Preparation method of organic watermelon continuous cropping high-yield composite bacterial fertilizer

Abstract

The invention discloses a preparation method of an organic watermelon continuous cropping high-yield composite bacterial fertilizer, relating to the organic watermelon continuous cropping high-yield cultivation technology. The raw materials include turf, biogas residue, plant ash, enzyme microorganism, boron-magnesium fertilizer, zinc sulfate, ammonium molybdate, hydnocarpus anthelmintica, pomegranate root peel, tripterygium wilfordii, ningnanmycin, bacillus subtilis, verticillium chlamydosporium and choline chloride. The method disclosed by the invention has the beneficial effects that through the synergistic effect of the raw materials, the problems of serious watermelon growth obstacle such as nutrient (especially organic matters, trace elements and the like) lack and imbalance, frequent occurrence of pest and disease damage and germ damage, drop of quality and output and the like caused by continuous cropping of watermelons can be fundamentally solved. Meanwhile, by adopting multiple beneficial bactericides and Chinese herbal medicine organic insecticides instead of high-toxicity high-persistent pesticides, the harm to physical health and environment is avoided and reduced, and organic watermelons which are really green and pollution-free and have pure taste and high sweetness are produced. By adopting the scientific formula, the continuous cropping diseases of watermelons can be effectively treated, and high quality and high output still can be obtained through continuous cropping of watermelons.

Description

Technical field: [0001] The invention relates to watermelon cultivation technology, mainly relates to organic watermelon continuous cropping high-yield cultivation technology, in particular to organic watermelon continuous cropping high-yield compound bacterial fertilizer and a preparation method thereof. Background technique: [0002] Due to the lack of arable land, it is difficult to replant watermelon. The most feared crop is watermelon, but now nearly 80% of the melon land is replanted every year. Due to the selective absorption of nutrients by crops in continuous cropping, the supply of soil nutrients is unbalanced and lacking, and most farmers only know to use a large amount of nitrogen, phosphorus, and potassium, but do not know how to supplement the use of medium and trace elements according to the nutritional requirements of watermelon crops. elements, organic matter and cellulose. Due to repeated and large-scale use of a limited number of commonly used chemical fe...

AI Technical Summary

Problems solved by technology

Due to the selective absorption of nutrients by crops in continuous cropping, the supply of soil nutrients is unbalanced and lacking, and most farmers only know to use a large amount of nitrogen, phosphorus, and potassium, but do not know how to supplement the use of medium and trace elements according to the nutritional requirements of watermelon crops. Elements, Organic Matter and Cellulose

Due to repeated and large-scale use of a limited number of commonly used chemical fertilizers year after year, the soil aggregate structure is destroyed, and the soil physical environment is destroyed; the soil nutrient imbalance caused by continuous cropping leads to the decline of crop resistance to diseases and insect pests, and the increase and aggravation of diseases, insect pests and pathogens in the soil. In this regard, most farmers only know to use
