- 摘要:
- 为提高肥料利用效率,明确化控施肥下的玉米生产效益,以传统农民施肥模式为对照,研究了缓释肥机械施用模式的玉米产量特性和生产效益。结果表明:与农户传统施肥相比,机械施用控释肥产量增加10.19%,氮肥偏生产力提高4.40%;秃尖减少44.31%、穗长与行粒数分别增加9.40%和14.84%;农户传统施肥总投入为3 865.05元?hm-2,总收入8 806.10元?hm-2,纯收入4 941.05元?hm-2;机械施用控释肥总投入3 467.25元?hm-2,总收入9 703.70元?hm-2,实现纯收入6 236.45元?hm-2,较农户传统施肥增收1 295.40元?hm-2。可见,与农户传统施肥相比,机械施用控释肥的氮肥利用效率更高,稳产性更强,更利于机械化收获。
- Abstract:
- In order to improve the efficiency of fertilizer utilization,and to clarify the maize production efficiency under the chemical control,yield characteristics and productivity effect of controlled release fertilizer mechanical application model were studied using easant household traditional fertilization as the contrast.The results showed that compared with peasant household traditional fertilization,mechanical harvest yield of controlled release fertilizer mechanical application increased by 10.19%,and the nitrogen partial factor productivity increased by 4.40%; However,the length of bald tips decreased by 44.31 while the ear length and number of grains per row increased by 9.40% and 14.84% respectively; The total investment of peasant household traditional fertilization was 3 865.05 yuan?hm-2,with total income of 8 806.10 yuan?hm-2 and net benifit of 4 941.05 yuan?hm-2.The total investment of the controlled release fertilizer was 3 467.25 yuan?hm-2 while the total income and net was 9 703.70 and 6 236.45 yuan?hm-2 respectively,which was 1 295.40 yuan?hm-2 higher than the traditional fertilizer application.In conclusion,compared with the traditional fertilization of peasant households,the nitrogenous fertilizer applied in the controlled release fertilizer is more efficient and more stable,which is more conducive to mechanization.
