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 fertilizer for slow-release of melon and a preparation method thereof. The special fertilizer for slow-release of melon includes the following components: 20-30% of vermicompost, 2-4% of Bacillus megaterium and 5% of urea formaldehyde in terms of mass percentage. ‑11%, Monoammonium Phosphate 4‑8%, Ammonium Nitrate 10‑20%, Calcium Nitrate 5‑15%, Potassium Sulfate 5‑15%, Potassium Chloride 10‑12%, Superphosphate 8‑12%, Calcium magnesium phosphate fertilizer 5-9%, clay 4-6%, nitrification inhibitor 0.1-0.2%, compound antibacterial compound 1-2%. The present invention uses vermicompost as the main raw material, which can provide organic nutrients for crops, and at the same time, Bacillus megaterium can synergize with the vermicompost to increase the yield of melon and improve the quality of melon. The slow-release special fertilizer of the present invention is prepared according to the nutrient law required for the growth of melon and the most suitable ratio of ammonium nitrate, and can be applied as a base fertilizer at one time, without topdressing in the later stage, and the slow-release special fertilizer of the present invention can reduce the fertilizer release rate and avoid fertilizer waste. , improve fertilizer utilization. In addition, the present invention specially adds compound bacteriostatic substances, which can effectively prevent the occurrence of fusarium wilt at the seedling stage of melon.
Description
technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special fertilizer for melon slow-release and a preparation method thereof. Background technique [0002] Melon is one of the main economic crops in my country. It has a short cultivation period, is rich in nutrients 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 fertile crop and needs more nutrients throughout the growth period. However, under the current cultivation and management conditions, the utilization rate of chemical fertilizers in my country is relatively low, with nitrogen fertilizer being 30-60%, phosphorus fertilizer being 10-25%, and potash fertilizer being 40-70%. The loss of chemical fertilizers not only increases the cost of farmers' planting inputs, but also causes great pollution to the soil environment. [00...
