Fertilizer specialized for watermelon plantation

Abstract

The invention discloses a fertilizer specialized for watermelon plantation. The fertilizer comprises, by weight, 30-50 parts of crop straw, 10-20 parts of stevia, 10-20 parts of vegetable and fruit waste, 20-30 parts of animal manure, 20-30 parts of soybean meal, 4-12 parts of microbial fermentation agent, 10-20 parts of chalk, 2-10 parts of choline chloride, 10-20 parts of calcium superphosphate, 6-16 parts of boron fertilizer, 10-20 parts of urea, 10-20 parts of bone powder, and 8-20 parts of ammonium nitrate. The fertilizer can improve the soil, and preserve the fertility and the moisture. The fertilizer has the advantage of having high use rate and more comprehensive nutrition, having longer fertilizing effect, being capable of promoting the watermelon growth and greatly enhancing the watermelon yield, being capable of improving the watermelon quality. The fertilizer not only satisfies the nutrition needed by the fruit growth, but also alleviates the pollution and destruction to the soil caused by long term fertilizing. The harvests acquired through the use of the fertilizer are both green and safe.

Problems solved by technology

At present, watermelons are planted with chemical fertilizers for a long time. The watermelons absorb less nutrients from the fertilizers, the utilization rate of fertilizers is low, and the yield is too low. Moreover, the quality of the soil environment deteriorates, a large amount of minerals in the soil are lost, and the water quality in some areas becomes eutrophic. , at the same time, the taste of the watermelon planted is not very good
