黑龙江省是我国重要的春麦产区,播种面积3000方亩以上。东部和北部国营农场又以小麦为主要粮食作物,播种面积占50—60％。收获时期正逢雨季,中熟和晚熟品种过多是,因不能及时收获会造成重大损失。研究表明,早熟品种可以躲开雨季,产量稳定性好。另外,广大低湿易涝地、坝外沿江地也都需种植高产的早熟品种。为满足生产需要,从1973年起开展了辐射选育早熟、高产、优质小麦新品种的研究,1985年定名为“龙辐麦2号”。
Heilongjiang Province is an important spring wheat producing area in China with sown area of more than 3,000 mu. In the eastern and northern state farms, wheat is the main grain crop with sown area of 50-60%. Harvest period is coincided with the rainy season, too ripe and late maturing varieties are, because they can not be harvested in a timely manner will cause heavy losses. Studies have shown that early maturing varieties can escape the rainy season, yield stability. In addition, the majority of low wet and easy waterlogging, dam along the river also need to grow high yield of precocious varieties. To meet the production needs, from 1973 onwards launched a radiation early maturity, high yield, high quality wheat new varieties of research, in 1985 named “Long Fu Mai 2”.
