Effects of Different Planting Densities and Topdressing Fertilizer Levels on Yield of Coix lacroyma-jobi var.ma-yuen
摘要
Abstract
In order to ascertain the effects of different planting densities and topdressing fertilizer levels on the yield of Coix la-croyma-jobi var.ma-yuen, we carried out the orthogonal experiments with three factors (topdressing fertilizer level, nest row spacing, and seedling number per nest) and four levels, and the white-shell Coix lacroyma-jobi var.ma-yuen which was ordi-narily planted in Qianxinan prefecture was taken as the tested material .The results showed that planting density and topdressing fer-tilizer level had significant effect on the yield of Coix lacroyma-jobi var.ma-yuen.With the increase of topdressing fertilizer lev-el, the yield firstly increased to a significant difference , and then decreased to a certain extent .There were very significant differ-ences in the yield among different levels of nest row spacing and seedling number per nest .The treatment combination of A 3 B2 C4 (nest row spacing 80 cm ×80 cm, six seedlings per nest, topdressing urea 20 kg/667 m 2 ) obtained the best yield -increasing effect.关键词
