和田地处塔里木盆地南缘,喀喇昆仑山北麓,气候炎热干旱,积温高,光照强,降雨量少,蒸发量极大,灌溉条件良好,这种优越的生态环境很适合西瓜栽培。然而,生产上沿用的当地品种比较混杂,栽培管理粗放,成熟偏晚,品质较差,致使西瓜产量产值很低。笔者1982—1983年进行早熟丰产栽培的试 Hotan is located in the southern margin of the Tarim Basin and the northern foot of the Karakorum Mountains, with hot and dry climates, high accumulated temperature, strong light intensity, low rainfall, great evaporation and good irrigation conditions.
