摘要
研究不同播期和移栽密度对水稻产量与品质的影响。以中熟中粳品种徐稻3号为供试材料比较研究不同播期和移栽密度对水稻产量与品质的影响。研究结果表明:淮北地区徐稻3号的适宜播期范围为5月5日—25日、适宜栽插密度为3.33×105穴/hm2,在此条件下可获得适宜穗数和较大的穗型以及较高的产量,且各项稻米品质指标值较好。
Effects of seeding time and cultivation density on grain yield and rice quality in medium-maturing medium japonica-type rice （MMJR） were studied with Xudao3 as materials. The results showed that the rice quality was highly affected by seeding time and planting density. According to safety, high yield and good quality, the proper seeding time of Xudao3 is from 5th May to 25th May, the proper planting density is 3.33× 10^5 caves/hm^2 in Huaibei. These are suitable conditions to get proper panicle number, larger panicle type and higher yield with good rice quality.
