4 种育苗基质对辣椒幼苗生长的影响简

从市面上在售的4种基质中筛选出最适合辣椒工厂化育苗的基质。试验选用江苏柴米河、乌鲁木齐市禾宝、上海孙桥、米东丰禾源这4种基质，通过衡量不同时期幼苗的形态指标，如成苗的叶绿素相对含量、出苗率，幼苗株高和茎粗，幼苗的节间长度，幼苗的整齐度，幼苗的真叶数，幼苗的根冠鲜重比来衡量4种基质的优劣。试验结果表明，乌市禾宝基质对辣椒工厂化育苗出苗率的作用效果最好，江苏柴米河对辣椒幼苗的各个形态指标作用最好。4种基质中，上海孙桥由于出苗率最低且辣椒幼苗的形态指标最次，所以它对辣椒幼苗的作用效果最差。在辣椒工厂化育苗中，可以选择乌鲁木齐禾宝或者江苏柴米河作为辣椒的育苗基质。

Effect of 4 Substrates on Growth of Pepper Seedlings

The purpose is to select the most suitable substrate for pepper factory nursery from four substrates in the sale. Taking 4 substrates from Jiangshu, Urumqi, Shanghai, Midong as materials, morphological indicators of seedlings in different periods, such as the relative contents of chlorophyll of adult seedling, emergence rate, seedling height and stem diameter, internode length and uniformity of seedlings, leaf number, fresh weight ratio of root to canopy were determined. The experimental results showed that Hebao from Urumqi had the best effect on pepper factory nursery seedling emergence, and Chai Mihe from Jiangsu had good performance in the various morphological indicators of seedlings. Due to the lowest germination rate and the worst effects on morphological indicator, Sunqiao from Shanghai is the worst substrate. In chili factory nursery the Hebao from Urumqi or the Chai Mihe from Jiangsu can be chosen as seedling substrates.
