枸杞的冬季修剪,杞农习惯于在落叶后至发芽前进行。近年来我们在巨鹿县薄庄村搞了不同时间冬剪对比试验,结果表明,落叶后进行太早,发芽前进行又太晚。这是由于枸杞枝条皮薄,含水分少,如修剪过早,剪口不易愈合,并常因失水造成干橛,剪口下枯死。特别是修剪量大时,由于伤口多,失水严重,还会使部分枝条干枯。而如果修剪过晚,因枸杞地上和地下部分春季开始生长都很早,也会因剪口失水而招致上述后果。据多年观察,2月20日左右,土壤20厘米深处达到0℃以上时,枸杞开始生长新根,3月初气温稳定在1℃以上时,树液就开始流动,3月中旬气温稳定在6℃以上时,芽子开始萌动。所以,冬季修剪一定要适应枸杞的这种 Winter pruning of Chinese wolfberry, Qi farmers accustomed to deciduous before germination. In recent years, we did a comparative study of winter shear with different time in Xiaolzhuang Village, Julu County. The results showed that it was too early after deciduous leaf and too late before germination. This is because the medlar thin branches, containing less water, such as premature pruning, not easy to heal the incision, and often due to dehydration caused by dry razor, notched cut dead. Especially when the pruning amount is large, due to many wounds and serious dehydration, some branches are also dried up. However, if the pruning is too late, the growth of the upper and lower parts of the wolfberry begins early in the spring and can also cause the above-mentioned consequences due to the incision’s dehydration. According to years of observation, on February 20, when the soil reaches above 0 ℃ in the depth of 20 cm, Chinese wolfberry begins to grow new roots. When the temperature is stable at 1 ℃ or above in early March, the sap begins to flow and the temperature in mid-March is stable at 6 ℃ above, Buds began to sprout. Therefore, winter pruning must be adapted to this kind of Chinese wolfberry
