我们高强大队地处辽河沿岸,地势低洼、土质冷凉,庄稼一般成熟比较晚。特别是杂交高粱制种田的母本3197A,由于生育期长,成熟较晚,如收获不及时,晾晒不当,种子含水量降不下来,遇到秋季低温多雨和霜冻早来,往往造成坏种现象。 Our high-strength brigade is located along the Liaohe River coast, low-lying, cool soil, crop generally mature later. In particular, the female parent 3197A of hybrid sorghum farming, due to the long growth period, late maturity, such as the harvest is not timely, dry improperly, the seed moisture does not drop down, encountered low temperature and rainy autumn and early frost, often resulting in bad breeding phenomenon.
