Abstract:
Provided are a slow-release special fertilizer for muskmelons and a preparation method therefor. The slow-release special fertilizer for muskmelons comprises the following components in percentages 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 a nitrification inhibitor, and 1-2% of a composite bacteriostatic substance. In the present invention, the wormcast serves as the main raw material and is capable of supplying organic nutrients for crops, and meanwhile, the Bacillus megaterium and the wormcast can achieve a synergistic effect, such that the yield of muskmelons is increased, and the quality of the muskmelons is improved. The slow-release special fertilizer is prepared according to the nutrient rule required for the growth of the muskmelons and the optimal proportion of ammonium nitrate, can be used as a base fertilizer to be applied in one dose, does not need topdressing in the later period, and is capable of decreasing the fertilizer release rate, such that the wasting of the fertilizer is avoided, and the fertilizer utilization rate is increased. In addition, the composite bacteriostatic substance is particularly added, such that Fusarium wilt of muskmelons in the seedling stage can be effectively prevented.
