產地環境

羅田縣位(wei)于(yu)大(da)別(bie)山南麓(lu)，總面積321萬(wan)畝，屬亞熱帶季(ji)風(feng)區(qu)(qu)(qu)，氣(qi)候溫(wen)(wen)(wen)和，陽(yang)光充足，雨量充沛，光水(shui)熱同(tong)步，自(zi)然條(tiao)件(jian)(jian)很好。年平均溫(wen)(wen)(wen)度(du)16.4℃，降雨量1300-1600毫米，無霜期(qi)(qi)181-231天(tian)，極(ji)為(wei)(wei)適宜甜(tian)(tian)(tian)柿生(sheng)長(chang)(chang)發(fa)(fa)育(yu)要求。羅田不(bu)僅具有適宜甜(tian)(tian)(tian)柿生(sheng)長(chang)(chang)發(fa)(fa)育(yu)的(de)基(ji)本氣(qi)候條(tiao)件(jian)(jian)，而(er)且由于(yu)地(di)勢(shi)、地(di)形(xing)(xing)、地(di)貌和森林(lin)植被的(de)自(zi)然調節作用，形(xing)(xing)成(cheng)(cheng)更具獨特優(you)勢(shi)的(de)區(qu)(qu)(qu)域環(huan)境。一是地(di)勢(shi)北高(gao)南低(di)，對氣(qi)候資源可以(yi)進行(xing)再分(fen)配，自(zi)行(xing)調節，使甜(tian)(tian)(tian)柿生(sheng)長(chang)(chang)發(fa)(fa)育(yu)期(qi)(qi)內溫(wen)(wen)(wen)室(shi)巨(ju)變較小。二(er)是地(di)形(xing)(xing)地(di)貌差異大(da)，小氣(qi)候小環(huan)境較多(duo)，適宜栽植甜(tian)(tian)(tian)柿的(de)面積大(da)。三是森林(lin)覆蓋率(lv)高(gao)，達(da)到68.8%，植被條(tiao)件(jian)(jian)好，自(zi)然生(sheng)態(tai)優(you)良(liang)，對提(ti)高(gao)甜(tian)(tian)(tian)柿果實(shi)光澤(ze)，降低(di)果皮(pi)厚度(du)都十分(fen)有利(li)。四是晝夜溫(wen)(wen)(wen)差大(da)，有利(li)于(yu)果實(shi)的(de)形(xing)(xing)成(cheng)(cheng)。羅田柿產(chan)區(qu)(qu)(qu)溫(wen)(wen)(wen)差比平原地(di)區(qu)(qu)(qu)要大(da)，甜(tian)(tian)(tian)柿果實(shi)膨大(da)成(cheng)(cheng)熟期(qi)(qi)為(wei)(wei)7-9月(yue)，其晝夜溫(wen)(wen)(wen)差一般都在10℃以(yi)上，比平原大(da)4℃以(yi)上，這(zhe)對柿果糖分(fen)轉化(hua)和營養積累極(ji)為(wei)(wei)有利(li)，是羅田甜(tian)(tian)(tian)柿品(pin)質優(you)良(liang)、味道鮮美的(de)一個重要原因。五是土(tu)壤(rang)適宜甜(tian)(tian)(tian)柿生(sheng)長(chang)(chang)，羅田土(tu)壤(rang)多(duo)為(wei)(wei)片麻巖風(feng)化(hua)形(xing)(xing)成(cheng)(cheng)的(de)沙(sha)壤(rang)土(tu)，透水(shui)、通(tong)氣(qi)性(xing)能良(liang)好，微(wei)酸性(xing)和中性(xing)，有利(li)于(yu)柿樹根系生(sheng)長(chang)(chang)，柿樹壽(shou)命長(chang)(chang)，盛果期(qi)(qi)長(chang)(chang)，豐(feng)產(chan)性(xing)好。
