Slow release fertilizer special for fruit trees and preparation method thereof

Abstract

The invention relates to a slow release fertilizer special for fruit trees and a preparation method thereof and belongs to the technical field of the fertilizer. The technical problem to be solved is to provide the slow release fertilizer special for fruit trees. The technical scheme adopted for solving the technical problem is as follows: the slow release fertilizer special for fruit trees is composed of an inorganic core material and an organic packaging material; the inorganic core material comprises the following components in parts by weight: 20-30 parts of ammonium bicarbonate, 10-15 parts of urea, 10-15 parts of calcium oxide, 10-15 parts of monopotassium phosphate, 3-5 parts of magnesium sulfate, 3-5 parts of zinc sulfate and 3-5 parts of manganese sulfate; the organic packaging material comprises the following components in parts by weight: 30-40 parts of animal dung, 5-8 parts of buddleia, 3-5 parts of wintergreen oil, 3-5 parts of shrimp shell powder, 3-5 parts of fishbone dust, 3-7 parts of waste bacteria stick, 4-7 parts of ultrafine coal ash, 4-7 parts of sodium polyaspartate, 3-5 parts of glycine, 3-5 parts of cysteine, 3-5 parts of nicotinamide and 0.05-0.2 part of yeast. The slow release fertilizer special for fruit trees provided by the invention can obviously increase the sugar content and can improve the crop quality. The slow release fertilizer special for fruit trees can be widely applied to the field of the fruit tree fertilizer.

Description

Technical field [0001] The invention provides a special slow-release fertilizer for fruit trees and a preparation method thereof, and belongs to the technical field of fertilizer preparation. Background technique [0002] With the continuous improvement of people's living standards, people's pursuit of their own health is also increasing, and fruits have become an indispensable substance in people's daily lives. Fruit has many benefits, such as lowering blood pressure, slowing down aging, losing weight, skin care, improving eyesight, anti-cancer, lowering cholesterol, and supplementing vitamins. In most places where fruit trees grow, the climatic environment is not the same, and the soil difference is also large. Therefore, when the fruit trees are cultivated and fruited, a certain amount of fertilizer needs to be applied to them to ensure that the cultivated fruit trees have a higher survival rate. The use of fertilizers directly affects the quality of fruit trees and orchards,...

Problems solved by technology

If the farmer ignores the application of organic fertilizer and applies nitrogen fertilizer in order to pursue the yield, the nitrogen content in the fruit will be changed, and the ratio of nitrogen and calcium will increase, which will cause apple bitter pit

Moreover, the extensive use of chemical fertilizers does not meet people's pursuit of a healthy life.

On the other hand, the simple application of organic fertilizer also has the disadvantages of poor water and fertilizer retention and low survival rate.
