不同水分用量对小香葱生长的影响

The Effect of Different Amounts of Water on the Growth of Allium schoenoprosum L.

为探明小香葱生长对水分的需求规律,采用盆栽法研究不同水分处理对小香葱生长的影响。结果表明,水分对小香葱的部分性状及产量影响显著,随着浇水量的增加,株高、株幅、假茎横径、单株叶数、分蘖数、根数、根长、地上部鲜重及地下部鲜重均逐渐增加而后下降,以1kg烘干土壤每次浇水700 mL的小香葱生长势较好,产量最高,较其他处理增产92.92%~537.43%,折合土壤含水量为70%时,增产效果显著。

In order to investigate the effect of water amount for growth of Allium schoenoprosum L.,using the method of potted control water,growing influence of different water treatments were studied in this paper.The results showed that water had a significant influence on the yield and some character of A.schoenoprosum L.The plant height,plant width,pseudostem transverse stem,leaf number per plant,tiller number,root number,root length,fresh weight in overground part and fresh weight in underground part increased and then decreased with the increase of watering amount.When the water amount was 700ml per 1kg of drying soil at a time,the growth and yield of A.schoenoprosum L.were the best.Compared with other treatmeats the increase was 92.92%~537.43% in yield.Therefore,it was recommended that the soil moisture content of the daily field management for the production of A.schoenoprosum L.should be 70%.
