为有效改善土壤酸化对水稻安全生产构成的威胁,探讨不同土壤改良剂在水稻上的应用效果,选择武穴市2个镇通过田间试验比较4种不同土壤改良剂在酸化稻田上的应用效果.结果 表明:施用土壤改良剂不仅能不同程度提高酸化稻田的土壤pH,还能显著提高酸化稻田的水稻产量与产值.与基础土壤相比,四望镇和大金镇施用生石灰、有机肥、钙镁磷肥、土壤调理剂的土壤pH分别提高0.31、0.14、0.20、0.32和0.24、0.13、0.22、0.30.通过两镇的水稻产量与产值分析比较,施用土壤调理剂和生石灰处理的产量较高,且均是生石灰处理获得了最大利润和最高产投比,四望镇和大金镇的水稻亩纯利润、产投比分别为50元、1.83和70元、2.17.建议本地区酸化稻田适宜土壤改良剂为生石灰.

To study the effects of nitrogen, phosphorus and potassium on yield and fertilizer use efficiency of double-rice in southeast Hubei,“3414” fertilizer experiment was conducted in Wuxue county, Hubei province. The results showed that when 112.5 kg/hm2 K2O was used for early rice, effect of potassium fertilizer on yield was good and the yield and rate of growth were 5 974 kg/hm2 and 10.9%, respectively. For the second rice, using 247.5 kg/hm2 N was good and the yield and the rate of growth were 8 627 kg/hm2, 29.3%. The fertilizer use efficiency showed that for the early season rice, applying 165.0 kg/hm2 N led to higher fertilizer contribution rate and agronomic efficiency than other levels of N use, which were 13.8% and 4.9 kg/kg, respectively. Using 30.0 kg/hm2 P2O5 detained higher fertilizer contribution rate and agronomic efficiency than other levels of P2O5 use and the value were 5.9% and 11.5 kg/kg, respectively. Applying K2O of 112.5 kg/hm2 and 37.5 kg/hm2 could obtain higher fertilizer contribution rate and agronomic efficiency with 9.9% and 7.9 kg/kg. For the second rice, apply-ing 247.5 kg/hm2 N led to high fertilizer contribution rate of 22.7% while applying 165.0.0 kg/hm2 obtained agronomic effi-ciency of 9.9 kg/kg. Using 60.0 kg/hm2 P2O5 obtained high fertilizer contribution rate of 7.1% and the agronomic efficiency of 11.7 kg/kg better than that of using 30.0 kg/hm2 P2O5. Applying 75.0 kg/hm2 K2O obtained fertilizer contribution rate and a-gronomic efficiency of 9.9% and 11.0 kg/kg higher than other levels of K2O.

试验以双季稻为材料,研究了不同施肥处理对鄂东南双季水稻产量及养分吸收利用的影响.结果表明,与不施肥处理(CK)相比,习惯施肥、测土施肥和控释氮肥处理的双季稻周年产量分别增产18.0％、20.9％和12.8％.施肥处理双季稻的株高、有效穗数和每穗实粒数也有明显增加,而千粒重和结实率无显著变化.与CK相比,各施肥处理明显提高了双季稻各器官对N、P、K的吸收累积量.不同养分的吸收累积量在双季稻不同器官中的分布存在差异,N和P表现为子粒大于秸秆,K则表现为秸秆大于子粒.施肥降低了N、P、K在子粒中的分配比例.双季稻的肥料利用率结果显示,测土施肥处理肥料偏生产力和农学利用率均最高;与习惯施肥处理和拉释氮肥处理相比,早稻肥料偏生产力和农学利用率分别提高了28.7％、8.6％和62.5％、48.6％,晚稻分别提高了19.7％、6.4％和17.6％、90.5％.

近年来，随着桃市场行情的变化，晚熟桃在鄂东地区相对较为俏销，市场价格较高，我地果农先后发展了一批晚熟桃园，目前已陆续投产，为推进我地农业产业结构调整，探索水果生产发展新途径，在生产过程中，探索了一套晚熟桃在鄂东地区的栽培管理技术。

The effects of different planting methods,cultivation methods,groove width configurations on rapeseed yield and the output and economic benefits were studied with Zhongshuang No.10 as material.The results showed that the yield was impacted very significantly under different cultivation methods,groove width configurations and tillage methods.The net profit under no-tillage transplanting was the highest,under no-tillage and direct casting,but net profit under tillage transplanting was the lowest;the profit margin under the no-tillage and direct casting was the highest,the second one was under the no-tillage transplanting,the lowest one was under tillage transplanting.
