Abstract

Special fertilizer for watermelon base fertilizer as well as preparation method of special fertilizer. The invention provides a special fertilizer for watermelon base fertilizer. The special fertilizer is prepared from the following raw materials: by weight, 10-12 parts of urea, 12-15 parts of ammonium nitrate, 20-30 parts of diammonium phosphate, 3-5 parts of potassium chloride, 15-20 parts of peat soil, 3-5 parts of gelatin, 1-2 parts of ethylene diamine tetraacetic acid, 1-2 part of waste engine oil, 1-2 part of manganese sulfate, 3-5 parts of weathered coal, 1-2 parts of ammonium molybdate, 1-2 parts of ferrous sulphate and a proper amount of chlorinated paraffin. In the special fertilizer for the watermelon base fertilizer, large-amount elements, middle-amount elements and trace elements are coated with the waste engine oil. Cohesive force among the elements is increased by the gelatin, and the gelatin is beneficial to slow release and effective utilization of the large-amount elements, middle-amount elements and trace elements. Invalid release of the large-amount elements, middle-amount elements and trace elements can be decreased. The special fertilizer for the watermelon base fertilizer is beneficial to effective slow release of fertilizer efficiency and can be fully absorbed by watermelons.

Description

technical field

[0001] The invention relates to the field of agricultural fertilizers, in particular to a special fertilizer for watermelon base fertilizer and a preparation method thereof. Background technique

[0002] There are many types of fertilizers currently used for watermelon cultivation, among which the special fertilizer for watermelon mostly adopts NPK compound fertilizer available in the market, which is mainly composed of three inorganic elements N, P, and K, which can meet the growth needs of watermelon in a short time. However, long-term use will damage the soil aggregate structure, which will easily cause soil compaction and soil hardening, thereby affecting the growth of watermelons, and the promotion effect on watermelon growth is not obvious. Contents of the invention

[0003] In order to overcome the deficiencies of the prior art, the invention provides a special fertilizer for watermelon base fertilizer and a preparation method thereof. The fertiliz...
