摘　　要：[目的]针对宁夏河套灌区的生态气候和生产条件探讨该地区蓖麻的高产栽培技术体系。[方法]对蓖麻不同种植密度、不同整枝方法,氮磷肥使用量以及对蓖麻的生长发育情况进行观测与研究。[结果]适宜的蓖麻种植密度为784株/0.0667hm2,其株行距85cm×100cm;适宜的施氮量为纯N12kg/0.0667hm2;适宜的施磷量为纯P2O58kg/0.0667hm2;[结论]宁夏灌区栽培的优良蓖麻品种淄蓖麻2号的高产栽培模式为:选用良种、适期播种、保墒播种、覆膜栽培、间种套种、合理稀植、合理施肥、间苗补苗、控水灌溉、中耕培土、科学整枝、防治虫病、及时收获,且平均产量达15.33kg/hm2。[Objective]The aim to explore the region＇s high-yielding cultivation technology system for the eco-climatic and production conditions of Hetao Irrigation District in Ningxia.[Method]The different planting densities on the castor-oil plant,the different pruning methods,the use of nitrogen and phosphorus as well as castor-oil plant growth and development were observed and researched.[Result]The suitable density of castor plant was 784/0.066 7 hm2,which Zhu Xingju 85 cm×100 cm;appropriate amount of nitrogen for the pure N 12 kg/0.066 7 hm2;optimum P application rate for pure P2O5 8 kg/0.066 7 hm2.[Conclusion] Ningxia irrigated cultivation of the fine varieties of castor No.2 high-yield cultivation model：selection of seeds,sowing,water retention sowing,laminating cultivation,inter-species inter-planting,reasonable Sparse,rational fertilization,thinning Bumiao,control of water for irrigation,intertilling earthing up,scientific pruning,control pests,and diseases,harvest time and the average yield was 15.33kg/hm2.
