沙漠多晶硅光伏连栋温室适宜栽培的瓜类作物筛选研究

摘要

In polysilicon photovoltaic multispan greenhouse,the south of the bay is opacity polysilicon photovoltaic panel,and the north is PC sunlight panel,which form the zone of sunlight and shadow in the field.Two muskmelon varieties Zaochunmi and Xinhongbao,and three watermelon varieties Ribenlidu,Jinge as well as Lüihu were planted in this greenhouse to research the changes of crop growth,fruit quality and yield in different light conditions.The results showed that the stem diameter and plant height of Zaochunmi had significant differences in the north,central part and south under photovoltaic panel;the chlorophyll content and leaf number were the highest in the north;the fruit soluble sugar content and single fruit weight had no significant differences in different light conditions;the soluble solids and VC content were the biggest in the central.For Xinhongbao,the stem diamneter was the smallest in the south;the plant height and leaf number were the lowest in the north,while the chlorphyll content was the highest;the soluble solids and soluble sugar content had no significant differences in different light conditions;the single fruit weight in the central part was higher than that in the south.There was no significant differences in leaf number of Ribenlidu in different light conditions;the soluble sugar content and single fruit weight were both the highest in the north.For Jinge,the leaf number and VC content had no significant differences in different light conditions.In summary,when planting one single crop,Zaochunmi was the most suitable variety,followed by Lüihu;when planting several crops together,Ribenlidu was suitable to be planted in the north,and Zaochunmi or Lühu in the central and north parts.%本试验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.温室内种植早春蜜、鑫红宝2个甜瓜品种和日本丽都、金哥、绿葫3个西瓜品种,系统研究光伏板北、中、南部下作物生长、品质和产量的变化.结果表明,北、中、南部早春蜜的茎粗和株高差异显著,北部叶绿素和叶片数均最高,北中南部可溶性糖含量和单果重无显著差异,可溶性固形物和VC含量均为中部最高;鑫红宝南部茎粗最低,北部株高叶片数最低,叶绿素最高,北、中、南部可溶性固形物、可溶性糖含量无明显差异,单果重中部高于北部高于南部;北、中、南部日本丽都叶片数无显著差异,可溶性糖、单果重均是北部最高;北、中、南部金哥叶片数、VC含量均无明显差异,综合产量和品质单一种植一种作物时早春蜜最适宜种植,绿葫次之,或北部日本丽都,中南部早春蜜或绿葫.
