注意時令草花(hua)種植的問題

選擇草(cao)(cao)花(hua)種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)時，應選擇籽粒(li)飽(bao)滿的(de)新鮮種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)。播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)前，應在(zai)冷(leng)水(shui)(shui)或(huo)溫水(shui)(shui)中(zhong)浸泡(pao)(pao)半(ban)天(tian)。在(zai)家(jia)種(zhong)(zhong)(zhong)(zhong)(zhong)草(cao)(cao)、種(zhong)(zhong)(zhong)(zhong)(zhong)花(hua)時，花(hua)盆(pen)經常用(yong)爛葉土、細砂等土填充(chong)花(hua)盆(pen)，攤鋪(pu)后(hou)即可(ke)種(zhong)(zhong)(zhong)(zhong)(zhong)植。灌水(shui)(shui)后(hou)，一般采用(yong)“浸泡(pao)(pao)盆(pen)”的(de)方(fang)法(fa)使盆(pen)地濕潤，清(qing)明期間春(chun)季不建議播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)，一般草(cao)(cao)花(hua)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)的(de)方(fang)法(fa)是播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)、鉆孔(kong)(kong)或(huo)按(an)需播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)。對于翠菊(ju)、荷(he)蘭菊(ju)花(hua)等花(hua)卉(hui)(hui)，由于種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)小，適宜采用(yong)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)方(fang)式(shi)，如晨(chen)光、余美仁(ren)等屬于直根(gen)花(hua)卉(hui)(hui)。采用(yong)鉆孔(kong)(kong)播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)的(de)方(fang)法(fa)，紫百合、甘藍等大(da)型種(zhong)(zhong)(zhong)(zhong)(zhong)子(zi)可(ke)采用(yong)按(an)需播(bo)(bo)(bo)(bo)種(zhong)(zhong)(zhong)(zhong)(zhong)的(de)方(fang)式(shi)。

時(shi)令草(cao)花苗期如何進行管(guan)理?

草花(hua)種子發有成小苗后，澆(jiao)水應見(jian)干(gan)見(jian)濕(shi)，且(qie)不能使土表積(ji)水。澆(jiao)水時間務必選在(zai)早晨。

露地播種，采用(yong)控制(zhi)播種期(qi)的(de)方(fang)法，以確保上(shang)午10時(shi)及(ji)下午2時(shi)左(zuo)右，幼(you)苗(miao)處于適(shi)生長(chang)溫(wen)(wen)度(du)，中午可(ke)采用(yong)遮(zhe)陰(yin)、.通風、流水(shui)等方(fang)法，降(jiang)低環(huan)境溫(wen)(wen)度(du)。溫(wen)(wen)差大的(de)地區，夜間需(xu)(xu)加保護(hu)措(cuo)施。保護(hu)地白天(tian)溫(wen)(wen)度(du)超過25℃以上(shang)需(xu)(xu)要換氣.換氣口(kou)應(ying)遠離(li)幼(you)苗(miao)，以免幼(you)苗(miao)受害。一(yi)二年(nian)生草花多數都需(xu)(xu)移植(zhi)，移植(zhi)床(chuang)土可(ke)用(yong)播種土，亦可(ke)用(yong)園土加腐熟的(de)堆肥。移植(zhi)一(yi)般在陰(yin)天(tian)或傍晚進行(xing)，間距依苗(miao)大小(xiao)而定，移植(zhi)后應(ying)遮(zhe)光5一(yi)7天(tian)，促其成活。

露天育苗(miao)(miao)時.比較容易發生幼(you)苗(miao)(miao)立(li)枯病，可將發病部分連(lian)同周圍植株一起(qi)挖除，補充清潔(jie)的土壤后，使用相應的藥劑。葉上(shang)病害可在真展(zhan)開后，依照常規方法防治(zhi)。

時(shi)(shi)令草花在定植(zhi)取苗時(shi)(shi)，根(gen)部要盡(jin)量帶(dai)土(tu)挖(wa)取.并小心搬運，不要讓根(gen)土(tu)分離。種植(zhi)時(shi)(shi)，挖(wa)穴要大些，不宜過淺或過深，保持比原植(zhi)株根(gen)頸(jing)處稍深一點即(ji)可。種后用指頭(tou)壓緊，使(shi)花卉植(zhi)株的根(gen)系(xi)與土(tu)壤(rang)比較好的接(jie)觸(chu)，然后及時(shi)(shi)的澆透水。此后I周內(nei)均應實現比較好的灌水，促其成活(huo)。
