摘要: |
为了研究软枣猕猴桃授粉规律,以11年生软枣猕猴桃紫果3号为试验材料,设置剪留花柱数量为0、2、5、8、11、14、17和23(全留对照组)共8个处理。人工授粉,收获后调查测定其单果重、坐果率、果型指数、果实可溶性固形物含量和果实内含种子数量。结果表明:随着授粉柱头数的增加,单果重等主要指标相应增加;当授粉柱头数增至为8时,其果型指数和果实可溶性固形物含量与对照全留柱头23相比差异不明显;当授粉柱头数增至为11时,其单果重、坐果率和果实内含种子数量与对照全留柱头23相比差异不明显。据此软枣猕猴桃充分授粉的数量级指标为11,当授粉柱头数小于11时,产量降低、品质下降;当授粉柱头大于11时,浪费花粉。生产上可利用猕猴桃精准充分授粉技术,节约使用花粉或减少果园雄株数量,以提高生产效率。 |

Abstract: |
In order to study the pollination rule of Actinidia argute, we took 11 years old Actinidia argute purple fruit No.3 as materials, and set 8 treatment groups (0,2,5,8,11,14,17,23) according to the number of reserved pollinated stigmas. All of them were artificially pollinated. Some indexes were measured after harvest, including fruit setting rate, single fruit weight, fruit shape, fruit soluble solid contents and the seed number. The results showed that with the increase of pollination stigma number, the main indexes increased accordingly. When the pollination stigmas were 8, fruit shape and fruit soluble solids contents had no significant difference with control group (the pollination stigmas were 23). When the most number of stigmas reserved was 11, the indicators of fruit setting rate, single fruit weight, and the seed number had no difference in indexes compared with the control group (the pollination stigmas were 23). When pollinated stigma number was less than 11, yield reduced and quality declined. When the pollination stigmas were more than 11, pollens were wasted. So the order of magnitude index for fully pollination of Actinidia argute is 11. Accurate and sufficient pollination technology can be used in production to save the use of pollen or reduce the number of male orchard plants to improve the production efficiency. |
