【摘要】 以杂交香稻组合培杂软香和常规香稻品种桂香占为材料,采用盆栽试验,研究了施用锌、铁、镧肥对香稻米质和产量的影响。结果表明,氯化锌基施和喷施及氯化镧基施处理均能显著地提高培杂软香和桂香占的整精米率,6个锌、铁、镧肥施用处理均能显著地增加桂香占的整精米率而降低其垩白粒率,氯化铁基施和喷施处理亦能显著地降低培杂软香的垩白度;氯化锌喷施处理能显著地提高培杂软香和桂香占的结实率和产量,氯化镧和氯化铁喷施处理亦能显著提高桂香占的产量。更多还原

【Abstract】 The effects of zinc,iron and lanthanum application on grain quality and yield of aromatic rice were studied in pots by using one aromatic conventional rice cultivar,Guixiangzhan,and one aromatic hybrid rice combination,Peiza Ruanxiang.The results showed that,the treatments of basal application of zinc and lanthanum fertilizers,and that of spraying zinc fertilizer increased significantly the head rice rate of both Peiza Ruanxiang and Guixiangzhan;all of the six treatments of zinc,iron and lanthanum application had a significant increase in head rice rate but a decrease in chalky rice rate;the treatments of basal application and spraying of iron fertilizer reduced significantly the chalkiness of Peiza Ruanxiang; and the treatment of spraying zinc fertilizer increased significantly the seed set and grain yield of Peiza Ruanxiang and Guixiangzhan,the treatments of spraying of lanthanum and iron fertilizers also increased significantly the grain yield of Guixiangzhan.更多还原
