摘要: 为研究叶面喷施腐植酸水溶肥对枇杷[Eriobotrya japonica (Thunb.) Lindl.]幼苗生长的影响,以大五星枇杷幼苗为材料,叶面喷施不同稀释浓度(700、1 000、1 300、1 600倍)的腐植酸水溶肥,以喷施等量清水为对照(CK),测定腐植酸水溶肥对枇杷幼苗生物量、光合色素含量和抗氧化酶活性的影响。结果表明,叶面喷施不同浓度的腐植酸水溶肥提高了枇杷幼苗茎杆和叶片生物量、光合色素含量,且均以稀释1 000倍效果最好。稀释1 000、1 300倍腐植酸水溶肥处理提高了枇杷幼苗过氧化氢酶(CAT)、过氧化物酶(POD)和超氧化物歧化酶(SOD)活性。枇杷幼苗茎杆、叶片生物量与叶绿素a、叶绿素b、类胡萝卜素含量、CAT活性、POD活性和SOD活性呈正相关。因此,叶面喷施腐植酸水溶肥能够促进枇杷幼苗生长,且以稀释1 000倍最佳。

Abstract: In order to study the effect of foliar spraying humic acid water soluble fertilizer on the growth of loquat[Eriobotrya japonica (Thunb.) Lindl.] seedlings, the effects of humic acid water soluble fertilizer with different dilution ratios (700, 1 000, 1 300 and 1 600 times) on the biomass, taking spraying equal amount of water as contrast(CK), photosynthetic pigment content and antioxidant enzyme activity of Dawuxing loquat seedlings were determined. The results showed that foliar application of different concentrations of humic acid water soluble fertilizer increased the biomass and photosynthetic pigment content of the stem and leaf of loquat seedlings, and the effect was the best at 1 000 times. The activities of peroxidase(POD) and catalase(CAT) and superoxide dismutase (SOD) of loquat seedlings were increased by 1 000 and 1 300 times of humic acid water soluble fertilizer. The stem and leaf biomass of loquat seedlings were positively correlated with chlorophyll a, chlorophyll b, carotenoid content, POD activity, SOD activity and CAT activity. Therefore, foliar spraying humic acid water soluble fertilizer could promote the growth of loquat seedlings, and the best was 1 000 times.

Key words: humic acid water soluble fertilizer, loquat[Eriobotrya japonica (Thunb.) Lindl.] seedlings, growth, photosynthetic physiology, antioxidant physiology
