和田专区位于南疆的西南部,南靠喀喇崐仑山脉,北接塔克拉玛干沙漠,海洋气流影响少,因而降雨少,气候干燥。但日照充足,热量丰富,全年无霜期250天,日平均温度大于10℃的积温达4,330℃。每年六月以后,气温稳定,水源充足,利于复播。当地农民习惯于麦收后种植玉米,一年两收,但由于选择品种不当,耕作粗放,复播玉米产量很低,未能充分发挥自然条件的增产潜力。 一九五八年,我站试以本地中熟玉米塔石其力克复播,获得成功(产量比本地英艾孜、云得皮得等早熟品种提高30％)。一九六○年又通过和田地区30个玉米品种的分期播种试验证明,金皇后、维字156、小白马牙、黄金塔
The Hotan Prefecture is located in the southwestern part of southern Xinjiang, the Karakoram Mountains to the south, the Taklamakan Desert to the north, and has less impact on the marine air currents, resulting in less rainfall and dry climate. However, ample sunshine and plenty of heat, the annual frost-free period of 250 days, the average daily temperature greater than 10 ℃ of the accumulated temperature of 4,330 ℃. After June each year, the temperature is stable and there is plenty of water, which will be conducive to compound broadcasting. The local peasants are accustomed to planting corn after receiving wheat and harvesting twice a year. However, due to the improper selection of cultivars and extensive cultivation, the yield of corn replanting is very low, failing to give full play to the yield potential of natural conditions. In 1958, I tried to replicate the locally matured maize tartar in a succession of plots (the yield was 30% higher than that of the native Aizi and Yundepi De precocious varieties). In 1960, it was proved through staging sowing of 30 maize varieties in the Hetian area that the Golden Empress, Victoria Word 156, Little White Horse Tooth, Gold Tower
