Problems solved by technology

Especially in recent years, with the reduction of wild resources of sealwort and the increase of market demand, the area of ​​domestic species has become larger and larger. In order to control pests and increase production, some domestic species of sealwort have used a large amount of pesticides, rhizome expanders and even various hormones. Foliage fertilizer not only increases the cost of planting, but also the quality of sealwort fails to meet the medicinal requirements

Embodiment 1

[0024] Embodiment 1: a kind of Polygonatum polyflora rice husk covering planting method, the method comprises the following steps:

[0025] 1) Site selection: choose convenient traffic conditions, the best production site is sandy loam soil, and the soil pH value is 5-7.5;

[0026] 2) Soil preparation: remove residual branches, fallen leaves, stones and weeds on the surface of the ground, apply 1500kg-2000kg of decomposed sheep manure and 50kg of superphosphate per mu of land, and then deep plow 25-35cm to level the ground , Thinning, and then disinfect the soil with lime, and finally make a flat or high furrow, with a width of 1.1-1.2m, a height of about 20cm, and a distance of about 30cm.

[0027] 3) Seed selection and planting: Use rhizomes for propagation. Around early October or late March, dig out the rhizomes, select the young and tender parts of the apex, and cut them into several sections. Each section has 2 to 3 nodes. 8 ~ 12cm, planted in the furrow where the ditch...

Embodiment 2

[0036] It is basically the same as Example 1, except that the thickness of covering rice husk is changed to 2cm, and the effects of weed control and pest control and soil compaction are observed.

[0037]It has been observed that when the thickness of the rice husk cover layer is reduced to 2cm, there will be about 1 weed per square meter, and about 0.4 plants per square meter when the rice husk cover layer is 5cm thick, and the amount of weeds has more than doubled; the pest situation is basically the same , five samples were sampled for each spot, and no pests were found; according to the observation records of the soil moisture within one month after the rain, the rice husk cover was reduced to 2cm in the first 5 days, and the average moisture content of the plot was 30%, which was slightly higher than that of rice husk. Thickness is the plot (average water content is 25%) of 5cm, and middle 10 days time humidity is basically equal (both 20%), after 15 days, 2cm thickness ri...

Embodiment 3

[0039] It is basically the same as Example 1, except that the rice husk is not covered, and weeds, insect damage and soil compaction are observed. After observation, the plots that were not covered with rice husks had a large amount of weeds, and the number of seedlings emerged was about 4.1 per square meter. In terms of insect pests, five sampling plots were randomly checked. No pests were found in the plots covered with rice husks, but found 2 insect eggs; soil conditions According to the observation records within one month after the rain, except for the first 3 days, the soil humidity of the plots not covered with rice husks was slightly higher than that of the plots covered with rice husks. As time went on, the humidity of the former was gradually lower than that of the latter The former, especially after ten days, the difference increases sharply with time, which shows that the former is lower than the latter in terms of moisture retention and waterlogging prevention capa...

Abstract

The invention discloses a method for planting polygonatum cyrtonema. The method comprises the steps of site selection, land preparation, seed selection and planting, weeding, topdressing, timely irrigation and drainage, bud removal, disease and pest control and harvesting. According to the method, rice husk is adopted for coverage to preserve heat and moisture, the conditions of soil watering hardening are effectively avoided, the good breathability of soil is maintained, and the respiration effect of plant rhizomes is promoted. Due to the isolation effect of the rice husk, worm eggs and grass seeds can be effectively prevented from entering soil of the earth's surface, the investment on pest and disease control and intertillage weeding is reduced, pesticide residue is avoided, the green and pollution-free production is achieved, and the quality of polygonatum cyrtonema is guaranteed. According to the method, after the harvesting of polygonatum, the rice husk can be subject to steam sterilization and then be subject to waterlogged compost to serve as base fertilizer, not only can further improve soil structure, but also can reduce invested cost.

Description

technical field [0001] The invention relates to a method for planting Chinese herbal medicines, in particular to a method for planting Polygonatum polyflora covered with rice husks. Background technique [0002] Polygonatum cyrtonema is used as medicine with rhizomes, sweet and flat. Tonify qi and nourish yin, invigorate the spleen, moisten the lungs, and benefit the kidneys. For weakness of the spleen and stomach, fatigue and fatigue, dry mouth and lack of food, dry cough due to lung deficiency, insufficient essence and blood, internal heat and thirst. Distributed in Anhui, Henan, Yunnan, Guizhou, Hubei, Jiangsu, Jiangxi, Sichuan, Hunan and other places in mainland China. [0003] Polygonatum has been planted in my country for more than 2,000 years. The wild species of Polygonatum began to be studied by a small number of people around 2003. In recent years, certain results have been achieved. Some varieties have formed relatively mature cultivation methods. However, ther...
