What will happen to the fruit when the citrus is flooded? thank you
The affected orchards should dig ditches and open canals as soon as possible, quickly eliminate the accumulated water in orchards, reduce the groundwater level, accelerate the drying of topsoil and reduce root damage. For plants that have been flooded for a long time, some branches and leaves should be cut off to reduce water evaporation and speed up root recovery. Rainstorm erosion is easy to cause soil hardening in orange orchards, so it is necessary to loosen the soil in time to increase the oxygen content of roots in sunny days after rain; At the same time, the soil should be sterilized and disinfected, and the garden can be covered with quicklime. After waterlogging, the root system of the tree is damaged, so the respiration is weakened. At this time, the absorption capacity of root system to mineral nutrients is weakened. At this time, topdressing outside the roots is the fastest and safest way to supplement nutrition. We can choose products with regulating function such as potassium dihydrogen phosphate 500-800 times/1000- 1200 times and amino acid/alginic acid/humic acid 500-1000 times, and spray them once every 5-7 days. After the trees are restored, topdressing the rhizosphere in time. It is suggested that humic acid organic fertilizer (or rooting liquid fertilizer)+medium and trace element fertilizer+water soluble fertilizer should be used in combination with scarifying, and washed once every 15-20 days, 2-3 times! After the rainstorm, strong winds scratch leaves and fruits, break branches, etc. , resulting in multiple wounds. In addition, after the rain, the humidity is high and it is easy to be infected with germs. Attention should be paid to the occurrence of diseases and insect pests such as canker, acute anthracnose, resin disease, scab, red spider and scale insect. Especially the susceptible varieties of canker: citrus, Wogan, Maogu and so on. It is suggested to spray 2-3 times after the disaster and 2 times every 7- 10 day, which can effectively prevent ulcer disease. FYI
