利用不同生育期高油大豆品种的收获期试验,来研究收获期对不同生育期高油大豆品种油分及产量的影响。采用分期收获的方法对6个不同生育期高油大豆品种进行处理,利用近红外谷物品质分析仪进行油分分析,DPS数据处理系统进行数据处理。试验表明,收获期对大豆油分含量和产量有显著的影响。从初熟期开始,随着收获期的延迟,各品种油分含量呈先上升后下降有规律的变化趋势,6个品种的油分含量变化幅度为0.37～0.87个百分点,每个品种都有一个最佳的收获时期以获得最高的油分含量,但油分含量变化情况和品种的生育期相关性不大,是由品种本身的遗传特性决定的。播期对产量也有较明显的影响作用,四个生育期相对较长的品种黑农44、垦农19、合丰48号和合丰47号产量变化较大,达到了极显著水平,而两个早熟品种的产量变化较小,不显著,产量变化总体趋势是晚熟品种>中熟品种>早熟品种。不同生育期的高油品种适期收获能获得较高的油分和产量。
The effects of harvest time on the oil content and yield of high oil soybean varieties with different growth stages were studied by using the harvesting period of high oil soybean varieties with different growth periods. The method of staged harvesting was used to treat six high-oil soybean cultivars with different growth stages. Oil analysis was performed by near-infrared grain quality analyzer and DPS data processing system was used for data processing. Tests showed that the harvest of soybean oil content and yield have a significant impact. From the beginning of the ripening period, with the delay of the harvesting period, the oil content of all cultivars increased first and then decreased regularly. The variation range of the oil content of the six cultivars was 0.37 ~ 0.87%, and each cultivar had one of the most Good harvest time to get the highest oil content, but the changes of oil content and the growth of the species is not relevant, is determined by the genetic characteristics of the species itself. Sowing date also had a significant effect on the yield. The yield of the four longer-growing varieties Heinong 44, Ken-nong 19, Hefeng 48 and Hefeng 47 changed greatly, reached the extremely significant level, while two The yield of early-maturing cultivars changed little but not significantly, and the general trend of yield changes was late-maturing varieties> medium maturing varieties> early maturing varieties. The suitable harvest of high oil varieties at different growth stages can achieve higher oil content and yield.
