| 摘 要： | 以草炭、椰糠为对照,研究腐熟木薯茎秆对番茄、黄瓜、丝瓜、茄子、大吊瓜及西瓜的育苗效果,为木薯茎秆作为育苗基质提供依据。育苗结果表明:(1)原木薯茎秆用于番茄育苗时,其发芽率、株高、茎粗及真叶数与草炭育的番茄效果相当;过2 mm筛木薯茎秆对番茄育苗效果不如草炭,但优于椰糠;原木薯茎秆用于黄瓜育苗时,其发芽率、株高、茎粗及真叶数与草炭、椰糠育的黄瓜效果相当;原木薯茎秆对番茄、黄瓜的育苗效果优于过2 mm筛木薯茎秆。(2)原木薯茎秆、过2 mm筛木薯茎秆对丝瓜、大吊瓜和西瓜的育苗效果不如草炭、椰糠,但对茄子的育苗效果优于椰糠。总的看来,腐熟木薯茎秆可用于番茄、黄瓜、茄子育苗,而不宜单独用于丝瓜、大吊瓜和西瓜育苗。

Effects of Cassava Stalk Substrate on Seedlings |
| |
| Abstract: | This paper used peat and coconut chaff as control to study the seedling effects of cassava stalk substrate on tomato, cucumber, luffa, eggplant, wax gourd and watermelon seedling in order to provide basis of cassava stalk substrate on seedling.The seedling results showed that:(1)Cassava stalk substrate on tomato seedling, its germination percentage, plant height, stem diameter and true leaves number were as well as the seedling effects of peat, and the seedling effects of cassava stalk substrate(Φ<2 mm)were not so well as the effects of peat but were better than the seedling effects of coconut chaff. Cassava stalk substrate on cucumber seedling, its germination percentage, plant height, stem diameter and true leaves number were as well as the seedling effects of peat and coconut chaff. The tomato and cucumber seedling effects of cassava stalk substrate(Φ<2 mm)were not so well as the effects of primary cassava stalk substrate.(2)The seedling effects of cassava stalk substrate and cassava stalk substrate sieved by 2 mm sieve on luffa, wax gourd and watermelon were not so well as the effects of peat and coconut chaff, but the effects on eggplant were better than the effects of coconut chaff. On the whole, maturity cassava stalk could be used on tomato, cucumber and eggplant seedling, but not suitable for luffa,wax gourd and watermelon seedling. |
