AI Technical Summary

Technical Problem

In the process of growing watermelons in greenhouses, excessive application of chemical fertilizers leads to the deterioration of soil physical and chemical properties, a decline in watermelon product quality, and a reduction in yield.

Method used

The organic-inorganic fertilization method is adopted, which includes applying biogas slurry fertilizer, powdered organic fertilizer, bio-fertilizer and diammonium phosphate as base fertilizer before watermelon transplanting, and applying YM type, K type and N type compound microbial fertilizer and B type ternary compound fertilizer as top dressing according to the watermelon growth stage, combined with the micro-ecological regulation of functional bacteria.

Benefits of technology

Improving soil physical and chemical properties, increasing organic matter content and water and fertilizer retention capacity, enhances watermelon quality and yield, while reducing fertilizer use and avoiding soil pollution.

Abstract

The invention provides an organic-inorganic fertilization method for arched shed watermelons, and belongs to the technical field of watermelon planting.The organic-inorganic fertilization method comprises the steps that firstly, before the watermelons are transplanted, biogas slurry fertilizer, powder organic fertilizer, biological bacterial fertilizer, diammonium phosphate and A-type ternary compound fertilizer are sequentially applied, and then base fertilizer is formed; after the watermelons are transplanted, topdressing is conducted according to the growth stage of the watermelons, and in the vine extending stage, YM type compound microbial fertilizer and B type ternary compound fertilizer are sequentially applied to promote vine growth and expand the leaf area; in the young fruit stage, a YM type compound microbial fertilizer, a K type compound microbial fertilizer and a B type ternary compound fertilizer are sequentially applied, the root system absorption efficiency is enhanced, and sugar transportation is promoted; in the fruit swelling period, a YM type compound microbial fertilizer, an N type compound microbial fertilizer and a B type ternary compound fertilizer are sequentially applied to delay leaf senescence and guarantee continuous photosynthesis of leaves; wherein the YM type compound microbial fertilizer, the K type compound microbial fertilizer and the N type compound microbial fertilizer are biogas slurry fertilizers added with functional bacteria.
