How to choose Niu Di seed? What are the methods of raising seedlings?

Niu Li, also known as Taurus tail and burrowing wind, is a typical plant of medicine and food homology, known as "Southern Ginseng". With the strengthening of people's awareness of health care, the rising market price of cattle, coupled with the excessive mining of wild resources, artificial cultivation is slowly rising. It is understood that artificial cultivation of cattle is mainly through cutting propagation and seed propagation to raise seedlings. So how to select seeds and raise seedlings? Let's get to know it.

How to choose Niu Di seed?

There are still many varieties of cattle in circulation on the market, so it is recommended to choose varieties according to the planting season of cattle, such as early and mid-maturing varieties when sowing in spring, and mid-and late-maturing varieties if they are planted in autumn. In addition, when collecting seeds, we should also pick out necrotic seeds and choose high-quality seeds for sowing, so that its output will be larger, more lasting and more cost-effective.

What are the methods of raising seedlings?

1. Selection and treatment of seeds

You should choose full Niu Dai seeds, then soak in cold water and Kailun fungicide for an hour, then you can order a cup directly. It is worth noting that when ordering the cup, it is not appropriate to put the seed too deep, just put the soil slightly over the seed.

2. Seedling raising method

The seedling raising method of "small arch shed + nutrition cup" is adopted, which is more flexible, convenient and effective, which can prevent the seedlings from frost damage, and the plastic film can be opened when the temperature rises. The use of nutrition cup to raise seedlings can not only fully ensure the integrity of the roots of seedlings, but also ensure that the roots of seedlings will not be damaged when transplanting. In addition, it should be noted that humidity is critical when planting, and the soil of the nutrition cup should be drenched with water the day before the seedling is raised.

3. Cultivate strong seedlings

After 50% seeds germinate, potassium dihydrogen phosphate can be drenched 1000 times with water, which can have the effect of strong seedling. Before the seedling grows 2-3 leaves to transplant, Yuhualing No. 1 is drenched 2 times for 3 times, which can supplement the nutrition needed for seedling growth, promote the growth of seedling root system, establish huge root tissue, make the seedling more robust, the leaves are dark green, and improve the survival rate of seedling transplanting.

4. Seedling stage management

① seedlings are sprayed with 1-2 compound fertilizers per plant after new vines are produced, and the fertilizer should be more than 20 cm away from the roots of the seedlings. In the second year, 200kg long-acting compound fertilizer was applied per mu of furrow, combined with ploughing and weeding; when ② seedlings grew to 60-70cm, the tail should be cut (once every three months) to increase the number of branches and leaves; ③ frame is conducive to ventilation and light, increase photosynthesis, reduce the occurrence of powdery mildew, and is beneficial to seed yield and quality.

Generally speaking, the artificial cultivation of Niu Li has been very extensive, covering many planting areas. In order to shorten the rooting time and improve the seedling emergence rate, attention should be paid to seedling raising techniques when using seed breeding. Of course, the premise to choose a good variety is also very important.
