一、11月份管理要点1.清园:将果园地面枯枝、落叶、杂草、碎石等一律清除干净,集中烧毁。2.浇封冻水:一般在冬至前果园要浇一次透水,待土壤松散后,再深耕一遍,以防冻害发生。若冬季干旱,冬灌次数不少于2次。因红地球葡萄根系主要分布在地表下10~30cm的土层内,抗寒性较差,一般地温在零下4℃时即可受冻,零下6℃持续两天根系就可全部冻死,故冬季的葡萄树冬灌防寒工作不可忽视。
First, management points in November 1. Qingyuan: the orchard ground branches, leaves, weeds, gravel, etc. all clean, concentrated burned. 2. pour frozen water: generally before the winter solstice orchard to pour a water, until the soil is loose, then deep plowing again to prevent frost damage. If the winter drought, winter irrigation times not less than 2 times. Due to the red earth grape roots are mainly distributed in the soil layer 10 ~ 30cm under the ground, cold resistance is poor, the general temperature at minus 4 ℃ when you can be frozen, minus 6 ℃ for two days can be all the roots freeze, so Winter grapevine winter irrigation cold work can not be ignored.
