6 Ways To Promote Medicinal Plants Yield

July 12, 2021

First, The correct lighting environment

Light is the basic food for plants. Converting light into energy through photosynthesis is the way plants get all the energy to grow and bloom. One of the most important things to do after you sprout your seeds is to make sure your plants get enough light.

Light intensity medicinal crops require at least 3000 lumens per square foot. For maximum productivity, 7000 to 10,000 lumens per square foot (1300-1800umol/m2/s) is available.

Light quality has an impact on plant growth, morphogenesis, photosynthesis, material metabolism and gene expression. Among the visible light (380-780 nm) absorbed by plants, red light and blue light are the main sources of photosynthesis absorption in plants, and the ratio of red and blue light is important for the growth regulation of medicinal plants.

Medicinal plants is a light-light, short-day plant. Suitable photoperiod regulation is conducive to early flowering of plants.

Second, Provide the correct amount of soil nutrition

The concentration, content and composition of nutrients in the growth process of medicinal plants have a certain range. In the normal range, the plants can grow vigorously, and excess nutrients or undernutrition are not conducive to the growth of plants.

Outdoor planting nutrient supply: Outdoor medicinal soil can be fertilized in the form of base fertilizer + top dressing. Apply sufficient base fertilizer: generally based on organic fertilizer, combined with nitrogen, phosphorus, potassium fertilizer, generally apply organic fertilizer 30-40t/hm2. The organic fertilizer has a long-term effect, and the application of the base fertilizer can not only continuously supply nutrients in the whole growth period of the canna, but also prevent the premature aging of the plants. The amount of base fertilizer applied generally accounts for 70%-80% of the total fertilization amount. Top dressing: on the basis of the application of base fertilizer, reasonable topdressing. Medicinal plants is a crop that requires more fertilizer. The requirements for N, P, and K are as follows: N is the most, K is the lowest, and P is the least. The amount of fertilizer applied is generally 112.5-150kg per hectare.

Third, Regulate the growth of plants

In the process of medicinal plants growth, artificial regulation of the growth pattern of medicinal plants will greatly improve the photosynthesis efficiency of plants, thereby increasing production. There are two ways to regulate plant growth patterns: 1. Pressure regulation; 2. Pruning

Fourth, Control the growth environment

A good growing environment is critical to plant growth and yield. When the temperature and humidity of medicinal plants growth are too high or too low for plants, the plants cannot grow normally. When the temperature is too high in the late flowering stage, the binoids and terpenes are burned to reduce the quality of the flower buds. Better quality and higher yields can be achieved by controlling temperature and humidity.

Fifith. Harvest at the right time

For most varieties of medicinal plants, there is a 1-2 week harvest after flowering, and harvesting is achieved during the “harvest” period. When the grower harvests before the “harvest”, the harvested yield will decrease. After the harvest period, the quality of Huaye has been greatly reduced

When 70%-80% of the pistils of the plant turn brown, the inflorescences mature and the plants can be harvested.

Harvesting method: Cut from the bottom of the main stem of the plant, then hang the plant upside down, dry it in the dark for 10 days, or put it in a 30 ° C oven to dry. Turn on the fan when it is dry. The fan should be placed around the hanging plant to avoid direct blowing to the plant. The fan position should not be too low, otherwise dust may be blown.

Sixth, Choose high quality varieties and seeds

While all of the techniques and strategies described above have helped to increase medicinal plants production, the medicinal plants variety genes are decisive factors influencing plant growth, bud fertility, and ultimate yield.

Investing in high-yield varieties may be one of the best ways to increase the final yield (and the overall quality, efficacy and quality of the shoot).

1. Mature seeds Mature, healthy seeds are usually dark brown with dark stripes or spots. Plants with mature seeds will grow stronger and produce higher yields.

2. Seeds of female plants

Medicinal plants is divided into males and females. Only female plants can produce flower buds rich in HTC and CBD. Therefore, female seeds can be selected to obtain more active ingredients.

If the female and male of the seed cannot be distinguished at the time of sowing, the flower bud can be discriminated after the plant grows, and then the male plant can be removed to prevent pollination of the female flower to reduce the CBD yield and quality of the female flower bud.
