The tea garden in Mangshi has a large area15.2Ten thousand acres, the area of ​​a cloned improved tea garden2.110,000 mu, accounting for the total area of ​​the tea garden13.8%, in the province is a relatively low rate of improved varieties of tea. Compared with planting seedling tea, the cultivation and management techniques of planting cloned tea are different. Improper planting and management will affect the survival rate and gardening rate. Therefore, it is necessary to promote the cultivation of cloned tea. Pay attention to some technical measures, which will help increase the survival rate and the rate of gardening.
　　1, check the quality of excavation, level and level the tea planting field, pull straight line calibration to excavate the planting ditch, and open the sloping field to open the planting ditch in the terraced field with large row spacing.1.7 Rice, deep planting furrow50cm, bottom width span>60cm, the surface layer of loam back ditch, raw soil cover surface, Then level the ground for planting tea. The quick digging time should be completed before the end of the month4 It is conducive to soil maturation, improves soil water retention, and improves survival rate.
　　2, control the quality of seedlings. Weak seedlings, small seedlings, and substandard seedlings are not planted. According to the climate, rainfall and temperature of Mangshi, the temperature and rainfall are different in different altitude areas of each town All are relatively high in 6-7Monthly temperature is as high as< /span>35-38C. Weak seedlings and seedlings have weak drought resistance and low fixed survival rate. Therefore, two-year seedlings or one-year-old strong seedlings and nutrient bag seedlings are generally used. Altitude1500Above meters, due to low temperature and rainfall Large, foggy weather, tea seedlings are conducive to survival, a year of strong seedlings, it is also easy to survive, the requirements can be slightly lower.
　　3, the quality should be strictly controlled when setting the value. According to the characteristics of the fibrous root system of the cloned tea seedlings, it is necessary to drill the holes and set the value and set the depth (depending on the length of the root system.20< /span>cm depth), stable, stable, cannot be broken, the weather should be selected when setting the value. Avoid setting values ​​on sunny and sun-exposed weather. Cloudy and light rainy days are more suitable for setting values. Planting per mu2400-3200Strains, can be single-line or double-line fixed value.
　　4, Strictly adjust the moisture content. Moisture is the key to ensuring the survival of tea seedlings, especially in the dry winter season. Most tea gardens dry up and die due to lack of tea. Newly planted tea seedlings should be covered with plastic film or mountain grass to maintain underground moisture, so that the tea seedlings can safely pass the dry winter season. This is a key technical measure to improve the survival of cutting seedlings.
　　5, strengthen the management of seedlings after setting. ①After setting the value of seedlings, guard against cattle, horses, and grubs. Eat insect bites, weeds must be removed frequently, and pests must be timely controlled when they occur. ②Before the dry winter comes, the rainy season is about to end span>10-11Monthly, a shallow soil loosening and cultivating work In principle, the loose soil cannot move the tea roots, and the soil is thickened.10About centimeters, to ensure the underground moisture, and to ensure that the tea seedlings can survive the winter safely. ③As the tea tree grows, it must be finalized year by year Plastic pruning, shaping a reasonable picking surface, (pruning in the same year is also conducive to increase the survival rate) for the high and stable production to lay a good foundation. ④according to the growth and age of the tea trees should be divided into batches Increase the application of fertilizers to increase the yield and quality of tea, and cultivate high-yield, stable, pollution-free, high-grade organic teas and tea gardens of famous and high-quality teas.
