- 摘要:
- 以节瓜品种“甜仙子1号”为试材，以广西南宁秋季种植节瓜的平均播种期为常规播种期（CK)，在常规播种期前后进行分期播种，设3个处理，分别为8月20日（T1)、8月30日（T2)、9月9日（T3)，探究节瓜在秋季延后栽培中，不同播种时期对节瓜生长发育特性及产量的影响。结果表明：不同播种期对产量影响有显著差异，8月20日播种产量最高，667 m2产量达2 0148 kg，分别比8月30日、9月9日播种增产236%和537%，且单瓜质量也显著高于后期播种；在一定时间范围内，播种期越早，节瓜的生育期越短，采收期越长；8月20日播种从播种到采收仅需要53 d，采收期持续32 d；而8月30日、9月9日播种从播种到采收分别需要63、65 d，采收期持续24、13 d；试验表明，节瓜秋季延后栽培最适播种期为8月20日，而8月30日、9月9日播种，生长发育缓慢，产量明显下降。因此，节瓜秋季延后栽培要适当的早播。
- Abstract:
- ‘Tianxianzi No1’chieh-qua was used as material，used average time of planting chieh-qua in autumn as conventional seeding time(CK)，seeding before or behind it，the experiment set three treatments in seeding time，they were August 20(T1)，August 30(T2) and September 9(T3)，respectively，in order to study different sowing dates had effects on production and reproductive characteristics of chieh-qua in autumn-prolonging cultivation.The results showed that different sowing time had significant difference in yield，and the production of T1 was the heaviest，its yield came up to 2 0148 kg per 667 m2.The yield increased by 236% and 537% compared with T2 and T3，and single fruit weight was also significantly higher than that of the late sowing.Within a certain time range，the earlier sowing time was，the shorter growth period and the longer harvest time had.The time of sowing to harvesting needed 53 days in T1.Harvest time lasted 32 days；T2 and T3 were 63 days and 65 days，respectively.Harvest time of T2 and T3 last 24 days and 13 days.The experiment showed that T1 was the best time for production and reproductive characteristics of chieh-qua in autumn-prolonging cultivation.It showed that growth development and production were delayed in T2 and T3 compared with T1.Therefore，the appropriate early sowing was appropriate in autumn-prolonging cultivation of chieh-qua．
