早春保护地栽培番茄,常由于低温弱光照影响子房和花粉发育造成落花落果,经济效益不高。为探索番茄灵在早春番茄上的使用技术及效果,1996～1997年设置了不同浓度的番茄灵比较试验。试验采用上海试剂四厂生产的番茄灵。供试品种为当地大面积种植的L-402番茄。采用随机区组排列,重复3次,每小区3垄,每垄50株。1月上旬在冬暖大棚内播种育苗,3月上旬定植于冬暖大棚,行株距为50cm×39cm。从初花期进行不同处理,上午9～10时
Tomato cultivation in early spring protected areas, often due to low temperature and low light affect ovary and pollen development caused by falling flowers, economic efficiency is not high. In order to explore the technology and effect of Tomato Ling on the tomato in early spring, different concentrations of Tomato Ling were set up from 1996 to 1997. Test using Shanghai Reagent Factory production of tomato Ling. The test varieties for the local large-scale cultivation of L-402 tomato. Using random block arrangement, repeated 3 times, each ridge 3 ridge, 50 per ridge. In early January in winter warm shed sowing nursery, early March planting in winter warm greenhouse, line spacing is 50cm × 39cm. From the beginning of flowering for different treatment, 9 am to 10 am
