对秋作番茄紗网育苗与露地育苗进行了对比研究,包括紗刚育苗控制病毒病的作用及其对番茄生长、生理特性和产量等的影响。结果表明:①紗网育苗,育苗期行以防止蚜传病毒,控制了幼苗病毒病的发生。幼苗定植后,紗网苗病毒病发生轻,病指数显著降低。②紗网出生长健壮,成苗率提高。③紗网苗定植后生长势强,植株光合强度、叶绿素含量、蒸騰强度都高于露地苗,而呼吸强度、气孔阻力則较低,总产量提高58.5～208.3%。④紗网苗的适宜播期为7月10日,这比一般露地苗期提早20天左右。
The comparative study on the autumn tomato seedling and open field seedling cultivation, including the role of fresh seedling control virus disease and its effects on tomato growth, physiological characteristics and yield. The results showed that: ① gauze nursery, seedling stage to prevent the virus transmitted by the aphids, controlling the occurrence of seedling virus disease. After seedling colonization, the SSM virus disease occurred lightly and the disease index decreased significantly. ② gauze growth robust, increased seedling rate. ③ After the seedlings were planted, the seedlings grew vigorously. The photosynthetic intensity, chlorophyll content and transpiration intensity were higher than those of the open field seedlings, while the respiration and stomatal resistances were lower, and the total yield increased 58.5 ~ 208.3%. ④ gauze suitable sowing date for July 10, which is about 20 days earlier than the general field seedling.
