- 摘要:
- 以3年生非均匀密度种植的香椿为试材，采用L9(34)正交设计进行施肥、浇水和截干试验，研究3因素对香椿萌芽生长和芽菜产量的影响。结果表明：试验实施7 d时，香椿开始萌发幼芽，其平均萌芽数和成枝数分别是4.1～7.7芽/株和1.4～2.2枝/株；50、70 d时，香椿芽直径和芽长分别为2.8～4.0 mm、3.5～8.3 cm和2.9～4.2 mm、4.0～9.0 cm。试验实施的70 d内分2次采摘芽菜，其总产量及其产值分别达661.3～3 161.8 kg/hm2和13 225.2～63 236.0元/hm2。处理组合间，萌芽生长和芽菜产量具有显著或极显著的差异影响，有机肥是影响此二指标的关键因子。芽菜产量最高的处理组合是每株施有机肥0.25 kg，定干高20 cm和每4 d浇水1次。
- Abstract:
- The 3-year-old Toona sinensis, which was planted by regime of uneven row spacing，was served as experimental materials to trail the experiment of the fertilization with watering control and cutting-stem effect of these three factors on the sprouting and its vegetable output of Toona sinensis under applied the L9(34) orthogonal design.The results showed that it was beginning sprouting after 7 days of implemented the trail with mean sprouts of 4.1-7.7 and branches of 1.4-2.2 per stem，respectively.There were 2.8-4.0 mm，3.5-8.3 cm and 2.9-4.2 mm，4.0-9.0 cm of sprouting diameters and lengths of T.sinesis，respectively，after trail implemented for 50 days and 70 days.For 70 days of the experiment carried out，total output and value of sprouting vegetable were 661.3-3 161.8 kg/hm2 and 13 225.2-63 236.0 RMB/hm2，respectively.It was presented significant differences of sprout growth and sprouting vegetable yields between treatment combinations with pivotal factor of organic fertilizer influencing these two parameters.The optimal treatment combination of the highest sprouting vegetable yield was organic fertilizer 0.25 kg/stem with 20 cm cutting-stem and watering once every 4 days.
