越夏叶菜种植有技巧——“种得好”视频直播第3期即将上线！
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><strong style="color: blue;"><span style="color: black;">夏季，是叶菜的种植旺季</span></strong></span><span style="color: black;">。</span><span style="color: black;">老话说 “三天不见青，肚里冒火星”，说的便是夏天三天不吃青菜，就会上火，有些地区的居民在夏天<span style="color: black;">更加是</span>对青菜<span style="color: black;">喜欢</span>得不得了。叶菜生<span style="color: black;">长时间</span>短，种植技术相对简单，<span style="color: black;">亦</span>深受广大种植户的欢迎。然而，越夏叶菜并<span style="color: black;">欠好</span>种，死棵现象、病虫害、徒长、抽薹等频发，令想要创收的种植户有点灰心。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;"><span style="color: black;">那样</span>，到底该怎么破解这些棘手的种植<span style="color: black;">困难</span>呢？</span></span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><strong style="color: blue;"><span style="color: black;">死棵现象：</span></strong></span><span style="color: black;">重点</span>是雨水灌棚、病虫害较多<span style="color: black;">引起</span>的。<span style="color: black;">因此呢</span>，<span style="color: black;">必定</span>要严防雨水进棚。下雨前，<span style="color: black;">首要</span>要对旧棚膜进行<span style="color: black;">检测</span>，<span style="color: black;">发掘</span>有窟窿，就要<span style="color: black;">即时</span>修补。其次，在下雨前把拱棚两侧的薄膜放下，以防雨水进棚。<span style="color: black;">倘若</span>有大雨来临，为了保险起见，可在拱棚两侧培上一层土，再把两侧薄膜压在土的外面，<span style="color: black;">这般</span>就能<span style="color: black;">保准</span>雨水不进棚。<span style="color: black;">倘若</span><span style="color: black;">因为</span>防护<span style="color: black;">欠妥</span><span style="color: black;">引起</span>雨水进棚后，应<span style="color: black;">即时</span>做好排水工作，并<span style="color: black;">即时</span>浇清水，最好再划锄一遍，<span style="color: black;">增多</span>土壤的通透性，防治沤根死棵现象。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><strong style="color: blue;"><span style="color: black;">病虫害：</span></strong></span><span style="color: black;"><span style="color: black;">重点</span>是病源较多、寄主广泛、高温高湿等<span style="color: black;">原因</span><span style="color: black;">导致</span>的。<span style="color: black;">例如</span>，在棚内残留的枯枝烂叶上面都带有<span style="color: black;">海量</span>的病原<span style="color: black;">胞子</span>，<span style="color: black;">作为</span>病害的传染源。对此，在上茬作物拔园后，要<span style="color: black;">即时</span>清理园区，还要<span style="color: black;">即时</span>清除棚内外的杂草，尤其是这些杂草寄居的病虫多，易<span style="color: black;">经过</span>这些害虫传带的方式把病害传染给棚内的作物。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">徒长：</span></strong><span style="color: black;"><span style="color: black;">棚内通风降温<span style="color: black;">办法</span>不力，植株极易<span style="color: black;">显现</span>旺长现象。<span style="color: black;">因此呢</span>，调控好棚内温度，如采用<span style="color: black;">晌午</span>前后用遮阳网遮阴及加大通风、经常浇小水等<span style="color: black;">办法</span>，使温度<span style="color: black;">掌控</span>在</span>18～22℃，保持土壤湿润，促进叶菜生长。</span></p>
