1 葡萄受害原因 1.1 旱害 冬季埋土浅,覆土不实,土壤沙性大,干燥,寒风直接吹透覆土,深入枝蔓,使枝蔓失水,地下结冰,供水困难,枝芽失水而干枯死亡。 1.2 冻害 埋土过晚,出土过早,覆土太薄,使枝、芽、根受冻。 1.3 热害 埋土过早,出土太晚,沟深,覆土太厚,湿度大,通气性差,使枝、芽、根受热,腐烂,失去生命力。 2 防寒十措施 2.1 灌足封冻水 葡萄下架后埋土前,灌水一次,应灌足灌透,以满足根系冬季活动需要。 2.2 枝蔓缚绑 葡萄埋土前,应将修剪后的枝蔓按株用草绳捆在一起,放入沟内,既便于埋土,又能避免出土时枝蔓受
1 grapes causes of injury 1.1 drought buried in winter shallow, soil is not covered, sandy soil, dry, wind blowing directly through the soil, deep branches and dendrites, so that the loss of water, underground icing, water supply difficulties, water loss and buds Death dead. Frozen damage buried too late, premature unearthed, overburden too thin, so that branches, buds, roots frozen. 1.3 Thermal premature buried, unearthed too late, ditch deep, overburden too thick, humidity, poor ventilation, so that branches, buds, roots, heat, decay, loss of vitality. 2 cold ten measures 2.1 filling enough frozen water grape grafting after the next, irrigation once, irrigation should be filled enough to meet the needs of winter root activities. 2.2 Manchu tied grapes buried before the pruning of the vine should be tied by the plant rope with straw, into the ditch, both for buried, but also to prevent the excavated when the stubble
