How to select the seeds of ladder forage? What are the methods of raising seedlings?

Tetranychus angustifolia, also known as cattail grass, is not only a perennial herbaceous plant of Gramineae, but also an excellent forage grass with high forage value. it is mainly distributed in Fujian, Jiangxi, Guangdong, Hainan, Guangxi, Yunnan and Taiwan. This kind of whole herb is used for medicine, as well as the effect of dispelling blood stasis and hemostasis, clearing heat and relieving cough. So how to choose the seeds of ladder grass? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to select the seeds of ladder forage?

The seeds of ladder grass are small, generally brown or dark brown. If you plant ladder grass, choose healthy and full seeds. The seeds of Tetranychus have a layer of hard shell, and the seeds need to be destroyed before sowing in order to germinate neatly.

If the amount of seeds is small, hard objects (such as bricks) are often used to destroy the seed shell; large planting area and large seed consumption are used to crush the seeds with a small rice grinder. Soak the seed shell in 30-35 ℃ warm water for 12-18 days before sowing to promote the germination of the germ and sow the seeds.

Second, what are the seedling raising methods of ladder forage?

1. Sowing time

The sowing time of ladder grass varies from place to place. To the south of the Yangtze River, spring sowing or autumn sowing is usually better, and autumn sowing is also available in North China, Northwest China and the south of Northeast China, but spring sowing is still better in autumn drought areas. Spring sowing should be done sooner rather than later, and sowing seeds should be grabbed to ensure seedling emergence.

2. Sowing method

The sowing methods of ladder forage grass are direct seeding and seedling transplanting. Direct seeding has the advantages of labor-saving, but its disadvantages are irregular seedling emergence, poor planting density and low yield, while the advantages of seedling transplanting are neat growth, reasonable dense planting specifications and high yield. Seedling raising and transplanting is recommended in production.

3. Seedling management

Ladder grass is generally sown 0.75-1.0 kg per 667 square meters, row spacing 15-30 cm, sowing depth 2-8 cm, and suppressed 1-2 times after sowing. Tetranychus likes cold and humid climate, has strong cold resistance and can survive the winter safely in cold and humid areas. Both seedlings and adults can withstand frost from minus 4 ℃ to minus 3 ℃. The heat resistance is relatively weak, and it is difficult to pass the summer when the temperature is above 35 ℃.

4. Pest control

Tetranychus grass has few diseases and insect pests and generally does not need to be treated with medicine. When there are locusts and aphids in the seedlings, trichlorfon, dipterex and imidacloprid can be sprayed in a certain amount. If there are no harmful diseases, chemical control can not be carried out.

The above is the introduction of ladder forage, which is a perennial cultivated forage. This species is the best feed for livestock. It is the most widely used in the world and is more palatable to horses and mules.
