摘要：

引进合适品种在当地推广种植,可促进地区农民增收,农业发展。以海南绿川种苗有限公司最新育成的美玉加甜糯25号对研究对象,并以美玉7号为对照,开展播期和种植密度试验。研究结果表明,春播播期越迟,生育期越短;夏播播期越晚,生育期越长,种植密度对生育期的影响不明显。方差分析结果表明,美玉加甜糯25号产量显著高于美玉7号(P<0.05)。不同播期之间产量差异、不同种植密度之间产量差异分别达到显著水平(P<0.05)和极显著水平(P<0.01)。其中每667 m2 4 200株种植密度下平均产量最高,7月20日播期平均产量最高。品种、播期和种植密度均对外观品质产生显著或极显著影响,其中,4月5日播期和每667 m2 2 800株种植密度下外观品质评分最高。美玉加甜糯25号蒸煮品质显著高于美玉7号(P<0.05)。不同播期蒸煮品质差异极显著(P<0.01),其中4月5日播期蒸煮品质评分最高,但不同种植密度间蒸煮品质差异不明显。美玉加甜糯25号较美玉7号品质总分高2.2分,其品质总分差异达到极显著水平(P<0.01)。不同播期品质总分差异达到了极显著水平(P<0.01),其中4月5日播期品质总评分最高。不同种植密度品质总分差异达到了极显著水平(P<0.01),其中每667 m2 2 800株种植密度下品质总分最高。并且品种与播期互作、种植密度与播期互作导致的品质总分差异均达到极显著水平(P<0.01)。

Abstract:

Introducing suitable varieties for local promotion and cultivation, can promote increased income for local farmers and agricultural development. The latest Meiyu Jia Tiannuo 25 developed by Hainan Lvchuan Seedling Co., Ltd. was used as the research object, and Meiyu 7 was used as the control to conduct sowing time and planting density experiments. The results indicated that the later the spring sowing period, the shorter the growth period; the later the summer sowing period, the longer the growth period, and the effect of planting density on the growth period was not significant. The results of variance analysis showed that the yield of Meiyu Jia Tiannuo 25 was significantly higher than that of Meiyu 7 (P<0.05). The yield differences between different sowing dates and planting densities reached significant levels (P<0.05) and extremely significant levels (P<0.01), respectively. The average yield was highest at a planting density of 4 200 plants per 667 m2, and the average yield was highest during the sowing period on July 20th. Variety, sowing time, and planting density all had a significant or extremely significant impact on appearance quality, with the highest appearance quality score observed on April 5th during the sowing period and at a planting density of 2 800 plants per 667 m2. The cooking quality of Meiyu Jia Tiannuo 25 was significantly higher than that of Meiyu 7 (P<0.05). There was the extremely significant difference in cooking quality among different sowing dates (P<0.01), with the highest cooking quality score observed on April 5th. However, there was no significant difference in cooking quality among different planting densities. The quality total score of Meiyu Jia Tiannuo 25 was 2.2 points higher than that of Meiyu 7, and the difference in quality total score was extremely significant (P<0.01). The difference in quality total scores among different sowing dates was extremely significant (P<0.01), with the highest quality total score observed on April 5th. The difference in quality total scores among different planting densities reached a extremely significant level (P<0.01), with the highest quality total score at a planting density of 2 800 plants per 667 m2. And the differences in quality total scores caused by the interaction between varieties and sowing dates, as well as the interaction between planting density and sowing dates, all reached the extremely significant level (P<0.01).
