A special slow-release compound fertilizer for disease-resistant and high-yield sesame planting

Abstract

The invention relates to the field of crop compound fertilizer, and particularly relates to a special controlled-release compound fertilizer for planting disease-resistant high-yield sesame. The compound fertilizer is prepared from the following raw materials in parts by weight: 15-18 parts of waste and inferior tobacco, 12-15 parts of composted animal dung, 1-2 parts of medical stone powder, 4-5 parts of zeolite powder, 35-40 parts of urea, 0.01-0.02 part of sodium selenite, 28-30 parts of potassium chloride, 3-5 parts of zinc sulfate, 1-3 parts of sticky rice starch, 6-8 parts of sodium hydroxide, 1-3 parts of glycerin, 6-9 parts of hydroxyethyl cellulose, 10-12 parts of honeysuckle straw, 6-8 parts of bamboo shoot, 0.1-0.2 part of ant powder, 15-18 parts of monopotassium phosphate, 4-5 parts of chamaecyparis leaves, 8-10 parts of hydroxyapatite powder and 3-5 parts of auxiliaries. In the controlled-release compound fertilizer provided by the invention, the nutrients are adsorbed by the prepared adsorbent to avoid invalid loss of the nutrients; meanwhile, the controlled release effect is realized by use of an environment-friendly nontoxic coating agent, the fertilizer effect is prolonged, and the fertilizer requirement of sesame in each growth stage can be met; and the active ingredients contained in the controlled-release compound fertilizer effectively enhance the disease and bacterial resistance of the crops, improve the soil environment, promote the nutrient uptake of the crops and realize an obvious effect of increasing both yield and income.

Description

technical field [0001] The invention relates to the field of special compound fertilizer for crops, in particular to a special slow-release compound fertilizer for disease-resistant and high-yield sesame planting. Background technique [0002] Compound fertilizer plays an extremely important and indispensable role in modern agriculture. Compared with traditional organic fertilizers, it has the advantages of many types of nutrients, high content, high nutrient utilization rate, and convenient packaging, storage, and application. It is the future chemical fertilizer. direction of development. However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necess...

However, most of the existing compound fertilizers have a relatively fixed nutrient ratio, which cannot meet the growth needs of different soil environments and different crop varieties at each growth stage, and eventually lead to the ineffective loss of fertilizer efficiency, and cannot achieve a satisfactory effect of increasing production and income. Therefore, it is very It is necessary to formulate special fertilizers for different crops based on the characteristics of fertilizer requirements of different types of crops, and carry out scientific proportioning. On the basis of not destroying the soil balance, it can prolong the duration of fertilizer effect, improve soil vitality, promote the growth of crop roots, and increase root resistance. Nutrient absorption efficiency, avoiding invalid release of fertilizer effect, so as to achieve the purpose of improving planting efficiency, and realize sustainable green planting, and provide consumers with high-quality products
