| 摘 要： | 目的]就不同移栽方式对水稻产量及其效益的影响进行分析。方法]以丹粳253、沈农6014为试材,采用乳苗抛栽、抛秧、插秧、大垄双行水和水直播(对照)5种移栽方式,比较研究了不同移栽方式对水稻群体的产量性状及其效益的影响。结果]不同纬度地区不同栽培方式产量差异极显著。在沈阳地区,不同栽培方式水稻产量排序依次为插秧>抛秧>乳苗>大垄双行>水直播;在丹东地区,不同栽培方式水稻产量排序依次为大垄双行>抛秧>乳苗>插秧>水直播。乳苗抛栽的产量在不同纬度地区差异很大。丹东地区的乳苗抛栽水稻的产量较沈阳的高3 486.45 kg/hm2。乳苗抛栽平均可比插秧栽培节约1 018.5元/hm2,比抛秧栽培节约726.0元/hm2。结论]不同栽培方式之间产量差异达到了极显著水平,产量与每公顷穗数、每穗颖花数、成粒率、千粒重的正相关达极显著水平。 |

| Abstract: | Objective] The purpose of the study was to analyze the influences of different transplanting patterns on rice yield and benefit.Method] With Dangeng 253 and Shennong 6014 as tested materials,5 transplanting patterns of nursling-seedling-scattering,seedling throwing,transplanting,big ridge double line and water direct seeding(CK) were adopted to compare the influences of different transplanting patterns on yield characters and benefit of rice communities.Result] The yield differences among different cultivation patterns in the areas at different latitudes were extremely significant.In Shenyang area,the order of rice yield by different cultivation patterns was transplanting>seedling throwing>nursling-seedling>big ridge double line>water direct seedling.In Dandong district,the ordination of rice yield with different cultivation patterns was big ridge double line>seedling throwing>nursling-seedling>transplanting>water direct seedling.There was great difference in the rice yield by nursling-seedling-scattering in the areas at different latitudes.The yield per hm2 of rice by nursling-seedling-scattering in Dandong was 3 486.45 kg higher than that in Shenyang area.Compared with transplanting and seedling throwing cultivation,the nursling-seedling-scattering averagely saved 1 018.5 and 726 yuan per hm2 respectively.Conclusion] The yield differences among different cultivation patterns reached extremely significant level.The positive correlation between the yield and spike numbers per hm2,spikelet numbers per panicle,granulating rate and 1 000-seed weight reached extremely significant level. |
