How to plant tea trees? What solar terms? What's the spacing?

(1) Variety selection: select excellent tea varieties with high yield, disease resistance, good adaptability and high superior rate. It is advisable to concentrate early, middle and late maturing varieties in the tea garden over 30 ~ 50 mu, each accounting for 1/3. In order to ensure the survival rate of transplanting, the roots of tea seedlings should be stained with yellow mud after they leave the nursery.

(2) Specification of tea seedlings: No tea root-knot nematodes, tea root scale, tea cake disease, root cancer and other dangerous pests and diseases. Basic standards: the seedling height is above 500px, the stem diameter is above 1.8mm, the stem is hard and more than two thirds is reddish brown. Minimum standard for annual seedlings: the height of seedlings is above 300px. The number of leaves exceeds 4.

(3) Going out of the nursery: Before going out of the nursery, irrigate and soak the seedbed. Carrying more soil will damage the root system. If the seedlings are too high, they can be pruned properly, and exotic plants and diseases and insect pests can be removed.

(4) Planting period: Generally speaking, the seedling germination period is appropriate. In spring, it is better to plant from beginning of spring to Jingzhe, and in autumn, it is better to plant in Xiaoyangchun climate before and after cold dew and first frost. As far as possible, choose cloudy days or after rain for planting, so as to facilitate survival.

(5) Planting specifications (methods): There are two main types. ① Two plants in a row: one plant is planted in a row (border), the spacing between plants (clumps) is 25-750px, and two plants are planted in each clump, leaving a gap of 3- 125px between the two plants to prevent the two plants from sticking to each other and affecting their future growth. ② Two rows of single plants: two rows are planted in one planting row (border) with a small row spacing of 20-750px, and the two rows of plants should be staggered (triangular planting) with a row spacing of 25-750px, with 2,500-3,000 seedlings per mu. ③ Close planting is planned, with the width of the border 1.3- 1.5m and the width of the ditch of 0.3m Four rows are planted in each border, the row spacing is 25-750px, and one plant is planted in clusters, with 4000-5000 plants per mu.

(6) Planting method: ① Planting large and small seedlings separately, with large seedlings planted in plots with poor growth environment and small seedlings planted in plots with fertile soil and good growth environment. (2) Before planting, you need to paste yellow mud. (3) When planting, dig a pit slightly larger than the root system in the planting ditch, fill in the soil and tamp it. Be careful not to damage the roots and rhizomes, and water them. (4) After planting, plant straws (about 250px thick) or plastic films should be laid to keep moisture and heat and inhibit the growth of weeds.
