通过几年的摸索和实践,总结出大棚番茄-夏丝瓜、小青菜-秋延莴笋栽培模式,并在全县推广应用,有效地提高单位面积的产量和经济效益。 1 茬口安排大棚番茄于12月下旬播种育苗,翌年6月下旬采收结束; 夏丝瓜于3月下旬用营养钵育苗,5月中旬定植番茄畦两边,9 月中旬采收结束;秋延后莴笋9月上中旬育苗,11月初定植, 至春前采收结束。 2 栽培技术 2．1 大棚番茄 2．1．1 品种选择。选择耐寒、抗病、品质优、产量高的品种。如ID204、中杂9号等。 2．1．2 培育壮苗。12月下旬,将选好的种子放入55℃温水中浸泡15min后浸种3-5h,让种子充分吸足水分后,放入30℃左右的恒温箱中催芽1-2d后,均匀撒播在准备好铺有电热线的苗床上覆土0．5cm,每平方米苗床播6-8g种子,进行3膜 1帘(地膜、中棚膜、大棚膜、草帘)覆盖育苗,温度白天控制
After several years of exploration and practice, summed up the greenhouse tomato - summer loofah, small green vegetables - autumn lettuce cultivation mode, and promote the use of the county, effectively raising the yield per unit area and economic benefits. 1 stubble arrangement shed tomato in late December seeding nursery, the end of June harvest the end of the following year; summer loofah in late March nursery bowl, mid-May planting tomato on both sides, mid-September end of harvest; late autumn lettuce Seeding in mid-September on September, early November planting, harvesting to spring before the end. 2 cultivation techniques 2.1 greenhouse tomato 2.1.1 species selection. Choose cold, disease resistance, excellent quality, high yield varieties. Such as ID204, miscellaneous 9 and so on. 2.1.2 Cultivate strong seedlings. In late December, the selected seeds are soaked in warm water at 55 ℃ for 15min and soaked for 3-5h so that the seeds fully absorb the water and then put into the incubator at about 30 ℃ for 1-2d, and then evenly spread in preparation Well covered with electric hotline seedbed bed soil over 0.5cm, 6-8g seed per square meter seedbed seedbed, 3 film 1 curtain (film, in greenhouse film, greenhouse film, straw curtain) cover nursery temperature control during the day
