【摘要】 [目的]研究扬麦14号新品种在江苏省里下河地区腹地种植时长势对产量和品质的影响。[方法]采用随机区组排列,设定了5个基本苗处理,分别为120万1、80万2、40万3、00万3、60万/hm2,研究小麦长势对产量和品质的影响。[结果]小麦长势对产量和品质都有明显影响,不同生育阶段的不同长势指标对其影响的程度不尽相同。[结论]各个生育阶段的田间管理工作都不能放松,要加强长势调控力度,使其向着高产优质的方向发展。更多还原

【Abstract】 [Objective] The purpose was to study the influence of the growth of a new variety Yangmai 14 planted in the hinterland of Lixiahe district in Jiangsu Province on the yield and quality.[Method] In the field test with randomized block arrangement,5 kinds of base seedling treatments were set up,being 1.2×106, 1.8×106,2.4×106,3.0×106 and 3.6×106 plants/hm2 resp.The influence of wheat growth on the yield and quality were studied.[Result] The wheat growth situation had obvious influence on both yield and quality and the influence degrees of different growth indices in different growing stages were different.[Conclusion] The field management in each growing stage couldn’t be loosened and the growth regulation should be strengthened to make it develop in the direction of high yield and quality.更多还原
