- 摘要:
- 采用对新生枣头一级、二级、三级摘心及先对部分没有生长空间的新生枣头抹芽，再对保留下的新生枣头直接进行三级摘心的2种处理方法来研究对木质化枣吊形成的影响，以探究摘心和抹芽对红枣木质化枣吊形成的效应。结果表明：新生枣头随着摘心程度的加深，木质化枣吊形成的比例逐渐增加，由一级摘心时10%的木质化枣吊增加到三级摘心时的65%；吊果比达到1∶（6.2～8.3），是一般性枣吊吊果比1∶（0.26～0.61）的13倍以上，半木质化枣吊吊果比1∶（2.7～3.2），是一般性枣吊吊果比的5倍以上。抹芽后对保留新生枣头直接三级摘心及对骨干枝上抽生的枣吊进行摘心，使新生枣头上抽生的木质化枣吊达到56%，比对照高出43%;骨干枝上抽生的木质化枣吊达到58%，比对照的木质化枣吊（8%）增加50%。研究得出，抹芽与摘心促使养分更多地流向骨干枝及枣吊上，促使枣吊获得较多的养分而形成木质化枣吊，显著提高坐果率和产量。
- Abstract:
- The first level of newborn jujubes，secondary，tertiary pick first to part with no heart and growth space of new date head erased，again against the left new date head directly to the heart of the two pick three processing methods,the influence on the dates of the formation of the hanging wooden were studied，in order to explore pick on red heart and wipe bud wood of the formation of the effect of jujube crane.The results showed that new dates with the degree of heart head pick deepening，the date of the formation of the hanging wooden ratio increases，the heart by level 1 pick 10% of the wooden increased to 3 date hanging heart of 65% when picking；Hanging fruit than to 1∶(6.2～8.3)，was general date condole hanging fruit than 1∶(0.26～0.61) of the 13 times above，half of crane hanging fruit wood date than 1∶(2.7～3.2)，was common jujube hanging fruit hanging around 10 times than.Wipe after new dates to keep bud head directly to pick the heart and backbone three branches of smoke hanging on to pick the birth date heart，head of a new date of birth date hanging wooden reached 56%，43% higher than the contrast，the backbone of the branches of a birth date hanging wooden reached 58%，compared with the dates of woodiness crane (8%) increased by 50%.That test，wipe buds and pick the heart to more backbone branch flow of nutrients and went on the dates，prompting dates condole get the more nutrients and the formation of woodiness jujube dicks，improve fruit-set rate and yield.
