摘要:

以番茄为试验对象,采用田间小区试验,通过测定不同生育期番茄叶片的相对叶绿素含量、株高、茎粗、单株花数、单株果数、可溶性固形物含量、果径、单果质量,比较了两种含腐殖酸液体肥料对番茄农艺性状和产量的影响。结果表明:施用黑力旺含腐殖酸液体肥料的番茄株高、理论产量显著优于施用鱼蛋白含腐殖酸液体肥料的;施用黑力旺含腐殖酸液体肥料可显著提高番茄在开花坐果期和结果期的单株果数;施用两种含腐殖酸液体肥料对相对叶绿素含量、可溶性固形物含量、果径、单果质量无显著性差异;施用黑力旺含腐殖酸液体肥料的经济效益较优。

Abstract:

Taking tomato as the experimental object, a field plot experiment is carried out to compare the effects of two liquid fertilizers containing humic acid on tomato agronomic characters and yield by measuring the relative chlorophyll content of tomato leaves, plant height, stem diameter, flower number per plant, fruit number per plant, soluble solid content, fruit diameter and single fruit weight at different growth stages. The results show that the plant height and theoretical yield of tomato treated with Heiliwang liquid fertilizer containing humic acid are significantly better than those treated with fish protein liquid fertilizer containing humic acid. Applying Heiliwang liquid fertilizer containing humic acid can significantly increase the number of fruits per plant in flowering and fruit setting stage and fruiting stage of tomato. There is no significant difference in relative chlorophyll content, soluble solid content, fruit diameter and single fruit weight between the two liquid fertilizers containing humic acid. The economic benefit of applying Heiliwang liquid fertilizer containing humic acid is better.
