適當遮陰：雖然說太陽花叫jiao太tai陽yang花hua，開kai花hua時shi是shi需xu要yao充chong足zu的de光guang照zhao的de，可ke是shi當dang太tai陽yang花hua開kai花hua過guo後hou，如ru果guo遇yu到dao開kai花hua後hou陰yin天tian的de時shi候hou，太tai陽yang花hua開kai花hua的de時shi間jian會hui更geng長chang一yi些xie，很hen多duo花hua朵duo會hui開kai花hua到dao傍bang晚wan才cai開kai敗bai。因yin此ci為wei了le能neng夠gou讓rang太tai陽yang花hua開kai花hua時shi間jian更geng長chang一yi些xie，我wo們men可ke以yi在zai太tai陽yang花hua開kai花hua後hou，適shi當dang給gei太tai陽yang花hua遮zhe陰yin一yi些xie，一yi般ban遮zhe陰yin可ke以yi在zai30～40%左右就好，這樣做的效果會比暴曬的太陽花開花時間長2～3個小時。
要想讓太陽花開(kai)花(hua)時(shi)間(jian)更(geng)長(chang)一(yi)些(xie)，從(cong)春(chun)季(ji)開(kai)到(dao)秋(qiu)季(ji)，首(shou)先(xian)我(wo)們(men)要(yao)讓(rang)太(tai)陽(yang)花(hua)有(you)充(chong)足(zu)的(de)陽(yang)光(guang)。因(yin)此(ci)我(wo)們(men)可(ke)以(yi)把(ba)太(tai)陽(yang)花(hua)養(yang)在(zai)充(chong)足(zu)的(de)陽(yang)光(guang)下(xia)，如(ru)果(guo)是(shi)在(zai)室(shi)外(wai)養(yang)，我(wo)們(men)可(ke)以(yi)把(ba)太(tai)陽(yang)花(hua)養(yang)在(zai)充(chong)足(zu)的(de)陽(yang)光(guang)就(jiu)好(hao)。如(ru)果(guo)是(shi)在(zai)室(shi)內(nei)養(yang)，我(wo)們(men)要(yao)把(ba)太(tai)陽(yang)花(hua)養(yang)在(zai)南(nan)邊(bian)的(de)陽(yang)台(tai)上(shang)，這(zhe)樣(yang)太(tai)陽(yang)花(hua)開(kai)花(hua)時(shi)，微(wei)風(feng)徐(xu)來(lai)，滿(man)室(shi)飄(piao)香(xiang)。而(er)且(qie)在(zai)這(zhe)樣(yang)的(de)環(huan)境(jing)下(xia)，太(tai)陽(yang)花(hua)會(hui)不(bu)徒(tu)長(chang)，開(kai)花(hua)多(duo)又(you)鮮(xian)豔(yan)。
