七十年代以来,人们对我省长期肥稻稻连作提出了异议,并提出了向江、浙学习双三熟麦稻稻、油稻稻的经验。然而,肥稻稻、油稻稻、麦稻稻三者的关系究竟如何?彼此在生产上各占何等特定的位置?过去由于缺乏长期的试验研究,难以得出正确的结论。自1974年开始,我场在4.2亩稻田内设置了三熟制十年定位试验,以双(季稻)三熟各季轮作为中心,对我省有争论的肥稻稻连作及 Since the seventies, people have raised objections to the long-term cooperation of fertile rice in our province and proposed to learn the experience of double-cooked rice and oil-paddy rice from Jiang and Zhe. However, what is the relationship between fat rice, oil-rice and wheat-rice? What are the specific positions of each other in production? In the past, due to the lack of long-term experimental research, it was difficult to draw a correct conclusion. Since 1974, we have set up a three-year ten-year location test in 4.2 acres of paddy fields. With the double (quaternary rice) crops as the center,
