development of land transfer, labor transfer, and agricultural industrialization, the Ministry of Agriculture has vigorously promoted the integration of water and fertilizer tech...
