However, the utilization rate of crops to chemical fertilizers is low, the utilization rate of N fertilizer is 30-35%, and the utilization rate of P fertilizer is 10-20%, which will inevitably cause environmental pollution of chemical fertilizers. Soil structure damage and soil fertility decline, as well as water eutrophication problems are irreversible

Embodiment 1

[0019] A disease-resistant fertilizer for strong seedlings at the seedling stage, characterized in that it is made of the following raw materials in parts by weight (Kg): rice husk 45, 20wt% NaOH solution 130, imidacloprid granules 25, borax 12, chitosan solution 16, EDTA chelated zinc 5, succinic acid 1, potassium permanganate 16, tobacco powder 22, gypsum powder 32, phosphate rock powder 20 and appropriate amount of water.

[0020] A preparation method of a strong seedling disease-resistant fertilizer at the seedling stage, characterized in that it comprises the following steps:

[0021] (1) First crush the rice husk, crush it into 10-20 mesh sieve particles, put it into a muffle furnace, heat it to a temperature of 600-800°C under airtight conditions, and continue carbonization for 6-8 hours to obtain a carbonized product;

[0022] (2) Mix the carbonization product described in (1) with 20wt% NaOH solution, put it into a reaction kettle, heat it to 100~120°C, and keep it wa...

Abstract

The invention discloses a disease-resistant fertilizer for strong seedlings in seedling stage and a preparation method thereof. The fertilizer is prepared from the following raw materials (by weight): rice hull, 20wt% NaOH solution, imidacloprid granules, borax, a chitosan solution, EDTA chelated zinc, succinic acid, potassium permanganate, tobacco powder, gypsum powder, ground phosphate rock and a proper amount of water. By adding elements such as phosphorus, calcium, zinc, etc., crops can fully grow in the seedling stage, resistance to diseases and pests is increased, and use amounts of fertilizers and pesticides in the later period are reduced. Due to use of pesticides, residual pesticides will be left in crops, thus greatly threatening the health of human body. After disease-resistant active components are dissolved, modified rice hull carbonized particles are used for adsorption. The fertilizer for seedling stage has a prevention effect for a long time and is used for reducing use of pesticides.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a disease-resistant fertilizer for strong seedlings at the seedling stage and a preparation method thereof. Background technique [0002] With the development of the economy, the use of chemical fertilizers in agriculture is increasing. However, the utilization rate of crops to chemical fertilizers is low, the utilization rate of N fertilizer is 30-35%, and the utilization rate of P fertilizer is 10-20%, which will inevitably cause environmental pollution of chemical fertilizers. The problems of soil structure destruction and soil fertility decline, as well as water eutrophication are irreversible. [0003] Silicon is one of the important elements necessary for the growth and development of crops. People are paying more and more attention to the research of silicon. The introduction of research has confirmed that silicon can enhance the stems of crops, resist lod...
