摘要： 旨在探明不同播期对‘越光’生长发育及其产量的影响，确立‘越光’在黄淮区域作麦茬夏稻栽培的适宜播期，阐明‘越光’适期播种高产的生长发育特点。以‘越光’为试验材料，连续进行了2年的田间试验，2013年设T1（5月1日）、T2（5月11日）、T3（5月21日）、T4（5月31日）4个播期处理，6月27日移栽，2014年与2013年播期处理相同，6月30日移栽，随机区组设计，3次重复。2013年的试验结果表明，T3（5月21日播种，秧龄37天）产量最高，为6681.8 kg/hm2，T4（5月31日播种，秧龄27天）产量次之，为 6533.2 kg/hm2，两者之间差异不显著；2014年的试验结果表明，T′3（5月21日播种，秧龄40天）产量最高，为6866.4 kg/hm2，T′4（5月31日播种，秧龄30天）产量次之，为6647.4 kg/hm2，两者之间差异不显著。2年试验中均以5月21日播种的综合农艺性状最好，5月31日播种的次之，表现为分蘖集中、蘖位较低，一次大分蘖所占比例大，群体整齐，后期不早衰，抗倒伏能力强，灌浆成熟期延长，落黄好，产量高，品质好。试验得出的结论是：‘越光’在黄淮区域作麦茬夏稻栽培适宜播期为5月下旬，适宜秧龄为35天左右（6叶1心），10月1日前后成熟，全生育期127天左右；适当晚播是避免早衰、防止倒伏、提高单产的关键技术措施。

Abstract: In order to find the suitable sowing date and its high-yield growing characters, the effect of different sowing dates on the growing development and yield of koshihikari under the condition of cultivation after wheat in Huanghuai Area was researched. Two year’s field experiments were carried out with a randomized block design and three replications using the material of Koshihikari. There were four treatments of sowing date in 2013: T1 (May 1st), T2 (May 11th), T3 (May 21st) and T4 (May 31st), and the transplanting was on June 27th. The same treatments of sowing date were designed in 2014 and the transplanting was on June 30th. The result of 2013 showed that the difference of yield between T3 and T4 was not significant: T3 was the highest: 6681.8 kg/hm2 (sown on May 21st, 37 days of seedling age), T4 was the second: 6533.2 kg/hm2 (sown on May 31st, 27 days of seedling age). The result of 2014 showed that the difference of yield between T′3 and T′4 was not significant: the yield of T′3 was the highest: 6866.4 kg/hm2 (sown on May 21st, 40 days of seedling age). The second was T′4: 6647.4 kg/hm2 (sown on May 31st, 30 days of seedling age). By two years’ experiments, the composite agronomic-traits of sowing on May 21st were proved to be the best, that of sowing on May 31st were the second, showing concentrated tillering, low tiller position, high percentage of the first tillers, trim population growing, no early senility in the later-period growth, resisting to lodging, good color of maturity and high yield. The results showed that the suitable sowing date of koshihikari was in the late of May for summer rice after wheat in Huanghuai Area. Its whole growing period was 127 days and its available seedling age was about 35 days (6-7 leaves) and it matured on about Oct.1st. Delaying the sowing date appropriately was the key measure of avoiding early senility and lodging and increasing the yield.
