摘要

研究了不同土壤改良剂(聚丙烯酸钾

聚丙烯酰胺

腐殖酸钾

聚丙烯酸钾+腐殖酸钾

聚丙烯酰胺+腐殖酸钾)对土壤紧实度及燕麦生长状况的影响。结果表明

各改良剂处理均能减小土壤紧实度

表现为:聚丙烯酸钾+腐殖酸钾>聚丙烯酰胺+腐殖酸钾>聚丙烯酸钾>聚丙烯酰胺>腐殖酸钾>对照

土壤紧实度均随着土壤深度增加而增加;土壤改良剂对燕麦株高和干物质量具有显著的提高作用

复配处理株高优于其他单施处理;土壤改良剂处理下籽粒产量均显著高于对照

其中聚丙烯酸钾+腐殖酸钾和聚丙烯酰胺+腐殖酸钾籽粒产量较其他处理高

分别为4 694.2和4 566.9kg/hm

较对照增产21.66%和18.36%

生物产量的增产效果表现同籽粒产量;各土壤改良剂处理水分利用效率均显著高于对照

其变化趋势与产量变化趋势一致

复配处理效果更佳。

Abstract

Effects of different soil amendments on soil compaction and growth status of oat were studied.Results showed that all the soil amendments could reduce soil compaction;the order of them was potassium polyacrylate+potassium humate>polyacrylamide+potassium humate+potassium humate>potassium polyacrylate>polyacrylamide>potassium humate> CK;and soil compaction increased with the increase of soil depth.Soil amendments significantly increased plant height of oat and dry matter weight

and the height for the mixed use was higher than the single use.Grain yields under the amendment treatments were significantly higher than that under the control.The yields for potassium polyacrylate+potassium humate and polyacrylamide+potassium humate were higher than that for the single use

being 4 694.2and 4 566.9kg/hm2 with the increments of 21.66% and 18.36%

respectively.Biological yield had the same effect as grain yield.The WUE under the amendment treatments was significantly higher than that under the control

and the WUE under mixed amendment was higher than that under other soil amendments.
