1. Skillfully put the tip: the early autumn shoots of citrus are also good results for next year. Therefore, in the middle of July, the uniform shoot, and when the new shoots grow to about 20 cm, pick up the heart in time to promote the autumn shoots. The late autumn shoots that were sent after mid-September were completely erased to avoid freezing damage. In addition to the autumn shoots, the overgrown trees are sprayed in the middle and mid-September to promote the flower top reflux of the plants, preventing the late autumn shoots and promoting flower bud differentiation.
2. Anti-Taiwan drought resistance: July-August, the temperature is high, the sunshine is strong, and the drought is prone to occur. It is necessary to combine the fertilization and do a good job of covering the ground of the orange orchard. When the soil is too dry, the conditional orange orchard should be flooded and drought-resistant in time. In addition, it is necessary to do a good job of binding the branches of the trees to prevent the new branches from being broken by the typhoon. After the typhoon, the pesticide manufacturer suggested spraying the new high-fat film + tree guards in a timely manner to disinfect and prevent the infection of the bacteria and reduce the source of the bacteria.
3. Pest control:
(1) Locuspid moth: unified shoot, when the shoot length is 3mm, and the shoot rate is more than 20%, the spray is highly effective against pesticide + new high fat film.
(2) cockroaches and black thorns, according to the occurrence of pests in the orange garden, timely spraying and prevention, and spraying 600 times of new high-fat film to improve the utilization rate of the medicinal ingredients and prevent the spread of the bacteria.
(3) Prevention and control of rust tick. The pesticide net is recommended to use 50% Tolk WP 2000 times plus New High Fat Film 800 times solution and spray 2-3 times for prevention.
