摘要
为验证利凉的应用效果,采用大田试验方法,研究利凉处理下大棚环境、秋番茄生长、结果和茎基腐病的状况。结果表明:在晴天和阴天条件下,利凉处理棚膜均起到降低大棚内的地温、气温和光照强度的作用,同时可提高大棚内的空气相对湿度,为秋番茄生长提供良好的环境条件。与对照大棚相比,利凉处理大棚提高了秋番茄植株的生长速率,可使秋番茄第一花序坐果率提高18.51%,第一层果实产量提高82.66%,同时可降低大棚秋番茄茎基腐病的发病率达15.28%。综上,利凉可以在大棚秋番茄生产上应用。
The paper aims to verify the application effect of sombrasol on greenhouse environment and the growth,fruiting and basal stem rot of autumn tomato by field experiments.The results showed that:under sunny and cloudy conditions,the greenhouse film with sombrasol treatment could reduce the ground temperature,air temperature and light intensity and improve the relative air humidity,and provide a good environmental condition for the growth of autumn tomato;compared with the control treatment,sombrasol treatment improved the growth rate of autumn tomato plants,increased the fruit setting rate of the first inflorescence by 18.51%and the yield of the first layer fruits by 82.66%,and reduced the incidence of basal stem rot by 15.28%.In conclusion,sombrasol can be applied to autumn tomato production in greenhouse.
