福建双季晚稻机械化育插秧中的问题与对策

目前双季晚稻应用机械化育插秧技术过程中常发生的主要问题有:选用的品种(组合)生育期偏长,秧苗超秧龄严重;出苗不齐,成苗率低;秧苗徒长,苗高超标。通过选择生育期适当的品种(组合),出苗期采用日灌夜排的水分管理方法,适当减少秧田用肥量并施用多效唑控制苗高可以解决这些问题。双季晚稻大面积生产上推广应用机械化育插秧技术有利于增产增收,节本增效。

Major Problems and Measures of the Second Season Rice Mechanized Seedling Cultivate and Transplant in Fujian Province

At present, the major problems of second-season rice mechanized seedling cultivate and transplant is: The growth period of species which has been used was too long and the age of seedling exceeds the right moment. The out seedling was not tidy and the rate of out seedling was low. The high of seedling was over the proper degree. To select the species which have the proper growing period, irrigate at day and drain during night after sowing, reduce the use of fertilizer quantity, using Paclobutrazol to control the high of seedling can resolve above problems. Expansion of the technique of mechanized rice seedling transplant will be helpful to reduce the cost and increase output and income.
