中文摘要:

为给生态光伏区小麦高产栽培提供参考，以黄淮麦区南片主栽品种连麦2号、连麦6号、连麦7号、连麦8号、淮麦33、淮麦39、徐麦30、徐麦33、徐麦35、保麦2号、保麦5号和保麦6号为试验材料，在连云港生态光伏区以自然环境为对照（CK），设置光伏板下小区全遮荫、半遮荫和未遮荫三个处理（分别用Z1、Z2和Z3表示），研究光伏板遮荫对小麦生长发育及产量的影响。结果表明，12个品种中，连麦6号、连麦7号、连麦8号和徐麦33籽粒产量均比较高，其中以连麦7号产量最高。与CK相比，光伏板下12个小麦品种的籽粒产量均降低，且产量表现为CK＞Z3＞Z2＞Z1。在Z3条件下，连麦7号、连麦8号、徐麦30和徐麦33干物质积累量较高。不同品种株高对遮荫的反应不一，如在三个遮荫处理下徐麦35的株高在三个遮荫处理下均较CK降低，且以Z2处理降幅最大；徐麦33的株高在三个遮荫处理下均显著增加；连麦2号、连麦6号和连麦8号的株高在三个遮荫处理下有增有减。在花后35 d，连麦2号、连麦6号、连麦7号、连麦8号和徐麦33旗叶SPAD值能够保持较高水平。不同遮荫处理下小麦生育后期旗叶SPAD值表现为CK＞Z3＞Z2＞Z1，其中Z3和CK处理间无明显差异。综合分析生态光伏区小麦产量、生长发育和旗叶光合特性，12个小麦品种在Z3处理下达到最优。12个品种中以连麦7号、连麦8号和徐麦33产量较高，更能适应弱光条件。

英文摘要:

In order to study the effect of growth and grain yield of wheat on different shading of photovoltaic panels,the experiment was conducted through setting different shading treatments in ecological photovoltaic region of Lianyungang. The main cultivars,including Lianmai 2,Lianmai 6,Lianmai 7,Lianmai 8,Huaimai 33,Huaimai 39,Xumai 30,Xumai 33,Xumai 35,Baomai 2,Baomai 5 and Baomai 6 of South huang-hai region were used as materials. The main results indicated that the grain yield of Lianmai 6,Lianmai 7,Lianmai 8 and Xumai 33 were relatively higher than that of others varieties. Compared with CK,shading treatments could reduce grain yield of twelve wheat varieties,which mainly manifested as CK＞Z3＞Z2＞Z1. The dry matter accumulation of Lianmai 7,Lianmai 8,Xumai 30 and Xumai 33 were relatively higher than that of other varieties under Z3 treatment. The results showed that the different shading treatments had significant effect on plant height of different wheat varieties.Such as the plant height of Xumai 35 under three shading treatments was lower than CK, and the largest decline was Z2.The plant height of Xumai 33 was increasing significantly under three shading treatments, which sometimes increased and sometimes decreased of Lianmai 2, Lianmai 6 and Lianmai 8.In addition,the SPAD value of flag leaves could maintain high level for Lianmai 2,Lianmai 6,Lianmai 7,Lianmai 8 and Xumai 33 at 35d after anthesis stage. The effect of shading treatments on SPAD value of flag leaves was manifested as CK＞Z3＞Z2＞Z1,but there were no significant differences between Z3 and CK among them. The suitable shading treatment with different wheat varieties can achieve the coordination and improvement among grain yield,growth and characteristics of flag leaf photosynthesis. The appropriate shading treatment of twelve wheat varieties was Z3. Comparatively,grain yields of Lianmai 7,Lianmai 8 and Xumai 33 were higher than that of other varieties and could easily adapt the conditions of weak light.
