核桃简易温床嫁接,就是将核桃嫁接苗置于温床上,通过加温,促使愈合,然后移栽田间。采用这种方法,嫁接成活率一般可稳定在80%以上,适宜在广大农村推广。一、材料与工具(一)材料:锯末、塑料薄膜、竹笆、砖(或土坯)、高锰酸钾、细绳(或马蔺)、接穗、砧木,燃料(树枝、树叶、杂草)等。(二)工具:修枝剪、嫁接刀、温度计。二、简易温床的建造试验采用以下两种简易温床:(一)炕式简易温床(详见图1):在室外挖一长2米(或4米)、宽1.5米(或2米)、深0.7米的土坑作温床。在温床外距长边正中0.5米处,挖一个供烧火加温用的 Walnut simple hotbed grafting, that is, the walnut grafted seedlings placed in a hotbed, by heating, prompting healing, and then transplanted field. Using this method, the graft survival rate can generally be stabilized at 80% or more, suitable for promotion in the vast rural areas. MATERIALS AND TOOLS Materials: sawdust, plastic film, bamboo fence, brick (or adobe), potassium permanganate, cord (or iris), scion, rootstock, fuel (twigs, leaves, weeds) Wait. (B) tools: pruning shears, grafting knife, thermometer. Second, the simple hotbed construction test using the following two simple hotbed: (a) kang-type simple hotbed (see Figure 1): in the outdoor dig a length of 2 meters (or 4 meters), 1.5 meters wide 0.7 meters deep pit as a hotbed. In the hotbed outside the long edge of the middle of 0.5 meters, digging for a burning fire with
