摘要
通过模拟试验及￣（１５）Ｎ追踪技术，研究了ＣＣＣ（氯化氯代胆碱）浸种对黄土高原旱地小麦水肥效应影响的机理。结果表明：１％ＣＣＣ浸种可使土壤深层（７０ｃｍ以下）根的重量增加８６．４％，并可提高旱地小麦再生新根的能力达２０％以上，对追施氮肥的利用能力较对照高２０％，产量提高了１６．４％。可见对旱地小麦使用ＣＣＣ浸种，不仅可以提高小麦利用土壤深层储水的能力，同时能增强春季降水后再生新根的能力，是提高黄土高原旱地小麦水肥利用率的一条新途径。
The effects of applying CCC solution to wheat seed soaking upon the water and fertil-izer use efficiency of dryland winter wheat are analyzed based on the simulating experiment andthe15N-trance technique.The results indicate that the application of 1%CCC solution to seedsoaking can increase the weight of root in deep soil layer(below 70 cm) by 86.4%,To add ni-trogen fertilizer with the spring rain. seed soaking in CCC solution can increase the ability ofwheat root regeneration and nitrogen utilization by 20%higher than that of the contrast.and itcan increase wlieat seed production hy 16.4%. Thus. it is an effective measure to raise the waterand fertilizer tise efficiency on dryland winter wheat by the application of soaking seed in CCC so-lution in connection with nitrogen fertilizer application in spring rain.
