Short-spike cuttage technique for growing tea in autumn
At present, the development of famous and high-quality tea is the inevitable way for Yuyao tea to take benefit agriculture, and the effective way to develop early-growing varieties is short-spike cuttage, which not only maintains the excellent characteristics of the mother tree, but also shortens the breeding years, thus speeding up the speed of reproduction. However, short-spike cutting has strict requirements and strong technology, so it is necessary to control the four hurdles, namely, land selection, soil preparation and fertilization, cutting season and management.
I. selection of sites
The cuttage nursery requires the selection of slightly acidic sandy loam with flat terrain, loose soil and no wind damage. The practice shows that the paddy soil without stagnant water is the most suitable for cutting.
II. Soil preparation and fertilization
1. Soil preparation: the depth of the first comprehensive soil preparation is about 25 centimeters, and the second is combined into wow, and the restoration of ploughing with a depth of 15 centimeters is carried out.
2. Apply sufficient base fertilizer: vegetable withered, phosphate fertilizer and human feces and urine are mixed and used as base fertilizer after ripening. The amount of fertilizer per mu is determined according to soil fertility.
III. Cutting season and techniques
The suitable period for tea cuttage in production is from March to October. Especially in autumn (August-October) cutting is the best, during this period, the cuttings grow roots quickly, the seedling rate is high, and the management cycle is short, which is helpful to reduce the cost.
Before cutting, check the seedling bed first. If the soil on the seedling bed is dry, it needs to be watered and moist. When the soil does not touch your hand, you can start cutting. The row spacing is about 9 cm, and the plant spacing is about 3 cm. The degree is that the leaves do not overlap each other, so that 15-200000 cuttings can be cut in an area of 667 square meters.
cutting time is usually carried out before 10:00 in the morning or when the sun weakens in the afternoon. The direction of cutting leaves should be arranged along the main wind direction at that time, so as not to affect the survival rate by the wind.
IV. Management technology
The management of cuttings is related to the survival rate and seedling growth of cuttings. Management mainly includes shading, irrigation, fertilization, weeding, removal of buds and control of diseases and insect pests.

New technology of green prevention and control of growing tea
First, intercropping other tree species in the remaining corner of the slope around the tea garden, properly planting some ginkgo biloba, persimmon and other tree species (planting Eucalyptus grandis is strictly prohibited), improving the microclimate of the tea garden, increasing biodiversity, and reducing the occurrence of tea plant diseases and insect pests. Plant about 15 trees per mu, don't

Attention should be paid to tea management in winter
In order to make the tea garden put into production early in the coming year, more buds, strong buds, high yield, good quality and no pollution, strengthening the winter tube is the key to sell well in the morning market. With the advent of winter, tea gradually stops growing and enters a dormant period. At this time, the tea garden should do a good job in pruning tea trees and applying sufficient basic fertilizer.
