Kuding tea dwarf dense planting high yield technology
Kudingcha is cold, detoxifying, bactericidal and anti-inflammatory, and its taste is bitter and sweet. It is a rare health drink and medicinal plant. The development of Kuding tea has high economic benefits. Its dwarf and dense planting high-yielding cultivation techniques are as follows: (1) The selection and preparation of land for Kuding tea plantation should select valleys or slopes with low altitude, back-to-north wind, and back-to-west drying. The soil thickness and fertility are required, and between ph6.5-7. Slightly acidic or neutral loam and sandy loam. The whole raft or raft shall be leveled and the gutters shall be well opened; trenches shall be digging at 1.2m spacing, 70cm in width, 70cm in depth and 20-30m in length. Apply sufficient amount of soil miscellaneous fertilizer in the ditch, mix and backfill with soil, backfill about 10 cm above the ground. (ii) Planting 1111 strains per acre with a height of 1.2 meters and 0.5 meters from the planting height. When planting, take a 30-cm deep hole in the center of the ditch, remove the Kuding tea seedlings from the nutrition bag, place them in the center of the pit, let the roots stretch, cultivate the soil (the root system can't touch the basal fertilizer), compaction, and pour enough water. Cover shading for 10 to 15 days. Planting time should be selected from March to April. (3) To force dwarf kudingcha to survive after the shoot reaches a height of 40 cm, timely topping buds should be promoted to promote branching and forced dwarfing. At the same time, cytokinin hormones can be used to promote lateral bud germination. Branches of 10 to 15 cm are to be topping, and the branches are erected so that the branches are 30 to 40 degrees apart. After 4 to 6 prunings, the purpose of forced dwarfing can be achieved within one year. (d) Strengthen management After the planting, the soil should be kept moist and loose, and weeding and weeding should be carried out frequently. After survival, thin application of human excreta or 0.5% urea plus 0.2% potassium dihydrogen phosphate, followed by fertilization once every 15 days. The pests and diseases were found to be sprayed and prevented in a timely manner. It was also possible to spray once 0.3-0.4 Baume degree lime sulfur to control pests every 20 days. In summer, Kudingcha grows slowly, leaves are prone to burns, and the function of the leaves declines or even falls off. A simple bamboo and wood shed (4 to 6 meters high, 4.8 meters wide and 20 to 30 meters long) can be placed every 4th row. The shade is 45% to 60%. Kudingcha showed freezing injury when the temperature was lower than 2°C. When it was cold from the middle of December to the end of February, it could be insulated and moisturized by plastic greenhouses. However, it was necessary to open two doors for ventilation and cooling in sunny days, and cover straw insulation on frosty evenings. (5) Reasonably picking Kudingcha can be picked multiple times throughout the year, but it must be reasonable, timely and appropriate. The principle of picking is: saplings are mainly cultivated, and plastic surgery is supplemented; The general tip is multi-picking, with little shoots and low shoots; The tip of the tip leaves are picked, but the leaves are not taken at the end. Tea picking should be followed by cultivating, weeding, fertilizing and spraying.
