1、管理措施:早春发芽前多次浇水(每次推迟2天开花)。2、树干涂5倍石灰乳、全树喷石灰乳液+豆浆适量+0.3%食盐水溶液。3、熏烟:花期气温降至-1.5摄氏度时在上风口点燃堆草或烟雾剂,根据预报进行,可提高果园温度2—3摄氏度,有效预防霜害。4、喷水或喷0.5%蔗糖水,霜冻前对果树进行喷水,水遇冷结冰,放出潜能,缓冲树体降温,同时在一定程度上加大水蒸气含量,能缓解霜冻危害。5、化学措施:秋落叶后,喷5000—6000倍赤霉素液或发芽前喷0.8—1.5%食盐水,或60倍的抑蒸保温剂,或
1, management measures: multiple watering in early spring before germination (each postponed 2 days flowering). 2, trunk painted 5 times lime milk, full tree spray lime milk + milk amount + 0.3% saline solution. 3, fumigation: flowering temperature dropped to -1.5 degrees Celsius lit up the mound or aerosol in the uptake, according to the forecast, can increase orchard temperature 2-3 degrees Celsius, effectively prevent frost damage. 4, water spray or spray 0.5% sucrose water, spray the fruit trees before frost, the water will freeze when cold, release the potential, buffer the tree to cool down, and to a certain extent, increase the water vapor content, can ease the frost damage. 5, chemical measures: autumn leaves, spray 5000-6000 times gibberellin solution or sprout before spraying 0.8-1.5% salt water, or 60 times the suppression of steaming agent, or
