Management of tea gardens in autumn and winter generally starts from October each year and ends in February of the second year. After October of tea plantation, the shoots and leaves of the shoots basically stopped growing, while the underground roots were relatively active. During this period, soil management was strengthened to create favorable conditions for the root activity, which was conducive to promoting the quality and yield of spring tea in the coming year. At the same time, winter tea pests and various pathogens have weak activity and poor resistance. At this time, pest control can be more effective. Therefore, it is very important to manage the tea gardens in autumn and winter. When the tea areas are not mistaken for farming, do the following in a timely manner:
1. Soil management work
(1) Deep weeding. After growing and picking the tea tree in spring and summer, the tree body has consumed a lot of nutrients, and the soil between the rows has become very compact. Deep plowing in autumn and winter is conducive to loosening the soil, improving the physical and chemical properties of the soil, promoting the growth and development of tea roots and soil permeability, and is very important for restoring the vitality of tea trees. Deep plowing should generally be carried out from the beginning of October to the beginning of November every year, with a depth of about 20 cm. It is too deep to injure the root system and affect the normal growth of tea plants. Combine the weeds with deep plowing and bury them in the soil.
(2) Deep application of organic fertilizer. The accumulation of nutrients in the tea tree body in autumn and winter has played an important role in spring shoot shoots in the following year. Base fertilizer should be used to supplement nutrients. The period from October to November is the peak period of the growth and development of the roots of tea plants. Therefore, the time of applying basal fertilizers mostly occurs from October to November, and the latest time does not exceed the end of November. The type of basal fertilizer is dominated by organic fertilizers, such as pig manure, compost, and cake fertilizer, together with a small amount of phosphate fertilizer. The amount of basal fertilizer generally accounts for 30% of the annual fertilization amount. The amount of fertilizer applied to the tea plants in different stages of growth varies. Young tea gardens usually apply 1000-1500 kg of farmyard fertilizer per acre, or 100 kg of cake fertilizer, and apply 20 kg of phosphate fertilizer; adult tea gardens use 2000-2500 kg of farmyard fertilizer per acre, or 200-250 kg of cake fertilizer, plus 50 kg of phosphate fertilizer. Fertilization should be deep and deep along the rows, but it can also be combined with deep tillage. After the application, cover soil to prevent fertilizer loss. For stepped tea plantations, fertilizer should be applied inside the steps.
(3) Tea garden soil. Choose some exotic clean soil, such as red soil, yellow loam soil, mud, etc., on the surrounding of the tea plantation or on other slopes, and cultivate it at the base of the tea tree, with a thickness of about 10 cm. It is generally required that viscous soil tea plants be cultivated into sandy red soil, sandy soil tea gardens should be cultured into cohesive soil, and low-yielding tea plants and aging tea plantations should be cultivated into red and yellow soils. Cultivating soil can thicken the tillage layer, increase soil vitality, prevent soil "aging", have a significant effect on promoting early spring tea germination and improving the quality of fresh leaves.
2, tea garden pruning work
Tea tree pruning in autumn and winter is an important technical link to seize the high quality and high yield of spring tea. Attention should be paid to the adjustment of trees. For adult tea gardens, light pruning, deep pruning, and edge pruning should be combined. For young tea trees, cultivation should be , Stereotype pruning, cultivating the crown.
(1) Light trim. A light pruning is performed once a year for the tea plantation that has been put into operation in order to control the tree height and cultivate the crown picking surface. Generally cut the crown 3 to 5 cm, to the crown surface smooth, so that the height of the tea tree is controlled at about 50 cm. The time of pruning should be determined according to the altitude. The low mountains can be carried out from October to November. The tea area above 900 meters above sea level can be carried out in February of the year.
(2) Edge trimming. For the tea gardens that have been closed to form a line with no ventilation between the lines, the edge of the tea plantation must be trimmed, and the cross branches between the rows should be cut off to maintain a uniform ventilation path and operation space between the tea garden rows of 20 to 30 cm. This agronomic measure is also very beneficial. Prevent tea plant diseases and pests.
(3) Deep trim. For the tea gardens with more thin and weak branches and chicken claws, the output of the chicken branches should begin to decline, deep pruning should be carried out. Branches 10 to 15 cm above the canopy surface can be cut off, and all the branches of the chicken claws can be cut off to facilitate the germination of the next year. neat.
3, pest control work
After the end of the tea season, with the gradual decrease in temperature, pests and diseases began to enter the overwintering stage. In order to prevent the occurrence and harm of spring tea pests in the following year, clean garden spraying should be done:
(1) Completely clean the park. The weeds and litters between the tea trees are the hidden places of pests and germs. Clearing the garden in time will help reduce the number of overwintering pests in the tea garden. One is to remove the diseased leaves and worms on the canopy in time during pruning and deep ploughing. The other is to remove the litters between the rows and all around, then burn them together to eliminate overwintering germs and insect sources.
(2) spray park. The overwintering pests of tea trees mainly include small green leafhoppers, tea-footworms, tea caterpillars, and crickets, and crickets. After the autumn tea is harvested, if the pests and diseases are still very serious, pesticides can be sprayed once in the beginning of October for prevention and treatment. Then, from late October to early November, the entire tea plantation should be treated with a 0.7% lime half Bordeaux mixture or a 0.3-0.5 Baume degree lime sulfur agent. When spraying, the tea should be sprayed from the top and bottom, inside and outside, and the front and back of the blade. The weeds on the ground and the branches in the canopy should also be sprayed to improve the control effect. The closure of the garden will end at the end of November.
4, tea tree antifreeze work
(1) fertilize earth. Before the onset of the cold wave, it is necessary to timely do a good job of fertilizing and fertilizing soil. Applying some cow manure, phosphorus and potassium fertilizers and other warm fertilizers between the tea garden lines will help increase the soil temperature. After fertilization, soil should be cultivated in time, and new soil with a thickness of about 10 cm should be cultured at the base of the tea tree to prevent the root from being exposed to frost damage.
(2) Paving between rows. Local materials can be used to cover the tea tree rows and roots with firewood, rice straw, straw, etc. to help increase soil temperature and maintain soil moisture.
(3) cover the cover. Before the onset of the cold wave, the young tea gardens can be covered with straw, weeds, or films. After the spring is opened, the coverings are peeled off in time to prevent the tea trees from freezing and promote the early spring sprouting and development of the tea trees. The purpose of high quality and high yield of spring tea.
