不同基质对火龙果种子出苗及幼苗生长的影响

摘要

The effects of three kinds of substrates on the seed seedling emergence and growth of two kinds of Hylocereus undatus (red-flesh species and white-flesh species). The results showed that the seedlings of two kinds of Hylocereus undatus emerged fastest on pig manure substrate, and slowest on humus substrate. There was no obvious difference in seedling emergence rate among three kinds of substrates. The seedlings of two kinds of Hylocereus undatus grew best on pig manure substrate, generally on humus substrate,and worst on plant ash substrate.%以红皮白肉、红皮红肉两种类型火龙果种子为材料,在3种不同基质上进行了育苗试验.结果表明:两种类型的火龙果在猪粪基质上出苗最快,在腐殖土基质上出苗最慢;在3种基质上的出苗率无显著差异;幼苗生长状况表现为:在猪粪基质上最优,其次为腐殖土,最差为草木灰.
