伊犂地区地形复杂、高差悬殊,大河灌区,山水地、山寒地的水、土、肥条件不同,经营条件各有特点。而目前冬小麦品种单纯,一般都用乌克兰0246,既不利于高产稳收,也不利于播种面积的继续扩大。因此,搭配栽培不同品种,对于发展农业生产具有重要的意义。 一、播期早晚的品种搭配 伊犂地区冬麦播种面积占粮食作物总播面积40％,特别是西部大河灌区占的比重更大。在短短的适播期10—15天中,完成播种任务,劳畜力的紧张程度是可以想见的。伹不同品种对播期的要求并不一致,有些品种宜于早播,有
Ili terrain complex, high disparities, irrigation areas, landscapes, mountains and cold water, soil, fertilizer different conditions, the operating conditions have their own characteristics. At present, winter wheat varieties are pure and generally use Ukraine 0246, which is not conducive to high and stable yield, nor is it conducive to the continued expansion of sown area. Therefore, with different varieties of cultivation, for the development of agricultural production is of great significance. First, the varieties of sowing sooner or later with Ili area Winter wheat sown area accounted for 40% of the total sowing area of food crops, especially in western Dahe Irrigation accounted for a larger proportion. In the short period of 10-15 days suitable for sowing, it is conceivable that the task of sowing seedlings should be strained.伹 different varieties of sowing requirements are not consistent, some varieties suitable for early sowing, there
