摘要
采用盆栽和田间试验,研究了氢醌对水田土壤脲酶活性、水稻生长和产量性状的影响,试验结果表明,随氢醌用量增加,对水田土壤脲酶活性抑制率增大,抑制时间增长;尿素配施适量氢醌,能促进水稻生长发育、干物质积累,并提高了稻谷产量;施用氢醌提高了水田土壤供氮能力和植株含氮量。
The effects of hydroquinone on inhibition rate of creaseactivity in paddy soil and rice growth and yield were studied under potand field conditions.Results shows that the inhibition rate of soil ureaseactiyity by hydroquinone was increased as increasing appplication rate,and the necessary duration for the restoration of urease activity wasdecreased as decreasing appplication rate of this or panic compound; applyingproper amount of hydroquinone and urea may promote growth, dry matteraccumulation and increase yield of rice; paddy soil nitrogen supplyingcapacities and the total nitrogen content of rice plant were also increasedby applying hydroquinone.
