Common andrographis herb and corn interplanting method

Abstract

The invention discloses a common andrographis herb and corn interplanting method, and the method comprises the following steps: (1), selecting common andrographis herb seeds, enabling the seeds to be soaked under the temperature from 35 DEG C to 45 DEG C for 18-24 hours, and carrying out the breeding of the seeds to 12-17 cm, wherein the thousand seed weight is 0.95 g or more; (2), making rectangular pieces of land in a field, wherein the width is set as 1.0-1.4 m and the height is set as 13-18 cm; carrying out the dibbling of corn at two sides of each rectangular piece of land, wherein 2-3 seeds are placed in each hole, and the plant spacing is 25-30cm; (3), transplanting the seedlings of common andrographis herb at step (1) to the centers of rectangular pieces of land, wherein 2-3 seedlings are planted in each hole, and the plant spacing is 20-25 cm; carrying out watering of root fixing water at a time; (4), carrying out the interplanting of common andrographis herb and corn at step (3), carrying out the field management, and cutting the parts, above the ground, of the common andrographis herb when the common andrographis herb grows to 4-6 cm high from the ground. The method employs the interplanting of common andrographis herb and corn, and gives play to the growth space and time advantages of high-stalk corn and low-stalk common andrographis herb. The high-stalk corn gives play to the advantages of early sowing shading when the common andrographis herb is in a growing period, thereby effectively reducing the illumination intensity after the common andrographis herb is transplanted, preventing the sunlight from damaging the common andrographis herb, and prompting the growth of common andrographis herb.

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 flowering period from August to September and fruiting period in 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 en...

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
