Abstract：In order to evaluate the effects of different growth years on biomass and chemical composition of Notopterygium forbesii under artificial cultivation， the investigation and sampling of broad-leaf of Notopterygium forbesi in main producing areas of Gansu Province were carried out. The Notopterygium forbesii were cultivated for two years and three years， then the excavation of fresh Notopterygium forbesii of two years and three years were measured its root fresh weight， root dry weight， root length， root thick four biomass index， and notopterygium alcohol， isoimperatorin， volatile oil， extract， polysaccharide， total ash， and acid insoluble ash. The results showed that the root fresh weight， dry weight， taproot length and crude root of the three-year old increased compared with those of the two-year old， and the total yield of Notopterygium forbesii was 2～3 times of that in two years. The total content of active ingredients in the three year old Notopterygium forbesii was significantly increased， however the content of each active ingredient decreased and the quality was slightly worse.

番茄（Solanum lycopersicum）是以成熟多汁浆果为产品的茄科番茄属草本植物，原产南美，又名西红柿、洋柿子，是我国蔬菜栽种植面积排名第4的蔬菜品种。近年来，番茄在河西走廊地区种植趋势逐渐扩大，形成了露地加工番茄和设施番茄周年生产的栽培模式，番茄产业已成为甘肃蔬菜产业的重要组成部分[1 ]。番茄品种繁多，不同品種的产量和质量受其遗传真实性直接影响[2 ]。温室栽培因其湿度大、不通风，种植时易出现病害，给生产带来很大难题。随着市场需求的变化，番茄品种类型的引进也多种多样，但适应性参差不齐。为筛选出适合本地区种植栽培的番茄品种，我们选取在其他地区种植较广的7个番茄品种，对其丰产性、商品性和抗病性进行比较，旨在筛选出更适宜本地区栽培的戈壁日光温室越冬茬番茄品种。

1.1   试验区概况

酒泉市肃州区东部（北纬39° 44′，东经98° 31′）属于典型的大陆性季风气候。该区降水少，蒸发量大，热量充沛，光照充足，戈壁面积大，地势平坦，是发展戈壁农业的理想区域之一。试验日光温室为全钢架装配型温室，东西走向，跨度10 m、脊高4.9 m，长度80 m，可以满足番茄越冬生产对温光环境的需求。……
