Research on Fertilizer Effects on Confectionary Sunflower in Northwest Hebei of China
摘要
Abstract
[Objective] The aim was to study the fertilizer effects on confectionary sunflower in northwest Hebei of China. [Method] Fine excellent varieties were sampled to carry out a '3414' teat to study different N,P and K fertilization levels,so as to explore the optimum fertilization benefit and optimum fertilization combination of the new varieties. [ Result] K fertilizer had the largest effect on the yield of confectionary sunflower. The maximum yielding fertilization combination of conventional varieties was 71.7 kg/hm2 N,48.3 kg/hm2 P2OS and 68.4 kg/hm2,K20, under which the yield was 3 052.5 kg/hm2. The best fertilization combination for highest economic benefits was 67. 2 kg/hm2 N,50. 1 kg/hm2 P2O5 and 68.3 kg/hm2 K2O,under which the yield was 2 909.7 kg/hm2.The maximum yielding fertilization combination of hybrid varieties was 65.1 kg/hm2 N,66.5 kg/hm2 P2O5 and 154.4 kg/hm2 K2O, under which the yield was 3 302.4 kg/hm2. The best fertilization combination for highest economic benefits was 72.8 kg/hm2 N,57.8 kg/hm2 P2O5 and 138.7 kg/hm2 K2O,under which the yield was3 291.3 kg/hm2. [Conclu-sion] The research provides a scientific basis for the promotion and cultivation technology of the new varieties.关键词
