随着播期的推迟,小麦产量和品质亦随之降低。因此,晚播小麦的一切高产优质栽培技术都必须在争取早播种的前提下,依据当地当时的生态条件,因地制宜选用适宜品种,适度增加播种量精细播种,加强中后期肥水管理,采用催芽播种,地膜覆盖等争早技术,夺取晚播小麦优质高产。1 选用适宜晚播的优良品种晚播小麦生长发育期间积温少,生育期缩短,生长发育较快,必须选用弱春性或春性品种,春化时间短,生长快,发育早,幼穗分化强度大、进度快,容易
With the delay of sowing date, wheat yield and quality will also be reduced. Therefore, all late-sowing wheat high-yield and high-quality cultivation techniques must strive for early sowing under the premise, according to the local ecological conditions at that time, according to local conditions appropriate selection of appropriate varieties, moderately increase the sowing of fine sowing, strengthen fertilizer and water management in the late, Such as film mulching early competition technology, seize the evening broadcast high-quality wheat yield. 1 selection of late-sowing good varieties late-maturing wheat during the growth and development of small accumulated temperature, shortened growth period, rapid growth and development, we must choose the spring or spring varieties, vernalization time is short, fast growth, early development, panicle differentiation Strong, fast, easy
