不同水分条件下沙地花生的根冠发育动态分析

Dynamic Analysis on Root/Shoot Development of Peanut Under Different Water Regimes

通过对不同水分条件下花生生长过程中根冠干物质累积动态的试验研究和分析，可知花针期在花生生长过程中属敏感期，如在此期缺水，根冠生长均受到抑制，根冠干物质固有的累积比例和生长速度均会发生变化。此项工作为进一步研究花生最佳根冠比和花生的适时适量灌溉提供了依据。

Root/shoot development of peanut under different water regimes was studied andanalyzed dynamically. The results showed that the stage of the flower needle is sensitiveduring peanut lifetime. Lacking water in this period will limit the growth of root and shoot,the dry-weight proportion and growing rate will also be changed. The further research onthe best ratio of root/shoot and suitable irrigation method can be expected.
