Special liquid composite fertilizer for watermelon

Abstract

The invention relates to the field of fertilizer, especially to a special liquid composite fertilizer for watermelon. The special liquid composite fertilizer for watermelon is prepared from the following raw materials by weight: 30 to 40 parts of urea, 22 to 31 parts of ammonium nitrate, 23 to 27 parts of monoammonium phosphate, 20 to 25 parts of calcium superphosphate, 16 to 25 parts of ammonium biphosphate, 11 to 13 parts of ammonium bicarbonate, 7 to 15 parts of polyacrylamide, 7 to 12 parts of potassium sulfate, 7 to 11 parts of copper sulphate and 70 to 130 parts of deionized water. The special liquid composite fertilizer has balanced and comprehensive nutrients and high absorptivity, reduces waste of the fertilizer and can improve the quality and output of watermelon.

Description

technical field [0001] The invention relates to the field of chemical fertilizers, in particular to a special liquid compound fertilizer for watermelons. Background technique [0002] Watermelon is a kind of fruit that people like very much every day. Watermelons require less fertilizer in the early stage, more in the middle and late stages, and less in the late stage. At present, watermelon fertilization is mostly based on a single fertilizer. Although it has a positive effect on the yield, it has a certain impact on the quality of the fruit. In farmland fertilization, the dissolution of granular chemical fertilizers requires a lot of water. Sometimes due to lack of water and other reasons, the dissolution time of granular chemical fertilizers is too long, which will affect the growth and development of crops. Liquid compound fertilizers have advantages over solid compound fertilizers in mechanical fertilization because their various nutrients are evenly dissolved in wate...
