Abstract

The length and span of passive solar greenhouse are important factors that determine greenhousemicroclimate. However, there are no established length and span recommendations for guiding construction of passive solar greenhouse in high altitude regions, especially above 3000 m asl. Majority of the farmers in trans- Himalayan regions have preference for low-cost small size (<10 m length) passive solar greenhouses. We studied two different sized greenhouses and found that a large greenhouse (27.4 m length, 8.2 m width) was better than a small greenhouse (9.8 m length, 5.5 m width) for growing cauliflower and cabbage in winter. The large greenhouse remained 1.5±0.3 to 7.4±2.1 °C warmer during daytime, and 0.6±0.1 to 1.5±0.8 °C warmer at night. All the recorded plant growth parameters were higher in the large greenhouse. The mean marketable weight of cauliflower cv. Shantha was 599±35 g in the large greenhouse as against 537±42 g in the small greenhouse. Similarly, the marketable weight of cabbage cv. Golden Acre in the large greenhouse was significantly higher (619±53 g) than the small greenhouse (523±121 g). Therefore, large passive solar greenhouses are recommended for farmers in high altitude trans-Himalayan Ladakh regions.
被动式日光温室规模决定印度拉达克山区冬季花椰菜和卷心菜的生长和产量
被动式日光温室的长度和跨度是决定温室半气候的重要因素。然而,对于高海拔地区,特别是海拔3000 m以上地区的被动式日光温室建设,目前尚无确定的长度和跨度的指导建议。跨喜马拉雅地区的大多数农民偏爱低成本的小型(10米长)被动式太阳能温室。我们研究了两个不同大小的温室,发现一个大温室(27.4米长,8.2米宽)比一个小温室(9.8米长,5.5米宽)更适合在冬季种植花椰菜和卷心菜。大型温室白天升温1.5±0.3 ~ 7.4±2.1℃,夜间升温0.6±0.1 ~ 1.5±0.8℃。所有记录的植物生长参数在大棚中均较高。菜花平均可售重量cv。大温室的香达为599±35 g,小温室为537±42 g。同样地,白菜的销售重量cv。大型温室的黄金面积(619±53 g)显著高于小型温室(523±121 g)。因此,建议跨喜马拉雅拉达克高海拔地区的农民使用大型被动式日光温室。
