春播时间对胡萝卜产量和品质的影响
|
摘要
以黑田五寸为试验材料,设置5个播期,探究太原地区春季播期对胡萝卜产量和品质的影响。结果表明,随着播种时间的推迟,各播期胡萝卜的抽薹率呈下降趋势,合格根比例为4月5日播种的最高,根形指数为4月1日,4月10日播种的表现较优,产量为4月5日和4月10日播种的显著高于其他播期;肉质根胡萝卜素含量为4月10日播种的相对较高。综合分析,春季胡萝卜播种应安排在4月5—10日。
Five sowing times were designed to study the effects of sowing time in spring on the yield and quality of carrots in Taiyuan region by using Heitianwucun as the experimental materials. The results showed that with the delay of sowing time, the bolting rates of the carrots tended to decline. The proportion of qualified root was the highest on April 5, and the root shape index showed better performance on April 1, 10, and the yield was significantly higher on April 5 and April 10 than on other sowing dates. Fleshy root carotene content was relatively high on April 10. Under the condition of the experiment, planting carrots should be arranged during April 5 to 10 in the spring.
