昆明北郊龙泉公社中坝大队,海拔1950公尺,靠近松花坝水库,风大、水冷、气温低,土壤为中下肥力水平的红泥梯田,靠抽水灌溉,耕作粗放,小麦亩产300—400斤;麦后稻栽插晚、分蘖少、分蘖迟,成穗率低,脚穗多,成熟不一致,后期易受低温为害,空枇率高,产量低而不稳,亩产500—600斤,稻麦两季亩产仅800—1000斤。试验和示范结果我们在中坝大队进行了两年吨粮栽培试验,亩产都达到了两千斤以上;1980年在同样的条件下,扩大示范20亩,也获成功。结果如下表。从表一看出:小麦基本苗从10—19万,有效穗30—40万,产量都能达千斤以上。再 Kunming, the northern suburbs of Longquan commune in the dam group, 1950 meters above sea level, near the Songhua dam reservoir, the wind, water, low temperature, the soil is fertile red mud terrain level, by pumping irrigation, extensive farming, 400 kg; late wheat planting late rice, less tiller, late tillering, low spike rate, foot spike, mature inconsistencies, the late vulnerable to cold damage, empty pod rate, low yield and instability, yield 500-600 Kg, two quarters of rice and wheat per mu only 800-1000 pounds. Tests and Demonstration Results We conducted a two-year trial of grain cultivation in Zhongba Brigade with a yield of more than two kilos per mu. In 1980, under the same conditions, the demonstration of 20 mu of demonstration land was also successful. The results are as follows. Seen from Table 1: The basic wheat seedlings from 10-190,000, the effective panicles 30-40 million, the output can reach over a thousand pounds. again
