黔西喀斯特区秸秆覆盖对坡耕地产流产沙特征的响应

open access: yesShuitu Baochi Xuebao, 2021
基于2018-2019年野外径流小区定位观测资料,以玉米单作无秸秆覆盖处理(M0)为对照,探索了玉米单作处理和不同秸秆覆盖量(M1~M5,1 111,2 222,3 889,5 556,6 944 kg/hm2)对贵州省黔西喀斯特区坡耕地产流产沙特征的影响。结果表明:(1)不同降雨等级下,秸秆覆盖具有较好的水土保持效果,并随覆盖量的增加,产流、产沙总量逐渐减少,但M4与M5处理之间无显著差异(p>0.05);(2)玉米苗期—拔节期各处理产流和产沙量大于后2个阶段,并且各阶段各覆盖处理产流产沙均低于对照;(

覆盖方式对旱地马铃薯阶段耗水量特征和产量的影响

open access: yesShuitu Baochi Xuebao, 2022
为明确不同覆盖方式对旱地马铃薯田土壤耗水、耗水规律、水分利用效率、产量及产量形成的影响,在陇中半干旱农区设置了玉米秸秆带状双行覆盖(SSM2)、玉米秸秆带状单行覆盖(SSM1)、玉米秸秆全覆盖(SFM)、地膜春覆盖(PMS)和地膜秋覆盖(PMA)5种覆盖方式,以传统露地平作为对照(CK)。结果表明:2年试验中,玉米秸秆带状覆盖和地膜覆盖处理土壤贮水消耗量较CK分别增加13.5,14.8 mm。玉米秸秆带状覆盖能显著提高降水对马铃薯耗水贡献率,不同降雨年型内均以SSM2处理贡献率最高,2年分别为95.6 ...

不同降水年型下耕作结合秸秆覆盖对马铃薯耗水特征及产量的影响

open access: yesShuitu Baochi Xuebao, 2023
为探索不同降水年型下耕作结合秸秆覆盖措施对旱作马铃薯生育期土壤贮水量、作物耗水特征和产量形成的影响,连续3年在旱作区秋作物收获后通过设置不同耕作方式(免耕、深松、翻耕)结合秸秆覆盖进行大田试验研究。结果表明,经过3年耕作覆盖处理后,免耕、深松结合秸秆覆盖能显著降低0—40 cm层土壤容重,提高土壤有机质含量。保护性耕作结合秸秆覆盖措施可显著提高马铃薯生育期0—200 cm层土壤贮水量,相对欠水年和欠水年马铃薯全生育期土壤贮水量均以深松覆秸秆处理最高,分别较翻耕不覆盖显著提高15.80%和20.80 ...

小麦秸秆长度、覆盖量对坡面产流产沙的影响

open access: yesShuitu Baochi Xuebao, 2020
为定量研究小麦秸秆覆盖对坡面产沙产流过程及减水减沙效益的影响,采用室内人工模拟降雨试验,研究在降雨强度为90 mm/h时,不同秸秆长度和秸秆覆盖量下的坡面产流产沙特征和产流产沙过程规律,结果表明:(1)在相同秸秆长度下,随秸秆覆盖量增加,产流量产沙量极显著减少 ...
