Improved varieties and transplanting techniques of tea trees

1. Varieties suitable for making flat green tea: (1) Longjing 43: early hair teeth, strong cold resistance, high yield, but poor tolerance to high temperature, easy to develop leaf blight. It is suitable to plant flat tea in mountain areas and alpine tea gardens. (2) Wuniu early: early germination, strong tenderness, medium germination density, good quality of flat tea. (3) Pingyang extra early: sprouting early, growing strong, not blooming, making flat tea with green color, strong aroma and excellent quality. 2. Suitable varieties of strip green tea: (1) Yingshuang: early germination, strong tenderness, long picking period, yellow-green bud leaves, many hairs, high and fresh fragrance, strong taste, excellent quality and strong cold resistance. (2) Zhenong 113: early germination, strong tenderness, yellow-green bud leaves, many hairs, needle-shaped tea with delicate appearance, green color, high flavor and good quality. Strong resistance. (3) Cuifeng: early germination, high yield, emerald green buds and many hairs. The needle-shaped brown is green and moist, the fragrance is high and long-lasting, the taste is strong and fresh, and the quality is excellent. It has strong cold resistance. 3. Tea seedling transfer technology: (1) transfer time: in the areas where there is no cold and low temperature in winter and good water conservancy conditions, autumn planting is better than spring planting. When transplanting in the early and middle of November, there is a 3-month period of root recovery and growth in the same year, and the spring of the following year will sprout and grow leaves like normal plants, which is not only beneficial to get through the summer of high temperature and drought, but also can be put into production six months to one year earlier than that of spring planting. (2) soil requirements of tea trees: tea trees like to grow in acidic soil. As long as the newly reclaimed barren hills are acidic red-yellow loam, any soil with plants such as Osmunda Osmunda, thatch and gold thorn is suitable for growing tea. Weak acid or neutral soil is generally not suitable for growing tea if it used to be a good field for growing rice. If you want to grow tea, one is to do a good job of trenching and drainage to lower the groundwater level to less than 80 centimeters; second, the raw soil (that is, mud) of the planting line must be turned over, and the roots of tea seedlings must be planted on new soil, not on ripe soil. (3) transplanting method: the degree of close planting with a row spacing of 1.2mi 1.5m and a plant spacing of 0.3m, 2 plants per hole and 3000 tea seedlings per mu. After planting, the roots are firmly fixed and watered in time, and then covered with loose soil. One to two weeks after transplanting, if the temperature is high on a sunny day, it will be watered twice a day. (4) pruning of tea seedlings: after planting, tea seedlings must be cut off the tender branches in time to reduce their water evaporation as far as possible so as to improve the survival rate. Generally, after colonization, the tea seedlings can be grown into 6 leaves, that is, 20ml, 30cm in height.
