At present, there are not many studies on slow-release special fertilizers for melons. The conventional slow-release fertilizers not only have no obvious slow-release effect, but also are not special fertilizers for melons, and are not designed for the growth and development of melons. Therefore, conventional slow-release fertilizers on the market When release fertilizers are applied to melons, there are problems such as yield and quality are not ideal

Abstract
The invention provides a special slow-release fertilizer for muskmelons and a preparation method of the special slow-release fertilizer. The special slow-release fertilizer comprises the following components by mass: 20-30% of wormcast, 2-4% of bacillus megaterium, 5-11% of urea formaldehyde, 4-8% of monoammonium phosphate, 10-20% of ammonium nitrate, 5-15% of calcium nitrate, 5-15% of potassium sulfate, 10-12% of potassium chloride, 8-12% of triple superphosphate, 5-9% of calcium magnesium phosphate, 4-6% of clay, 0.1-0.2% of nitrification inhibitor and 1-2% of composite bacteriostatic substance. The wormcast serves as a main raw material, organic nutrients can be provided for crops, meanwhile, bacillus megatherium and the wormcast can achieve a synergistic effect, the muskmelon yield isincreased, and the muskmelon quality is improved. The special slow-release fertilizer is prepared according to the nutrient rule required by melon growth and the optimal ammonium nitrate proportion, can be used as a base fertilizer to be applied at a time, does not need topdressing in the later period, and can reduce the fertilizer release rate, avoid fertilizer waste and improve the fertilizer utilization rate. In addition, the compound antibacterial substance is specially added, so that fusarium wilt of melons in the seedling stage can be effectively prevented.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special slow-release fertilizer for melons and a preparation method thereof. Background technique [0002] Melon is one of the main economic crops in my country. Its cultivation period is short, and it is rich in nutrition and has a broad market prospect. In 2016, my country's melon planting area exceeded 480,000 hectares, with an output of 15.7 million tons (China Rural Statistical Yearbook, 2017). Melon is a fertilizer-loving crop and requires more nutrients throughout the growth period. However, under the current cultivation and management conditions, the utilization rate of chemical fertilizers in my country is low, 30-60% for nitrogen fertilizers, 10-25% for phosphorus fertilizers, and 40-70% for potassium fertilizers. The loss of chemical fertilizers not only increases the cost of planting inputs for farmers, but also causes great pollution to the soil environment. ...
