猕猴桃高位嫁接提前挂果试验初报

目的]为猕猴桃老果园改造提供依据。方法]以"米良一号"一年生健壮实生苗和连续开花结果的"米良一号"、"早鲜79-5"、"和平一号"、"武植三号"果枝为接穗,4℃贮藏后,在12月中旬以单芽帖接法接于砧木(10年生"武植三号")的1~2年生枝条上,每株50个接穗,观察嫁接后枝条的生长和开花结果情况。结果]一年生"米良一号"种子实生苗高位嫁接枝条长势良好,嫁接后第2年有30%~40%枝条开花结果。用"米良一号"、"早鲜79-5"、"和平一号"、"武植三号"果枝进行高位嫁接,翌年即可开花结果,且下一年能继续开花结果。结论]高位嫁接可促进猕猴桃提前开花结果。

Preliminary Report on Earlier Fruiting Test of Kiwifruit by Top Grafting

Objective] The aim was to provide the basis for rebuilding old kiwifruit orchard.Method] With 1 year-old of healthy seedling of Miliang 1 and continuously fruiting branches of Miliang 1,Zaoxian 79-5,Heping 1 and Wuzhi 3 as the scions,they were stored at 4 ℃,after that they were grafted on 1-2 year-old of branches of the rootstock(10 year-old of Wuzhi 3) with patch budding method in the second ten-day of December,each plant had 50 scions.After grafting the growth and fruiting conditions of branches were observed.Result] The growth of 1 year-old of seedling of Miliang 1 with top grafting was good,30%-40% branches could fruiting in the second year after grafting.The branches of Miliang 1,Zaoxian 79-5,Heping 1 and Wuzhi 3 with top grafting could flowering and fruiting in the second and the third year after grafting.Conclusion] Top grafting could promote flowering and fruiting of kiwifruit ahead.
