摘  要：
通过田间试验评价了几种水稻专用配方肥及其配套施肥技术对水稻生长、产量、养分吸收、肥料利用率和经济效益的影响。结果表明,施肥可提高水稻的产量和经济效益,与习惯推荐处理相比,推荐用量试验中,配方肥2(N-P_2O_5-K_2O为22-6-12)、配方肥4(N-P_2O_5-K_2O为20-9-16)分别增产5.9%、4.4%,纯收入、产投比明显高于其他处理,对应配方及施肥技术较为合理。等氮用量试验中,配方肥1(N-P_2O_5-K_2O为20-12-14)和配方肥6(N-P_2O_5-K_2O为20-0-10)在施肥量降低的同时维持了高产,提高了经济效益;配方肥3(N-P_2O_5-K_2O为20-8-15)和配方肥5(N-P_2O_5-K_2O为20-10-12)的施肥量减少,产量及经济效益均有所降低。综合来看,水稻专用配方肥2和配方肥4的配方及推荐施肥技术均较合理,配方肥1应适当减少施肥量,配方肥3和配方肥5可通过增加施肥量或优化配方来提高其肥效,配方肥6建议适当添加磷肥的同时降低钾肥比例。

摘  要：
Field trials were conducted to study the effects of several rice special formula fertilizer and corresponding fertilization technology on rice growth, yield, nutrient uptake, fertilizer use efficiency and economic benefits. The results showed that fertilization could significantly increase the yield of rice and economic benefit. Compared with that of the experience recommended fertilization(ERF) treatment, the yield of rice special fertilizer(RSF) 2(N-P_2O_5-K_2O,22-6-12), 4(N-P_2O_5-K_2O,20-9-16) treatment were increased by 5.9%, 4.4%. Net income and benefit cost ratio were also significantly higher than that of other treatments indicating that the formula and fertilization technology was reasonable. In the equivalent nitrogen fertilizer experiment, the output of RSF 1(N-P_2O_5-K_2O,20-12-14) and 6(N-P_2O_5-K_2O,20-0-10) treatments remained stable and the economic benefit was increased although the amount of fertilization decreased. The yield and economic benefit were decreased for RSF 3(N-P_2O_5-K_2O,20-8-15),5(N-P_2O_5-K_2O,20-10-12) because of the decrease of fertilizer application amount. Overall,formula and recommended fertilization technology of the RSF 2 and 4 were more reasonable. Fertilization amount of RSF 1could be reduced properly. Fertilization amount of RSF 3 and 5 could be increased to improve the effects. For RSF 6, phosphate fertilizer should be increased and potash fertilizer should be reduced at the same time appropriately.
