Problems solved by technology

[0003] In the past ten years, due to the application of facility cultivation technology in watermelon production, the growing season of watermelon has been shortened and the supply cycle has been greatly extended. However, facility cultivation of watermelon has significantly increased production costs. 3,000 yuan / mu, under the premise of no sales price guarantee, melon farmers can only pursue high yield
At the same time, in order to reduce costs and pursue high yields, melon farmers basically do not apply organic fertilizers in production, but use a large amount of chemical fertilizers alone, resulting in a decline in the quality of watermelon products in my country year by year. Soil aggregate structure and ecological balance pose a huge threat to the sustainable development of watermelon production

Abstract

The invention provides a special organic fertilizer for watermelons, a preparation method and an application thereof. The preparation method comprises the following steps: (1) collecting raw materials such as roots, stems, leaves and pod peels of different varieties of soya beans, mixing the raw materials, and coarsely crushing the raw materials by using a cutting machine; (2) spraying urea with the concentration of 1% for fully wetting the crushed raw materials; and (3) stacking the crushed and wetted raw materials in a cement pool or a cement yard, covering and sealing the raw materials with a plastic film, and fermenting the raw materials. The prepared organic fertilizer can effectively meet the balance requirements of watermelons on various available nutrients in the whole growth and development stage, particularly on phosphorus and potassium elements, amino acids and trace elements, under the condition of sufficient application amount, healthy and balanced growth of plants can be promoted, the fruit setting rate can be increased, and particularly, the taste quality of watermelon pulp can be remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of organic fertilizers for crops, and in particular relates to a special organic fertilizer for watermelon and its preparation method and application. Background technique [0002] Watermelon is an important economic crop in my country, with an annual cultivation area of ​​more than 25 million mu. The cultivation and production of watermelon has become an efficient horticultural crop for farmers in many areas of my country to get rid of poverty and become rich. [0003] In the past ten years, due to the application of facility cultivation technology in watermelon production, the growing season of watermelon has been shortened and the supply cycle has been greatly extended. However, facility cultivation of watermelon has significantly increased production costs. 3,000 yuan / mu, without a sales price guarantee, melon farmers can only pursue high yields. At the same time, in order to reduce costs and pursue hig...
