收获时间与方式对黔油早2号产量及品质性状的影响

Effects of Different Harvest Time and Mode on Yield and Quality Character of Qianyouzao 2

为探明不同收获时间与方式对黔油早2号产量及品质性状的影响,采用同一单株分别按一段式和两段式脱粒的方法进行试验,对比分析不同收获时间一段式和两段式脱粒油菜籽的水分含量、千粒重和含油量等产量及品质相关性状。结果表明:不同收获时间与方式对黔油早2号商品油菜籽成熟度、水分含量、含油量和千粒重等均有一定的影响;提早收获,油菜籽成熟度低,水分含量高,含油量低,千粒重低;两段式收获较一段式收获含油量高,千粒重高;黔油早2号采用一段式收获宜在成熟度为90%以上时选择晴天进行,两段式收获宜在成熟度达85%以上时选择晴天进行,并在晾晒后熟后及时脱粒。

In order to explore the influence of different harvest time and mode on yield and quality of Qianyouzao 2,one stage threshed and two stage threshed methods were used on the same plant.The yield and quality character and moisture content,thousand kernels weight and oil content were compared as well.Results：Different harvest time and mode had effects on seed maturity,moisture content,oil content and thousand kernels weight.When harvested early,seeds had low maturity,high moisture content,low oil content,low weight of 1 000 seeds.Oil content and weight of 1 000 seeds by two stage threshed were higher than one stage threshed.The suitable harvest maturity for Qianyouzao 2is above 90% when one stage harvest mode is used,reaching more than 85% when two stage harvest mode is used.
