Embodiment Construction

[0051] 1. The preparation method of soil bio-improvement agent for old ginseng land: by weight percentage, take soybean cake 0.5%~1.5%, cornmeal 1.0%~2.0%, brown sugar 0.5%~1.5% and compound amino acid 0.3%~1.0%, corn stalks The rod is cut into 1cm long sections, then pulverized, the water content is adjusted to 60%, and the remainder is taken. When composting, mix soybean cake, cornmeal, brown sugar, compound amino acid and crushed corn stalks evenly, adjust the pH to 6.5-7.0, and then compost to prepare the old ginseng field soil bio-improvement agent of the present invention.

[0052] The composting process is divided into four stages according to the temperature change. The heating stage: the compost rises from normal temperature to 40-50°C; the high-temperature stage: the temperature is 50-70°C; the cooling stage: the temperature drops below 50°C; Stage: In this stage, the slow mineralization and humification process continues, and the temperature in the compost heap is s...

Abstract

The invention relates to an old ginseng land soil biological modifying agent, belonging to the field of agricultural technology. The old ginseng land soil biological modifying agent solves the problems of worsening soil condition of the old ginseng land and low ginseng cultivation yield. The old ginseng land soil biological modifying agent is prepared by composting 0.5-1.5% of soybean meal, 1.0-2.0% of maize flour, 0.5-1.5% of brown sugar, 0.3-1.0% of composite amino acid and ground plant straw, and can be used for improving the soil of the old ginseng land soil when in ginseng cultivation.

Description

Technical field: [0001] The invention belongs to the technical field of agriculture and relates to a soil bio-improving agent for old ginseng soil. Background technique: [0002] "Old ginseng land" refers to the soil where a crop of ginseng has been planted by sowing or transplanting. Since ginseng grows in the same place for many years after sowing or transplanting, the soil condition tends to deteriorate gradually. The main manifestations are: the number of soil microorganisms is reduced, the activity of soil enzymes is reduced, the physical properties of the soil are deteriorated, and the content of organic matter is reduced. The above factors make ginseng unsuitable for continuous cropping. After continuous cropping of ginseng, the appearance quality is poor (ginseng root skin is rough, browning), the disease is serious (ginseng root rot), and the yield decreases. Due to the obstacle of continuous cropping of ginseng, ginseng has been cultivated in the way of deforesta...
