【摘要】 根据农业系统工程学“最佳模拟配合”原理，采用“多元二次正交旋转组合设计”的方法，研究了豫西丘陵旱地小麦基本苗、施氮量、施磷量对产量的效应，结果证明：各因素对小麦产量的影响程度依次为氮肥、磷肥、基本苗，增施肥料是小麦增产的基础；豫西丘陵旱地小麦产量随磷肥的增施而增加，与氮肥施用量呈抛物线状，以 １５～１８ｋｇ／６６７ｍ ２ 最高；在其它微效和独效采用最佳水平时，每６６７ｍ ２ 的产量在 ３００ｋｇ 以上时应采取的农艺措施是施纯氮 １５～１８ｋｇ，纯磷 ６～７ｋｇ，基本苗１６～１９ 万株。更多还原

【Abstract】 The effects of the basic seedling, the quantity of nitrogenous fertilizer and phosphate fertilizer applied to the yield were studied by ‘Polly component quadratic spinning combination design’ with the principle of the best imitating combination in agricultural systems engineering in hilly dry land in the west of Henan. The results show that the effects of the factors mentioned above on the wheat yield were in the order as nitrogenous fertilizer,phosphate fertilizer and the basic seedling. Applying fertilizer is the basis of the wheat yield increasing. The wheat yield was increased with the phosphate fertilizer applied,and with the nitrogenous fertilizer following the parabola.The wheat yield was the highest when the quantity of nitrogenous fertilizer was 15 18kg/667m 2 in the test fields. For the yield of 300kg/667m 2 or more,the agricultural measures are that the 15 18kg/667m 2 nitrogen and 6 7kg/667m 2 P 2O 5 are applied,the basic wheat seedling is 160 190 thousands when others is the best.更多还原
