沙漠多晶硅光伏连栋温室茄果类作物适宜栽培的位置筛选

Screening the Solanaceous Vegetable Crops Suitable for Cultivation Position in Desert Polycrystalline Silicon Photovoltaic Greenhouse

为促进多晶硅光伏连栋温室的茄果类的高效种植,针对多晶硅光伏连栋温室,开间南部为不透光的多晶硅光伏板,北部为PC阳光板,田间生成阴阳带,种植主栽欧盾、千禧番茄品种,航椒和黄金塔辣椒品种,系统研究了北中南部光伏板下茄果类长势、品质和产量的变化。结果表明:欧盾北、中、南部株高与叶绿素无显著差异,北部可溶性固形物、可溶性糖、硝酸盐含量以及单果重均显著低于中部或南部,中部和南部单果重差异不显著;千禧北、中、南部茎粗与叶片数差异不显著,南部株高最高,可溶性糖含量最高、硝酸盐最低,北、中、南部VC与单果重均无显著差异;航椒中、南部株高、叶片数均为无显著差异,北部叶绿素含量最高,北部可溶性糖和单果重最低,中部可溶性糖最高,南部单果重最高,VC最低;黄金塔中部植株长势最优,南部次之,北部最弱,南部可溶性固形物、可溶性糖、VC、单果重均最高,北部果实品质与产量均最低;总之,从产量考虑,欧盾适宜中、南部,千禧北、中、南部,航椒南部,黄金塔南部种植,从品质考虑欧盾、航椒适宜中部,千禧、黄金塔适宜南部种植。

In order to promote the efficient cultivation of solanaceous vegetable crops in polysilicon photovoltaie greenhouse, according to the zone of sunlight and shadow of greenhouse of polysilicon photovoltaic greenhouse, opacity polysilicon PV panels was in south, and the PC board was in north. Two tomato varieties（Oudun and Qianxi）and two pepper varieties（ Hangjiao and Huangjinta） were planted in greenhouse. The change of the crop growth, fruit quality and yield in different light condition was studied. The results showed that stems and plant height of Oudun have no significant difference,and whose northern plants soluble solids, soluble sugar and nitrate content were lower in central and south areas, central and southern fruit weight difference were not signif- icant. Qianxi stern diameter and leaf number had no significant difference in all parts, plant height was the highest in southern,soluble sugar was the lowest in southern part, nitrate,VC and single fruit weight had no significant difference in north,central and southern parts. The Plant height and leaf number of Hangjiao were no significant differences between central and south parts, chlorophyll content was the highest in north parts, but soluble sugar and single fruit weight were the minimum, soluble sugar was the highest in central, single fruit weight was the highest in southern,and VC was minimum in south. Huangjinta plant was optimal in cen- tral and followed south, the weakest was in the north, and soluble solids, soluble sugar, VC and single fruit weight were all the highest in the south, fruit quality and yield were the lowest in north. In brief, considered production,Oudun was suitable planted in central and south,Qianxi was suitable planted in all parts, Hangjiao was suitable planted in south, and Huangjinta was suitable planted in south. Considered aruit quality, Oudun and Hangjiao were suitable planted in central, Qianxi and Huangjinta were suitable planted in the south.
