I. Variety selection
Should use resistance, high quality, high yield, good suitability, good commercial and suitable for market demand varieties, 80% using asexual seedlings, seed coverage rate reached 100%.
Second, planting
It should be planted in a single row or double row planting method with a row spacing of 1.2-1.8m. According to the actual situation in the field, choose autumn or spring planting.
Dig planting ditch before planting, apply enough base fertilizer, apply farm organic fertilizer, and replant tea seedlings.
Deep trench shallow method. When the tea plants were planted, the roots were plucked with yellow mud, and the tea plants were planted in the planting ditch to fill the fine soil, and the rhizosphere soil was pressed into the mud gates in layers to pour the root water.
Third, soil cultivation
According to the types of tea gardens, soil and climatic conditions, rational farming methods such as shallow tillage, medium tillage, deep tillage, and no tillage are used to avoid soil compaction, improve soil permeability, and promote fertility improvement. Conditionally equipped with tillage machines, promote the use of tea garden farming machinery to complete farming operations and cover the tea garden surface. Pruning branches and leaves should all return to the tea garden, increase the soil organic content of the tea garden, and return effective nutrients.
Weeding and weeding should be carried out regularly. Before spring tea and after the end of spring tea picking, we should cultivative and weeding once. The effect of applying organic basal fertilizer on tea gardens to improve soils is best.
IV. Water and fertilizer management
1. Apply water saving irrigation and soil testing and formula fertilization techniques.
2, strengthen the comprehensive management of nutrients, organic fertilizer and chemical fertilizers, base fertilizer and top dressing, fertilization on demand.
V. Prevention and control of pests and diseases
1. Equipped with at least one plant protection personnel to be responsible for the formulation of prevention and control plans, determination of prevention and control technologies; responsible for the procurement, use, storage, treatment and prevention and control of pesticides; and record of prevention and control files.
2. Implement unified defense rules to timely control the occurrence and spread of tea pests and diseases. According to pest control indicators and appropriate control period, agricultural, physical, biological and chemical technologies are used to prevent and control pests and insect pests. Comprehensive application of insecticidal lamps, sex attractants, and armyworm swatches should be used to minimize the use of chemical pesticides. The recommended pesticides should not be used. Forbidden to use pesticides.
3, establish a pest control file, record the time of control, land, control purposes, control measures, input name, dose, control effect, operator and so on.
According to pest and disease prevention and control indicators and prevention of appropriate period, prevention, comprehensive prevention and control; widespread application of light trapping, sex trapping, swatch trapping and other harmless prevention and control technology; preferred plant source, mineral source pesticides; priority use of mechanical methods weeding.
VI. Crown Management
According to the characteristics of the growth and development of tea plants and the environmental conditions in the tea gardens, reasonable use of techniques such as styling pruning, light pruning, and heavy pruning can be used to cultivate a tree trunk with a reasonable structure and robust growth.
Seventh, picking
Because of garden conditions, flexibility. According to the growth of tea plants and the requirements of the teas produced, the tenderness is the standard for all kinds of high-quality teas; the medium-harvesting is the standard for large red tea and green tea; the mature tea is the standard for selling tea; The picking is the picking standard for special teas such as oolong tea), and picking is strictly in accordance with the safe interval between pesticide and chemical fertilizer application. Pay attention to take-in and leave-in combination, leave a proper amount of leaves, and ensure that a new batch of fresh leaves is left on the tea tree each year. The tea farmer's experience is to keep the amount of leaves to "not explicit".
