Growth environment and characteristics of tea trees

Tea trees like warm and humid climate, and the area of 28 ~ 32 north latitude is the "golden line" for tea tree growth, which belongs to the best suitable area for famous green tea. Spring and autumn are suitable for planting tea seedlings all year round, and light is the primary condition for the survival of tea trees, neither too strong nor too weak, because tea trees have a special interest in ultraviolet rays, so high mountains produce good tea.

Morphological characteristics and appearance of tea tree Tea tree, formerly known as tea, is a shrub or small tree of Theaceae and Camellia, with hairless shoots. Tea trees like warm and humid climate. When the average temperature is above 10℃, the buds begin to germinate, and the optimum temperature for growth is 20 ~ 25℃. The annual precipitation should be above 1000 mm; Like light and shade, suitable for childbirth in diffuse light.

Tea tree life is divided into seedling stage, juvenile stage, adult stage and senescence stage. The tree age can reach 120 years, but the economic tree age is generally 40 ~ 50 years. Tea tree consists of roots, stems, leaves, flowers, fruits and seeds. Roots, stems and leaves are vegetative organs; Flowers, fruits and seeds are reproductive organs. The environment and conditions suitable for the growth of tea trees. The zone of 28 ~ 32 north latitude is the golden line for the growth of tea trees, and it belongs to the best suitable area for famous green tea. Longjing Village and Shifeng Mountain are located on the golden line of 3004 ~ 3020 north latitude, which is the golden zone for tea growth. In what environment do tea trees grow? When planting tea trees, the cultivated soil should be thick and soft, rich in organic matter, loose in soil, with strong air permeability and water and fertilizer retention capacity.

Tea trees are suitable for growing in a neutral environment, so the PH value of the soil should be kept at about 5-6. A suitable planting soil is of great help to the growth of tea trees. The suitable growth temperature of tea trees will also have a great influence on the growth of tea trees. The temperature should not be too high or too low. If it exceeds the suitable temperature range of tea tree, it will inhibit the growth of tea tree and reduce the yield and quality. Under normal circumstances, the suitable temperature range for tea tree growth is about 25 degrees, and the highest temperature cannot exceed 34 degrees. If it is exceeded, the growth rate of tea trees will be reduced or even stopped.

Moreover, the temperature should not be too low. If it is lower than 10 degree, the root will stop moving. Therefore, this is also the main reason why tea trees can't grow in winter, and sometimes it will cause freezing damage to tea trees.

Seedling stage of tea tree growth process: refers to the period from tea seed germination to tea seedling emergence until the first growth stop.

Juvenile period: refers to the time from the first stop of tea tree growth to the first flowering and fruiting.

Adult stage: refers to the period from the first flowering and fruiting to the first natural regeneration.

Aging period: refers to the time when tea trees turn from vigorous growth to aging or even death.

Tea planting time and method Tea planting time: Spring and autumn are suitable for tea seedling planting. Early spring (late February to early March) and late autumn (65438+1mid-October ~165438+1October) are the best planting periods.

Generally speaking, the soil requirement is sandy loam with a thickness of more than 1 m, without limestone and with good drainage. The organic matter content is above 1%-2%, and it has good ventilation, water permeability or water storage performance, and the PH value is 5~5. Light is the primary condition for the survival of tea trees, neither too strong nor too weak. Tea trees have a special hobby for ultraviolet rays, so good tea comes from high mountains.
