Detailed Explanation of Key Points on Tea Seed Tree Planting and Management Techniques

SummarySelection of planting region and environment: Suitable for planting in southern China, acidic soil should be chosen, and the temperature during planting should be maintained at 16-18°C. Seed selection requirements: Select high-quality seeds with strong disease resistance and a high survival rate for germination. Soil selection: Apply an appropriate amount of organic fertilizer. Planting and transplanting: Disinfect the soil before planting. Fertilization management: During the growing period, an appropriate amount of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, and boron fertilizer may be applied. Disease prevention and control: Promptly clean up diseased parts and prevent and control diseases.

I. Selection of Planting Region and Environment

1. Generally, tea seed trees are suitable for planting in southern China. During this period, tea seed trees can be planted in high mountain and hilly areas. Regions relatively suitable for growth include Hunan, Jiangxi, Guangxi, Zhejiang, Henan and other areas, while they are widely planted in various regions from the Yangtze River basin to South China in China.

2. Tea seed trees are suitable for planting in acidic soil and prefer to grow in warm environments, so they are not cold-tolerant. During planting, the average temperature should be stable at 16-18°C. If the temperature is too low, it will cause flower drop. Moreover, the growth of tea seed trees requires sufficient light, otherwise it will lead to few fruits. If it rains for a long time during the flowering period, pollination will be affected.

II. Seed Selection Requirements

Generally, if you want to plant high-yield tea seed trees, you should select seeds with high quality, strong disease resistance, and a high survival rate. During this period, the selected seeds should be subjected to stratification and germination acceleration treatment. Note that they must not be exposed to the sun and need to be placed in a cool and ventilated environment for germination.

III. Applying Sufficient Base Fertilizer

1. When planting tea seed trees in spring, first choose acidic soil with strong water retention and smooth drainage. Never plant them in heavy clay or alkaline soil, otherwise root rot is likely to occur.

2. Before sowing, apply sufficient base fertilizer in the soil. Fertilization is mainly based on organic fertilizer, and a small amount of humus soil can also be added to the surface soil.

IV. Planting and Transplanting

1. Before planting, the soil needs to be thoroughly disinfected once to reduce the breeding of pathogens, which is beneficial to the robust growth of seedlings.

2. After planting, a small amount of fine fertilizer soil can be scattered on top, and then a layer of moist straw can be covered, which helps retain moisture and heat, and then the soil should be watered until moist.

3. When the seedlings grow 3-5 true leaves, promptly remove the wet straw for ventilation.

V. Fertilization Management

1. During the seedling period, pay attention to the amount of fertilization. Heavy fertilizer must not be applied during this period. Generally, nitrogen fertilizer is mainly used, and fertilization can be carried out according to the principle of small amounts applied multiple times, which helps promote the robust growth of the plants.

2. After the plants take shape, an appropriate amount of nitrogen fertilizer can be applied several times as a top dressing. When flowering, pay attention to applying phosphorus and potassium fertilizers. During the full fruit period, boron fertilizer can be applied once as a top dressing.

VI. Disease Prevention and Control

1. The common diseases of tea seed trees mainly include anthracnose, soft rot, root rot, etc. Such diseases can greatly reduce the yield of tea seed trees and may even cause the plants to wither and die during growth, so they must be prevented and controlled promptly.

2. Generally, when diseases are found, promptly clean up the diseased parts and use an appropriate amount of carbendazim or dexon for prevention and control.
