The results of two-year experiments of no-tillage rice cultivation with differ- ent dosages of nitrogen fertilizers showed that the numbers of effective panicles in N applica- tion plots were 15.38%～48.52% more high than those in CK plots and the dry weight of single plant as well as plant height increased with ascending application rate of nitrogen fer- tilizer.The ratio of N nutrient content in plant to total accumulated N absorption amount (on dry weight basis)from tillering stage to booting stage was 63... 二年不同氮肥用量的田间试验结果表明,在免耕栽培水稻产量构成中,有效穗数变幅较大,施氮区比无肥区高15.38%～48.52%;单株干物重、株高均随氮肥用量的增加而增大。分蘖～孕穗期植株氮素养分干基含量占累计吸氮总量的比例,无肥区为63.91%;不同施氮肥区为65.75%～80.14%。籽粒含氮量占植株的吸氮总量,无肥区为67.42%,不同施氮肥区为60.51%～66.37%,且随氮肥用量的递增而降低。稻株吸自化肥氮量占植株总氮量的比例,不同施氮肥区为10.81%～32.49%。无肥区平均产量可达施氮肥区平均产量的74.62%～84.35%。得出氮肥用量(kg/ha)的一元二次回归方程为 Y=5 346.75+18.588 24x—0.047 5x~2,应用此式计算肥料效应函数,得出碳铵用量984.00kg/ha 为水稻最佳经济施肥量。等氮量不同施肥技术的化肥生产力,经新复极差测验表明,三次追肥法、一基二追法、四次追肥法之间产量差异不显著,但与一次基肥法的差异达到极显著水平。 文摘来源 According to the results of micro field fertilizer test of winter wheat under greenhouse in Heyang county on Weibei Rainfed Highland, the yield response、fertilizer use efficiency and soil NO - 3-Nsupply of winter wheat during growing periods were analyzed. The analysical results indicated three fertilizations with a depth of 15 cm under low, common and high annual precipitations were conducted in mid July, mid August and mid September, respectively. Only one fertilizer supply at presowing stage could mee... 根据渭北旱塬合阳旱棚冬小麦微区试验结果，分析了不同降水年型下不同施肥技术的冬小麦增产效应、肥料利用率和冬小麦生育期土壤供氮状况（以ＮＯ－３－Ｎ含量为指标）。结果表明歉水年型下施肥技术为７月中旬一次深施，平水年型下施肥技术为８月中旬一次深施，丰水年型下施肥技术为９月中旬一次深施，施肥深度均为１５ｃｍ。同时播前播时一次施肥可满足冬小麦强度营养期的需要，而分次施肥则难以满足。 文摘来源 Different fertilizer application techniques were conducted in Longyan to determine methods of balancing fertilization in flue-cured tobacco.The result showed that the6:3:1ratio for row replacement ,hole fertilizer and top dressing was reasonable for flue-cured tobacco.With top dressing in15to20days after trans-planting,the yield and quality of flue-cured tobacco is improved,and the nicotine content in the leaf could be controled in suitable range. 为了确定福建省龙岩烟区平衡施肥方法,进行了不同施肥技术试验。结果表明:龙岩烟区合理的基追肥比例为条沟基肥占60%,穴肥占10%,追肥占30%,追肥采用外注式施肥法,并在移栽后15～20d内结束追肥,烟叶产质量较好,并且能使上部叶烟碱控制在适宜的范围内。 文摘来源 << 更多相关文摘
