荒湖区粉砂粘壤型水稻土冬灌漚田,在漚田期間发生断水,称为断水漚田。对于这种断水漚田的水稻效应(即水稻营养生长和生殖生长表現效果的总称)以及土壤肥效影响问题,作者曾做过調查和研究。現将所获材料逐款分析如下。一、断水漚田的水稻效应在漚田水稻效应調查中看出,不断水漚田与断水漚田,以及不同断水时期、断水时間、断水次数的漚田,它們的水稻效应都存在着一定差异。(一) 断水沤田与不断水沤田的水稻效应调查証明:断水漚田的水稻效应远较不断水漚田的差;几乎与晒垡耕作的水稻效应相近
Desert Lake area silt clay soil type paddy winter irrigation Tian, occurred in the field Tian water, known as the water cut Tian. The authors conducted a survey and study on the rice effect (a collective term for the effect of vegetative and reproductive growth in rice) and the effect of soil fertility on this water-cut field. The materials obtained are analyzed as follows. First, the paddy field water cut effect In the paddy field rice effect survey found that continuous water riparian and water cut 沤 Tian, as well as different water-off period, water-off time, the number of water-cut 沤 Tian, their rice effects there is a certain difference. (A) the water cut Tian and continuous Minagawa paddy field survey showed that: paddy field paddy rice effect is far less than the continuous Minamata field; almost the same effect of sun drying rice cultivation
