土壤调理剂对土壤肥力和木薯产量的影响
|
摘要
土壤调理剂是由农用保水剂及富含有机质、腐殖酸的天然泥炭或其他有机物为主要原料,辅以生物活性成分及营养元素组成,经科学工艺加工而成的产品。试验以木薯品种新选048为材料,土壤调理剂用量为0、450、900、1 350 kg/hm~2,分别在木薯苗期、块根形成期、块根膨大期、工艺成熟期进行数据采集,主要测定木薯发芽率、株高、茎粗、叶面积指数、块根数、块根长等木薯农艺性状,并测定土壤碱解氮、速效磷、速效钾、有机质含量等物化指标。结果显示土壤调理剂能提高土壤孔隙度和保水能力,增加土壤有机质、氮、磷、钾含量,从而促进木薯发芽、生长以及对土壤养分的吸收,提高木薯产量。
Soil conditioner consists of agricultural super absorbent polymers,and is rich in organic matter,natural peat humic acid as the main raw material,or other organic matter with biological active ingredient and nutrition elements,processed by science and technology products. This study discussed the effect of soil conditioner on the growth and development of cassava,and provided a theoretical basis for the application of soil conditioner in cassava production. The experiment was conducted from April 2016 to January 2017,with the variety of cassava Xinxuan048 as the materials,respectively 0 kg/hm~2,450 kg/hm~2,900 kg/hm~2,1 350 kg/hm~2 as the four treatments,Data collection was conducted in the seedling stage of cassava,root formation stage,root expansion stage and process maturity phase.Main determination of cassava germination rate,plant height,stem diameter,leaf number,root number,root length and other agronomic traits,and the determination of soil water content,bulk density,porosity,such as nitrogen,phosphorus and potassium content,organic matter content index. Results showed that soil conditioner can increase soil porosity and water retention,increase soil organic matter,nitrogen,phosphorus and potassium content,thereby promoting cassava germination,growth and soil nutrient absorption,increase production of cassava.
