A kind of bio-fertilizer for relieving continuous cropping obstacles of sand-pressed watermelon

Abstract

The invention discloses a biological fertilizer for alleviating the obstacle of sand-pressed watermelon continuous cropping. The raw materials include: poultry manure, crop straw, fermentation microbial agent, biological activated carbon, urea, ammonium sulfate, monoammonium phosphate, and potassium sulfate; the preparation method includes: Livestock manure and crushed crop stalks are evenly mixed and then sprayed with microbial agents for aerobic composting and fermentation; the fermentation products are dried and crushed, mixed with biological activated carbon, urea, ammonium sulfate, monoammonium phosphate, and potassium sulfate, and then granulated. Pressed sand biological fertilizer for continuous cropping obstacles of watermelon. Organic nutrients prepared by fermentation of poultry manure and crop stalks are mainly used. Reasonable matching of appropriate amount of inorganic fertilizers can not only provide comprehensive and reasonable nutrients for crops, but also comprehensively improve soil quality and increase soil fertility; the fertilizer effect is rapid and long-lasting, and will not cause fertilizer It can provide comprehensive and balanced nutrients to crops, greatly improving the disease resistance of crops; it can also improve the soil, increase the aggregate structure, and improve the utilization rate of fertilizers.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a biological fertilizer for alleviating the obstacles to continuous cropping of sand-pressed watermelons. Background technique [0002] Sand-pressed watermelon, as the name suggests, is a "big watermelon that grows from the cracks in the stone". Before planting sand-pressed watermelon, a layer of sand about 10-15cm thick should be laid on the ground, and then a hole should be dug on the sand to plant it. Watermelon seedlings, in this way, after the water in the soil profile reaches the soil surface through the capillary transport in the soil, since the sand does not have capillaries, the water will not transfer from the sand to the surface, which can greatly reduce the evaporation of soil water, allowing All the water in the soil is supplied to the growth and development of Yashaxi. As a unique planting mode in some areas of Ningxia Hui Autonomous Region, Yasha waterm...

AI Technical Summary

Problems solved by technology

However, since the soil surface is covered by sand and gravel, the nutrient substances in the soil will be seriously lost if the base fertilizer and topdressing fertilizer are not used in the planting process, which will cause serious continuous cropping obstacles in the long-term continuous cropping of sand-pressed watermelon

Local melon farmers often abandon their farmland, which reduces the planting area of ​​Ningxia pressed sand melons year by year, which has become the main restrictive factor in the production process of pressed sand watermelons, seriously affecting the healthy development of the local pressed sand watermelon industry
