要使量天尺在高寒的东北地区安全越冬,应围绕温度、阳光和水分三个环节采取措施。具体要注意以下六点: 1.夏秋期间,要尽量使量天尺始终保持壮实,表皮呈深绿色。不能干瘪,不能被阳光灼伤,也不能因缺光、缺肥而呈黄绿色。如果已经嫁接,接穗不能被红蜘蛛吮吸成铁锈色,否则要影响砧木量天尺的耐寒性。接穗切顶后的母株,越冬前不要将长出的仔球全部取下繁殖,至少应留1～2个,否则砧木耐寒性也要降低。
In order to ensure the safety of winter days in the alpine region, measures should be taken in the three areas of temperature, sunshine and moisture. Specific attention should be paid to the following six points: 1. During the summer and autumn, we should try our best to keep the sky full and strong, the skin is dark green. Can not dry, can not be burned by the sun, nor because of lack of light, lack of fat and yellowish green. If you have been grafted, the scion can not suck red spider into a rust color, otherwise it will affect the rootstock on the scale of cold tolerance. Scion after cutting the top of the mother plant, before the winter do not grow out of the abalone all removed, at least 1 or 2 should be left, or the cold tolerance of the stock should be reduced.
