Andrographis paniculata high-quality and high-yield planting method

Abstract

The present invention discloses an andrographis paniculata high-quality and high-yield planting method. The andrographis paniculata high-quality and high-yield planting method comprises the followingsteps: S1, conducting seedling selection: obtaining mother branches; S2, conducting cutting: cutting the mother branches on a planting sponge and also conducting placing in a seedling culturing tray with a nutrient solution; S3, conducting root promotion: placing the cutting mother braches in the seedling culturing tray in an environment of 20-28 DEG C and a humidity of 55-75% for root promotion,conducting culture in a dark environment in first 1-2 days, and then conducting light culture in a combination of red and blue light; S4, transplanting seedlings and conducting cultivating: transplanting the mother branches to a nutrient solution-containing growing water tank for cultivation; S5, enriching buds: after cultivating ending in the S4, removing heads of plants, and conducting light culture to enable new buds to grow from base parts of blades of andrographis paniculata without top buds; and S6, conducting harvesting. The andrographis paniculata high-quality and high-yield planting method has advantages of low andrographis paniculata planting disease rate, 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
