摘要
为了分析垄作栽培对西藏春小麦分蘖、生育期等指标的影响变化规律,分别在达孜县章多乡和自治区农科所试验地以春小麦"山春1号"和"藏春951"为材料,开展垄作栽培技术示范研究,结果:垄作栽培改变了春小麦的生理生态条件,促进春小麦叶片功能期的延长,增加了垄作"山春1号"的生育时期;垄作栽培促进了春小麦的总分蘖和有效分蘖数的增长,"藏春95"垄作与平作之间有效分蘖达到了极显著性差异,不同栽培方式的两个春小麦品种的总分蘖间没有达到显著性差异;垄作栽培增加了春小麦次生根数量和长度,不同栽培方式"藏春951"的根数之间达到显著水平;垄作栽培有效改善了小麦穗部性状,不同栽培方式的"藏春951"小穗数之间t值达到6.48,Pr>|t|=0.0002<0.01,达到极显著性差异。在春小麦生长发育中垄作栽培方式对提高春小麦分蘖力、改善其穗部性状、增加次生根数量等都具有明显的正效应。
To analysis the influence of ridge cultivation on Tibetan spring wheat such as tiller and birth period,respectively in chapter Dazi county and experimental field of RIOASOT test to spring wheat 'Shanchun no.1' and ' Zangchun no.951' as material.The results points out;Ridge cultivation change spring wheat physiological ecological conditions,promote spring wheat leaves function period extended,increase Ridge ' Shanchun no.1' Birth period;Ridgecultivation promote spring wheat total tiller and effective tiller numberof growth, ' Zangchun no.951' Ridge ang flatten culture productive tiller reached very an explicit sexual differences,Different Cultivation way two a spring wheat variety total tiller between no reached an exlicit sexual differences;Ridge cultivation increase spring wheat root the number of and length.Different Cultivation way 'Zangchun no.951 ' root number of reached an explicit level;Ridge Cultivation effective improve small spike the Dpartment of characters,different cultivation way ' Zangchun no.951' Small Spike number of T value reached 6.48,Pr > |t| =0.0002 < 0.01,reached very an explicit sexual differences.On spring wheat growth and development of bed- planting in spring wheat tillering ability and improving ways to improve their ear characteristics,such as increasing the number of Secondary roots have a significant positive effect.
