Preventing the cold is to prevent the occurrence of cold damage. The rubber tree suffered cold damage. The light results in a decrease in the yield of the rubber tree. The severe one directly threatens the survival of the rubber tree and affects the economic efficiency of the rubber tree cultivation. Therefore, the following measures should be taken in the production of rubber: 1, spring planting rubber seedlings Spring planting rubber saplings (preferably nutritious bags), seedlings can be planted in the year when the growth of 5? 6 fluffy leaves, stems with high degree of corkation, strong cold resistance, is conducive to wintering seedlings. 2, a reasonable fertilization During the growing season, strengthen the tending management of the rubber garden, apply more organic fertilizer, and apply all the chemical nitrogen fertilizer required by the rubber tree before the end of September, so that the rubber tree grows robustly, reserves sufficient nutrients, and can stop before the arrival of the Cold War. The top buds grow to facilitate winter. At the same time, potassium fertilizer is applied before winter to promote plant maturity and increase cold resistance. 3, pruning Pruning can reduce canopy closure, increase forest illumination, and reduce “bad feet†and cold damage. After the rubber tree is cut open, the cut surface is vulnerable to cold damage. After cutting off, the surface is coated with a sealer, which is an effective measure to prevent cold cuts. Before the winter, weeding and defoliating and clearing forest belts to facilitate the exchange of cold and warm air in forest sections and the excretion of cold air are also necessary measures to prevent radiation and cold damage.
