A stable long-acting slow-release fertilizer special for watermelons and a fertilization method

Abstract

The present invention relates to the technical field of fertilizers, and in particular relates to a stable long-acting slow-release fertilizer special for watermelons and a fertilization method. The fertilizer special for watermelons comprises a nitrogen fertilizer, a phosphate fertilizer, a potash fertilizer, a microelement and a filler, wherein by weight, the nitrogen fertilizer is 36.5 parts, the phosphate fertilizer is 16.1 parts, the potash fertilizer is 40 parts, the microelement zinc fertilizer is 2.1 parts, and the filler is 5.3-12 parts; or the nitrogen fertilizer is 36.5 parts, the phosphate fertilizer is 16.1 parts, the potash fertilizer is 33.3 parts, the microelement zinc fertilizer is 2.1 parts, and the filler is 5.3-12 parts. The fertilizer of the present invention is a multielement compound fertilizer containing nitrogen, phosphate, potassium and microelement zinc, and can fundamentally solve problems of nutrient imbalances, low yields and poor quality in watermelon production. In the production of the universal compound fertilizer special for watermelons of the present invention, the NAM agent capable of delaying the releasing and conversion speed of fertilizer nutrients and extending fertilizer efficiency is added, which both improves fertilizer use efficiency, and provides great convenience for production, packaging, and application of the fertilizer, to reduce agricultural production cost and fertilizer production, supply and marketing costs.

Description

technical field [0001] The invention relates to the technical field of chemical fertilizers, in particular to a stable and long-acting slow-release watermelon special fertilizer and a fertilization method. Background technique [0002] With the development of agriculture, chemical fertilizers are becoming more and more important to crop yields, but the proportion of fertilization in production is out of balance, manifested in heavy nitrogen, phosphorus fertilizers, and light potassium fertilizers. Not only the fertilizer efficiency cannot be brought into full play, but also the growth of watermelon is affected, resulting in stagnant watermelon production, poor quality, and even deterioration of soil physical and chemical properties, polluting the environment. In addition, due to lack of labor in rural areas or due to lack of water, untimely water supply and other reasons, crop fertilization is increasingly simplified.
