为探讨夏玉米双膜缓释配方肥料种肥异位同播施用方式及合理施用量,特安排本试验。结果表明:夏玉米种肥异位同播种肥间距20 cm和15 cm与间距10 cm、5 cm相比,产量差异达显著水平,种肥间距以15~20 cm为宜;夏玉米采用种肥异位同播方式,亩施用40%(28-6-6,其中16%缓释氮肥)双膜缓释配方肥料50 kg与农户习惯施用普通复合肥料相比,增产效果极显著,穗粒数和千粒重分别增加51.4粒和10.1 g,亩增产73.9 kg,增产率达13.1%,亩收入增加127.6元,增幅达18.5%。
In order to explore the summer maize double-film slow release formula fertilizer ectopic sowing the same way and a reasonable application rate, arrange this test. The results showed that the differences of yield between summer heterosis and sowing fertilizer of 20 cm and 15 cm and spacing of 10 cm and 5 cm were significant, and the spacing of seed fertilizer was 15 ~ 20 cm. Ectopic sowing mode, mu 40% (28-6-6, of which 16% slow-release nitrogen fertilizer) 50kg slow-release formula fertilizer and peasant farmers accustomed to using common compound fertilizer, the yield was significantly increased, the number of grains per spike And 1000-grain weight respectively increased by 51.4 and 10.1 g, yield increase of 73.9 kg, yield increase rate of 13.1%, and mu income increased by 127.6 yuan, an increase of 18.5%.
