空间电场对日光温室番茄生长发育的影响

摘要

This research mainly studied the space elecuic field's effect on growth environment and plant biology of solar greenhouse tomato.The results showed that using the space electric field technology improved night temperature in cloudy day,reduced the solar greenhouse air relative humidity,and increased the light intensity,could also improve soil fertility to a certain extent,which mainly increased the content of soil available phosphorus.The space electric field technology could also make the soil pH value to be neutral,increase soil actinomyces quantity,could also increase the tomato stem roughness,improve the fruit quality and yield.All results showed that the space electric field technology can change the greenhouse crop growth environment,benefit for crop growth,and increase crop yield.%主要研究了空间电场环境对温室番茄生长环境和植株生物学特性的影响.结果表明,采用空间电场技术可以提高日光温室阴天及夜晚气温,降低空气相对湿度,提高光照强度;可以在一定程度上提高土壤肥力(主要提高了土壤速效磷含量);可以促使土壤pH趋于中性,提高土壤放线菌数量;能够增加番茄茎秆粗度,提高单果质量和单株产量.试验表明,空间电场技术可以改变日光温室作物生长环境,有利于作物生长发育,提高作物的产量.
