<P align=center><FONT face="Times New Roman">彩色马蹄莲的栽培要点<p></p></FONT></P>
<P >一、生长习性<p></p></P>
<P >彩色马蹄莲属天南星科马蹄莲属,是多年生的球根花卉。花色有白色、黄色、粉红色、红色、紫色。盛花期<FONT face="Times New Roman">3</FONT>—<FONT face="Times New Roman">4</FONT>个月。喜温暖、湿润、光线充足。要求排水良好、肥沃疏松或略带粘性的土壤,土壤<FONT face="Times New Roman">pH</FONT>值应在<FONT face="Times New Roman">6</FONT>—<FONT face="Times New Roman">6</FONT>.<FONT face="Times New Roman">5</FONT>之间。<p></p></P>
<P >二、种植管理<p></p></P>
<P ><FONT face="Times New Roman">1</FONT>、种球选择:种植彩色马蹄莲,需选择<FONT face="Times New Roman">1</FONT>—<FONT face="Times New Roman">3</FONT>年生的种球<FONT face="Times New Roman">(</FONT>种过<FONT face="Times New Roman">3</FONT>年以上的种球,易传染病毒,并且产量和品质下降<FONT face="Times New Roman">)</FONT>,种植深度至少为<FONT face="Times New Roman">5</FONT>厘米,花期需充足的光照,否则花色浅淡。<p></p></P>
<P ><FONT face="Times New Roman">2</FONT>、温度:花生长期内,温室内的空气温度应在<st1:chmetcnv w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="False" SourceValue="25" UnitName="℃"><FONT face="Times New Roman">25</FONT>℃</st1:chmetcnv>以下,土壤温度<st1:chmetcnv w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="False" SourceValue="23" UnitName="℃"><FONT face="Times New Roman">23</FONT>℃</st1:chmetcnv>以下,理想的日间温度为<FONT face="Times New Roman">18</FONT>—<st1:chmetcnv w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="False" SourceValue="25" UnitName="℃"><FONT face="Times New Roman">25</FONT>℃</st1:chmetcnv>,夜间为<FONT face="Times New Roman">12</FONT>—<st1:chmetcnv w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="False" SourceValue="18" UnitName="℃"><FONT face="Times New Roman">18</FONT>℃</st1:chmetcnv>。高温会使植株抗性减弱。注意通风。夜温低有助于粉色或红色品种着色,对黄色品种影响不大。温度低于<st1:chmetcnv w:st="on" TCSC="0" NumberType="1" Negative="False" HasSpace="False" SourceValue="12" UnitName="℃"><FONT face="Times New Roman">12</FONT>℃</st1:chmetcnv>,则会降低花的产量及茎的长度。<p></p></P>
<P ><FONT face="Times New Roman">3</FONT>、浇水:马蹄莲喜水,生长期要有规律的浇水,但也不能过量,否则可能引起烂根。浇水应在早上浇,如果天气太热则最好晚上浇水。<p></p></P>
<P ><FONT face="Times New Roman">4</FONT>、施肥:有机肥或缓释肥对马蹄莲的生长很有好处,每隔一段时间,追肥一次。以磷钾肥为主,少施氮肥,因为氮肥促使营养生长,降低植株抵抗力。<p></p></P>
<P ><FONT face="Times New Roman">5</FONT>、马蹄莲开花需要充足光照:光照影响花的着色及植株健壮。过度遮荫及光照不足会导致花色浅淡和产量下降,所以冬季生产彩色季马蹄莲应注意补光。<p></p></P></DIV> |
