| 摘 要： | 研究施用不同浓度的氰氨化钙对花生生长和产量以及经济效益的影响.通过田间试验,在相同环境条件下,研究不同浓度梯度的氰氨化钙肥对花生产量和效益的影响.结果表明:适量施氮能促进花生的生长发育,增加地上部干物质积累.增加苗期根瘤数,提高花生荚果产量.但是过多施氮反而会使经济系数降低,还会导致荚果产量下降.该新型氰氨化钙肥安全有效用量为75～225 kg/hm2,在150kg/hm2用量时可获得最优农艺性状指数和最高经济效益.德国产新型氰氨化钙肥是花生较为理想的肥料.

| Abstract: | The research aimed to study the influences of Calcium cyanamide concentration on the peanut's growth and yield and economic benefit. Through the test in the field, the influences of the different concentration gradient of Calcium cyanamide on peanut's yield and economic benefit were studied in the same environmental condition. The right amount of Nitrogenous fertilizer could promote peanut's growth, increase the accumulation of the dry material upside the ground and the number of nodule in the stage of the ... |
