不同种植密度对蓖麻生长发育及产量的影响
Effects of Different Planting Density on Growth and Development and Yield of Castor Beans(Ricinus communis L.)
摘要
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/hm3, 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, Cuizhou Province.关键词
