A kind of composite nano germination agent

Abstract

The invention discloses a composite nano germination accelerating agent and a preparation method thereof. The composite nano germination accelerating agent is prepared from the following raw materials: chitosan / polyacrylic acid composite nanoparticles, indoleacetic acid, inositol, ethephon, gibberellin and a traditional Chinese medicine extract. The method comprises the following steps that potassium persulfate, glutaraldehyde and alanine are added into chitosan and acrylic acid so as to obtain the chitosan / polyacrylic acid composite nanoparticles; the traditional Chinese medicine components are taken, and absolute ethyl alcohol is added for ultrasonic extraction so as to obtain a traditional Chinese medicine extract; and the chitosan / polyacrylic acid composite nanoparticles, the indoleacetic acid, the inositol, the ethephon, the gibberellin and the traditional Chinese medicine extract are mixed and dissolved in ethyl alcohol, and water is added for diluting so as to obtain the composite nano germination accelerating agent. The germination accelerating agent has the advantages of being capable of achieving the effects of accelerating germination, promoting growth, inhibiting bacteria and resisting diseases, high in survival rate, high in dispersity, good in slow-release property, capable of being naturally degraded, non-toxic, harmless and residue-free. The preparation method has the advantages of being simple, feasible, high in applicability and high in repeatability, the manual control is easy, the raw materials are few, the efficiency is high, the yield is high, and industrial production is easy to realize.

Description

technical field [0001] The invention relates to the field of agricultural planting, in particular to a composite nano germination agent. [0002] technical background [0003] With the development of agriculture, the rapid growth of seedlings has become an important measure to increase the yield of agricultural, forestry and animal husbandry economic crops. However, due to unsuitable external environment or immature growth of seeds, the seeds have long dormant period, low germination rate and irregular germination. And the low quality of germination seriously affects the growth of later crops, and causes a series of problems such as long production cycle and low product quality, which affects economic benefits. Modern germination techniques mostly use plant growth regulators for germination. In terms of germination materials, it mainly focuses on the germination of seeds, branches, and seedlings. In the selection of germination hormones, cytokinins, gibberellins, and ethylen...
