Planting method for improving yield of pseudo-ginseng

Abstract

The invention discloses a planting method for improving the yield of pseudo-ginseng. A planting area where the rainfall is sufficient, the height of each layer of the earth surface has plant distribution, the cloud and mist wind around, the air flow is good, the temperature change and the humidity change are stable, the temperature in winter is low, and the temperature of the spring rises late is selected; the pseudo-ginseng is planted in the mountain slope with the altitude of 1000-2000m or above and the gradient of 5-25 degrees. A sunshade net shed is set, the land is ploughed, a ridged field is made, a base fertilizer is spread on the surface of the ridged field; seeds of excellent pseudo-ginseng population with strong cold resistance and strong disease resistance are selected and treated by salicylic acid and warm water, and then the treated seeds are sowed to naturally germinate to form seedlings, and one year later the pseudo-ginseng is dug, dried in the sun, and preserved. The growth environment of the pseudo-ginseng is better, and diseases and pests are reduced, the harmful substances in the soil are less, the sprouting is promoted, the seedlings are stronger and healthy; the diseases and pests in the growth process of the pseudo-ginseng are reduced, and the proper base fertilizer is adopted to facilitate providing of the nutrients, the water-retaining, heat-preserving, breathable and fertilizer-retaining capabilities of the soil are increased, and the yield of the pseudo-ginseng is improved.

Problems solved by technology

The origin of artificially cultivated Panax notoginseng has not yet been solved due to the continuous cropping technology, and the land that has been planted with Panax notoginseng can no longer be reused, resulting in less and less suitable land for planting Panax notoginseng in the old producing areas, and it is difficult to plant notoginseng on a large scale. The development of the planting industry and the entire industry has shifted the planting area of ​​Sanqi to high-altitude areas. The existing methods of planting Panax notoginseng in high-altitude areas have the problems of low emergence rate and low yield
