受巢湖水系影响的白湖圍垦区,垦殖已五年之久,计种稻十二万多亩。近年来,对荒湖圍垦区缺乏土壤有机质和土壤无机肢体的粉砂粘壤土,在圍垦种稻两、三年后又无缘肥补充的情况下,应该採取何种土壤耕作,是继續晒垡还是冬灌沤田(俗称冬沤田)?若进行冬沤对水稻产量扣土壤肥效影响如何?能否连年採用冬混土壤耕作?进行冬沤的操作要点又是什么?这一系列的生产实践問题出现后,引起了热烈的讨论,紧迫要求解决。为此,作者将我场圍垦种稻以来所积累的土壤资料,特别是1962年全饬冬沤田水稻栽培調查和试驗地观察研究结果作一分析。
Affected by the Chaohu Lake system reclamation area, reclamation has been five years, planted more than 120,000 mu of rice. In recent years, the shortage of soil organic matter and soil inorganic limbs silt clay loam for the reclamation area of abandoned barren, in the two or three years after the reclamation of rice and no fertilizer supplement, what should be tillage soil, is to continue the sun垡 or winter irrigation 沤 Tian (commonly known as winter 沤 Tian)? If the effect of winter 沤 on rice yield buckle soil fertility effect? Whether the year after the use of winter mixed soil farming? Winter 沤 operation What is the point? This series of production practices After the question appeared, it aroused heated discussion and pressed for urgent solution. For this reason, the author analyzed the soil data accumulated since the reclamation of rice in our field, especially the investigation of rice cultivation and experimental observation in the field in 1962,
