Heavy summer tube after spring tea harvest
After the harvest of spring tea, the management of summer tea garden should be done in time.
1. Fertilize in time. Urea 15 per mu 20 kg, or Zhongcha No. 1 fertilizer 25 kg. Compound fertilizer with high proportion of phosphorus and potassium cannot be applied.
Otherwise, it will accelerate the reproductive growth of tea trees. Extra-root topdressing was carried out at the height of summer.
2. Ploughing and weeding. Since June, it has been removed every 25 days, with 10% glyphosate and 25% paraquat as common herbicides. Turning the tea garden once in July can not only turn the weeds between rows into the soil to mature the soil, but also cut off the soil capillaries and maintain the soil moisture.
3. Because of tree pruning. According to the growth status of tea trees, decide whether to prune or not. Most of the pruning work is carried out from late last month to early this month. Apply fertilizer in time after pruning, applying 250 kg cake fertilizer and 25 kg urea per mu, or rotten human and animal manure to promote early germination of tea trees.
4. Prevention and control of diseases and pests. Due to the high temperature and humidity in summer, tea plant diseases and insect pests such as tea caterpillar, tea inchworm, ring spot, anthracnose and bud blight are easy to occur, which should be controlled in time. Uranus milk per mu 10 ml plus 50 kg of water spray, control tea caterpillar, tea inchworm effect is good. Spraying 25% diflubenzuron suspension with 10 grams of water and 50 kilograms of water per mu can also effectively control the above-mentioned pests. Spraying 65% Dysenmeng zinc wettable powder 500 times, or 40% Laijidan wettable powder 600 times, can effectively control sheath blight, anthracnose, white star disease and wheel spot. Spraying with 1000 times of duofu mixed powder has a good effect on the control of bud blight.
