Abstract

This invention discloses a method for preparing chito-oligosaccharide/seaweed fertilizer composite biological agent. The composite biological agent is composed of: chito-oligosaccharide 0.2-3 wt. %, seaweed fertilizer 0.5-3 wt. % (according to alginic acid weight), buffer solution (pH = 5-8) 1-30 wt. % (according to solute weight), and water as balance. The composite biological agent has improved drug efficiency and fertilizer efficiency, and can prevent and treat plant disease. Besides, the composite biological agent is environmentally friendly.

Description

technical field [0001] The invention relates to a compound preparation of biological pesticide and biological fertilizer and a preparation method thereof. Background technique [0002] Chitooligosaccharides are used as biological pesticides, and seaweed fertilizers are used as new biological fertilizers. They have the characteristics of strong pertinence, low dosage and high value in plant protection and nutrition. They are the first choice for the development of precision agriculture, irrigation agriculture and pollution-free agriculture. Very It is suitable for the needs of the sustainable development of agriculture at present. [0003] Chitooligosaccharide is a substance with high solubility, special biological activity and easy absorption obtained by degrading chitosan; seaweed fertilizer is derived from seaweed extract, which is a natural multi-effect plant fertilizer, rich in protein and amino acid , carbohydrates, inorganic salts, vitamins, plant hormones, polyphenol...
