我市1978年从扬州地区农科所引进扬麦四号小麦试种。经过七年来的试验、示范、推广和不同气候年景的考验,证明该品种具有较好的适应性、丰产性和抗逆性。因此,栽培面积逐年扩大,83年实种53.5万亩,84年扩种到117万亩,占小麦播种面积的77.4%。平均实际单产达506斤,比上年小麦单产增加7.8%,合计增加总产4329万斤,占84年三麦增产总数的25.8%。现将84年大面积单产超五百斤的群体结构与主要栽培技术总结如
In 1978, our city introduced Yangmai No.4 wheat from Yangzhou Agricultural Science Institute. After seven years of experiments, demonstrations, promotion and weather trials of different climates, it is proved that the variety has good adaptability, high yield and stress resistance. Therefore, the area of cultivation has been expanding year by year, with an average of 535,000 mu in 83 years and 117 mu in 1984, accounting for 77.4% of the sown area of wheat. The average actual yield reached 506 kg, an increase of 7.8% over the previous year’s wheat yield, with a total increase of 43.29 million kg of total output, accounting for 25.8% of the total production of San Mai in 84 years. Now 84 years of large-area yield over 500 jin population structure and main cultivation techniques such as summary
