定西地区露地莴笋品种比较试验

近年来,定西地区莴笋的种植面积不断扩大,但长期以来种植品种单一导致莴笋的产量较低。为筛选出适宜当地种植的高产优质莴笋品种,试验引进了5个莴笋品种进行露地栽培比较试验。结果表明,青笋独霸三夏和状元红大田栽培综合性状较优,产量较高,分别为5670.2 kg/667 m^2和4402.5 kg/667 m^2,且病情指数较低,分别为2.37%和2.08%,适合进行露地推广种植。闽皇一号、锄头牌红莴笋综合性状表现较差、抗病性较差,且产量较小,不适合在当地露地推广种植。

Comparison Experiment of Lettuce Varieties in Open-field in Dingxi Area

In recent years,the planting area of lettuce in Dingxi area has been expanding,but for a long time,the yield of lettuce is low because of the single variety.In order to screen out the high-yield and high-quality lettuce varieties suitable for local cultivation,five lettuce varieties were introduced for open-field cultivar comparison experiments.The results showed that the comprehensive characters of the field cultivation of"Qingsun Dubasanxia"and"Zhuangyuanhong"were better,the yield was higher,which were 5670.2 kg/667 m^2 and 4402.5 kg/667 m^2 respectively,and the disease index was lower,which were 2.37%and 2.08%respectively.These two varieties could be suitable for the local open field cultivation.The comprehensive characters of"Minhuangyihao"and"Chutoupai Hongwosun"were weak,disease resistance was poor,and the yield was small,which was not suitable for local open field promotion.
