摘要
用 1 5 %多福悬浮种衣剂对水稻种子进行包衣处理 ,研究发现 :在秧苗期 ,该种衣剂能提高秧苗茎蘖数、根长、鲜重和叶绿素含量 ,对苗高、叶龄和根数的影响不明显。对水稻经济性状及产量调查发现 ,种衣剂能显著提高每窝穗数、有效穗、穗平均着粒数、理论产量和实际产量 ,对株高、穗长、穗平均实粒数。
Rice seeds were treated with rice coating material. Theresult showde that, in the period of rice seedling, the rice coating material can increase number. of seedling tillers and stem, promote root length, enhance fresh seedling weigh, level of chlorophyll, while the effect on seedling height, leaf age, number. of root and root vigor was very little. on the whole , the seed coating material can improve seedling quality. The investigation of rice economy characteristic and yield showed that,the material can enhance panicle per plant, effective panicle, panicle length and spikelets per panicle, and also canincrease the yield of rice. But the effect on plant height ,panicle length, realspikelets per panicle, 1000 grain weight and seed setting rate were very little.
