摘要
采用正交试验方法,对滴灌条件下侧柏的灌水次数、灌溉定额和氮磷质量分数比三因素组合方案进行了试验研究.结果表明,7—10月份,灌水次数6次/月、灌溉定额为12 m3/666.7 m2、m(N)∶m(P)=2.5时为最优组合方案,这为高速公路中分带侧柏滴灌节水节肥提供理论依据.
Was carried out to optimize composition experiment of three factors among the irrigation, times of irrigate, fitting of N and P fertilizer for the height of arborvitae under the condition of drip irrigation by cross experiment methods. The result indicates that the optimum combination of the three factors is at 6 times of irrigation, irrigation quota 12 m^3/666.7 hm^2, re（N） ：m（P） ratio 2.5. The result provides the theoretic perspective to save fertilizer and water for arborvitae of highway under drip irrigation.
