| 摘 要： | 以吉林省中部地区的水稻土为试验土壤,研究了锌对晚熟粳稻品种“农大3号”生长发育的影响。试验结果表明,与对照相比施锌水平在300mg／kg以下时,水稻株高增加2．4～6．9cm,单株分蘖数增加1．7～9．7个,叶片数增加17．6～48．3片,最多叶片数出现的时间提前约5d;施锌水平大于500mg／kg时,水稻株高降低11．2～13．4cm,分蘖数减少4．6个,叶片数减少17．6～48．3片,最多叶片数出现的时间晚约10d,产量降低4．91％～43．40％,而且穗分化推迟,使水稻的生育期延长约5d。

| Abstract: | A pot experiment using paddy soil in the middle area of Jilin province was conducted to investigate the effects of zinc on the late mature japonica rice " Nongda 3". The result showed that when the concentration was under 300 mg/kg, zinc application was favorable to the growth of rice. Rice plant height increased by 2.4 - 6.9 cm, the number of leaves and tillers increased by 1.7 - 9.7 and 17.6 -48.3 respectively, and the mature period was 5 days in advance. When the rate was above 500 mg/kg, plant height decreased by 11.2-13.4 cm, with leave number 17.6 - 48.3 and the number of tillers 4 -6 inhibited. The appearance period of the most leaved and the differentiation of rice spike were delayed for 10 days and 5 days, respectively. Rice yield decreased by 4.91 % - 43.40% in high concentrations. |
