在农业学大寨运动的推动下,我县双三熟制生产随着品种的更新、施肥水平的提高和关键措施的落实,正朝着稳产高产的方面前进.但是部分地区在双三熟制的布局茬口上,仍存在不少问题,突出的表现是:不从当地情况出发,片面追求提高复种指数,扩大麦稻稻硬三熟,忽视了养地,形成了抓这熟丢那熟,地力日趋下降,土壤结构变坏,水稻单产也难以提高的局面.这些地区总产的增加,主要依靠扩大面积,广种薄收.并由于油菜绿肥面积减少,有机肥料不足,多用商品肥料,农业成本增加.就全县而言,从1965—1973年,粮食总产增加83%,复种指数从55%提高到207%,而粮食单产只上升50%;土壤含氮量从1.8%下降到1.3%;农本从每斤粮食三分二厘增加到三分八厘以上,少数单位达到六分左右;农业用工量也显著增加. Driven by the Agricultural Science Dazhai Campaign, the production of Shuangsan Cooked Rice in our county is moving forward with steady production and high yield as the varieties are updated, the fertilization level is improved and the implementation of key measures is implemented. However, in some areas, There are still many problems on the layout of Crops. The outstanding performance is that we should not proceed from the local conditions and unilaterally pursue and raise the index of multiple cropping, With the decline of soil fertility and deterioration of soil structure, yield per unit area of ​​paddy rice is also hard to be increased, and the increase of total output in these areas mainly depends on the expansion of area and the wide variety of thin harvests. For the county as a whole, from 1965 to 1973, total grain output increased by 83%, and the multiple cropping index increased from 55% to 207% while grain yields rose only by 50%; soil nitrogen content dropped from 1.8% to 1.3% This from two cents per catty grain increased to more than three eighths, a few units to reach about six; agricultural employment also increased significantly.
