Special watermelon fertilizer and preparation method thereof

Abstract

The present invention discloses a special watermelon fertilizer and a preparation method thereof, wherein the raw materials comprise, by weight, 44-46 parts of urea, 23-25 parts of potassium sulfate, 12-15 parts of bone glue residue, 20-25 parts of rotten Chinese cabbage, 20-25 parts of calcium-magnesium-phosphorus fertilizer, 8-10 parts of wheat germ powder, 2-4 parts of honeycomb, 3-5 parts of castor root, 2-4 parts of sophora flavescens, 1-3 parts of Dendranthema indicum, 2-4 parts of potassium ore powder, 3-5 parts of sweet potato powder, 8-9 parts of pumpkin stem, 2-4 parts of ginkgo leaf, 1-3 parts of Platycodon Grandiflorum flower, 0.3-0.5 part of acrylic acid, 1.0-1.5 parts of chitosan, 1.2-1.5 parts of potassium chloride, 0.7-0.8 part of calcium bicarbonate, 0.2-0.4 part of calcium lactate, 0.4-0.6 part of manganese sulfate, and 0.8-0.9 part of zinc sulfate. According to the present invention, the special watermelon fertilizer has complete nutrition and can meet nutritional requirements of watermelon growth at various stages, the nutrients are easily absorbed by watermelon through enzymolysis on the wheat germ powder, and with the fertilizer, characteristics effective watermelon quality improving, green watermelon leaf, beautiful flowers, flowering phase prolonging and yield increase are provided.

Description

[0001] technical field [0002] The invention relates to the field of manufacturing organic fertilizers, in particular to a special fertilizer for watermelons and a preparation method thereof. [0003] Background technique [0004] At present, there are many studies on watermelon fertilization technology in my country. Although most farmers have realized the significance of formula fertilization, they have not applied much to watermelon fertilizers, and topdressing inorganic nutrients rarely consider the nutritional characteristics and fertilizer absorption laws of watermelons. Phosphorus and potassium fertilizers are applied only, and the time and frequency of fertilization are not well controlled, which affects the yield and quality; at the same time, in recent years, in order to pursue the yield of watermelons, blindly excessive fertilization has occurred from time to time, which not only reduces the quality of watermelons, but also makes redundant watermelons.

[0004] At present, there are many studies on watermelon fertilization technology in my country. Although most farmers have realized the significance of formula fertilization, they have not applied much to watermelon fertilizers, and topdressing inorganic nutrients rarely consider the nutritional characteristics and fertilizer absorption laws of watermelons. Phosphorus and potassium fertilizers are applied only, and the time and frequency of fertilization are not well controlled, which affects the yield and quality; at the same time, in recent years, in order to pursue the yield of watermelons, blindly excessive fertilization has occurred from time to time, which not only reduces the quality of watermelons, but also makes redundant watermelons. Nutrients such as nitrogen and phosphorus flow into the water system, causing eutrophication of the water body and bringing certain impacts on the environment
