旱坡地不同植苗处理对澳洲坚果定植成活率的影响

摘要

In order to solve the problems of low survival rate of transplanted seedlings , serious waste of seedlings , and high garden-building cost of macadamia nut in Guizhou provincial South Asia dry hot area in winter and spring , the author studied the influence of different transplanting dates , methods, and seedling types on the survival rate of grafted seedlings of macadamia nut Hinde (H2) through field tests.The results showed that the treatment of transplanting 2-year-old nutrition-bag seedlings, irri-gating with the water collected by tree dish , and covering seedlings with mulching film in September could acquire more than 94%survival rate of seedlings .Using this method to plant macadamia nut had high survival rate , and could effectively reduce the cost of building a new garden and enhance the utilization rate of grafted seedlings .%为解决贵州南亚热区冬春季干旱澳洲坚果植苗成活率低、种苗浪费严重、建园成本高等问题，以澳洲坚果Hinde（H2）嫁接苗为试验材料，采用田间试验方法研究了植苗时间、植苗方法和苗木类型对澳洲坚果植苗成活率的影响。结果表明：用2年生营养袋苗于9月采用树盘作集水盘浇定根水加覆盖地膜方法植苗，苗木成活率可达94％以上。该方法建园植苗成活率高，可有效降低新建园生产成本，提高嫁接苗利用率。
