淮北气候温和,适宜种植大豆,但在大豆生育期中,有时会遇到短期干旱,在个别年份还会遇到高温枯旱,严重影响大豆的高产稳产。为了从品种本身寻求抗旱途径,我们培育出了抗旱性较强的大豆品种——蒙城2号和蒙城1012。蒙城2号蒙城2号是我场1966年从宿县647大豆品种田中选择变异单株培育而成的。目前在蒙城、濉溪等县推广约5万亩,一般亩产300—400斤。去年我区大旱,长期高温38℃以上,许多大豆品种产量锐减,有的品种甚至颗粒无收,而该品种亩产206斤,比济南1号(亩产20斤)增产103.2%。特征特性:株高55厘米左右,分枝4—5个。全株密着黄色毛茸,
Huaibei mild climate, suitable for planting soybean, but in soybean growth period, sometimes encounter short-term drought, in some years will also encounter high temperature and drought, seriously affecting the high yield of soybean. In order to find a way to fight drought from the variety itself, we have cultivated the soybean cultivars with strong drought resistance - Mengcheng 2 and Mengcheng 1012. Mengcheng 2 on the 2nd Mengcheng 2 is my field in 1966 from Suxian 647 soybean varieties selected mutant cultivated from the field. Currently in Mengcheng, Sui River and other counties to promote about 5 million mu, the general mu produce 300-400 pounds. Last year, there was a severe drought in our district with a long-term high temperature above 38 ℃. The output of many soybean varieties dropped drastically, and some varieties even got no yield. The yield of 206 kg per mu was 103.2% higher than that of Jinan No. 1 (20 kg per mu). Characteristics: Height about 55 cm, branches 4-5. Whole plant sticky yellow furry,
