摘要
以盐丰47为供试材料,研究比空栽培不同株距对水稻产量及品质的影响。结果表明,比空栽培有利于促进水稻成穗率的提高和稻米外观品质的改善。比空栽培模式下,成穗率2 a平均值最高可达到90.8%,垩白粒率和垩白度降低。株距在14 cm时,比空栽培模式既能获得较高的产量,同时稻米外观品质较好。
Yanfeng-47 was used as the experimental material to study the effects of different plant spacing on rice yield and quality.The results showed that the specific space cultivation was beneficial to the improvement of rice heading rate and rice appearance quality.The average heading rate of 2 a was up to 90.8%,and the chalkiness grain rate and chalkiness degree were decreased.When the plant spacing was 14 cm,the rice yield was higher and the appearance quality was better.
