Tea tree seed tea live

Large-scale development of tea gardens, direct seeding with tea is more convenient, and drought resistance after seedlings is also strong. However, the following points must be strictly controlled during sowing:

First, sowing time: Take the vast tea region in the Yangtze River Valley as an example. From the time of harvesting tea to the upper and middle of March in the coming year, all but the freezing period can be planted, but early sowing is appropriate. Autumn and winter sowing can eliminate the storage of tea, and can also be raised half a month in advance, which is more beneficial to the growth of the year. Specific sowing time, autumn and winter sowing in October-December, spring sowing should not exceed 3 months. According to the standard, the tea that meets the specifications should be selected. Soaking and germination should be carried out during spring sowing. After germination under the suitable temperature and humidity conditions, the soil can be sprouted rapidly. In autumn and winter sowing, the seeds can absorb water for a long time in the soil, expand the seed coat, and will grow long after the spring, without soaking and germination.

Second, the sowing method: the seed live, about hectares of tea with a standard 75-90kg in accordance with the provisions of the cluster distance, sowing each cluster 4-5, covering about 3cm, and then in the sowing line cover a layer of oyster shell, saw Sawdust, ferns, rice straw or wheat stalks, etc., to keep the soil sowing loose seedlings, help to emerge. The sowing depth has a great influence on the tea seedlings. In the production practice, there are often many cases of serious seedlings due to shallow or deep sowing, and the seedlings are generally deep; the seedlings are unearthed; if exposed to high temperatures and dry seasons, the embryos on the bare ground are burnt and wilted by severe sunlight. Affects the growth of tea seedlings; light green tea tends to expose the ground and is affected by cold winters or droughts and heat, reducing the emergence rate. Therefore, they all do not meet the requirements for rapid development. Generally in the middle of April and early May, seedlings can be successively emerged and the seedlings can be established in early June. Non-germinating tea or natural conditions in the year were not suitable, and it was often postponed until July. In order to make up for shortages of seedlings and improve the survival rate of the supplementation, one row of seeds may be sown at every 10-15 rows of rows of tea at the same time as sowing, or sowing may be carried out using unformed corners. The seeding amount is 5%-10 of the amount of seed used in the field. %. In this way, a nursery with supplements and deficiencies is set up on the spot, and the seedlings can be soiled and easy to survive.
