冀西北坝上地区不同萝卜品种的养分吸收特性比较
Comparative studies on nutrient absorption characteristics of different radish varieties in the northwest area of Hebei province
摘要
Abstract
A field experiment was conducted to study the nutrients absorption characteristics of six radish varieties in the northwest area of Hebei province. The results indicate that the root yields of the varieties, Chun Guan 35 and Chun hui are the highest, and the yield of Chun xue-sheng is the lowest. There are significant differences among the N, P and K accumulations and distributions in different radish varieties, the varieties of Chun lei, Chun guan35 and Chun hui have the largest accumulations of N, P2O5 and K20, respectively, and the accumulations of the other two nutrients and as well as the PFP are also higher than those of the other three varieties; The N accumulations of Chun guang and Chun xue-sheng are the lowest and the accumulations of P2O5 and K2O of Chun guan are the lowest. The varieties of Chun guang and Chun guan have higher production efficiency of nutrients and dry matter. In conclusion, Chun hui, Chun guan 35 and Chun lei have high nutrients use efficiencies, while Chun xue-sheng has low nutrients use efficiencies, and Chun guang and Chun guan have higher physiological use efficiencies of the nutrients.关键词
