摘要
[目的]在相同播量和播期下筛选新麦26的适宜播种方式。[方法]2018-2019年,在新郑市城关乡敬楼村开展强筋小麦新麦26不同播种方式大田对比试验。播种方式设3个处理和1个对照:免耕沟播、立体匀播、宽窄行播种和等行距条播(CK),3次重复。分别调查出苗率、成穗率、有效穗数、穗粒数和千粒重,收获时测产,计算产量。[结果]免耕沟播产量为8141.55 kg/hm^2,立体匀播产量为7883.85 kg/hm^2,宽窄行播种产量为8199.15 kg/hm^2;均高于对照的产量。[结论]宽窄行播种、免耕沟播、立体匀播3种播种方式出苗均匀度好于对照,能够减少缺苗断垄数量,改善小麦群体结构,有利于新麦26产量水平的提高;免耕沟播、立体匀播集整地、施肥、播种、镇压等多道工序为一体,能实现节本增效,对于晚播抢墒播种优势明显。
[Objective]To screen appropriate sowing method of strong gluten wheat Xinmai 26 under the same sowing amount and sowing time.[Method]The field contrast test of different sowing methods of strong gluten wheat Xinmai 26 was conducted at Jinglou,Xinzheng district from 2018 to 2019.Three treatments and one control were compared with three repeats:no-tillage ditch sowing,three-dimensional uniform sowing,wide narrow row sowing,row sowing(CK).Stem tiller number,effective spikelet number,grain number per spikelet,1000-grain weight were investigated respectively to measure the production when harvest.[Result]The production of no-tillage ditch sowing was 8141.55 kg per hectare.The production of three-dimensional uniform sowing was 7883.85 kg per hectare.The production of wide narrow row sowing was 8199.15 kg per hectare.The production of three treatments were more than control.[Conclusion]The uniformity of seedling emergence of wide narrow row sowing,no tillage ditch sowing and three-dimensional uniform sowing is better than that of the control,which can reduce the number of seedlings lacking and ridge cutting,improve the structure of wheat population,and improve the yield level of Xinmai 26.No tillage ditch sowing and three-dimensional uniform sowing integrate multiple processes such as land preparation,fertilization,sowing and suppression,which can achieve cost saving and efficiency increasing.It is very useful for late sowing and soil moisture saving sowing.
