设施杏树生长发育规律的研究

本试验以金太阳和骆驼黄杏为试材,对设施栽培杏树果实与新梢生长发育和花芽分化进程进行了研究.结果表明设施中的两个杏品种,不论是正常区还是高温区,果实的纵横径生长都呈"双S"生长曲线,但是高温区的果实纵横径的生长量高于常温区.设施条件下金太阳杏树的新梢生长的快速生长出现次数没有改变,与露地杏树相同均为三次,但生长速率大,维持时间长,出现的时间也与露地不同.设施杏树果实与新梢之间在生长时间上存在有交替现象.设施内金太阳杏的花芽形态分化进程从5月20日开始到10月下旬结束.

Growth and development of apricot in greenhouse

This paper used "Jintaiyang" and "Luotuohuang" growing in greenhouse as materials,and studied the growth and development of apricot fruit,shoot and the course of flower bud differentiation.The results indicated that the growth of fruit for the both cultivars was of "double S" growth curve,but the growth quantity in high temperature plot was larger than that in normal temperature plot.The number of shoot rapid growth period of("Jintaiyang") did not changed in greenhouse,existed three rapid growth periods as same as in the open field,but the time of emergence varied,the growth speed and maintaining time was faster and longer than that in the open field.The growth of apricot alternated between the fruit and shoot in greenhouse.The course of flower bud(initiated) on May 20 and ended in last ten day of October.
