摘 要: | 根据枣股的有效结果年龄,把调查的125份枣品种分为4个类型:1~3龄枝结果为主;2~9龄枝结果为主;1~9龄枝结果为主和2~6龄枝结果为主,它们分别形成各类品种产量的85%以上。“1~3”型品种早果性强,早丰性好.但成龄树立体结果能力极差;“2~9”型品种早果性差,但开始结果后产量上升快丰产稳产:“1~9”型品种多数为小果型品种,虽早果性强,但早丰性差,盛果期树立体结果能力强;“2~6”型品种早果性较差,并有不同程度的大小年现象。

The Relation between Bearing Capacity of Mother Spur of Jujube and Ability to Set Heavy Fruits |

Abstract: | According to the continued bearing capacity of Mother spur of jujube,125 Chinese jujube varieties were classified into four types,iefruits were produced on 13 years old branches,1~9 years old branches,2~9 years old branches and 2~6 years old branches,those take 85% yield of all vari- eties.The“1~3”type posssses tne properties of early bearing and high early produotivity,but the stere- o-bearing ability of grown-up tree is much less.The yield of young trees in“2~9”type is low,and af- ter its first bearing the yield increases very quickly and stably.Most of“1~9”types are small fruit varieties,the output of young trees which are early-bearing is low,however,the grown-up trees pos- sesses strong stereo-bearing capacity.The“2~6”types is with less early-bearing ability,and alternate of bearing also occurs sometimes. |
