锌钼与腐殖酸配施对大蒜生理特性及土壤性质的影响

摘要

Effects of combined application of zinc,molybdenum and humic acid on chlorophyll content, antioxidant,garlic yield and soil physical,chemical and biological indicators were studied in this paper. The experiment consists of 4 treatments,including regular fertilizing(CK),regular fertilizing +zinc+molybdenum(T1), regular fertilizing+humic acid(T2),regular fertilizing+ zinc+molybdenum+humic acid(T3). The results indicated that T3 could not only increase the plant height,stem diameter,garlic diameter and yield,but also significantly increase the chlorophyll content of garlic leaf blades,improve the activities of POD,SOD and CAT. T3 was also beneficial for strengthening soil enzyme activity,improve soil physical and chemical properties. The garlic plant treated by T3 could yield 20.13 t·hm-2,which was 14.83% more than that by traditional fertilizing at locality. To put it short,T3 has very good effect on increasing garlic yield and improving soil fertility in Henan Province.%针对影响大蒜生长的土壤障碍因子，研究锌钼与腐殖酸配施对大蒜叶片叶绿素含量、抗氧化能力、大蒜产量及土壤物理、化学、生物学指标的影响。设常规施肥（CK）、常规施肥+锌肥+钼肥（T1）、常规施肥+腐殖酸（T2）、常规施肥+锌肥+钼肥+腐殖酸（T3）4个处理。结果表明，锌钼与腐殖酸配施能够显著提高大蒜叶片叶绿素含量，提高过氧化物酶（POD）、超氧化物歧化酶（SOD）、过氧化氢酶（CAT）活性，有利于增强土壤酶（脲酶和磷酸酶）活性，改善土壤理化性质，并能显著增加大蒜株高、茎粗、蒜头直径及产量。T3处理的大蒜产量可达20.13 t·hm-2，比当地传统施肥增产14.83%。综上所述，锌钼与腐殖酸配施对于河南蒜区的大蒜产量和土壤质量的改善具有很好的效果。
