Citrus circumcision can prevent photosynthetic products from flowing to the roots, increase the accumulation of sugar in the branches and leaves, and thus promote flower bud differentiation in citrus. It is one of the effective measures to control the speed of vegetative growth, increase the number of flowering, promote the early flowering of young trees, and reduce the fruit drop in young fruit. However, if the ring cutting technology is improper, it will easily cause a large number of leaves to fall off, premature decline of tree vigor, and even death of trees.
Here are some ways to reduce the number of Citrus circumcised leaves:
1. Stage-circumcision: Each time the ring is cut, the base of the main wall is half a circle of the cortex, and after half a month or so, the wound is basically healed and then the remaining half of the ring is cut.
2, cut mouth to stay: depending on the thickness of the trunk, leaving 1cm to a few cm skin does not cut.
3, cut the package film: when the weather is not good, the ring cut to pack the film.
4. 2.4-D foliar spray: spray 5ppm 2.4-D plus 0.5% urea and 0.1% potassium dihydrogen phosphate after ring cutting, spray once every 10 days, spray 2-3 times continuously.
