摘要
研究了在大棚作物"伊丽莎白"甜瓜、西班牙五彩椒和西班牙"卡依罗"西红柿的生产中施用光合细菌制剂的效果。结果表明:通过根灌和定期叶面喷施光合细菌之后,3种作物的生长势均优于对照组,产量分别增加862.5、10 965和9 712.5 kg/hm2,而且能够提高产品品质。在甜瓜的生产中,光合细菌可部分代替杀菌药物使用,并能使产品提前2 d上市。在大棚作物种植中施用光合细菌具有增加产量、提高品质和降低药残等功效,因而能够明显提高经济效益。
The field experiment was conducted to study the effects of photosynthetic bacteria on plastic house crop such as melon, ornamental pepper and tomato production and calculate the incremental benefit. The results showed that the tested crop grew obviously better than the control after irrigating and spraying treatment. The yield of tested melon, ornamental pepper and tomato increased 862. 5 kg/hm2, 10 965 kg/hm^2 and 9 712.5 kg/hm^2 than that of the control crops, respectively. Moreover, the tested crop could be improved the quality of the fruits. Additionally, in melon production, the tested group could replace pesticide partly and provide the products two days before the control. In conclusion, usage of photo- synthetic bacteria could increase yield, improve quality, reduce pesticide and enhance the economic efficiency.
