番茄是人们喜食的蔬莱,上海邵区每年栽培春番茄3万亩左右。春番茄苗期处于1～2月份低温期,低温影响秧苗正常生长,特别是春番茄的花芽分化和花器发育,造成许多畸形果(老虎脚爪)。近年来,全市春番茄第一塔果的畸形果发生率达20～40%,严重的田块在50%以上,畸形果的产量占番茄产量的10～20%,每年因畸形果损失的番茄约7500～10000吨。因此,这个问题引起了科研和生产部门的重视。1987年4～7月,我们在川沙县六里
Tomatoes are people who eat vegetables, Shanghai Shao District, annual cultivation of about 30,000 acres of tomato. Spring tomato seedling stage is in the low temperature period from January to February, low temperature affects the normal growth of seedling, especially flower bud differentiation and floral development of spring tomato, resulting in many deformed fruit (tiger foot paw). In recent years, the first tower of the city’s spring tomato fruit deformity incidence of 20 to 40%, more than 50% of the serious plots, the production of deformed fruit accounted for 10 to 20% of tomato production, the annual loss of deformed fruit tomato About 7500 ~ 10000 tons. Therefore, this issue has aroused the attention of research and production departments. From April to July 1987, we were in Liuli, Chuansha County
