| 摘 要： | 采用嫁接前1~5 d为1个时间段、嫁接后30 d分为10个时间段(共11个时间段)与每时间段内日均温、最高温、最低温、积温、降雨量、相对湿度6个气象因子组合成66个自变量因子,以核桃方块形芽接成活率为因变量进行逐步回归分析得知:嫁接前1~5 d时间段内平均气温、积温对嫁接成活率影响显著。以11个时间段的6个气象因子单独进行逐步回归得出:相对湿度对嫁接成活率无显著影响;嫁接前1~5 d和嫁接后1~3 d的气候条件对核桃芽接成活率最为重要,其次为嫁接后4~6 d,再次为嫁接后7~9 d,嫁接后10~12 d对成活率有一定的影响,嫁接12 d以后气象因子对成活率无显著影响。 |

| Abstract: | 1~5 d as a time period before grafting was adopted,30 d after grafting which was divided into 10 time periods(11 time periods),with average diurnal temperature,maximum temperature,minimum temperature,accumulated temperature,rainfall and relative humidity to form 66 independent variable factors, and took the survival rate of walnut bud taking as the dependent variable factor.From the stepwise regression analysis was obtained that the average diurnal temperature and the accumulated temperature in the 1~5 d before grafting had significant effect on the graft survival ratio.To take the 6 meteorological factors in 11 time periods to calculate respectively by stepwise regression analysis that the relative humidity had non-significant effect on the survival rate;the climate condition in 1~5 d before grafting and in 1-3 d after grafting was very important to the bud grafting survival rate,then in 4~6 d after grafting,finally in 7~9 d after grafting.Though the climate condition in 10~12 d after grafting still had somewhat effect on the survival rate,it already had no significant effect in 12 d after grafting. |
| Keywords: | Juglans regia bud grafting survival rate meteorological factor |
