hinese scientists have successfully grown peanuts in Northwest China's high-altitude Qinghai province for the first time, local authorities said.

据地方当局透露，中国科学家首次在中国西北部高海拔的青海省成功种植了花生。

In a demonstrative project hosted by the Qinghai Academy of Agriculture and Foresty Sciences, researchers have been conducting trial planting of several crops including ginger¹ and peanuts since March. Five peanut varieties were tested to pick out the best.

在青海省农林科学院主办的一项示范项目中，研究人员从今年3月以来一直在试验种植姜和花生等几种作物，对5个花生品种进行试验以选出其中最好的。

"The peanuts are growing well with few diseases and pests, which proves that peanut planting is possible in greenhouses on the Qinghai plateau," said Huang Pingui, deputy-director with husbandry and poverty relief and development bureau of Huangzhong County.

湟中县农牧和扶贫开发科技局副局长黄品贵表示：“花生长得很好，病虫害少，这证明了在青海高原的温室里种植花生是可行的。”

"The yield per plant is expected to be between 220 and 350 grams, making the peanut yield per mu (about 0.07 hectares) reach at least 500 kilograms," Huang added.

黄品贵补充称：“每株花生的产量预计在220克到350克之间，使每亩（约0.07公顷）花生的产量至少达到500公斤。”

As a warm-weather plant, peanuts usually require a long, hot growing season and loose sandy soil to develop in.

作为一种适合在温暖的气候下生长的植物，花生通常需要一个漫长、炎热的生长季节，以及疏松的沙土环境。

The trial success of peanut planting marks a breakthrough in agriculture in the barren land of Qinghai province.

花生种植试验的成功标志着青海省贫瘠土地农业的突破。

It offers the farmers another option in greenhouse vegetable planting, and optimizes² the structure of the vegetable industry in the region, the local official said.

当地官员表示，这为农民提供了温室蔬菜种植的另一种选择，并优化了该地区蔬菜产业的结构。
