Kudingcha greenhouse cultivation techniques in North

50o ℃ above average absolute minimum temperature of many years of not less than a 10 ℃, the rainfall over the 150on1IIl, air relative humidity above 80% under the ecological conditions of growth. Kudingcha growth environmental conditions, both temperature, light, or air humidity, the protection of the environment can be achieved, therefore, we believe that North China Kudingcha protection in ecological simulation of cultivation. Spring of 1999, Chengmai County, Hainan Province from the bitter Chengmai Wanchang Ilex D field big introduction to greenhouse cultivation, has been more than 4 years, gained significant economic benefits, while the accumulation of a certain cultural experience. . 2 Kudingcha breeding methods commonly used planting, cutting for propagation, cutting propagation characteristics can maintain good plant. Kudingcha hard wood, dehydration and rapid, species need to be inserted is taken now, not waiting for a long. Old, young shoots can be as cutting, cutting length generally 8 ~ 10cm. ABT rooting powder before cutting fluid used to soak, soak a little longer the old branches, twigs shorter soaking time. Cuttings,[link widoczny dla zalogowanych], the cuttings cuttings buried part of the total 3 / 4, above the ground 1 / 4, part of the reservation exposed ground 2 to 3 leaves, each leaf to be cut by half. After the cuttings were irrigated, the film Shed coverage and good cultivators, weeding and fertilizing, watering and other management. 3 3.1 Greenhouse Cultivation close planting dwarf selection and soil preparation to planting soil should choose land Kudingcha deep, loose, slightly acidic, sandy soil rich in organic matter content to. Qian Yan shed height in lm or more. Deep plowing, leveling, rake thin, spaced 1.0m by opening ditches, deep 50cm, width 40cm, topsoil and subsoil should be separated. After ditching 10cm topsoil fill, conditional into the straw,[link widoczny dla zalogowanych], corn stalks and other about 10cm, then casing 10cm, Zaishi Tuza Fei 3000 - 4500kg / mu, overburden above the ground 10cm. Spacing can also be open hole. 3.2 seedling planting seedlings planted with improved varieties is the key to high yield Kudingcha premature. Requires planting height ~ - 50cm, diameter 0.5 ~ 0.8cm, developed root system intact, in order to survive rapid germination and more parts of low branches, dwarf plant type, high yield. Spacing by 1.0 × 0.6m of colonization, about 1,000 acre planting. Given enough time to shower planting roots in water. 3.3 The management of tea tree tea after planting, to keep the soil moist, often cultivation, weed. Seedling survival after the fertilizer should be applied thin, nitrogen, phosphorus and potassium ratio of 1:1:1. Young tea fertilizer to adhere to the \Of mature trees, to more nitrogen, nitrogen, phosphorus and potassium ratio of 3:1:1. Biogas fertilizer or top dressing fertilizer available, should be adopted in the bud, and after the capture,[link widoczny dla zalogowanych], delayed application of fertilizer to farmers focus on organic fertilizer. Young tea, be planted between rows of vegetables such as cabbage, radish b, coriander, so as to improve the land utilization and increase revenue. Summer heat, the leaves burn easily, can be high in the canopy of shade above the transmission network. Into the winter, Ilex in temperature below 2 ℃, there will be damage, through the plastic greenhouse insulation, moisture, high in winter is the main measure Kudingcha. Should pay attention to ventilation and cooling during the day,[link widoczny dla zalogowanych], the maximum should not exceed 35 ℃; at straws to cover insulation, the minimum not less than 5 ℃. 3.4 reasonable picking and pruning. Develop high crown picking principles are: to support mainly young trees, plastic, supplemented; mature trees in tea-based. Generally much more expensive than a long shoot, short shoot small mining; high spend many more mining, mining of low shoot less. Tea tree after planting should be promptly cut off the trunk, leaving the trunk height 40 ~ 50cm, forced dwarf, will be controlled at 1 ~ 1.5m tea below to promote branching, the branches grow from the horizontal Kudingcha. When the branches of l0 ~ 15cm topping, hanging branches that branch showing 30 - 50 degrees open. South to the north Kudingcha shed gradually increased, this can make full use of light, shoot to promote the balanced development of all sides to form a high canopy. 2 years after the species to adopt on behalf of the cut, plant height, according to the situation after the pruning. 3.5 Pest Control 3.5.1 Disease (1) anthrax: Bordeaux 1% solution or 50% carbendazim sprayed 500 times. (2) blight: the early stages, spraying 0.5% - 0.7%, half the amount of Bordeaux liquid, or 8o% Dyson sprayed zinc WP 600 times. (3) bud blight: WP 50% thiophanate 1000 times spraying. 3.5.2 Pest (1) aphids, red spider: The 5o% pirimicarb WP 1500 - 2000 times spray. (2) tea Li shield bug, leafhopper, leaf minor,[link widoczny dla zalogowanych], borer: a man killed, or diluted with 80% trichlorfon Pensha 1o00 ~ 1500 times. * 21 *
