稻麦亩产吨粮试验和示范推广在昆明北郊龙泉公社中坝大队雨树村生产队进行。这里海拔1920—2000公尺。水田414亩中,红泥田224亩,冷浸田30亩,沙滩田50亩,其余为泥田和红泥田。按土壤肥力来分:高产田82亩、中产田252亩、低产田80亩。约有一半面积靠抽水灌溉。因靠近松花坝水库,风大、水冷、土温低,小麦成熟迟,水稻栽插晚,后期易受低温为害,稻麦两季产量低而不稳,原来两熟亩产800—1000斤。
Rice and wheat production of tons of grain test and demonstration of grain in the northern suburbs of Kunming Longquan commune in the dam team Yushu village production team. Here 1920-2000 meters above sea level. 414 acres of paddy fields, 224 acres of red muddy fields, cold paddy fields of 30 acres, 50 acres of beach fields, the rest for the mud fields and red mud fields. According to soil fertility to points: 82 acres of high yield fields, 252 acres of middle-yielding fields, low-yielding fields 80 acres. About half of the area is irrigated by pumping. Due to close to Songhuaba Reservoir, the wind, water, soil temperature is low, late maturity of wheat, late rice planting later vulnerable to low temperature damage, low yield and instability of rice and wheat in the two seasons, the original double cropping 800-1000 pounds.
