Organic tea planting: organic tea garden management, organic tea planting technology

Organic tea

The significance of organic cultivation in tea garden is to avoid the use of chemical synthetic pesticides and chemical fertilizers to produce tea. Its purpose is to maintain the health of tillers and consumers and to protect the ecological environment of the earth. The way of organic cultivation in tea garden lies in the use of organic fertilizers to supply nutrients for tea growth, and effective resource utilization of agricultural wastes; pest control requires non-pesticide control, including biological control, artificial capture, physical control and cultivation management control; weed control also requires non-pesticide methods such as mechanical and artificial weeding, planting green manure and ground mulching, etc. The operators of organic cultivation in tea gardens shall keep records of various cultivation and management operations, participate in the certification operations of relevant organs or organizations, and obtain the mark of "organic tea" products to facilitate the sale of the products.

In addition to drinking tea, the tea produced by organic cultivation can also develop diversified products of organic tea, such as organic powder tea, organic bag tea, cooking tea, tea wine, etc., so that consumers can have more choices and open up the tea sales market.

At present, the guidance situation of organic tea is summarized as follows: the implementation criteria of organic tea garden, the certification and specifications of organic tea are summarized as follows:

I. implementation criteria for organically cultivated tea gardens

(1) Environment: tea gardens where the air, water quality and soil are not polluted.

(2) fertilization:

Pure organic tea garden: do not use synthetic chemical fertilizers or growth regulators, but those who use unpolluted organic fertilizers or grow green manure crops for more than three years can be called pure organic tea products.

(3) Diseases and insect pests:

Pure organic cultivated tea garden: chemical synthetic pesticides are not used to control diseases and insect pests at all. the methods of biological control are as follows: using Trichogramma to control tea leaf moth, Wen's capture and planting, Shenze's leaf, sex pheromone to control tea leaf roll moth, lacewings, small pests and damage to thuri, tea silkworm, tea poison moth, debt-avoiding moth, inchworm moth and other Lepidoptera pests. Physical control: tea garden with yellow sticky paper can be used to control small green leafhopper, whitefly, thrips and aphids. High-pressure sprinkler facilities can be used to prevent drought. Manual capture method: tea silkworm, debt avoidance moth and inchworm moth can be used to reduce the density of insect pests. Cultivation and management: use pruning to remove diseased plants to keep the tea garden ventilated and avoid being too shady and wet.

(4) Weed control:

1. Artificial weeding:

The weeds that hinder the growth of tea trees, such as chicken vines, chicken dung vines and plough vines, are removed manually. The weeds near the tea canopy, such as Zhaohe grass, white grass, soil incense and Xianfeng grass, were dug up by artificial roots.

two。 Mechanical weeding:

Weeds that grow in the tea line and hinder picking operations and competition for nutrients can be used to fertilize and weed together during intertillage fertilization.

3. Ground cover:

Cover materials such as grain hull, peanut shell, bagasse and straw can be selected and applied between tea rows with a thickness of no more than 5 cm to avoid being too thick, resulting in poor soil ventilation or stagnant water in the rainy season.

4. Planting green manure crops:

In winter (November to December), lupin and ryegrass were intercropped in tea line, and sesbania could prevent weeds in summer, but lupin was the best in tea garden.

5. The cultivation of strong trees can naturally form a shading effect, and the tea line covered with pruned branches in summer or winter can also prevent the growth of weeds.

6. Appropriate selection of weeds with short growing period, short growth, soft stems and leaves and strong soil and water conservation function on creeping ground, such as Feisha grass, Lei Gonggen and so on.

II. Certification and specifications of organic tea

(1) Certification conditions:

1. Through the technical guidance and investigation of the tea production process, it is confirmed that it is cultivated in accordance with the implementation guidelines and field management methods of crop organic cultivation established by the Department of Agriculture and Forestry, and has complete management records.

two。 The collected tea products shall be sampled from the person in charge of each area of the tea conversion farm to the pilot farmers in accordance with the regulations and sent to the pesticide institute or relevant units for inspection to confirm that there are no pesticide residues and the data of the inspection report shall be attached.

3. The product conforms to the specification of organic agricultural products.

(2) specifications:

1. The appearance is tight and neat, hemispherical or strip-shaped, with good dryness and no coke.

2. The color is bright and dark green, and the golden edge of the tender leaves is hidden.

3. Resistant to brewing, soup honey green or golden yellow, clear and beautiful.

4. Delicate and elegant fragrance, no refined flavor, sweet and mellow moistening throat.

5. Adopt quasi-or pure organic cultivation, no pesticide residues.
