八種植物在NO3-/NH4+為50/50濕地下的生長(zhǎng)與競(jìng)爭(zhēng)

摘    要
本文在NO3-/NH4+為50/50的情況下，研究蘆竹、蘆葦、美人蕉、菩提子、千屈菜、杭子梢、合萌、白茅等8種濕地植物的生長(zhǎng)與競(jìng)爭(zhēng)。1）8種植物在相同條件下獨(dú)立培養(yǎng)時(shí)表明：蘆竹、白茅、美人蕉的生物量大于蘆葦、菩提子、杭子梢、合萌的生物量（P<0.05）。蘆竹、白茅、美人蕉三種植物間無(wú)差異，千屈菜、蘆葦、菩提子、杭子梢、合萌五種植物間無(wú)差異。株高和冠幅的大小與生物量基本保持一致。2）8種植物混合種植時(shí)表明：菩提子、蘆竹、美人蕉、千屈菜的生物量大于杭子梢、白茅、蘆葦、合萌的生物量(P<0.05)。蘆竹、白茅、美人蕉、千屈菜四種植物間無(wú)差異，蘆葦、菩提子、杭子梢、合萌四種植物間無(wú)差異。株高和冠幅的大小與生物量基本保持一致。在濕地植物選種的過(guò)程中，單獨(dú)種植時(shí)選擇蘆竹、美人蕉、千屈菜、白茅、菩提子這幾種生長(zhǎng)優(yōu)勢(shì)大的濕地植物比較有利?；旌戏N植時(shí)選擇蘆竹、美人蕉、千屈菜、菩提子這幾種競(jìng)爭(zhēng)優(yōu)勢(shì)強(qiáng)的濕地植物比較有利。

THE GROWTH AND COMPETITION AMONG Eight KINDS OF PLANTS IN WET GROUND IN THE RATIO OF NO3-/NH4+ TO 50/50

ABSTRACT
In this paper, the study of bamboo reed, reed, canna, Pu Tizi, thousands of dishes Qu,Hangzhou sub-Pins, together Meng, Imperata and other 8 species of wetland plant
growth and competition in the nutrient solutions of (NO3-/NH4+) 50/50. 1) 8 independent plants cultured under the same conditions that: The biomass of Arundo donax, Imperata cylindrical, canna is greater than the biological reed, Pu Tizi, Hangzhou sub-Pins, co-Meng (P <0.05).Arundo donax, Imperata cylindrical, Canna was no difference between the three plants, reeds, Pu Tizi, Hangzhou sub-Pins, co-Meng was no difference between the five plants. Height and crown size and biomass remained consistent. 2) 8 mixed planting species that: The biomass of Pu Tizi, Arundo donax, Canna, thousands of Qu Hangzhou cuisine is greater than the biological child shoot, Imperata cylindrical, reed, co-Meng (P <0.05). Arundo donax, Imperata cylindrical, canna, four plant thousands of flexion did not differ between food, reed, Pu Tizi, Hangzhou sub-Pins, co-Meng was no difference between the four plants. Height and crown size and biomass remained consistent. In the selection of wetland plants, The selection of individual plant of Arundo donax, Canna, thousands of flexion vegetables, Imperata, Pu Tizi big advantage of these types of growth and more favorable wetland plants. The selection of mixed planting of bamboo reed, canna, thousands of flexion vegetables, Pu Tizi strong competitive advantage of these types of wetland plants more favorable.

Key words   Canna, Arundo donax, biomass
