摘要
[目的]解决膜下烤烟人工开孔破膜费工耗时和破膜不及时导致烟苗素质差、高温高湿蒸死烟苗、烟苗成活率低的问题.[方法]开展了不同开孔位置及大小的白膜对膜下烤烟影响的试验.[结果]中低海拔烟区移栽膜下烤烟使用烟苗正上方中间开孔2 cm白色地膜,移栽至掏苗前14∶00可降低膜内温度4~12 ℃,烟苗成活率提高11.5百分点,烟株早生快发,减轻病害,大田生育期提早5 d,减少人工破膜开口用工7.5个/hm2,产量和产值比对照分别提高418.35 kg/hm2、4 165.65元/hm2,经济效益明显.[结论]中低海拔烟区膜下烤烟移栽使用相邻2株烟苗中间开孔2 cm白色地膜是可行的.
Abstract
[Objective]To solve the problems of artificial rupture of membrane of tobacco consuming a lot of work and low smoke seedling quality, high temperature and wet steaming dead seedling and low seedling survival rate because of no timely timely ruption.[Method]The test of effects of different hole positions and sizes of the film on flue-cured tobacco under the film was conducted.[Result]Using white membrane with 2 cm hole in the middle of two strains of tobacco seedlings in the mid and low altitude region,could reduce the membrane temperature 4-12 ℃ at 14∶00 from transplanting to sticking seedling, tobacco seedling survival rate increased by 11.5 percent points, tobacco plants grow quicker, reduced the disease, advanced the growth period 5 d, reduced employment 7.5 per hectare, improved the yield and output value of 418.35 kg/hm2, 4 165.65 yuan/hm2,respectively, the economic benefit was obvious.[Conclusion]Using white membrane with 2 cm hole in the middle of two strains of tobacco seedlings in the mid and low altitude region is feasible.
