摘要
为宁海及类似地区青花菜定额制施肥方案的优化及应用提供科学依据,通过大田小区试验研究养分减量条件下不同肥料及其运筹对青花菜产量和效益的影响。结果表明:不同施肥处理总产量差异不显著,但以减肥17.6%的配方肥(N-P 2 O 5-K 2 O为20-15-10)处理和减肥20.3%的缓释肥(N-P 2 O 5-K 2 O为13-4-8)处理产量高于均衡肥(CK,N-P 2 O 5-K 2 O为15-15-15)处理,产量分别为1271.1 kg/667m^2和1252.6 kg/667m^2;效益以减肥23.4%的配方肥处理最优,为4468元/667m^2,减肥21.6%的缓释肥(N-P 2 O 5-K 2 O为20-10-10)处理和减肥17.6%的配方肥处理次之,减肥20.3%的缓释肥处理与CK的效益基本持平。基于化肥定额制,化肥总养分减量17.6%~23.4%的条件下,配方施肥和缓释肥施用均能很好地实现化肥减量增效目的。
The effects of different fertilizers and its quotas under reduction of nutrient condition on yield and benefit of broccoli are studied by small and big areas of fields to provide the scientific basis for optimization and application of quota fertilization scheme for broccoli in Ninghai and similar areas.Result:There is no obvious difference in total yield of broccoli among different fertilization treatments.The yield of broccoli under reduction of 17.6%formula fertilizer treatment(20-15-10 of N-P 2 O 5-K 2 O)and under reduction of 20.3%slow release fertilizer treatment(13-4-8 of N-P 2 O 5-K 2 O)is higher than that of CK treatment(15-15-15 of N-P 2 O 5-K 2 O),respectively 1271.1 kg/667m^2 and 1252.6 kg/667m^2.The benefit of broccoli under reduction of 23.4%formula fertilizer treatment is the best(4468 Yuan/667m^2),followed by reduction of 21.6%slow release fertilizer treatment(20-10-10 of N-P 2 O 5-K 2 O)and reduction of 17.6%formula fertilizer treatment.The benefit of broccoli under reduction of 20.3%slow release fertilizer treatment basically equals to CK.Formula fertilizer and slow release fertilizer both can better achieve the goal of reducing amount and improving efficiency under reduction of 17.6%-23.4%chemical fertilizer nutrient based on fertilizer quota system.
