不同牛粪配比基质对盆栽五彩观赏椒生长的影响

Effects of Different Proportions of Cow Manure on Growth of Potted Colorful Ornamental Pepper

为筛选出适于盆栽的五彩观赏椒基质配比,以椰糠、园土、牛粪组成6种不同配比基质,分析五彩观赏椒长势的动态变化、植株及结果性状、根冠比差异。试验结果表明,不同牛粪配比基质对五彩观赏椒长势有影响,在定植20d内,各处理的株高、株幅、叶片数差异小,30~50d处理差异拉大,至50d时,T5[(椰糠∶园土)∶牛粪=10∶4]的株幅、叶片数均最大。T5的植株性状、结果性状和根冠比均最优,T6其次。因此,T5基质的牛粪配比最适合五彩观赏椒盆栽。

In order to select out the suitable substrate proportion for potted colorful ornamental pepper, six different matching substrates composed of coconut chaff, orchard soil and cow manure were used to analyze the dynamic changes of growth potential, growth and fruit characters, and the root-shoot ratio of colorful ornamental pepper. The results showed that different proportions of cow manure affected the growth potential of colorful ornamental pepper. During 20 days of planted, the difference in plant height, plant width and leaf number was small, while during 30 to 50 days after planted, the difference of different treatments was widened. Being planted 50 days, the width and leaf number of the T5 [(coconut chaff:orchard soil)∶cow manure=10∶4] treatment were largest. The growth, fruit characters and root-shoot ratio of the T5 treatment were the best, and followed by T6 treatment. So, when the ratio of (coconut chaff∶orchard soil)∶cow manure was 10∶4, it was most suitable for potted colorful ornamental pepper.
