Problems solved by technology

Most of the existing watermelon planting fertilizers are chemical fertilizers, which have a low absorption and utilization rate, which is easy to cause waste, and long-term application will easily lead to an increase in the content of inorganic matter in the soil, weakening of organic matter, and imbalance of trace elements, resulting in slow growth of watermelon. low yield, poor taste

Abstract

The invention discloses a special watermelon fertilizer which comprises, by weight, 40-60 parts of decomposed manure, 15-25 parts of fertilizer cakes, 10-20 parts of urea, 12-18 parts of calcium superphosphate, 12-18 parts of potassium sulfate, 12-18 parts of monopotassium phosphate, 20-30 parts of coal ash, 8-15 parts of chitin and 2-4 adhesives. The special watermelon fertilizer is prepared by mixing the decomposed manure with chemical fertilizer, solves the problem of low absorption and utilization rate of a pure chemical fertilizer, has good soil restoration capacity, forms a soil microorganism ecological system, is wide in application prospect, and can provide all nutrients needed by watermelon growth when being used for watermelon planting. The growth rate of watermelons is effectively increased, and watermelon yield, quality and taste are obviously improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for watermelons and a preparation method thereof. Background technique [0002] Watermelon (scientific name: Citrulluslanatus, English: Watermelon), belongs to Cucurbitaceae, native to Africa. Watermelon is a dicotyledonous flowering plant shaped like a vine with feathery leaves. The fruit it bears is gourd, which is a kind of fleshy fruit unique to Cucurbitaceae melons. It is a false fruit developed from the lower ovary of three carpels with parietal placenta. The main edible part of watermelon is the well-developed placenta. The outer skin of the fruit is smooth, green or yellow with patterns, and the juicy flesh is red or yellow (rarely white). It can be cultivated all over the country. In the south, Hainan Island is the main production area. Due to its unique climate characteristics, watermelons are abundant all year round with various varieties. ...
