Polygonatum sibiricum special fertilizer for preventing and treating diseases and insect pests, and preparation method thereof

Abstract

The invention discloses a polygonatum sibiricum special fertilizer for preventing and treating diseases and insect pests. The fertilizer is mainly prepared from urea, diammonium phosphate, potassium sulfate, tobacco stems, rapeseed meal, a fermentation microbial agent, a compound microbial agent A, a compound microbial agent B, micronutrient elements and a nanoparticle synergist. The preparation method comprises the following steps: crushing tobacco stems, weighing the crushed tobacco stems and rapeseed meal in parts by weight, putting the weighed tobacco stems and rapeseed meal into a fermentation tank, adding water, a fermentation microbial agent and a compound microbial agent A, carrying out compost fermentation at 50-70 DEG C for 30 days, and turning once every 7 days to complete fermentation so as to obtain an organic material; and uniformly mixing the organic material, a compound microbial agent B, urea, diammonium phosphate, potassium sulfate, micronutrient elements and a nanoparticle synergist, granulating in a granulator, drying and sub-packaging to obtain the polygonatum sibiricum special fertilizer for preventing and treating diseases and insect pests. According to the invention, the multiple components of the special fertilizer for polygonatum kingianum cooperate to achieve the two functions of increasing the yield of polygonatum kingianum, increasing the content ofeffective components and biologically preventing diseases and killing insects.

Description

technical field [0001] The invention belongs to the field of fertilizers, and in particular relates to a special fertilizer for Rhizoma Polygonatum for preventing and controlling pests and a preparation method thereof.
