A kind of high-quality and high-yield planting method of Andrographis paniculata

Abstract

The invention discloses a high-quality and high-yield planting method of Andrographis paniculata, comprising the following steps: S1, seedling breeding: obtaining mother branches; S2, cutting: cutting the mother branches on a planting sponge, and placing them on a seedling tray provided with nutrient solution Inside; S3, root promotion: put the cuttings in the seedling tray, the mother branch is placed in an environment of 20-28 ° C, and the humidity is 55-75% to promote rooting, cultivate in a dark environment for the first 1-2 days, and then cultivate in light, Illumination cultivation is carried out under the combination of red and blue light; S4, transplanting seedlings, breeding: transplanting the mother branch to a planting tank with nutrient solution for cultivation; S5, abundant buds: removing the heads of the plants after the cultivation in step S4 Light cultivation, the terminal buds that Andrographis paniculata does not have grow from the base of the leaves; S6, harvest. The invention has the advantages of low planting disease rate of andrographis paniculata, good quality and high yield.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, more specifically, it relates to a high-quality and high-yield planting method of Andrographis paniculata. Background technique [0002] Andrographis paniculata (Burm.f.) Nees, also known as spring lotus and autumn willow, happy at first sight, terminalia, bitter gall, golden herb, golden ear hook, Indian grass, bitter grass, etc. Annual herb, 4-8 cm long and 1-2.5 cm wide. Medicinal plants have the functions of clearing away heat and detoxification, reducing inflammation, reducing swelling and relieving pain. Andrographis likes high temperature and humid climate. Hi sunny, hi fat. The suitable temperature for seed germination and seedling growth period is 25-30°C. When the temperature drops to 15-20°C, the growth is slow, and the temperature drops to about 8°C, and the growth stagnates; when the temperature drops to about 0°C or frost, all the plants wither. Fertile, loose, wel...

AI Technical Summary

Problems solved by technology

[0003] Andrographis mostly adopts the planting mode of planting and harvesting in the same year. Generally, it is appropriate to sow early to prolong the growth period. During the growth process of Andrographis paniculata, it is afraid of drought and cannot tolerate strong light. Especially when the seedlings are exposed to strong light, the leaves are easy to burn and grow poorly. , the output is low, the quality is poor, and the method of setting up a sunshade net to prevent exposure to the sun in production is not only labor-intensive and time-consuming, but also requires a large investment and low economic benefits, which is not conducive to large-scale promotion
