葡萄常用插条繁殖。由于芽眼的萌发温度为10℃左右,幼根的形成则需要25℃左右,春季露地扦插往往先萌动、后生根,营养吸收与消耗不平衡,萌发的嫩芽易枯萎死亡,成活率低。1982年我场进行了火炕催根处理种条、地膜复盖定植试验,取得了较好效果。一、材料和方法(一)试验地土壤为淡灰钙土,面积25亩,前茬小麦。种条春季从外地调进,品种有龙眼、白羽、北醇、加里酿。以露地扦插为对照,重复3次。(二)火炕处理种条。在定植前20天进行,仿
Common grape cuttings breeding. Because bud germination temperature is about 10 ℃, the formation of young root needs about 25 ℃. In spring, the cuttings are usually germinated first, and then rooted. The imbibition of nutrient absorption and consumption leads to the death of germinated buds and low survival rate. In 1982, I carried out the field of kang rooting seed treatment, plastic cover colonization test, and achieved good results. First, the material and methods (A) The test soil is light gray soil, an area of 25 acres, the former crop of wheat. Seeds from the field in spring into a variety of longan, white feather, Bei Li, Gary stuffed. To open cuttings as a control, repeated 3 times. (B) Otter treatment of species. 20 days before planting, imitation
