不同收获期对百合产量的影响研究

The effect of different harvest time on the bulb yield of lily

通过6个不同收获期对粤北百合产量的影响研究,结果说明粤北地区种植的百合开花后地下鳞茎生长迅速,鲜重平均每天增加1.591g,干重增加0.533g,鳞茎直径增加0.0221cm,但是,鳞片数没有增加。7月底百合鳞茎仍在生长,所以粤北百合的最佳收获期为7月底至8月初,即待百合植株地上器官枯死后收获为宜。

In this article, the effect of different harvest time on the bulb yields of lily was studied. It indicated that the bulb of lily plant in the north area of Guangdong province grew rapidly after blossom came out. The fresh weight of lily increased by 1.591 g/d, the dry weight of lily increased by 0.533 g/d, the diameter of the bulb increased by 0.022 1 cm/d. But the number of bulb scales didn't increase. The bulb of lily continued to grow at the end of July. Therefore, the best harvest time was from the end of July to the beginning of August when the organ of lily on the ground dried up.
