玉米生育期的长短与哪些原由相关?
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">玉米生育期指从播种到籽粒成熟所经历的天数,<span style="color: black;">亦</span><span style="color: black;">便是</span>玉米的生长周期,<span style="color: black;">通常</span>为80至120天不等。<span style="color: black;">那样</span>影响玉米生育期长短的<span style="color: black;">原因</span>有<span style="color: black;">那些</span>呢?</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">品种</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">不同品种的玉米生育期有所不同。<span style="color: black;">通常</span><span style="color: black;">来讲</span>,早熟玉米生育期短,中、晚熟玉米生育期相对较长。<span style="color: black;">因此呢</span>,在<span style="color: black;">选取</span>玉米品种时,要<span style="color: black;">按照</span><span style="color: black;">实质</span>种植区域的气温、降水<span style="color: black;">状况</span>等<span style="color: black;">原因</span>,结合<span style="color: black;">自己</span>的栽培经验和产量需求做出科学的<span style="color: black;">选取</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">温度</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">同一品种在不同的温度下,生育期长短<span style="color: black;">亦</span>不同。品种成熟所需的积温是相对稳定的,同一品种在积温较低的区域生育期相对较长,成熟期会有所延长,而在积温较高的区域,生育期相对较短,成熟期会有所缩短。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">日照</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">光是玉米生长的<span style="color: black;">要紧</span>环境<span style="color: black;">原因</span>之一,充足的光照<span style="color: black;">能够</span>促进植株的光合<span style="color: black;">功效</span>,加速养分的吸收和转化,<span style="color: black;">从而</span>缩短生育期。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">水分</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">适量的水分滋润土壤,保持植株正常生长<span style="color: black;">必须</span>的水分,对<span style="color: black;">加强</span>玉米产量和缩短生育期都有积极的影响。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">土壤</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">土壤是玉米生长<span style="color: black;">生长</span>的<span style="color: black;">基本</span>,土壤的肥力、深度以及理化性质等都会影响玉米的生长周期。<span style="color: black;">通常</span><span style="color: black;">来讲</span>,土壤肥沃、排水良好、pH值适宜的<span style="color: black;">地区</span>玉米长得更好,生长周期<span style="color: black;">亦</span>相对较短。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">种植密度</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">种植密度对玉米的生长<span style="color: black;">生长</span><span style="color: black;">亦</span>有影响。过于稠密的种植可能<span style="color: black;">引起</span>玉米叶片、根系生长不良,<span style="color: black;">增多</span>生长周期。</p>
