我县位于浙中偏西金衢盆地中段,极端最低温度可达-9.6℃(如1977年1月6日),所以在冬季经常有冻害的威胁,特别是对幼龄柑桔威胁更大。我场1985—1986年种的幼龄柑桔,占地15亩,2000株左右。由于管理上的问题,去年冬天自霜冻后有100余株柑桔皮层裂开。12月8日我们将其中20株采用1厘米宽、0.02毫米厚的聚乙烯薄膜捆扎于皮层裂开处,包扎紧后培土。今年3月15日扒开根际培土,解开包扎薄膜带,结果发现这20株柑桔,皮层愈合良好,全部恢复生机。而其它
My county is located in the middle part of the central western Zhejiang Jinqu basin, the extreme minimum temperature of -9.6 ℃ (such as January 6, 1977), so in winter frost damage often, especially for younger citrus threat. I farm 1985-1986 species of young citrus, an area of 15 acres, about 2000. Due to management problems, more than 100 citrus cortices broke apart since frost last winter. December 8, 20 of them we use 1 cm wide, 0.02 mm thick polyethylene film bundled in the cortex cracked, wrapped tight soil. March 15 this year, digging open rhizosphere soil, untied bandaged band, found that 20 strains of citrus, the cortex healed well, all revived. And other
