Abstract

The invention discloses a special coated compound fertilizer for Chinese chestnuts. The special coated compound fertilizer is characterized by being prepared from the following raw materials in parts by weight: 89-100 parts of castor seed oil cakes, 25-34 parts of sawdust, 18-24 parts of wood fiber, 28-33 parts of monoammonium phosphate, 33-40 parts of potassium chloride, 2-3 parts of magnesium sulfate, 1-2 parts of humic acid chelated manganum, 9-12 parts of nanometer bentonite, 8-11 parts of potassium of polyaspartic acid, 26-32 parts of urea, 30-36 parts of sewer mud, 28-34 parts of turfy soil, 5-7 parts of EM (Effective Microorganism) agent, 8-10 parts of soil conditioner and a proper amount of water. According to the invention, the fertilizer with a slow release effect can be prepared by fermenting organic matters, mixing the fermented organic matters and a chemical fertilizer and coating through melting by using urea; due to the addition of the soil conditioner, the special coated compound fertilizer has the effects of increasing the efficiency, promoting plants to absorb nutrients and slowing releasing; the prepared fertilizer can be used for improving the soil condition, has the characteristics of water and fertilizer retention and slow fertility loss, and can also be used for ensuring that chestnuts are robust in growth and stable in high yield.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a special compound coated fertilizer for chestnuts and a preparation method thereof. Background technique [0002] Chestnut is a perennial fruiting tree, and the harvest of fruit every year will take away a large amount of nutrients. If it is not supplemented in time, it will inevitably affect the tree vigor and cause serious big and small years. Reasonable fertilization is one of the important measures to promote tree health, enhance resistance and prolong fruit life, and obtain high and stable yield. According to the characteristics of the nutritional needs of chestnut trees, a reasonable ratio of nitrogen, phosphorus, and potassium and phased application should be achieved in fertilization, while supplementing the necessary medium and trace mineral nutrients for chestnut trees. The base fertilizer is generally applied in combination with deep plowing to improve the soil after fruit...
