【摘要】

：

针对传统种植方式下大水漫灌所造成的水资源浪费现象,结合小麦垄作栽培技术,本试验采用了固定道耕作结合垄作沟灌,并采取地膜覆盖和秸秆覆盖的方法,改传统耕作的大水漫灌为小水沟内侧渗灌,设置垄沟比例为2.23:1,研究了固定道耕作结合垄作沟灌对河西走廊春小麦水分利用的影响。试验结果表明: 1. 固定道耕作灌水沟由于压实的影响,在0～20cm 土壤坚实度明显高于传统耕作的,在15cm 左右,固定道耕作各处理

木薯块根基因表达谱分析

木薯是世界六亿人赖于生存的主要食物来源，木薯制取燃料乙醇，既有广阔的市场前景，又是解决我国能源安全的一条重要途径。本文利用华南124木薯，块根膨大期的块根总RNA构建了cDNA文库，制备了125张cDNA微阵列，利用表达序列标签、cDNA微阵列杂交，分析了木薯块根基因表达的情况。文库中得到了2878条序列，对2878个基因进行基本的分析、序列的比对、功能注释、分析了表达基因的丰度、基因注释
