Compound agent for rooting, seedling strengthening and tillering promotion of wheat

Abstract

The invention provides a compound agent for rooting, seedling strengthening and tillering promotion of wheat. The compound agent comprises marine biological fertilizer, a plant growth regulator, a bactericide, an insecticide and a solvent, wherein the marine biological fertilizer comprises chitosan oligosaccharide, trace elements, amino acids, micromolecular protein and taurine; and the chitosan oligosaccharide is formed by polymerizing 2-10 glucosamines, the molecular weight of the chitosan oligosaccharide is not larger than 2000 Da, the chitosan oligosaccharide accounts for 0.3%-5% of the compound agent, the trace elements account for 0.5%-1.2% of the compound agent, the amino acids account for 2%-10% of the compound agent, and the micromolecular protein accounts for 5%-10% of the compound agent, the taurine accounts for 0.2%-0.5% of the compound agent, the plant growth regulator accounts for 0.02%-0.04% of the compound agent, the insecticide accounts for 0.5-1% of the compound agent, and the bactericide accounts for 0.4-0.8% of the compound agent. The compound agent is suitable for being sprayed in the early stage, seedling stage and reviving stage of the wheat, can promote thewheat to increase roots, strengthen seedlings and improve effective tillering, can effectively prevent plant diseases and insect pests, and is low in cost.

Description

technical field [0001] The invention belongs to the technical field of agricultural chemistry, and in particular relates to a compound agent for wheat rooting, seedling strengthening and tillering promotion. Background technique [0002] In agricultural production, good seeds, good seedlings, and good harvests. The quality of the seedling stage directly determines the yield in the later stage. Increasing roots, strong seedlings, and promoting tillering are the prerequisites for ensuring stable and high yields of wheat. Spraying the compound agent for one or two times can improve the level of nutrient storage at the seedling stage, regulate the growth of crops, use trace elements and prevent pests and diseases, and resist cold and drought, improve the resistance of wheat to adverse environments, and achieve For the purpose of increasing production, increasing income, and improving quality, a high-nitrogen fertilizer (30-15-10) in the compound is for the second tillering to fo...

[0002] In agricultural production, good seeds, good seedlings, and good harvests. The quality of the seedling stage directly determines the yield in the later stage. Increasing roots, strong seedlings, and promoting tillering are the prerequisites for ensuring stable and high yields of wheat. Spraying the compound agent for one or two times can improve the level of nutrient storage at the seedling stage, regulate the growth of crops, use trace elements and prevent pests and diseases, and resist cold and drought, improve the resistance of wheat to adverse environments, and achieve For the purpose of increasing production, increasing income, and improving quality, a high-nitrogen fertilizer (30-15-10) in the compound is for the second tillering to form big tillers and big spikes. It is also based on the planting methods in recent years that generally adopt one-time fertilization method, leading to mid-to-late defertilization and root topdressing that affects wheat yield
