不同育苗方式对寒地水稻秧苗素质及产量的影响

为明确日本钵式盘、钵体毯式育苗盘和常规软盘在寒地水稻生产中的作用，研究以空育131、垦稻10和垦稻12为材料，探讨了日本钵式盘、钵体毯式育苗盘和常规软盘的对寒地水稻秧苗素质和产量的影响。结果表明，3种育苗方式的秧苗素质以日本钵式盘最优、钵体毯式育苗盘次之、常规软盘最差，产量也呈现相同趋势。单位面积穗数和穗粒数的提高是日本钵式盘和钵体毯式育苗盘增产的主要原因。综合考虑产量和经济效益，钵体毯式育苗是目前最优的育苗方式。

Influence of Different Raising Seeding Methods on Quality and Yield of Rice Seeding in Cold Region

To clarify Japan seeding,pot-mat seeding and common seeding in the production of rice in cold region,Kongyu 131、Kendao 10 and Kendao 12 were used as material to study the influence of three methods on quality and yield of rice seeding in cold region.The results indicated that the seeding quality of compartment tray of Japan was the best,pot-mat seeding took second place and common seeding with plastic tray was the worst.There was the same trend in yield.The improvement of spike number per unit and grain number per spike was the main reason to increase production by compartment tray of Japan seeding and pot-mat seeding.Considering yield and economic benefit,pot-mat seeding of Japan was the best method at present.
