摘要
以辣椒为试材,研究不同覆盖方式对土壤环境及辣椒生长的影响。结果表明,与对照相比,地膜和稻壳覆盖处理的土壤保持较高的温度和含水量,从而良好的土壤环境提高了辣椒硝酸还原酶活性和根系活力,促进了根系的生长;同时稻壳和地膜覆盖还促进了辣椒幼苗地上部的生长,表现在株高、茎粗的快速生长,叶绿素含量增高;提高辣椒的早期产量,稻壳处理的辣椒早期产量为对照处理的3.00倍,与地膜处理的差异不显著。总之,稻壳覆盖可以达到地膜覆盖的效果。
The effects of different mulching methods on soil environment and pepper growth were investigated in this experiment.The results were as follows:Compared with the control,soil temperature was increased and soil water content had been kept up higher under plastic mulch and rice husk mulch.Nitrate reductase activity and root activity of pepper were improved under good soil environment,which promoted pepper seedlings to growth;it showed that the growth of plant height and stem diameter was fast,chlorophyll con...
