不同耕作方式对土壤耕作层水、肥保持能力及玉米产量的影响分析

Effect of Different Cultivation Methods on Maintenance Capacity of Water and Fertilizer,Surface Soil and Yield of Corn

水分和养分是促进作物生长的主要因素。以东单60为材料进行秸秆覆盖试验,探讨了不同耕作方式对土壤耕作层水、肥保持能力及玉米产量的影响。采用SPSS、Excel统计软件对实测数据进行分析,结果表明:耕层土壤含水率的变化趋势为:免耕覆盖>浅松覆盖>条带覆盖>传统耕作;土壤养分的变化趋势为浅松覆盖>免耕覆盖>条带覆盖>传统耕作。综合考虑免耕覆盖保水效果最好、浅松覆盖保肥效果好且增产效果最好。

Moisture and fertilizer are important factors which can accelerate the growth of crops. This paper explores different cultiration methods that affect maintenance capacity of water, fertilizer and yield by making experiments on corn straw mulching. The experiment data was analyzed by SPSS and Excel. The results show that the trend of content of water in soil is zero-tillage covering〉 surface-pulverize covering 〉cincture-covering〉traditional cultivation and the trend of content of fertilizer in soil is surface-pulverize covering〉 zero-tillage covering〉 cineture-covering〉traditional cultivation. In conclusion, zero-tillage covering is the best in maintenance capacity of water, surface-pulverize covering is the best in maintenance capacity of fertilizer and yield.
