Water-soluble starch synergistic leaf fertilizer and preparation method thereof

Abstract

The invention discloses a water-soluble starch synergistic leaf fertilizer and a preparation method thereof. The water-soluble starch synergistic leaf fertilizer is prepared from the following raw materials in parts by weight: 40-60 parts of potassium dihydrogen phosphate, 30-50 parts of ammonium sulfate, 1-2 parts of manganese sulfate, 2-3 parts of instant boron, 4-8 parts of water-soluble starch, 0.5-1 part of chitooligosaechaddes, 20-40 parts of cow dung, 10-15 parts of soybean curb residue, 5-10 parts of banana peel, 3-6 parts of paulownia sawdust, 2-4 parts of sugarcane leaves, 3-5 parts of sunflower cake, 1-3 parts of beetroot, 4-6 parts of waste molasses, 2-3 parts of wood vinegar, 1-2 parts of hawthorn leaves, 2-3 parts of pomegranate peels, 3-4 parts of chenopodium ambrosioides, 1-2 parts of pecan leather, 2-3 parts of eucalyptus robusta, 1-3 parts of tea tree flower, 2-3 parts of kiwi fruit root, 2-3 parts of xanthium and 1-2 parts of radix sophorae flavescentis. The water-soluble starch synergistic leaf fertilizer has good stability, good anti-blocking property and the effects of disease prevention, bacterium resistance, insect pest killing, insect pest expelling and the like, can be stored for a long time and is capable of reducing the occurrence rate of diseases and insect pests of crops, reducing the using amount of chemical pesticides, increasing the crop yield and improving the crop quality.

Description

technical field [0001] The invention relates to a water-soluble starch synergistic foliage fertilizer and a preparation method thereof, belonging to the technical field of fertilizers. Background technique [0002] Foliar fertilizer is a fertilizer that directly applies the nutrients required by the crop to the leaf surface for the purpose of leaf absorption. Foliar fertilizer is a type of fertilizer that applies nutrients to the surface of crop leaves and functions through the absorption of leaves. Plant leaves have upper and lower layers of epidermis, which are composed of epidermal cells. There are cuticles and wax on the outside of the cells on the surface. , can protect the mesophyll cells under the epidermis to perform photosynthesis, respiration and other functions, and not be affected by changes in external adverse conditions. There are many tiny stomata on the leaves, which perform the function of gas replacement. Although the existing foliar fertilizers can give f...

Problems solved by technology

Although the existing foliar fertilizers can give full play to their fertilizer effects and reduce soil pollution, they still have problems such as poor stability and easy caking, which affect their yield-increasing effects
