保护地早春栽培番茄2,4-D蘸花研究

STUDY ON DIPPING FLOWER OF TOMATO WITH 2,4-D IN EARLY SPRING IN PROTECTED CULTIVATION

本试验用不同浓度的2,4-D对包头地区早春保护地栽培番茄植株增长高度、叶片数、座果率、畸形果率、单果重的影响进行了研究,结果表明5mg/L^10mg/L 2,4-D能大大提高番茄座果率、单果重,而畸形果率则较低;而15mg/L^25 mg/L 2,4-D虽然也提高了座果率、单果重,但同时畸形果率也大大增加。

Effects of 2,4 - D on the height, the number of leaves, the rate of fructification, the rate of the misshapen fruit, the weight of the single fruit of tomato were studied by dipping tomato＇s flower in early spring in protected cultivation in Baotou. The results showed that dipping tomato＇s flower with the 2,4 - D of 5 ～10mg/L can advance greatly the rate of fructification and weight of the single fruit, while the treatment with the 2,4 -D of 15 ～ 25mg/L made the rate of the misshapen fruit rise, though it also advanced the rate of fructification and the weight of the single fruit.
