太安大队地处祖国西南、滇西北高原的高寒山区,海拔2,800—2,950公尺。年平均气温10℃左右,最低温度-7 ℃,霜期160—180天。地形复杂,水源奇缺。作物多为杂粮,无水灌溉,基本上是一年一熟。马铃薯占全年粮食总产量的50%以上。我所为探索在山区进行间作套种,提高复种指数,增加单位面积产量的路子,与太安大队科技组相结合,在太安一队作了3.57亩地的小麦和马铃薯套种试验。平均亩产914.1斤(小麦亩产338.7斤、实生薯无性一代折粮亩产549.1斤、实生苗结薯折粮亩产26.3
Tai’an Brigade is located in the alpine mountainous area southwest of the motherland, northwest Yunnan Plateau, elevation 2,800-2,950 meters. The annual average temperature of about 10 ℃, the lowest temperature of -7 ℃, frost-days 160-180 days. Terrain complex, water scarce. Crops mostly grains, anhydrous irrigation, basically a year cooked. The potato accounts for more than 50% of the total grain output in the year. In order to explore inter-cropping intercropping in the mountainous areas, increase the multiple cropping index and increase yield per unit area, I conducted a wheat-potato intercropping experiment with 3.57 mu of land in Taian First Team in combination with the Tai’an BST Technology Group. Average yield of 914.1 kg per mu (338.7 kg of wheat per mu, a generation of real potato asexual yield of 549.1 kg per mu, potato seed yield per mu 26.3
