摘要
在豫北新乡的灌溉试验表明,无论是在干旱年份或降水正常年份,小麦生育中后期进行适当的灌溉能明显地提高小麦的籽粒产量、蛋白质产量、蛋白质含量和赖氨酸含量。在豫北一般干旱年份中后期灌溉量宜控制在100—150立方米;在降水较正常的年份中后期灌溉量宜控制在70—98立方米。小麦生育中后期80厘米土层的平均含水量以15.6％左右为适宜。生育后期过多的灌溉会明显降低小麦籽粒产量、蛋白质含量和赖氨酸含量。
The irrigation trials in the north of Henan showed that the grain yield, protein yield, protein content, lysine content of winter wheat are significantly raised by appropriate irrigation at middle final stage, whether the rainfall is relatively poor or normal.In the drying year, irrigation requirement controlled 100-150 m3 is fit, but in normal year 70-98 m3 is better .At the middle final growing stage of wheat, the soil suitable average moisture content in 80 cm depth is 15.6%. In the final growing period, if irrigation requirement is excessively more, it can significantly reduced the grain yield, protein content, lysine content of winter wheat.
