摘要
通过对土壤容重、土壤田间持水量、饱和含水量、剖面土壤含水量以及玉米产量的测定分析,研究不同耕作方式对土壤物理性状及玉米经济效益的影响。结果表明:相对于传统耕作不覆盖(CT),在0~5cm土层深度,免耕秸秆覆盖(NTS)可以显著降低土壤容重,传统耕作喷洒保水剂(CTA)和传统耕作塑料地膜覆盖(CTF)对降低土壤容重也有一定效果;NTS处理可以提高0~10cm土层的田间持水量,CTA处理对田间持水量的变化有一定的稳定作用,CTF处理对田间持水量的影响较为不利;不同耕作处理的饱和含水量变化与田间持水量变化相似,NTS处理具有较好的饱和含水能力,而CTF处理饱和含水能力最弱;在10~50cm土层,CTF处理的土壤含水量最高,CTA处理较高,生长期内NTS处理土壤含水量变化较稳定;经济效益为CTF>CT>CTA>NTS。
Based on the measurement and analysis of soil bulk density,field capacity,saturated water content and profile soil water content and maize production.The results showed that,compared to conventional tillage(CT),NTS significantly reduced the soil bulk density in 0~5cm soil depth.To some extent,CTF and CTA treatments could reduce the soil bulk density as well.NTS could increase 0 ~ 10 cm soil field capacity,CTA have a stabilizing effect on the field capacity variations.However,the field capacities under CTF were lower.Similarly,saturated water contents under different tillage treatments had similar changes as the field capacity,NTS had the best saturated and water-holding capacity,whereas the CTF with the worst capacity.The soil water contents at 10 ~ 50 cm soil depth under CTF and CTA were higher than other tillage managements.The soil water contents under NTS were more stable in the whole corn growing season than other tillage managements.The economic benefits followed the order;CTF>CT>CTA>NTS.
