核桃简易温床嫁接方法研究

Study on Method of Grafting for Walnut in Plain-type Hotbed

摘要:

在室外挖坑建造的简易温床具有不择燃料(树叶、杂草、树枝都可)、升温快、易控制、省工省料、费用低、嫁接成活率高(一般可稳定在80％以上)的特点，它解决了过去田间嫁接成活率低而不稳的问题，也避免了目前营造温室或大棚，需投入大量资金的问题，非常适宜在广大农村推广。

Abstract:

Constructing plain-type hotbed through digging pit outdoor has advantages over green house and plastic shed in lower requirement for fuel categories (such as leave, grass, branch and so on), fast temperature rise, easy control, saving in material and labour and high grafting survival rate (above 80% can be generally stabilized), it has solved the problem that the grafting survival rate in the field was low and unsteady in the past and also avoided issues met by present construction of green house and plastic shed for need by large amount of fund input, so it is very suitable for popularization in wide range of countryside area.
