采用水稻移栽前10 d秧田期药剂处理,研究了脱落酸.吲哚丁酸和脱落酸对水稻的影响。两年试验结果表明:水稻移栽后15 d,脱落酸.吲哚丁酸33.3、50.0和100.0 mg/kg处理,秧苗分蘖数平均比清水对照增加15.63%、17.52%和15.78%;脱落酸1.0 mg/kg处理分蘖数增加5.38%。水稻移栽后30 d,脱落酸.吲哚丁酸上述3种浓度处理秧苗分蘖数依次增加8.88%、10.63%和9.16%;脱落酸处理增加0.87%。水稻成熟期调查,脱落酸.吲哚丁酸3种浓度和脱落酸处理,有效穗、结实数均比清水对照有所提高。脱落酸.吲哚丁酸33.3、50.0和100.0 mg/kg处理和脱落酸1.0mg/kg处理,水稻实收产量顺次比清水对照增产4.95%、6.03%、9.35%和5.89%。品质测定结果显示:脱落酸.吲哚丁酸3种浓度处理和脱落酸处理,稻米垩百度、蛋白质等质量指标与清水对照相比无明显变化。
The effects of abscisic acid, indole butyric acid and abscisic acid on paddy rice were studied using the rice seedling 10 days before transplanting. The results of two years showed that on the 15th day after transplanting, abscisic acid, indole butyric acid, 33.3, 50.0 and 100.0 mg / kg treatments increased the average number of tillers of seedlings by 15.63%, 17.52% and 15.78% mg / kg treatment tiller number increased 5.38%. After 30 days of transplanting, the number of tillering of seedlings treated with indole butyric acid increased by 8.88%, 10.63% and 9.16%, respectively, and that of abscisic acid increased by 0.87%. Investigation of rice maturity, abscisic acid, indole butyric acid concentration and abscisic acid treatment, effective panicles, solid number were higher than the control of water increased. Abscisic acid, indole butyric acid 33.3, 50.0 and 100.0 mg / kg treatment and abscisic acid 1.0 mg / kg treatment, the yield of rice in succession increased 4.95%, 6.03%, 9.35% and 5.89% The results of quality measurement showed that abscisic acid, indole butyric acid and abscisic acid treatment did not change the quality indexes of rice chalk and protein.
