Clone tea cultivation techniques
Tea tree is a perennial plant, the quality of the establishment of a garden, directly affect the yield benefits. The clonal hybrid tea plants have the characteristics of early germination, neat germination, rapid production, high yield, superior quality, suitable system, and strong resistance. Particularly suitable for famous tea production and mechanization operations. In order to give full play to the characteristics of high yield and high quality of tea varieties, appropriate cultivation techniques must be taken to achieve the intended purpose. Combining with the reality of our city, we will introduce the following points of cultivation techniques. 1. Prepare gardens for elevations below 1,200 meters, slopes less than 15 degrees, or slopes between 15 and 30 degrees, with deeper soil layers, no accumulation of water, and soil pH values ​​between 4 and 6.5. Tea plantation. First of all clean up the ground obstacles, the tea garden soil is dug deeper than 1 foot, flatten the soil, and the ground weeds can be buried in the soil or concentrated to be applied deep into the bottom of the planting ditch. And then dig planting trenches, planting trenches are generally 60-70 cm wide, 40-50 cm deep, 5000 kg of Mushi farmyard fertilizer, and 40-50 kg of phosphate fertilizer as the base fertilizer. Second, species selection According to the city's introduction of test and natural conditions and the production of tea, generally suitable for the production of green tea, tea leaf varieties of the main varieties, the main varieties are Fu selection No. 9 (early buds), Fuding Dabai (early buds), 131 (early buds), 311 (special early buds) Mengshan 11 (early buds), plum (high quality) and so on. Third, the planting specification l, in the shallow mountains Pingba area below 900 meters above sea level, the use of double row miscellaneous small nest planting. The planting specifications are as follows: large row spacing of 4.5 feet, small row spacing of 1 foot, and a nesting distance of 1.1 feet. Each nest contains 2 plants, equivalent to 5000 plants/mu. 2. In the mountainous area of ​​900-1200 meters above sea level, double rows of miscellaneous nests are used. Planting specifications are as follows: large row spacing of 4.5 feet, a small row spacing of 1 foot, a nesting distance of 0.9 foot, and 2 per litter, equivalent to 6000 per mu. Fourth, transplanting techniques and precautions l, transplanting time in October each year. When planting varieties can not be mixed. 2. All seedling preparations should be done well before the seedlings are shipped back. After the seedlings are transported back, they should be organized by human assault and rush to plant them. The one-time seedlings should be planted. 3. The roots of seedlings must not be in direct contact with fertilizers. 4. When the seedlings are planted, the root system should be stretched. Each plant should be divided slightly. Layers should be filled with fine soil and compacted. Continue to compress and tighten the roots and necks. 5, for too large seedlings, in order to reduce the loss of water, can be combined with the first stereotyped pruning, from the ground 15-20 centimeters to cut off the ground. 6, after the completion of planting seedlings poured root water. 7, keep a small part of the seedlings planted to fill the gap. Fifth, seedling management 1, after transplanting, in case of continuous sunny, watering once every 4-5 days, rainy days and cloudy days can not water. 2. When sprouting in the spring of the second year, check the survival of nursery stocks and make up for the lack of ready-made replacements. 3. After the seedlings have survived, they will be pruned for the first time before sprouting in the spring of the second year, and will be cut 15-20 centimeters from the ground. If the tea height reaches 25-30 cm at the end of the year, the first stereotyped trimming may be postponed for one year. Cut off the main stem per plant, not cut the collaterals (if planted, the tea tree has been pruned for the first time, until the end of the spring tea in the second year, the height of the tea plant reaches 35 cm or more, and the second shaping pruning can be performed) . In the second year after the first trimming, the second trimming was performed before the budding in the spring, and the clipping was improved by about 15 cm from the first trimming. The second stereotyped pruning followed by the third stereotyped pruning before the budding in the spring of the next year was about 15 cm more than the second pruning. After three times of shaping and trimming, the height of the tea tree has reached 45-50 cm, forming 4-5 layers of branches, combined with light mining of the topping and basic culture of the crown. 4. Special attention should be paid to the work of weeding, fertilization, and pest control during the seedling stage. 5. Within 2-3 years after planting, leguminous plants and green manure can be used in the garden. It can be buried in the soil during flowering, or the manuscript can be buried in the soil after harvest. 6. It is also a particularly effective measure to make grass in the seedling stage. The grass can moisturize, reduce weed damage and soil compaction, and increase fertility. Grass material can be used as a drafting rod and cut thatch.
