为了探讨水肥耦合作用下,不同比例的不同草炭对植物生长的影响.以小白菜为供试植物,通过4个灌水水平和施肥与不施肥两个肥分水平处理,采用了石河子草炭与加拿大草炭不同添加量处理在温室里进行盆栽试验,试验结果表明:施肥与不施肥对小白菜根系发育没有明显影响,而草炭的添加有利于其根系的发育和叶绿素的增加.在50%(对照饱和田间持水量为100%)灌水水平下,草炭对小白菜的生长反而起抑制作用,降低了其地上部鲜重,随着灌水量的增加,草炭的整体优势得以发挥,当灌水量达到100%时、125%时,草炭保水的优势发挥了,8%石河子和5%加拿大草炭混合处理的明显优于对照,地上部鲜重达到了对照4倍多.因此,8%石河子...

The addition of different ratio of peat to the soil affecting on the growth of plant under the coupling of water and fertilizer was discussed. The cabbage was taken in this experiment, and four water levels and two fertilizer were designed. The different addition of Shihezi peat and Canada peat affected on the growth of the cabbage in pot experiment in the greenhouse. The results show that fertilizer and no fertilizer had not remarkable effect on root, but the addition of peat made for root Under the fifty percent of water level （the saturatio...
