研究土壤增氧条件下施加绿肥(紫云英)和施加农家肥(干牛粪)对水稻生长和产量的影响。于水稻生长过程中不同时期采集处理组土壤样品,分析其碱解氮含量、速效磷含量和速效钾含量的变化;于水稻成熟后测定各处理组水稻的分蘖数、叶面积指数和产量等农艺性状指标。结果表明:增氧处理能够促进有机肥肥效元素的释放,提高土壤有效态肥效元素含量;增氧条件下,施加绿肥和农家肥均可促进水稻的分蘖生长,OAF(增氧施绿肥)和OCF(增氧施农家肥)处理的总分蘖数分别为51.34和50.16,对照组总分蘖数为36.93;增氧施农家肥处理比单施农家肥处理组的叶面积指数显著提高,增氧施绿肥处理与不增氧施绿肥处理组叶面积指数的...

The effects of oxygen aeration and applying astragalus sinicus and dry cow dung on rice growth and yields were researched by analyzing changes of contents of AN (alkaline hydrolysis nitrogen), AP (available phosphorous) and AK (available potassium) in soil samples collected at different treatments and different stages of rice growth. The agronomic traits of tiller numbers, leaf area index and yields were recorded after rice maturation as well. The results showed that oxygen aeration could enhance elements release from organic fertilizers and increase available fertilizer contents. Tiller growt...
