摘要
为了筛选新型高效的腐植酸叶面肥,以菠菜和小油菜为试验材料,对9种腐植酸叶面肥的应用效果进行研究。结果表明,腐植酸叶面肥能有效促进菠菜和小油菜的叶面积、地上部分的质量和总质量。A1、A9、A5、A3和A4等5种腐植酸叶面肥对菠菜生长促进作用明显,其中A1的400倍稀释液对促进菠菜的叶面积和地上部分质量效果最显著,分别比对照增加16.33%和34.51%。A9、A3、A8、A5等4种腐植酸叶面肥对小油菜的生长促进作用明显,其中A9的800倍稀释液对小油菜的叶面积、地上部质量和总质量的影响达显著水平,分别比对照增加63.4%、51.3%和52.0%。试验结果还表明腐植酸叶面肥对菠菜和小油菜根重的增加效果不明显。分别对菠菜和小油菜的单株总质量、地上部质量、叶面积和根重等性状进行了相关分析,发现这两种叶菜的单株总质量与叶面积和地上部质量显著相关,叶面积与地上部质量显著相关。试验数据说明腐植酸叶面肥主要促进叶子的生长,通过增加叶面积增加菠菜和小油菜的单株质量和地上部质量。
Effects of 9 humic acid foliar fertilizers on the growth of Spinacia oleracea L.and Brassica campestris L.were studied.The results showed that humic acid foliar fertilizers could effectively promote the leaf area,above-ground mass and total mass of Spinacia oleracea L.and Brassica campestris L.5 humic acid foliar fertilizers A1,A9,A5,A3 and A4,had significant effects on the growth of Spinacia oleracea L.compared with control.Especially,the 400 folds of dilution of A1 could more remarkably increased the leaf area and above-ground mass of Spinacia oleracea L.with a percent of 16.33% and 34.51% respectively.4 humic acid foliar fertilizers,A9,A3,A8 and A5,could significantly improve the growth of Brassica campestris L.The 800 folds of dilution of A9 could improve the leaf area,above-ground mass and total mass of Brassica campestris L.significantly with a percent of 63.4%,51.3 and 52.0% respectively.The results also showed that these humic acid foliar fertilizers had no significant effects on the root of Spinacia oleracea L.and Brassica campestris L..The relation among the leaf area,above-ground mass and total mass was statistically analyzed.Total mass was significantly related with leaf area and above-ground mass.Furthermore,there was asignificant relation between leaf area and above-ground mass.
