- 摘要:
- 以“天红2号”/SH40/八棱海棠成品苗和半成品苗为试材，分别于2015年10月31日、11月15日、12月5日和2016年3月12日、3月27日、4月7日进行栽植。调查了新栽幼树的成活率、萌芽时间、株高、干径、新梢数量、新梢生长量及成品苗中心干延长枝长度等生长发育相关指标。结果表明：秋栽各处理苗木成活率均达到98.85%以上，萌芽时间分别早于春栽3个时期2～9 d。11月15日栽植半成品苗株高净增长量为184.98 cm、品种干径净增长量为17.89 mm、新梢总生长量220.65 cm，均高于其它时期栽植半成品苗；10月31日栽植成品苗株高净增长量为143.36 cm、品种和中间砧干径净增长量为9.89 mm和9.26 mm、新梢平均数量为13.02个，中心干延长枝长度为140.57 cm，均高于其它时期栽植成品苗。因此，秋季适宜时期栽植的苹果苗木成活及生长发育情况优于春季栽植苹果苗木。
- Abstract:
- Two types of apple seedlings (‘Tianhong 2’/SH40/Malusrobusta Rehd.) were used as test material,and planted these apple seedlings on six different times (October 31,November 15,December 5,2015 and March 12,March 27,April 7,2016).The survival rate,sprouting time,tree height,stem diameter,number and length of new shoots and elongated shoot length were investigated.The results showed that the autumn planted seedlings survival rate reached 98.85% or more,the sprouting time was earlier 2 to 9 days than the spring planted seedlings.The budded seedlings which were planted on November 15 were higher than other periods planted budded seedlings on the amount of growth of tree height,cultivars stem diameter and shoots length,these three indexes were reached 184.98 cm,17.89 mm and 220.65 cm,respectively.The one year old seedlings which were planted on October 31 were higher than other periods on the amount of growth of plant height,diameters of interstock and cultivar stem,and the number of new shoots,the elongated shoot length,these five indexes were reached 143.36 cm,9.89 mm,9.26 mm,13.02 and 140.57 cm,respectively.Therefore,the survival and growth of apple seedlings which planted in autumn were better than those planted in spring.
