摘要
通过试验研究了龙峰生物有机肥对棉花灌根施用浓度和效果,结果表明:用该肥灌根能有效补充棉花生长所需的营养元素,促进棉株生长发育,改善棉株农艺性状,提高棉花产量、改善棉花品质等作用效果;具有使用方法简便,经济、环保、见效快、效果佳等特点;施用此肥后棉花单位面积比对照增加产量89.10～319.95 kg/hm2,增产幅度6.62%～23.77%,霜前花率提高16.20%～29.37%,衣分增加1.61%～2.15%.
The experiment was adopted field test method to probe concentration and effect on cotton root-irrigated of Longfeng bio-organic fertilizer.Results were indicated that it could be replenished nutrition elements on necessary of cotton growing effectively.What＇s more,the fertilizer was also played an essential part on plant-growth increasing,agoronomic character improving and qualitative effectiveness enhancing.So it was included features of simple methods in use,economic and environmental protection,even quick return on earnings.The increasing yield in unit area was achieved 89.10~319.95 kg/hm2,while rate of increasing was 6.62%~23.77%,proportion of pre-frost increasing got 16.20%~29.37%,and the cotton ginning outturn increasing was 1.61%~2.15%.
