解决稻田养鱼矛盾有三法:(1)妥善解决施肥与养鱼的矛盾。其主要措施是:重施基肥,巧施追肥;重施农家肥,巧施化肥。基肥的施用量应占总用肥量的70%,基肥应以人畜粪、绿肥、塘泥为主。特别提倡施绿肥。如用碳酸氢铵作底肥,应在施肥后6-7天放鱼进田。据测定:各种化肥在水深6厘米时,对3厘米长的鱼苗每667米~2安全用量为:硝酸钾25-75千克。过磷酸钾5-10千克,尿素5千克、硫酸铵10-15千克,石灰10千克。每次施化肥量控制在上述范围内,就比较安全可靠。
There are three ways to solve the contradiction of paddy field fish culture: (1) Properly solve the contradiction between fertilization and fish farming. The main measures are: heavy base fertilizer, Qiao Shi topdressing; re-implementation of manure, Qiao Shi fertilizer. Basal fertilizer application should account for 70% of the total amount of fertilizer, manure should be manure, green manure, pond mud-based. Special advocate green manure. Such as using ammonium bicarbonate as base fertilizer, should be put into the field 6-7 days after fertilization. It is determined: a variety of fertilizers at a depth of 6 cm, 3 cm long fry every 667 m ~ 2 safe dosage: 25-75 kg of potassium nitrate. 5-10 kg of potassium perphosphate, 5 kg of urea, 10-15 kg of ammonium sulfate and 10 kg of lime. Each time the amount of fertilizer control in the above range, it is more safe and reliable.
