【摘要】 研究浸种时间、播种密度和采收时间对苏麻芽苗菜的生长和产量的影响。先进行单因素试验,设5个浸种时间,分别为8、12、16、20、24 h,设5个播种密度,分别为0.15、0.30、0.45、0.60、0.75 kg/m~2,设5个采收时间,为8、10、12、14、16 d,后进行L9(3~3)正交试验。结果表明,苏麻种子浸种20 h,播种密度为0.60 kg/m~2,播种后12 d采收,苏麻芽苗菜的生物产量达到最高,为2.67 kg/m~2,三种因素的影响程度为:播种密度>浸种时间>采收时间。因此,确定苏麻芽苗菜的最佳浸种时间为20 h,播种密度为0.60 kg/m~2,最佳采收时间为播种后12 d。更多还原

【Abstract】 This study investigated the influence of the soaking time,sowing density and harvesting time on growth,yield of Perilla frulescens sprouts. Single factor experiment was carried out first. There are five soaking times in this study: 8,12,16,20,24 h. There are five density gradients designed in the experiment: 0.15,0.30,0.45,0.60,0.75 kg / m2. There are five harvesting times : 8,10,12,14,16 d.Then orthogonal test L9( 33) was carried out. It showed that the Perilla frulescens soaked seed with 24 h and sowing density of 0.60 kg / m2 and Harvesting at the 12 th day sprout’s biological yield was the highest,2.67 kg / m2. The influence degree of the three factors was: sowing density>soaking time>harvesting time. This study shows that the Perilla frulescens soaked seed with24 h,sowing density of 0.60 kg / m2 and at the 12 th day harvested were the best.更多还原
