高秆大穗型鲜食甜玉米栽培密度和优化施肥研究
Planting Density and Optimize Fertilization of Fresh Sweet Corn with High Stem and Big Ear
摘要
Abstract
[Objective] To explore efficient cultivation techniques that were suitable for Hainan soil type and varietal characteristic.[Method] With fresh sweet corn Thai sweet No.1 as the experimental material, different densities, different fertilizer cultivation experiments were done. [Result] The results showed that the Thai sweet No.1 in hainan was the most suitable planting density in 37500-45000 plants/hm2;The contribution of nitrogen, phosphorus and potash was that nitrogen was the largest, followed by phosphorus, finally was potassium;Nitrogen, phosphorus and potassium fertilizer rate and yield presented a yuan quadratic parabolic equation, and the equations were significantly;When P2 O5 , K2 O was 336, 160, 213 kg/hm2 , fertilizer proportion of N:P2 O5:K2 O =1.00:0.50:0.65, could obtain the best economic yield, ni-trogen, phosphorus and potassium fertilizer utilization rate and fertilizer efficiency was higher.[ Conclusion] The research results apply for cul-tivation of high stalk, fresh sweet corn varieties in Hainan middle fertile soil .关键词
