How to plant chicken bone grass

Chicken bone grass has the effects of clearing away heat and dampness, detoxification, relieving pain and promoting liver. It is a common traditional Chinese medicine, but the chicken bone grass planted by many people does not sprout, which may be the wrong way of planting, so how to grow it?

First, how to plant chicken bone grass

Chicken bone grass is generally used to raise seedlings and transplant and direct seeding planting, these two planting methods have their own advantages.

1. Seedling raising and transplanting

The amount of seed used for seedling transplanting is less, the seedling stage is convenient for centralized management, and the yield is higher. However, most of the harvested chicken bone grass has small main roots, many lateral branches, and the rattan stem is too long to meet the acquisition specifications, which makes it difficult to find a market and greatly reduce the commodity price.

two。 Direct seeding planting

The method of direct seeding planting does not go through the seedling stage, can not insert hedgerow, apply less chemical fertilizer (nitrogen fertilizer), can omit the seedling management and transplanting process, and the main root of the medicinal material is obvious, and the lateral root is less, so that the product specification and quality of the harvested product are better, easy to export and the commodity price is high. can achieve better economic benefits.

But the amount of seed used for direct seeding is more, and the yield is on the low side.

From the aspect of commodity quality of medicinal materials, the commercial specifications of medicinal materials produced by seedling transplanting are poor and do not meet the export standards (requiring large main roots, few lateral branches, shorter stems and fewer leaves). Therefore, direct seeding planting method should be adopted in the method of propagation.

2. Seed treatment

Chicken bone grass seeds are waxy coated, not easy to absorb water and expand, and the germination rate is very low under natural conditions, generally only 20%-50%, so the seeds need to be artificially treated before sowing.

The treatment methods usually include: warm water bubble seed; river sand skin scraping; sandpaper grinding seed; chemical dewaxing. Among them, the first three methods are simple and easy to operate, and can be carried out alternately with each other, which are the more commonly used methods; the method can not soak the seeds in water before rubbing the wax layer and sow the seeds directly after rubbing. However, according to the method, the seeds can be soaked in 25: 30 ℃ warm water for 2 days, and the water can be changed twice in the middle. After the seeds are fully absorbed and expanded, the seeds can be sown.

If it is unable to absorb water and expand, grind the skin with sandpaper or press the fine river sand and seeds into stone (or other containers) to rub off the waxy layer, so that the surface of the seeds becomes rough and permeable, then continue to soak with warm water, drip dry and sow the seeds. Or use the method after using the method.

The specific operations are as follows:

Sand wipe method: mix the seeds with about 5 times of clean, wet and fine sand into a cloth bag and rub them with your hands until the surface of the seeds becomes rough and lose luster, then soak them in cold water for 24 hours, pick out the swollen seeds that have absorbed water and prepare to sow, and the unswollen seeds are treated in the same way.

Hot water soaking method: according to the hardness of the seed, soak the seed in hot water with an initial temperature of 60% to 80%. The method is to put the seed in a tank or bucket, then pour hot water, raise the seed to the surface of the water by about 3 cm, and stir the seed with a stick to make the seed heated evenly. After being cooled by water and soaked in cold water for 24 hours, the swollen seeds were picked out for sowing, and the unswollen seeds were treated in the same way. Generally, a higher germination rate could be achieved after twice treatment.

Sand wipe warm water soaking method: put the seeds wiped by sand in a container, pour into hot water with an initial temperature of 60-70 degrees, soak the seeds 2cm on the water surface, soak them for 24 hours, pick up and sow, the effect is better.

After planting chicken bone grass, it is also necessary to do a good job in field management, so that chicken bone grass can grow healthily with high quality.
