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(T_1)、8月30日(T_2)、9月9日(T_3),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,667m~2产量达2 014.8kg,分别比8月30日、9月9日播种增产23.6%和53.7%,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53d,采收期持续32d;而8月30日、9月9日播种从播种到采收分别需要63、65d,采收期持续24、13d;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。
The average sowing date of autumn melon planting in Nanning city of Guangxi was used as the normal sowing date (CK), and the sowing dates of the melon varieties “Sweet fairy 1” The effects of different planting stages on the growth and development characteristics of Chieh-qua and their yield were studied on August 20 (T_1), August 30 (T_2) and September 9 (T_3). The results showed that the effects of different sowing dates on the yield were significant. The sowing yield was the highest on August 20, and the yield of 667m ~ 2 reached 2 014.8kg, which was 23.6% and 53.7% more than that of sowing on August 30 and September 9 respectively The quality of single melon was also significantly higher than the late sowing; within a certain time range, the earlier the sowing period, the shorter the growing period of the cutwort, the longer the harvesting time; the sowing on August 20 only required 53 days from sowing to harvesting The harvest period lasted 32d; and the seeding on August 30 and September 9 took 63 and 65 days respectively from sowing to harvesting, and the harvesting period lasts for 24 and 13 days. The experiment showed that the optimum sowing date for postponement cultivation of autumn melon was 8 On the 20th of the month, while on the 30th of August and 9th of September the sowing, slow growth and development, the output decreased obviously. Therefore, the autumn melon autumn cultivation should be properly early sowing.
