Recently, at the Xinshi Tea Garden Management Technical Training Conference held in Yuanping Township, Yuanyang Township, Nanjiang County, Li Mingfu, the tea cultivation expert of the County Agriculture Bureau, gave a detailed explanation on the management of the new plantation tea garden, he said, under high temperature weather conditions. , The management of new plantation tea garden should grasp several key points -
Drought-resistant seedlings
The main technical measures for drought and seedling protection are:
Tea-shopping: The tea-shop is to lay straw or wheat straw with a thickness of about 10 centimeters on both sides of the new planted tea seedlings before the onset of the dry season, and apply a layer of fine soil to the grass. It is advisable to use tea as early as possible.
Shallow cultivating soil: generally conducted before the onset of the dry season. If the soil is formed by drought, it is not appropriate to cultivate the soil loose to avoid the tea seedlings from dragging. However, about 30 cm around the tea seedlings can be accompanied by a layer of fine soil to reduce the amount of soil. Evaporation of water.
Watering: Watering should pay attention to one-time drenching, or you can use thin farmyard fertilizer to water (water to fertilizer ratio is 10:1). After irrigating for the first time, dilute manure water (in a ratio of 1:10) was poured after 3-5 days and gradually increased. You can also cook the cake fat (usually about 15 days), then watered.
If you suffer from drought, you should take the following measures to recover: First, clean up the dead branches after the high-temperature weather is over; second, rationally add nutrients, and after the occurrence of drought, apply some human excrement or cooked cake fat. 1% urea or 2% ammonium sulfate and other liquid fertilizers are used for root dressing; at the same time, potassium dihydrogen phosphate is sprayed on the leaves (0.5 kg/mu and 100 kg/mu). In this way, the injured tree body is repaired by absorbing certain nutrients, and the cold resistance can be improved in winter.
Grass fertilization
Since the tea tree canopy has not been formed in the newly planted tea garden, the coverage of the tea garden is low, and the weeds are prone to breeding. The weeds should be promptly treated according to the growth of local weeds. The weeds should be planted before the weed grass seed mature in the season to reduce the next season. The breeding of weeds. At the same time, weeding can be combined with shallow tillage work.
Fertilization, dosage and fertilization time are as follows:
The first-year tea in mid-to-late mid-April, 100 kg of cake fertilizer per mu or 1000 kg of farmyard fertilizer. The second-instar tea should be applied for 150 kg of cake fertilizer per acre or 1000 kg of farmyard fertilizer in the middle and late September. Three-infant tea should be 200 kg per mu in the middle and late September or 2000 kg of farmyard fertilizer.
Shaping
Stereotype trimming is generally performed in 3 steps.
The first pruning: After the planting, the height of the pruning is suitable for 15-20 cm from the ground, and it is advisable to postpone the growth of the poor tea.
The second pruning: one year after the first stereotyped cut, the normal growing tea tree can be pruned for the second time. The height of the tea tree is increased by about 15 centimeters for the first time. It is also advisable to advance with the spring tea. In each tea season, depending on the growth conditions, the top was to be promoted to further promote branching, expand the canopy, and increase the density of tea buds.
The third pruning was performed after one year of the second stereotyped pruning. The pruning height was increased by about 15 cm on the second incision, and the shading was performed in the summer and autumn tea. For the tea tree with strong tree vigor and good water and fertilizer conditions, spring tea can be used for tender and famous tea in the early period. After 20 days, picking is finished, and the third type of pruning is performed.
After shaping the pruning, the canopy expands rapidly and has a strong skeleton. Afterwards, spring tea can be used to select famous teas in the early stage, picking is finished early in the middle period, and 5-10 cm in the previous year can be trimmed and pruned to make the canopy slightly. Curved, can be officially put into production.
