Abstract

The invention discloses alkaloid-containing humic acid insect-resistant antibacterial silicon fertilizer and a preparation method thereof, and relates to the field of agricultural fertilizer application. The preparation raw materials comprise 100 parts of humate, 1-20 parts of a silicon-containing compound and 1-20 parts of alkaloid. Alkaloid is extracted and separated from natural plants containing alkaloid, and is obtained by silica gel column chromatography, elution, dissolution and recrystallization. The alkaloid-containing humic acid insect-resistant antibacterial silicon fertilizer combines fertilizer and botanical insecticides, so that nutrient absorption of crops in the growth process is met, and the product can directly promote photosynthesis of crop leaves, form silicified cellsin crop bodies and promote accumulation of crop organic matters, finally achieves the purposes of improving soil, improving crop quality and increasing crop yield, and conforms to the development concept of green agriculture.

Description

technical field [0001] The invention belongs to the application field of agricultural chemical fertilizers, and in particular relates to an alkaloid-containing humic acid insect-resistant and anti-bacterial silicon fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is an indispensable means of production in agricultural production, and my country is the largest fertilizer market in the world. With the continuous increase in the amount of chemical fertilizers used in farmland, the soil quality of the land where chemical fertilizers are applied year after year is generally low, and the phenomenon of soil degradation is serious, and the phenomena of soil erosion, soil desertification, acidification and salinization are still expanding. At the same time, there are many problems in the prevention and control of diseases and insect pests in the field. About 90% of traditional chemical pesticides remain in the environment, which not only causes en...
