早熟高粱夏播的研究指出，我们选育的高粱杂交种６２３Ａ／１７３８春播时（４月３０日播种）出苗至成熟１１５天，夏播（６月中旬播种）则不足１００天。夏播缩短生育期主要是出苗至拔节期的日数减少了。夏播高粱旺盛生长发育的拔节至开花期正逢７月中旬至８月中旬的高温多雨天气，高粱的喜温和大量的水分需要得到了满足，植株生长健壮，有大的叶面积指数和高的光能利用率，从而产生较春播还高的产量，６２３Ａ／１７３８一般亩产５００公斤以上。省级现场验收指出，这个杂交种为套复种增添了一个新的下茬作物，填补了我省高粱套复种的空白，同时又是春旱晚播夺丰收的救灾品种，有广泛应用前景。
Early maturing sorghum summer sowing research pointed out that we bred sorghum hybrid 623A / 1738 spring sowing (April 30 sowing) emergence to maturity 115 days, summer sowing (sowing in mid-June) is less than 100 days. Summer sowing shortened growth period is mainly the number of days from emergence to jointing reduced. Summer sowing sorghum vigorous growth and development of the jointing to flowering period coincides with the hot and rainy weather from mid-July to mid-August, the sorghum’s warmth and a large amount of water needs to be met, plants grow robust, with large leaf area index and high Light energy utilization, resulting in higher than the spring sowing output, 623A / 1738 generally more than 500 kilograms per mu. Provincial-level inspection and acceptance indicated that this hybrid seedling added a new crop under the set crop and filled up the blank of sorghum seedling multiplication in our province, meanwhile, it is also a disaster relief species that is harvested in the spring and evening harvest and has wide application prospects.
