依据小麦品种变化再谈良种良法配套

Discussion on Fine Varieties Combining Suitable Cultivation Methods Based on Wheat Variety Evolution

根据1981-2013年河南省(国家黄淮南片)审定的小麦新品种的产量及成产三因素变化情况,简要论述了小麦新品种培育与小麦栽培技术的关系,指出河南省小麦新品种已具有较高生产能力,但大田生产因生产条件限制和栽培技术不配套而未能发挥新品种的生产潜力。提出了河南省小麦生产应当进一步重视栽培配套技术,打破春节过后即追肥浇水的传统习惯,认真抓好整地质量,强化生育中期肥水管理两项关键技术的推广落实。

Based on the changes of grain yield and its three components in the cultivars authorized in Henan province （Southern Huang-huai area）for 30 years,the relationship between wheat breeding and cultivation techniques was discussed briefly.The result showed that the new varieties from Henan province already had a high production capacity,but their potential productivity did not bing into play fully due to the restrictions of production conditions and cultivation techniques.It was suggested that more attention should be put on the conformable cultivation technology of wheat：breaking some bad traditional customs like fertilizing and watering immediately after Spring Festival,makeing great efforts to the quality of soil preparation,and strengthening fertilizing and watering managements in mid-growing period of wheat.
