新疆和田河、叶尔羌河流域光热资源丰富,适宜两熟栽培。1991~1992年两河流域建成小麦玉米套种吨粮田36.2万亩。最佳种植方式为70~75cm带种6行小麦,预留50~45cm空行套种2行玉米;最佳配套品种:小麦为冀麦5418和冀麦76,玉米为Sc704和掖单12;最佳施肥量为小麦有机肥3t+N_15P_12,玉未有机肥2t+N_15;投产比为1:2.3;光能利用率提高14.3%,热能利用率提高14.8%,净同化率提高12.8%。
Xinjiang Hotan River, Yarkant River Basin light and heat resources, suitable for two cultivation. From 1991 to 1992, a total of 362,000 hectares of wheat grain were planted in the two rivers. The best planting methods were 6 rows of wheat with 70 ~ 75 cm, and 2 rows of maize with 50 ~ 45 cm blank rows. The best varieties were: Ji Jimi 5418 and Ji Ma 76, corn was Sc704 and Yedan 12; The optimum amount of fertilizers was 3t + N_15P_12 for wheat and 2t + N_15 for jade without organic fertilizer; the ratio of production to use was 1: 2.3; the utilization of light energy increased by 14.3%, the utilization of heat energy increased by 14.8% and the net assimilation rate increased by 12.8 %.
