几种肥料对青菜苔生理指标及抗黑根病的影响

THE EFFECT OF 1125 ON GREEN VEGETABLE RHIZOCTONIA SOLANI

为筛选出高效低毒 ,符合生产绿色食品要求的制剂 ,选用 112 5肥药双效剂、植物生理平衡剂、光合微肥和黄腐酸盐对青菜苔生理指标及抗黑根病进行了试验研究。结果表明 :112 5肥药双效剂的 3 0 0倍液在降低青菜苔黑根病发病率 ,增大根冠比方面差异极显著优于黄腐酸盐 ;在增加青菜苔POD活性方面 ,差异极显著优于黄腐酸盐、光合微肥 ,显著优于植物生理平衡剂 ;在降低青菜苔相对电导率方面 ,喷施光合微肥和 112 5肥药双效剂 ,差异极显著优于黄腐酸盐 ,显著优于植物生理平衡剂 ;在贮存期降低黄叶率方面 ,喷施 112 5极显著优于喷施光合微肥 ,而与喷施植物生理平衡剂差异不显著 ;在增加青菜苔叶绿素含量方面 ,喷施 112 5的 3 0 0倍液优于植物生理平衡剂 10 0倍液、黄腐酸盐 10 0 0倍液、光合微肥 5 0 0倍液 ,但差异不显著。综合各项表明 ,112

An experiment was carried out to study the effect of 1125 with plant physiology balance dose or light synthetic fertilizer and Fulvic acid salt on green vegetables Rhizoctonia solani The result showed that 300× solution of 1125 was much more remarkable than Fulvic acid salt and ck in reducing incidence of green vegetables Rhizoctonia solani and in increasing rate of root and crown, much more remarkable than Fulvic acid salt with light synthetic fertilizer or ck, more remarkable than plant physiology balance dose in increasing activity of POD In reducing relative electricity of green vegetables it is much more remarkable than Fulvic acid salt or ck and plant physiology balance dose In all, 1125 is more effective than other fertilizers in regulating plysiological supersession and resising Rhizoctonia solani
