中华猕猴桃果实生长发育的研究

Study on the Growth and Development of Actinidia chinensis Plamch

以8～9a生79—2和秦美2个猕猴桃品种为材料，研究其果实生长发育动态。结果表明：2个品种果实的生长量在年生长发育过程中出现2次高峰期，79—2品种分别出现在5月20日到6月23日和6月16日到8月18日；秦关品种分别出现在5月20日到6月30日和6月30日到8月11日；2个品种果实的净增长量在年生长发育过程中均出现3次生长高峰，79-2品种出现时间，第1次，果实纵径、宽横径和厚横径同时在5月27日，第2次，果实纵径和厚横径都集中在6月9日，而宽横径在7月14日，第3次，果实纵径在6月23日，宽横径在8月11日，厚横径在7月7日；秦美品种出现时间，第1次，果实纵径、宽横径和厚横径都同时在5月27日；第2次，果实纵径在6月23日，宽横径和厚横径都集中在6月30日；第3次，果实纵径在8月4日，宽横径和厚横径都同时在8月1日；建议在该地区条件下施壮果肥的时期要求在5月中旬为最佳，同时要求在各个需肥期加强根外追肥243次，效果更好。

Taking 8 to 9 years 79-2 species such as materials, the two kiwi fruit growth dynamics were studied. The resuits showed that the two varieties of fruit in the growth of the growth process two peak periods, 79-2 varieties respectively on May 20th June 23, June 16, and until August 18, Qin varieties of beauty in May 20 to 30 June 30 June and August 11 ;two fruit varieties of net growth in annual growth process are three growth peak, 79-2 varieties, the first time, the longitudinal diameter, fruit width width and thickness and width on May 27, the second longitudinal diameter and thickness, fruit width was focused on June 9, and wide width on July 14, third, longitudinal diameter fruit in June 23, wide width on August 11, thicker width on July 7, Qin beauty, the first time varieties of longitudinal diameter, fruit, wide width and thickness and width are on May 27, The second longitudinal diameter, fruit on June 2a, wide width and thickness width is focused on June 30, Third, the fruit of longitudinal diameter on August 4, wide width and thickness and width are concentrated on August 1;advice in this area conditions among fruit weight period required for the best in mid--may, requiring fertilizer requirement in each period of strengthening the root according to 2 ~ 3 times, the effect is better.
