钵形毯状秧苗和常规毯状秧苗机插对水稻产量结构及其产量的影响

[目的]探讨钵形毯状秧盘育秧机插技术，在淮北黏土地区的适应性，为在该地区大规模推广应用该农机具提供理论依据．【方法]采用常规毯状秧盘与钵形毯状秧盘机插对比试验的方法，于2013年在东辛分公司选择试验面积10hm。，当年统计两种育秧盘的秧苗素质、栽插均匀度、茎蘖和叶龄状况、产量及其构成因素状况，进行成本及经济效益分析。[结果]钵形毯状秧盘育的秧苗其根量、主茎高、茎基宽、白根数、百株干重和质量高比均优于常规毯状秧盘育的苗，当年钵形毯状秧盘育秧机插技术平均产量达11640kg/hm2，比常规毯状秧盘育秧机插技术增产4．6％。[结论]试验证明水稻钵形毯状秧盘育秧机插技术是一项节本、增效的水稻机械种植技术，适合在淮北黏土地区推广应用。

Effects of Machine Transplanting of Bowl and Blanket Shaped Seedling and General Blanket Seedling on Rice Yield Component and Yield

[ Objective] To discuss the adaptability of bowl and blanket shaped seedling transplanting technology in clay area of Huaibei, which will provide theoretical basis for large-scale application of the machine. [ Method] Selecting 10 hm2 area to conduct contrast experiments in 2013, the seedling quality, transplanting eveness, tiller and leaf age, yield and components were investigated to conduct cost and economic benefit analysis. [ Result] The root quantity, main stern height, stem width, white root number and dry weight 100 plants, ratio of quality and height of bowl and blanket shaped seedlings are all superior than that of general blanket seedlings. The average yield of the former one is 11 640 kg/hm2, increased by 4.6% than general blanket shaped seedlings. [ Conclusion] The transplanting technology of bowl and blanket shaped seedling is a cost-saving and efficient-increasing technology, which is appropriate for extension and application in clay area of Huaibei.
