几种有机物料对连作黄瓜生长的影响

A Study on the Effect of the Rice Straw and Other Organic Materials on the Cucumber Growth of Continuous Cropping

将有机物料稻草、猪粪、锯木屑按 0 .5 %、1%和 2 %用量施入已产生连作障碍的土壤 ,盆钵试验结果表明在连作黄瓜的不同生育期即 3叶期、5叶期和 7叶期 ,0 .5 %～ 2 %用量猪粪及 0 .5 %用量稻草能促进连作黄瓜生长 ,植株的株高、最大叶面积和干物重增加 ;而锯木屑和高用量稻草处理抑制连作黄瓜生长 ,植株的株高。

Different organic materials such as rice straw, wood dust and pig manure were used as continuous cropping soil. The study showed that pig manure and low usage rice straw, or wood dust and higher usage rice straw, can increase cucumber growth of continuous cropping of and increase height, leaf area and dry weight of cucumber seedling.
