聚丙烯酸钠对3种土壤持水能力及作物产量的影响

Shuitu Baochi Xuebao, 2008
在离心机模拟不同水吸力条件下,研究了聚丙烯酸钠(sodium polyacrylate记作SP)5种使用浓度(占干土质量0,0.01%,0.08%,0.2%与1%)对3种土壤(砂土、壤土、黏土)持水能力的影响;采用大田试验研究了地表撒施2 g/m2SP对冬小麦与下季玉米产量及WUE影响。结果表明:3种土壤在0.01 MPa至1.5 MPa水吸力下的持水能力随着SP用量的增加而增加,砂土的作用效果较壤土、黏土更显著;3种土壤适宜浓度为0.08%~0.2%,最佳用量为0.2%,此用量条件下砂土、壤土 ...

椰糠型生态保育基质的水力-入渗特性及配比寻优

Shuitu Baochi Xuebao
[目的] 荒漠戈壁因降水量少、蒸发量大等环境因素胁迫,植被稀疏,水土流失严重。探索适宜的土壤改良方法,以提升其保水性、持水性,对于荒漠化防治及戈壁生态农业发展十分重要。[方法] 以无椰糠基质组别T0(风沙土∶有机肥∶人造泥炭=7∶3∶1)为对照,对理化性质较好的3组配比椰糠型生态保育基质(风沙土∶椰糠∶有机肥∶人造泥炭=3.5∶3.5∶3∶1或3∶4∶3∶1或2∶5∶3∶1,依次为T1、T2、T3)进行水力-入渗特性试验;利用离心机法测定基质水分与吸力的关系,探究该基质的水力特性 ...
