安和香(xiang)芋(yu)呈紡錘形,表皮棕(zong)褐(he)色(se),橫切面灰(hui)白(bai)色(se)并密布棕(zong)紅色(se)檳榔花紋,肉質緊密,蒸煮后口感(gan)細膩粉糯,芋(yu)香(xiang)味濃郁。
安和香(xiang)芋(yu)內在品質(zhi)指(zhi)標控制范圍(wei)為:蛋(dan)白質(zhi)≥1.5g/100g,淀粉(fen)≥22g/100g,鈣≥120mg/kg。
安和香芋(yu)保護地(di)域范圍(wei)位(wei)于“五(wu)嶺”之一都龐(pang)嶺峽谷區域,三面(mian)環(huan)山,東(dong)面(mian)是狹長(chang)谷地(di)—“湘桂走廊(lang)”,該區域土(tu)壤以沙壤土(tu)為主,土(tu)質疏松,透氣性(xing)及排水性(xing)良好,特別(bie)適合球莖的安和香芋(yu)生長(chang)。
同(tong)時該區域溫(wen)和(he)濕潤,年平均(jun)(jun)氣溫(wen)17.7℃,年平均(jun)(jun)降(jiang)雨(yu)量1565mm;且晝(zhou)夜溫(wen)差(cha)大,安和(he)香(xiang)芋生長發育期晝(zhou)夜溫(wen)差(cha)均(jun)(jun)達到8℃以上,獨特的(de)地(di)理位置和(he)氣候條件能夠有效促(cu)進安和(he)香(xiang)芋球莖膨大發育。
種苗準備:安和香芋(yu)(yu)子(zi)芋(yu)(yu)明顯特征(zheng)(zheng)是(shi)子(zi)芋(yu)(yu)和母芋(yu)(yu)以細(xi)長似竹(zhu)根(gen)的根(gen)莖相連,故又(you)稱“竹(zhu)根(gen)芋(yu)(yu)”。每年2月份從安和香芋(yu)(yu)留種田中篩選(xuan)具備“竹(zhu)根(gen)芋(yu)(yu)”特征(zheng)(zheng),且(qie)主芽飽(bao)滿、無病蟲斑、無霉(mei)爛,長度10cm~15cm,單個重約50g的子(zi)芋(yu)(yu)留做芋(yu)(yu)種。
定植:對篩選好作為芋種(zhong)(zhong)(zhong)(zhong)的子(zi)芋進行催芽(ya),當(dang)芽(ya)頭似(si)雞嘴,根長(chang)一粒米時最適種(zhong)(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi),宜在3月中旬開(kai)始種(zhong)(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi),清明節(jie)氣前種(zhong)(zhong)(zhong)(zhong)完。開(kai)種(zhong)(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)溝,深度15cm~20cm,按種(zhong)(zhong)(zhong)(zhong)植(zhi)(zhi)(zhi)株距傾斜45°(芽(ya)朝下)排放,芋種(zhong)(zhong)(zhong)(zhong)宜按大小分開(kai)排種(zhong)(zhong)(zhong)(zhong),排放完畢后(hou)先用(yong)火土(tu)(tu)灰或草皮灰覆蓋在芋種(zhong)(zhong)(zhong)(zhong)上,再用(yong)細(xi)土(tu)(tu)二次覆蓋。定(ding)植(zhi)(zhi)(zhi)后(hou)淋水保持(chi)土(tu)(tu)壤濕潤。
覆膜:選用黑色環保型(xing)地膜(mo)(mo)(mo)(1.2m)每畝(mu)4kg~5kg覆蓋,要求廂面(mian)平整(zheng),泥(ni)土(tu)細(xi)碎,膜(mo)(mo)(mo)邊(bian)四周沿著(zhu)廂邊(bian)用泥(ni)土(tu)壓實(shi)。地膜(mo)(mo)(mo)覆蓋后應(ying)注意檢(jian)查,發現芽長出地面(mian)后,應(ying)及時(shi)(shi)破膜(mo)(mo)(mo),膜(mo)(mo)(mo)口寬約20cm,并用泥(ni)土(tu)壓實(shi)膜(mo)(mo)(mo)口,發現缺苗的應(ying)及時(shi)(shi)補上。追(zhui)肥時(shi)(shi)需揭開廂邊(bian)地膜(mo)(mo)(mo),施完后蓋上土(tu),然后再蓋上薄膜(mo)(mo)(mo),直到收獲挖(wa)收時(shi)(shi)再揭。
