水分、pH值、光照对蓝蓟生长性状及产量的影响研究

在温室内进行土壤pH值、水分、光照的梯度处理，通过对性状指标及产量指标的测定与分析，了解各项环境因子对蓝蓟生长及产量的影响。在pH值6.5、湿润条件下最先出苗,其次为pH值6～8，再次是80％光照处理出苗，最后为干旱和60％光照处理出苗。植株生长到第9天开始测定植株苗期性状指标为：pH值6.0、湿润、光照正常情况，叶长...

Effects of Moisture, pH Value and Illumination on Growth, Yield and Quality of Echium Vulgare L.

It was used the gradient treatment of soil pH value,moisture and illumination inside the greenhouse.It was understood the effect of any environmental factors on growth and yield via determining and anlyzing on the character and yield indexs.The results showed that it was firstly seeding emergenc under the condition of pH value equaled to 6.5 and moist.pH value between 6 to 8 was followed,then were the 80% illumination treatments,the last one was dry and 60% illumination treatments.When plants grew on the ninth day,it was began to measure the character indexs of seeding.It showed that leaf length,width and hight were maxium when pH value equaled to 6.0,moist and normal illumination conditions.Testing seed results indicated that the maxium value of the thousand grain weight was 4.43 when the pH value was 6.5(115% of the control).,and the minium was 3.34 on dry condition.The maxium of single plant grain number was 1 635 under pH 6.0,and the minium was 913 on the dry conditon.The maxium of crud fat content was 24.60% on pH value 8.0,and the minium was 18.60% under 80% illumination.The results of statistical analysis were that the prerequisite on the growth of Echium vulgare L.were abundant light supply and moist soil.If it was meta acid,it was good at character and yield,however,meta alkaline was good at quality of Echium vulgare L.
