【摘要】 本文探讨了花魔芋切块栽培的主要农艺措施的优化组合。结果表明:0．5-1．5kg 的魔芋球茎均适于切块(每块0．25kg)作种用;其栽培密度以60000-90000株／hm2,堆肥以 75000-112500kg/hm2,过磷酸钙以750-1125kg／hm2,菜油饼肥以750-2250kg／hm2,尿素小于 450kg／hm2及氯化钾以450-600kg／hm2为宜。最优处理组合为:种薯7．5kg、密度90000株／ hm2、堆肥112500kg／hm2、尿素450kg／hm2、过磷酸钙1125kg／hm2、菜油饼2250kg／hm2及氯化钾 450kg／hm2。更多还原

【Abstract】 The optimum combinations of the major agronomic cultivation measures by using the sliced corms of Amorphophallus konjac koch were studied in this study by field experiments. The results show that when using corms weighting about 0.5 - 1. 5kg as seed material, with a cultivation density of 60000 - 90000 plants per hm2, the optimum fertilizer level are farmyard manure 75000-112500kg/hm2, superphosphate 750 -2250kg/hm2, cake fertilizer of rapeseeds 750-2250kg/hm2, urea 450kg/hm2 and potassium chloride (kcl) 450-600kg/hm2. We, however, got the best yield when we use 0. 5kg corms as seed material with the crop density of 90000 plants per hm2 and the fertilizer amount of farmyard manure 112500kg, urea 450kg, superphosphate 1125kg, cake fertilizer of rapeseeds 2250kg and KC1 450kg per hm2.更多还原
