摘要
为明确有机肥对甜瓜幼苗生理特性和幼苗质量的作用效果,保证甜瓜高产和优质栽培,采用盆栽方法,设置6个不同有机肥施用量(羊粪与蔬菜专用营养土的质量比分别为0、400、700、1000、1300、1600 g/kg),系统分析了有机肥对甜瓜幼苗生理特性和质量的影响。结果显示:与CK(有机肥用量0 g/kg)相比,不同用量有机肥均具有促进甜瓜生理特性和改善幼苗质量的作用,其中以F4处理(有机肥用量1300 g/kg)效果最为理想,在甜瓜出苗后25 d,幼苗根系活力、叶片叶绿素含量、可溶性蛋白含量、可溶性糖含量、幼苗株高、茎粗、叶面积、根冠比和壮苗指数比CK分别显著提高了95.83%、15.97%、85.01%、61.71%、41.65%、11.76%、33.90%、85.71%和200.00%;虽然F5处理(有机肥用量1600 g/kg)的根系活力、叶片叶绿素含量、可溶性蛋白含量、可溶性糖含量、株高和茎粗均最大,但与F4处理之间差异均不显著,且根冠比、壮苗指数较F4处理有所降低。因此,认为羊粪有机肥用量1300 g/kg更有利于培育甜瓜幼苗。
In order to clarify the effect of organic fertilizer on physiological characteristics and quality of melon seedlings,and to ensure high-yield and high-quality cultivation of melon,six different application rates of organic fertilizer(The weight ratio of sheep manure and special nutrient soil for vegetables were 0,400,700,1000,1300,1600 g/kg,respectively)were set with potted method,and the effects of organic fertilizer on physiological characteristics and quality of melon seedlings were systematically analyzed.The results showed that compared with CK(the application rate of organic fertilizer was 0 g/kg),different application rates of organic fertilizer all had the effects of promoting the physiological characteristics and improving the quality of melon seedlings,among which,F4 treatment(the application rate of organic fertilizer was 1300 g/kg)had the most ideal effect.The root activity,leaf chlorophyll content,soluble protein content,soluble sugar content,plant height,stem diameter,leaf area,root-shoot ratio and strong seedling index of melon seedlings were significantly increased by 95.83%,15.97%,85.01%,61.71%,41.65%,11.76%,33.90%,85.71%and 200.00%,respectively,after 25 d seedling emergence.Although the root activity,leaf chlorophyll content,soluble protein content,soluble sugar content,plant height and stem diameter were all the largest in F5 treatment(the application rate of organic fertilizer was 1600 g/kg),but there was no significant difference between them and those of F4 treatment,and the root-shoot ratio and strong seedling index were lower than those of F4 treatment.Therefore,the research results suggested that the 1300 g/kg of sheep manure organic fertilizer application rate was more beneficial to cultivate melon seedlings.
