莴笋又名莴苣,是人们喜爱的蔬菜品种之一。为调节蔬菜淡季供应,近年射阳县合德镇菜农倪宏摸索出一套夏栽莴笋高产栽培新技术,连续多年667平方米产量突破1200千克,产值2000元,经济效益十分显著。这一新技术的具体作法是: 1.低温催芽 夏莴笋生长期正值高温季节,故必须选用耐热、不易抽薹、抗病、商品性好的中晚熟“山阳1号”“白皮2号”等优质高产良种。播前先催芽,用冷水浸种8～12小时,待种子吸水率达70％～80％时,用湿纱布包好,置于冰箱冷藏室或悬挂在水井离水面10
Lettuce, also known as lettuce, is one of the favorite vegetable varieties. In order to regulate the off-season supply of vegetables, in recent years, Nihong, a vegetable farmer in Hede Town, Sheyang County, came up with a set of new high-yielding cultivation techniques for summer lettuce. The output of 667 square meters for many years exceeded 1200 kg and the output value was 2,000 yuan. The economic benefits are very significant. The specific practices of this new technology are: 1. Low temperature sprouting summer lettuce growing season is hot season, it must be heat-resistant, not easy to bolting, disease resistance, good commercial and middle-aged “Sanyo 1” “White 2 No. ”and other high-quality varieties of high yield. Sowing before germination, with cold soaking 8 to 12 hours until the seeds of water up to 70% ~ 80%, wrapped with a wet gauze, placed in the refrigerator freezer or hanging in the well from the water 10
