Abstract
[Objective] The purpose was to discuss the suitable planting density of castor beans during its base construction in Anshun City,Guizhou Province,and provide a guidance for realizing its standardized cultivation during its domestication and breeding.[Method] Castor beans introduced from Chendu.Five planting density,5 130(choosing as CK),6 825,8 530,10 254,11 955 plants/hm2,were designed to carried out by randomized block design with 3 repeated,line spacing 150 cm,plant spacing 130,98,78,65 and 56 cm respectively in 2011.The test region area was 588.6 m2.[Result] The later period of vegetative growth and reproductive growth of castor beans had a trend in advance along with planting density in a certain range.Castor beans's biological characteristics and economic indices showed better when planting density was 6 825 and 8 530 plants/hm2,and its yield were all more than CK by 10%.[Conclusion] The suitable planting density and line spacing of castor beans under medium and lower grade soil fertility is 6 825 and 8 530 plant/hm2,and 150 cm in Anshun City,Guizhou Province.
