Special-purpose controlled-release compound fertilizer for plating peanuts in dry land

Abstract

The invention relates to the field of crop compound fertilizers and specifically relates to a special-purpose controlled-release compound fertilizer for planting peanuts in dry land. The compound fertilizer is prepared from the following materials in parts by weight: 30-35 parts of organic fertilizer, 20-23 parts of urea, 15-18 parts of monoammonium phosphate, 8-10 parts of castor bean meal, 12-15 parts of wheat bran, 3-5 parts of leaves of asparagus lettuce, 0.1-0.2 part of liquid paraffin, 6-8 parts of sodium alginate, 3-5 parts of methyl cellulose, 1-2 parts of sodium tripolyphosphate, 4-5 parts of cinnamomum longepaniculatum leaf residue, 4-5 parts of eggshells, 1-2 parts of capsicin, 0.1-0.2 part of disodium adenosine triphosphate, 4-6 parts of waste bittern, 1-3 parts of sodium diacetate, 0.5-1 part of tween 80, 0.2-0.3 part of nisin and 3-5 parts of auxiliaries. According to the controlled-release compound fertilizer disclosed by the invention, an active adsorbent prepared by utilizing the materials such as wheat bran, eggshells and the like, organic matter fermentation liquor rich in active ingredient, auxiliaries, and the like are mixed to prevent nutrients from invalid loss; meanwhile, a film coating agent is utilized to realize controlled release of fertility to satisfy fertility needs of crops at each growth stage, so that yield and quality of the crops are improved; moreover, a soil environment is not damaged after long-term use of the compound fertilizer.

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 dryland peanut 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 necessary to formulate special ...

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
