采用中麦175品种为试验材料,研究不同整地方式对小麦生长发育和产量的影响,从全年产量、经济效益、播种质量以及土壤容重等多种指标对不同整地方式进行评价,找出北京市最适宜的种植小麦整地方式,并向生产推荐。通过试验得出如下结论:重耙+耕翻+旋耕(玉米秸秆粉碎2次)667 m2产最高达405.4 kg,比对照增产11.0 kg,旋地2次产量最低372.7 kg,比对照减产21.7 kg。处理2(耕翻+重耙+旋耕)667 m2效益最高达239.6元,处理4(深松+旋耕)667 m2效益最低195.8元,比对照低26.3元,深松机耕费70元/667 m2,增加了667 m2成本,造成效益降低。有耕翻和深松的处理分蘖成穗率较高。各整地方式对生育期、群体动态和单株性状没有明显影响。深松能增加播种深度,只旋地2次没有耕翻作业的播种深度最浅。
Zhongmai 175 was used as test material to study the effects of different land preparation methods on the growth and yield of wheat. Based on the annual yield, economic benefits, sowing quality and soil bulk density, The most appropriate way to plant wheat, and recommended to the production. The results of the experiment are as follows: heavy rake + tillage + rotary tillage (corn stalks crushed twice) up to 405.4 kg of 667 m2, 11.0 kg more than the control, the lowest of 2 rotations of 372.7 kg, 21.7 kg less than the control . 667 m2 for treatment 2 (tillage + heavy harrow + rotary tillage) has the highest benefit of 239.6 yuan and the lowest benefit of 667 m2 for subsoiling 4 (subsoiling + rotary tillage) of 195.8 yuan, 26.3 yuan lower than the control and 70 yuan / 667 for subsoiling machine m2, an increase of 667 m2 cost, resulting in reduced efficiency. There are plowing and subsoiling tiller processing spike rate higher. The land preparation methods had no significant effect on the growth period, population dynamics and plant traits. Deep pine can increase the sowing depth, the only sown two times without tilling the most shallow planting depth.
