| 摘 要： | 针对北方烟田多年连作而产生土壤肥力衰退和产量下降等问题,通过大区对比试验方法,以JY-02为供试品种,腐殖酸为土壤改良剂,于2010年在黑龙江省汤原烟区连作5a土壤上进行试验,研究其对土壤性状及烟株生长的影响。结果表明:腐殖酸用作基肥降低连作烟田土壤容重,提高土壤含水量,增加土壤养分,明显促进烟株生长,增产8.30%～16.26%,其中施用腐殖酸300kg.hm-2效果最好。

| Abstract: | Aiming at the terrible situation of continuous cropping tobacco field such as fertility decay and yield drawdown,with the method of large-plot contrast test,JY-02 as test material and humic acid as soil amendment,the effect on soil characteristics and plant growth of five years continuous cropping tobacco field at Tangyuan,Heilongjiang province was conducted in 2010.The result showed that using humic acid as base fertilizer could reduce soil volume weight,improve its moisture and nutrition,promote the growth of the plant obviously,the yield increased 8.30%~16.26%.The effect of the dosage of 300 kg·hm-2 was better. |
