摘要
为了探究适宜青海省湟中县种植的青稞品种以及播种和施肥方式,选取5个青稞品种(北青8号、北青9号、昆仑14号、昆仑17号及肚里黄)进行品种比较试验,根据苗产量、叶绿素、矿质元素及活性酶含量筛选出优良青稞品种,并针对北青9号,设不同播种(行距和播种量)和施肥(种类和施肥量)方式等多个处理进行丰产栽培和施肥试验,研究不同播种及施肥方式对其矿质元素、叶绿素、超氧化物歧化酶(SOD)、细胞色素氧化酶含量的影响。结果表明,昆仑17号和北青9号矿质元素含量较高,其中昆仑17号的苗产量最高,北青9号的叶绿素含量及细胞色素氧化酶含量最高;随着播种量增多、行距变大,北青9号的矿质元素、SOD、细胞色素氧化酶含量极显著提高,增加N+P肥和N肥施用量,叶绿素和SOD含量极显著升高,增施P肥细胞色素氧化酶含量极显著升高;青稞中大部分矿质元素之间的相关性达到了极显著水平。
In order to explore the highland barley varieties suitable for planting in Huangzhong county,Qinghai province and the optimal methods of sowing and fertilization,five highland barley varieties(Beiqing 8,Beiqing9,Kunlun 14,Kunlun 17 and Dulihuang)were selected for variety comparison test.According to the differencesof seedling yield,chlorophyll,mineral elements and active enzyme contents,excellent highland barley varietieswere selected,and different sowing(row spacing and sowing amount)and fertilization(type and fertilizationamount)methods were set for Beiqing 9,the effects of different sowing and fertilization methods on the contentsof mineral elements,chlorophyll,superoxide dismutase(SOD)and cytochrome oxidase were studied.The resultsshowed that the contents of mineral elements in Kunlun 17 and Beiqing 9 were higher,among which the seedlingyield of Kunlun 17 was the highest,and the contents of chlorophyll and cytochrome oxidase of Beiqing 9werethe highest.The contents of mineral elements,SOD and cytochrome oxidase in Beiqing 9 increased significantlywith increasing of seeding amount and row spacing,the contents of chlorophyll and SOD increased significantlywith the increasing of N+P and N fertilizers,and the contents of cytochrome oxidase increased significantlywiththe increasing of P fertilizer;The correlation between most mineral elements in highland barley reached a verysignificant level.
