Special chemical fertilizer for dragon fruit and preparation method thereof

Abstract

The invention discloses a special chemical fertilizer for dragon fruit and a preparation method thereof. The special chemical fertilizer is prepared from the following components in parts by mass: 25-27 parts of nitrogen fertilizer, 21-23 parts of phosphatic fertilizer, 22-26 parts of potash fertilizer, 19-21 parts of carnallite powder, 16-18 parts of calcium superphosphate, 15-18 parts of vicia villosa green manure, 13-15 parts of ash-grass fertilizer, 12-14 parts of magnesium sulfate, 10-13 parts of microbial growth regulator, 9-12 parts of sodium molybdate, 7-9 parts of thoroughly decomposed pig manure, 5-9 parts of rice hush ash, 1-3 parts of imidacloprid, 2-3 parts of streptomycin and 30-40 parts of water. The special chemical fertilizer for dragon fruit contains an organic fertilizer, and is long in fertilizer efficiency and sufficient in delayed effect; the special chemical fertilizer is capable of providing various necessary nutritive substances for the growth of the dragon fruit, promoting the sugar accumulation of the fruits, optimizing the quality of the fruits, preventing the root of the dragon fruit trees from being bitten by insect pests and guaranteeing healthy growth of the trees.

Description

technical field [0001] The invention relates to a special chemical fertilizer for fruit, in particular to a special chemical fertilizer for dragon fruit and a preparation method thereof. Background technique [0002] Dragon fruit is a tropical and subtropical plant. The fruit is rich in nutrition and has therapeutic and health functions. It has remarkable effects on preventing constipation, lowering blood sugar and blood lipids, etc. [0003] At present, most of the dragon fruits sold in the market are imported from Vietnam. They are red-skinned and white-fleshed fruits. Because of their low sugar content, their taste is slightly inferior. [0004] Due to the long harvest period of dragon fruit, organic fertilizers should be reapplied, nitrogen, phosphorus, and potassium compound fertilizers should be applied in a balanced and long-term manner, and potassium and magnesium fertilizers should be applied during the flowering and fruiting period to promote the accumulation of fr...
