Effects of seedling tray specifications on the growth and development of tobacco seedlings
摘要
Abstract
To investigate the effects of different seedling tray specifications on tobacco seedling quality,a shallow-water tray seedling nursery system was adopted,and three tray specifications were established:128-cell(TP1),98-cell(TP2),and 72-cell(TP3).The agronomic traits,dry matter accumulation,and nutrient uptake of tobacco seedlings were compared across treatments.The results showed that tray specifications had little effect on the emergence rate.At 40 days after sowing,as the cell number per tray decreased,the leaf fresh and dry weight per plant,root growth and development indicators,and N,P,and K accumulation per plant all showed increasing trends.At the transplanting stage,the stem dry weight and fresh weight of seedlings in the TP2 and TP3 treatments were higher than those in the TP1 treatment.At 30 days after transplanting to the field,the maximum leaf area was highest in the TP2 treatment,reaching 1 041.98 cm2.In terms of seedling production cost,the TP1 treatment produced a greater number of seedlings,consumed less substrate,and had a relatively lower cost,while the TP3 treatment had the highest cost at 34.22 yuan/667 m2.In summary,while ensuring a certain level of seedling quality and considering the actual production cost of flue-cured tobacco,the 98-cell tray(TP2)is recommended for practical application.关键词
