利用杂交中稻进行再生稻栽培,具有省工、省时、低成本的优点。是川东南长江一带河谷及部分浅丘地区充分利用水热资源,夺取两季高产的好措施。去年省政府把再生稻栽培作为抗旱夺丰收的重要措施之一,为了减少旱灾造成的损失,曾号召上述地区种植再生稻,并每亩拨给尿素2.5公斤作为保证措施。结果在23个县69.8万亩面积上取得了平均亩产75.5公斤,24万亩面积上获得亩产100公斤以上,总产达到0.53亿公斤的好成绩。这一情况表明过去的再生稻种植技术是成功的。但从最初一些专家的估计,全省适宜种植再生稻的面积约250万亩,单产可达到200公斤
The use of hybrid rice in ratooning rice cultivation, with labor, time-saving, low-cost advantages. It is a good measure to make full use of water and heat resources in the valley of the southeastern part of the southeastern part of Sichuan Province and part of shallow hill regions to seize high yield in two seasons. Last year, the provincial government put the cultivation of ratooning rice as one of the important measures to end drought and harvest. In order to reduce the losses caused by drought, it has been called for planting ratooning rice in the above-mentioned areas and allocating 2.5 kilograms of urea per mu as a guarantee measure. As a result, an average yield of 75.5 kg per mu was obtained in 698,000 mu of 23 counties and a good result of gaining more than 100 kg per mu in 24 million mu of land and a total output of 0.53 billion kg was achieved. This situation shows that past ratooning rice cultivation techniques were successful. However, some experts from the initial estimates, the province suitable for planting ratoon area of about 2.5 million mu, yield can reach 200 kg
