The invention provides a soil bio-activator for ginseng continuous cropping and belongs to the field of modernization of Chinese traditional medicine. The soil bio-activator for ginseng continuous cropping can be used for solving the problems of serious ginseng continuous cropping diseases, low yield and poor quality caused by deterioration of the physicochemical and biological characters of old ginseng-grown land soil. The soil bio-activator for ginseng continuous cropping is prepared from 2.0%-8.0% of bacillus subtilis, 2.0%-8.0% of actinomycetes, 5.0%-20.0% of xylanase, 5.0%-20.0% of cellulase, 10.0%-20.0% of urease, 1.0%-4.0% of potassium dihydrogen phosphate, 0.1%-0.5% of ferrous sulfate, 0.1%-0.4% of boric acid, 0.1%-0.5% of manganese sulfate, 0.05%-0.2% of copper sulfate, 0.1%-0.4% of zinc sulfate, 0.05%-0.2% of ammonium molybdate and the balance of organic materials through mixing and compositing. The soil bio-activator for ginseng continuous cropping is used for improving the soil for ginseng continuous cropping in ginseng growing.

The invention discloses a stereo-planting method of strawberries and grapes in a multi-span greenhouse. The stereo-planting method comprises the following steps: 1, planting grapes, namely setting a grape line spacing to be 2-2.5m and a grape row spacing to be 1.8-2m; performing culturing by adopting a single-pole umbrella shaped mode, keeping the height of grape main stems to be 1.8-2m, selectingone main stem in the same year of planting, performing vertical leading and binding, and setting the pole height to be 1.8-2m; and 2, planting strawberries, namely taking the grape main stem as a center, building a strawberry culture frame with a height of 60-80cm with angle iron and square tubes or woods and bamboo, fixing PVC strawberry planting tanks on two sides of the frame, arranging deflectors and filter membranes under the PVC strawberry planting tanks, setting the length of the planting tanks according to the span of the greenhouse, and putting planting substrates in a proportion ofpeat to perlite to vermiculite to mushroom residues being 2:1:1:1 in the planting tanks. According to the stereo-planting method, strawberries are planted in a grape dormant period to save lands and effectively reduce the soil continuous cropping obstacle of strawberries, reduce diseases and insect pest and increase the planting benefit of the unit area.

The invention relates to a specific fertilizer for radix millettiae speciosae. The specific fertilizer is prepared by mixing the following raw materials in percentage by weight: 18-25% of a compound fertilizer, 12-18% of ammonium chloride, 8-12% of monoammonium phosphate, 6-10% of calcium superphosphate, 35-40% of potassium chloride, 10-12% of sodium humate, 5-8% of an anti-continuous-cropping soil conditioner and 1-3% of a pH buffering agent. According to the invention, nutrients are proportioned according to the demands of radix millettiae speciosae, so that the utilization rate of the nutrients is high, the disease resistance is enhanced, and the production increasing of radix millettiae speciosae is promoted.
