Seed and root soaking agent of brassica chinensis and use method of agent

Abstract

The invention discloses a seed and root soaking agent of brassica chinensis and a use method of the agent. The seed and root soaking agent comprises, by mass, 1-3% of acetic acid, 0.5-1.5% of chitosan, 0.5-1.5% of chitosan oligosaccharides, 0.05-0.2% of gibberellin, 0.005-0.012% of bacillus thuringiensis, 0.2-1.2% of brassinolide, 0.1-0.6% of validamycin, 0.1-0.6% of liquid paraffin and the balance water. Seeds are soaked in seed and root soaking liquid, seedling roots are soaked when seedlings are transplanted, and the seed germination rate, plant growth vigor, protein content, yield and virus resistance of the brassica chinensis are all remarkably improved.

Description

technical field [0001] The invention relates to agricultural chemicals, in particular to a seed-soaking and root-soaking agent of Shanghai green and its application method. Background technique [0002] Shanghai Qing, also known as Shanghai cabbage, Suzhou green, Qingjiang cabbage, green ginger cabbage, Xiaotang cabbage, green stem cabbage, Qingjiang cabbage, rape, and soup spoon cabbage, is the most common cabbage variety in East China around Shanghai. The existing planting methods of Shanghai green are mostly seed coating, and then directly sowing and planting. This treatment method has significant disadvantages: the demand for seeds is large, and artificial clearing of seedlings is required in places where seedlings are densely populated; The occurrence period of diseases and insect pests in the middle and later stages is relatively long from the sowing period, and the pesticides are naturally decomposed in the environment. Moreover, the biomass in the middle and late sta...

Problems solved by technology

The existing planting methods of Shanghai green are mostly seed coating, and then directly sowing and planting. This treatment method has significant disadvantages: the demand for seeds is large, and artificial clearing of seedlings is required in places where seedlings are densely populated; Because the occurrence period of diseases and insect pests in the middle and late stages is relatively long from the sowing period, the pesticides are naturally decomposed in the environment, and the biomass in the middle and late stages of crop growth is too large, so that the concentration of active ingredients distributed in the crops is relatively low. native biodilution

[0004] Because there are many susceptible diseases in Shanghai green, its common diseases include downy mildew, viral disease, white spot, bacterial leaf spot, black spot, black rot, anthracnose, and soft rot. The survival rate and specific disease applicability of Shanghai green are poor, which leads to the problems of high disease rate, low survival rate and poor stress resistance after transplanting Shanghai green
