Tea tree branches pay attention to key points

The tea seedlings propagated by cutting can maintain the inherent characters and characteristics of the varieties. make the varieties unified, grow neatly, and facilitate the construction of high-yield and high-quality tea gardens. The main points that should be paid attention to when cutting tea branches are as follows:

The main results are as follows: 1. The current year branches of high quality, semi-annual, semi-lignified, pest-free, fat and green red bark buds are selected for cutting and breeding.

2. The new mud and fine sand without germs and impurities should be selected in the soil matrix, especially the coarse sand or clayey soil should not be used, and the non-granular stones and mixed planting roots should be removed. The surface of the cutting bed should be horizontal, and after proper compaction, the cutting should be carried out.

3. The cutting time is generally arranged from mid-late June to early July in summer and from mid-late September to early October in autumn.

4. Tea cuttings are made of 1CM thick tea strips with a length of 10-15CM. The leaves are cut by 90%, leaving 1/10 per leaf.

5. the base of tea cuttings was quickly dipped in a small amount of high concentration rooting powder, dipped in cutting or soaked in water for 6 to 24 hours with high concentration of liquor and water, and the soaking time was about short.

6. The cutting depth of tea cuttings is not less than 2/3, and the length of soil surface is at least 2/10, which is compacted after entering the soil. Generally, 20-250000 ears can be inserted per mu.

7. Pay attention to shading. 7-10 days after entering the soil, water should be watered once in the morning and once in the evening, and the amount of water should be watered thoroughly, and then watered once at about 4 o'clock in the afternoon, evenly sprayed, with the watermark clearly appropriate when the soil is clenched.

8. Tea cuttings can be sprayed with 0.5% urea solution once every 2 weeks after rooting. After the seedling height exceeds 10CM, properly increase the urea concentration and increase a small amount of potassium dihydrogen phosphate. About 180 days after the branch was buried in the soil, the root system of the branch grew to 10CM, and the texture of the shoot bud changed, and the garden could be transplant with soil.
