晚熟栽培的番茄、黄瓜着花性不稳定,育苗后期易发生徒长,苗质较差,严重影响产量。为此,对接触刺激和振动刺激防止幼苗徒长进行了实验。这种刺激处理,可促进内生乙烯的产生,进而抑制茎叶生长和节间伸长。接触处理是将布片固定于长1m的细竹上,每天上午9时和下午1时对叶面包括顶芽作4～5次接触刺激(轻抚)。振动刺激是采用家用电扇,距苗2m左右,使电扇摇头送风1分
Late-maturing cultivated tomatoes, cucumber with floral instability, susceptible to late growth nurturing leggy, poor quality, seriously affecting the yield. To this end, contact stimulation and vibration stimulation to prevent the growth of seedling experiments. This stimulation treatment, can promote the production of endogenous ethylene, thereby inhibiting stem and leaf growth and internodal elongation. The contact treatment is to fix the piece of cloth to the fine bamboo with a length of 1m, and make 4 ~ 5 times of contact stimulation (stroking) on the foliage including the top bud at 9:00 am and 1:00 pm every day. Vibration stimulation is the use of household fans, seedlings from about 2m, the fans shook his head air supply 1 point
