近年来,随着保护地栽培技术不断改进和提高。在塑料大棚中种植秋番茄的面积也不断增加。既改善了市场对番茄的要求,又提高了塑料大棚的利用率。然而,秋番茄是夏播、秋收,生长前期高温多雨、病、虫为害严重,种植技术难度较大,生长后期,气温下降,大部果实只达到绿熟程度,需要进行贮藏保鲜,促其后熟才能提高经济价值。笔者根据几年的实际观测,就大棚秋番茄的生产,谈几点看法,供参考。一品种选择大棚秋番茄在7月中旬播种,到11月上旬(立冬前)棚内出现临界低温时而被迫拉秧,有效生育期能达110天。此间80％以上的青果能得到充实发育,经贮藏后熟能分期应市。为此,在选用
In recent years, as the cultivation techniques of protected areas continue to improve and improve. In the plastic shed planting autumn tomato area also continues to increase. Not only improve the market demand for tomatoes, but also improve the utilization of plastic greenhouses. However, the Autumn Tomato is a summer sowing, autumn harvest, the early growth of high temperature and rainy, disease, insect serious damage, planting more difficult, late growth, temperature drops, most of the fruits only reach the green level, the need for storage, Cook to improve economic value. According to a few years of the actual observation, the author of the autumn tomato production in the shed, talk a few comments for reference. Autumn selection of a variety of autumn greenhouse tomato planting in mid-July, early November (pre-winter) shed critical low temperature and sometimes forced La Yang, effective growth period of up to 110 days. Here more than 80% of green fruit can be fully developed, after storage, cooked should be staged. To this end, the choice
