Method for interplanting andrographis paniculata and corn

Abstract

The invention discloses a method for interplanting andrographis paniculata and corns. The method comprises the following steps: 1, selecting to use andrographis paniculata seeds, thousand seed weight being more than 0.95 kg, soaking the seeds for 18-24 hours at the temperature of 35-45 DEG C; breeding seedlings to 12-17 cm; 2, building a bed whose width is 1.0-1.4 m and height is 13-18 cm, planting corns on two sides of the bed in a point manner, planting 2-3 seeds in each hole, row spacing being 25-30 cm; 3, transplanting andrographis paniculata seedlings in the step 1 to the center of the bed, planting 2-3 plants of seedlings in each hole, row spacing being 20-25 cm, watering root fixing water once; 4, performing interplanting on the andrographis paniculata and corns in the step 3, and performing field management, until the andrographis paniculata grows to 4-6 cm above ground, cutting the aboveground parts. The interplanting of the andrographis paniculata and corns develops advantages of high-stem corns and short-stem andrographis paniculata on growing space and time. The high-stem corns develop advantages of early sowing shading of the high-stem corns in a growing period of the andrographis paniculata, and can effectively reduce illumination intensity after the andrographis paniculata is transplanted, thereby preventing sunshine from burning the andrographis paniculata, and promoting growth of the andrographis paniculata.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to a method for interplanting andrographis paniculata and corn. Background technique [0002] Andrographis paniculata is a plant of Andrographis paniculata in the family Acanthaceae. The whole herb or leaves are used as medicine. It is a medicinal material with many clinical applications in traditional Chinese medicine, and it is also an important raw material for many Chinese patent medicines. [0003] Andrographis paniculata is a perennial or annual herb with a flowering period of August to September and a fruiting period of October. Andrographis paniculata likes a warm and humid climate and is afraid of drought. If there is no watering for a long time, the growth will be slow, the leaves will be small, and the flowers will bloom early, which will affect the yield. The optimum temperature for plant growth is 25-30°C. When the temperature is around 27°C and there is ...

AI Technical Summary

Problems solved by technology

During the growth process of Andrographis paniculata, it is afraid of drought and is not tolerant to strong light. Especially when the seedlings are exposed to strong sunlight, the leaves are easy to burn and cause poor growth, low yield and poor quality.

In production, the method of setting up sunshade nets to prevent exposure to the sun is not only time-consuming, but also requires a large investment and low economic benefits, which is not conducive to large-scale promotion
