一、浅水晒田与养鱼的矛盾稻田养鱼以稻为主。水稻分蘖期需晒田约7~10天,为使鱼的生长发育不受影响,可以实施“垄稻沟鱼式”稻田养鱼。即垄沟间隔和垄面沟底均为0.4米,沟面垄底为0.5米,沟深0.4米,合理密植秧苗。同时,晒田要轻晒、短晒。在晒田过程中,鱼饵料易缺乏,应在沟内投一些精料、鲜草。晒田后及时恢复水位。二、施肥与养鱼的矛盾施肥对鱼类影响较大,尤其是铵态氮肥。在实际工作中要“重施基肥,轻施追
First, the shallow water Sha Tin and fish conflicts Paddy fish to rice-based. Paddy tillering period of about 7 to 10 days, in order to make the growth and development of fish is not affected, you can implement the “ridge rice ditch fish” paddy fish farming. That is, the furrow spacing and ridge ditches are 0.4 m, 0.5 m ditch ridge, 0.4 m deep furrow, reasonable close planting seedlings. At the same time, Sha Tin to light sun, short sun. In the drying process, the fish is easy to lack of food should be cast some fine material in the ditch, fresh grass. After the tanning field in time to restore the water level. Second, the contradiction between fertilization and fish farming Fertilizers have a greater impact on fish, especially ammonium nitrogen fertilizer. In practical work to "heavy base fertilizer, light Shi chase
