蕉藕栽培模式研究

蕉藕生长期长，抗逆性强。通过对其栽培模式的研究，表明：在常耕地中，蕉藕＋玉米套作与红苕＋玉米套作、蕉藕净作与红苕净作，其亩产干物质的量在相应模式之间无明显差异，但玉米＋红苕套作、红苕净作的消化能明显高于玉米＋蕉藕套作和蕉藕净作；在非耕地中，蕉藕净作的干物质、消化能反而明显高于红苕净作的千物质消化能。因此，在常耕地中，宜采用红苕＋玉米套作，在非耕地中宜采用蕉藕净作。

Study on the cultivation model of Canna edulis

Canna edulis is a source of energy feed, which is a kind of herbaceous plants rich in starch.Our cultivation experiment results showed that Canna edulis had strong stress tolerance with a long growth period of 300 days; in normal cultivated cropland,there was no significance in dry matter yield per mu among the four cropping models, but the digestion energy yield of the nest cropping of sweet potato and corn was remarkably higher than that of nest cropping of Canna edulis and corn, and the digestion energy yield of sweet potato solo cropping was remarkably higher than that of Canna edulis solo cropping;in the non-cultivated land,the dry matter yield per mu of Canna edulis cropping was remarkably higher than that of sweet potato solo cropping,as well as the digestion energy. So, nest cropping of sweet potato and corn was proper in normal cultivated cropland, in the non-cultivated land, Canna edulis was fit for solo cropping.
