Effects of Water and Straw Treatment on Seedling Quality and Yield of Maize
In order to mitigate the adverse effects of drought on the development of summer maize seedlings caused by climate change,using'Zhengdan 958'as experimental material,the effects of different treatment combinations on soil moisture and growth of maize seedling were studied.The results showed that the soil moisture content increased with the depth of the soil layer,and the pattern was moist soil,wheat straw returning to the field＞normal moisture content,wheat straw returning to the field＞moist soil,wheat straw not returning to the field＞dry soil,wheat straw returning to the field＞normal moisture content,wheat straw not returning to the field＞dry soil,wheat straw not returning to the field.SPAD value,photosynthetic rate and yield showed the same trend,normal moisture content,wheat straw returning to the field＞moist soil,wheat straw returning to the field＞moist soil,wheat straw not returning to the field＞normal moisture content,wheat straw not returning to the field＞dry soil,wheat straw returning to the field＞dry soil,wheat straw not returning to the field.Therefore,compared with the removal of stubble,plain stubble can better improve the soil water environment,increase the emergence rate and photosynthetic rate of maize,and increase the yield,which can be widely applied in production.
