Detailed Explanation of Key Green Tea Cultivation Techniques and Management Methods

Green tea is a common type of tea in our country, and many people like to use it to make tea. It is currently cultivated in most regions. So what are the green tea cultivation techniques?

1. Site selection and land preparation

Green tea is suitable for growing in environments with deep soil layers, soil pH between 4-6.5, convenient transportation, no pollution nearby, sufficient nearby water sources, and a slope not exceeding 30 degrees. Therefore, when selecting soil, try to build the plantation in a place close to mountainous areas with sufficient water sources. After selecting the land, plow the soil deeply and apply sufficient base fertilizer. Then dig a ditch about 35 cm deep and about 30 cm wide for later drainage.

2. Seed selection

Select suitable varieties according to local climatic conditions. Generally, it is best to choose seedlings that are drought-tolerant, highly disease-resistant, have strong buds, dense sprouting, and small buds and leaves. If choosing tea seeds, it is best to select varieties that are healthy and plump, drought-tolerant, and highly disease-resistant for planting.

3. Sowing

(1) Sowing time: In southern regions, sowing is generally done from the end of November to March of the following year. In northern regions, sowing is generally done in mid-to-late March. Generally, do not delay sowing until after mid-April.

(2) Seed treatment: Soak tea seeds in water for several hours, then remove them and place them in moist sand for storage for about 20 days. When half of the tea seeds show radicles, they can be sown.

(3) Sowing: Sow the germinated seeds at a spacing of 25-35 cm, with about 3-5 seeds per hole, at a sowing depth of 3-5 cm, and finally cover with soil.

4. Transplanting

In regions where green tea is mainly cultivated with medium- and small-leaf varieties, there are mainly two types: single-row planting and double-row planting.

(1) Single-row planting: Generally, the row spacing is 1.3-1.5 m, the clump spacing is 25-33 cm, 2-3 plants are planted per clump, and 2500-4000 seedlings are used per mu. In tea areas with lower temperatures or higher altitudes, the row spacing can be appropriately reduced to 1.2-1.3 m, and the clump spacing reduced to about 20 cm.

(2) Double-row planting: A planting method developed on the basis of single-row planting. Every 2 rows are planted adjacent to each other with a small row spacing of 30 cm, the large row spacing is 1.5 m, the clump spacing is 25-33 cm, 2-3 plants are planted per clump, and 4000-6000 seedlings are used per mu. Compared with single-row planting, double-row planting forms a plantation and begins production faster while still maintaining convenience for future production management. It has gradually become the main planting method in northern medium- and small-leaf regions.

5. Management techniques after transplanting

(1) Water requirements: If there are continuous sunny days after transplanting, generally water once every 3-5 days. Each watering should be thorough so that the root soil is completely moistened.

(2) Thinning and replanting: After transplanting, check the plantation conditions at any time. If dead seedlings, overcrowded seedlings, or similar situations are found, replant or thin them promptly.

(3) Pest and disease control: After green tea seedlings are transplanted, their resistance is very weak, and various pests and diseases may occur, so prevention and control work should be done in advance.
