Rhizoma paridis-fleeceflower root double-dwarf combined breeding method

Abstract

The invention provides a rhizoma paridis-fleeceflower root double-dwarf combined breeding method which is used for solving the problems in the prior art that booming, fruiting and growth of rhizoma paridis are influenced due to super-high or super-low illumination intensity and high light radiation as well as high temperature caused by lodging high stems of plants, broken fruits of pedicels and constant light transmittance of a shading net. The lodging high stems influencing the growth of plants and broken thin and long fruits of the pedicels can be removed by thickening stalks by means of spraying stalk thickening liquid and reducing the height of the plants; by building a fleeceflower root dwarf shed, and adopting a flower arrangement, flowering and branch trimming method, the light transmittance is adjusted, the growth of the plant and fruits of rhizoma paridis is promoted, the yield of fruits and seeds of the rhizoma paridis can be increased, and adverse effect on the plants and fruits due to super-high and super-low illumination intensity and high light radiation heat caused by high temperature radiated by the shading net and the constant light transmittance of the shading netcan be eliminated; according to the method, the anti-lodging rate of the rhizoma paridis reaches up to 97.6%, and the fruit setting rate of the pedicels reaches up to 89%, so that the method is beneficial to the promotion of the seed propagation and reproduction of the rhizoma paridis, and has active effects on protecting the resources of wild rhizoma paridis and meeting the medical market demands.

Description

technical field [0001] The invention relates to the field of dwarfed fruit-setting technology of Chinese herbal medicine Huazhonglou and the technical field of low shed light control of Polygonum multiflorum, in particular to a dwarfed fruit-setting method of Huazhonglou. Background technique [0002] Huachonglou, also known as Zhaxiu, Baikansui, Caoheche, Jinxianhuachonglou, Aescin, etc., belongs to the perennial herb of Liliaceae. It grows in a shaded environment and is mainly produced in Yunnan, Guizhou, Fujian and other places. It is a relatively rare Chinese herbal medicine. It is slightly cold in nature and bitter in taste. It is often used for boils and carbuncles, sore throat, poisonous snake bites, pain from falls, convulsions and convulsions. [0003] The medicinal part of Huazhonglou is in the rhizome, which has a long growth cycle and high commercial value. Therefore, vigorously developing the artificial seedling propagation technology and high-yield cultivation...

AI Technical Summary

Problems solved by technology

[0012] The current pollination and fruiting propagation technology of Huachonglou adopts high-shelf cultivation with sunshade nets, which has high production costs. The high sheds with sunshade nets are constructed with cement columns, iron wires and sunshade nets, and the sunshade nets need to be replaced once every two years, so the production cost is high.

In addition, after pollination and fruit setting of Huazhonglou, the high stem and slender fruit stalk consume a lot of plant nutrition. As the fruit of Huazhonglou grows larger, the slender fruit stalk cannot support the weight of the fruit and is broken, which seriously affects the normal growth of the fruit. , the low fruit setting rate is only 61.67%, and 30-50 seeds are fruitful. The cost of artificial breeding of Huazhonglou is greatly increased, and it has become a technical bottleneck that is difficult to promote the reproduction and reproduction of Huazhonglou seeds.
