以新香优80、R80、TANGARA和IAPAR9为材料,进行水旱种比较试验,并以TANGARA为材料,喷洒多效唑、云大120、黄腐酸3种植物生长调节剂,对不同时期的陆稻进行化学调控,初步研究水、旱种及化学调控对稻米营养品质的影响.结果表明:各品种水种的米质优于旱种,以IAPAR9品质最优,R80其次；旱种下,TANGARA品质最优,R80其次.喷洒化学药剂能有效地改善稻米的营养品质,提高粗蛋白质含量,与对照相比,黄腐酸处理的粗蛋白质含量增加10.7％,多效唑处理增加7.5％,云大120处理增加5.5％.3种植物生长调节剂有利于提高水稻整精米率,降低垩白率.

In order to preliminarily study the effects of cultivation in paddy-field or upland and different chemical regulators on nutrient quality of rice, the growth characters of Xinxiangyou80, R80, TANGARA and IAPAR9 which cultivated in paddy-field or upland were compared respectively. Meanwhile, MET, BR-120 and BFA were sprayed to different growth periods of TANGARA, the tested variety, to conduct chemical regulating experiment. The results showed that the rice quality of each variety cultivated in paddy-field was superior to that cultivated in upland, in which, the IAPAR9 had the best rice quality...
