3、劣、产量的高低直接影响到垦区及全省的水稻现状。本研究 于2014年开展，以建三江七星农场为研究区域，探讨龙庆稻3号与三江6号不一致养分 管理下产量品质的差异及机理。试验使用随机区组设计，进行化肥+生物有机肥、减氮+生 物有机肥、减氮+生物有机肥+硅、减氮+生物有机肥+锌的效果研究。要紧研究结果如下：1 .两品种高产栽培模式为常规施肥+归复记生物有机肥300kghm2,能够显著提高分薨 数、叶面积指数、地上部生物量与吸氮量、公顷穗数与穗粒数，最终使两品种产量分别提 高15.0%与9.2%o增施归复记生物有机肥300kghm2+减氮20%处理两水稻品种的分蕖数、 叶面积指数、地上部生物量与吸氮量均

4、与常规施肥无明显差异，产量与产量构成因子也均 无明显差异，而水稻株高显著下降、抗病性显著升高、氮素偏生产力显著提高。2 .增施生物有机肥下稻米的品质与常规施肥处理并没有显著差异。减少氮肥20%有提 高水稻品质的趋势，两品种水稻优质栽培模式为减氮20%+增施归复记生物有机肥 300kghm2+基施锌肥5kghm2处理与减氮20%+增施归复记生物有机肥BOOkg/hn?+喷施硅 月巴 1.2Lhm2o3 .基施锌肥能够显著地提高茎薨数、提高叶面积指数、地上部生物量及吸氮量、提高 了水稻褐变穗的抗病性，最终增加了公顷穗数，龙庆稻3号与三江6号分别增产7.0%与 3.4%；增施锌肥后稻米的精米率与整精

5、米率均显著提高，降低了垩白度，不仅提高了直链 淀粉含量，也降低了蛋白质含量，大大改善了稻米的品质。4 .叶面喷施有机硅肥能够显著地降低两品种水稻株高、褐变穗的发病率与病情指数。 叶面喷施有机硅处理水稻的叶面积指数、地上部生物量与吸氮量与公顷穗数有增高趋势， 但差异不显著，最终也没有显著增产。喷施硅肥后龙庆稻3号提高了整精米率、降低了垩 白率，三江6号也表现类似趋势。直链淀粉分别提高了 3.9%与6.9%,蛋白质分别降低了 2.6% 5.4%o关键词：七星农场；生物有机肥；硅；锌；水稻品质AbstractHigh yield and good quality of rice in cold ar

6、ea are not only influenced by genetic factors, but also by the environment and the cultivation technique during the rice growth. So it is the result of genetic and environmental interactions. The area of rice growth in Jiansanjiang is more than 10 million mu, which is accounting for 42.6% of farming

7、 areas of Heilongjiang Province and 16.7% of rice growing area in Heilongjiang Province. The yield and quality of rice in Jiansanjiang are very important for rice growing in Heilongjiang Province. Therefore, the study for effects of different nutrient management on rice yield and quality in Qixing f

8、arm is needed. In this study, we conducted field plot experiments in the research and development center of Qixing farm in 2014 and Longqingdao 3 and Sanjiang 6 used as the study rice varieties. The 5 different nutrient management treatments were set up. The results were as follows:Two varieties of

9、high yield cultivation model was conventional fertilization and increasing biological organic fertilizer treatment. Two varieties of rice in increased biological organic fertilizer treatment can significantly improve the tillering number, leaf area index, aboveground biomass and nitrogen uptake, and

10、 the panicle number per hectare and grain number per spike of botnrice varieties. Eventually yield and partial factor productivity for nitrogen (PFP-N) were significantly increased. Moreover, Increase biological organic fertilizer and decreased N treatment was no difference with conventional fertili

12、gen 20% had a tendency to improve rice quality of both varieties of rice, cultivation mode of high quality to reduce nitrogen 20% + increased 300 kghm2 adapt to Guifurji biological organic fertilizer rates + base zinc fertilizer 5 kghm2 processing and reduce nitrogen 20% + increased 300 kghm2 adapt

13、to remember biological organic fertilizer rates + spraying silicon fertilizer 1.2 Lhm2.Increasing zinc (Zn) fertilizer treatment could significantly increase the stem tillering number, leaf area index, aboveground biomass and nitrogen uptake. Eventually the panicle number per hectare was finally sig

14、nificantly higher. Rice yield for both varieties had increased trend, but no significantly. In addition, increasing Zn fertilizer treatment can significantly improve the quality of rice for two varieties.Spraying on the leaf of organic silicon fertilizer can significantly reduce the two varieties of

15、 rice plant height, Browning incidence and disease index. Rice leaf area index, aboveground biomass and nitrogen uptake and ha panicles, spraying on the leaf organic silicon processing relative to not spraying process has increased trend, but the difference was not significant, eventually did not in

And spraying silicon fertilizer can significantly improve the quality of paddy rice, and after spraying silicon fertilizer Longqingdao 3 improves the whole polished rice rate increase and reduced the rate of chalk white, Sanjiang 6 shows a similar trend. In addition, two kinds of nutritional quality also increased significantly. Amylose increased by 3.9% and 6.9% respect
