A good way to resolve the contradiction between rice and fish in paddy fields

The rice field fish farming industry of Fang Xing Moi has opened up a good way for farmers to make better use of the limited cultivated land and increase the income of planting and breeding. However, in actual operation, due to the need for drying, fertilization, and disease prevention and extermination in paddy rice production, it has caused many problems for fish farming and even caused undue losses. The concrete measures to resolve these contradictions are described below.
(1) When drying the fields, the soil dryness and humidity controlling the ineffective delivery should be taken into consideration, and the water needed to ensure the normal life of the fish should also be taken into consideration. The solution is to dig in the paddy fields the “Tian” and “Well” shaped swimming fish ditch and about 10 square meters of fish larvae, so that the ditch and ditches can communicate with each other and the gully can be connected. I live in normal life. After the drying of the field, fill the field with water in time.
(2) When fertilizing, be careful not to waste fertilizer. It should also not affect the growth of fish. In the application of chemical fertilizers, shallow field water can be discharged first to concentrate the fish into the fish ditch and fish gills and fertilize, so that the applied chemical fertilizer can quickly sink into the field mud, and then deepen the field water to normal depth; or take a small amount of times, Fragmentation, top dressing and other methods can also be used organic fertilizer as top dressing.
(3) When spraying pesticides, it is necessary to be able to kill pests and diseases but also to prevent fish from being poisoned by pesticides. This requires the selection of highly effective and low-toxicity pesticides such as trichlorfon, dimethoate, leaf glycosides, methamidophos, rice bran, jinggangmycin, etc., and the amount of medication used for the routine use of rice pests and diseases. Do not use pesticides that are strongly toxic to fish, such as sodium pentachlorophenol, fish extracts, and phenolics. When pesticides are sprayed, the field water should generally be deepened to more than 6 cm before spraying to reduce phytotoxicity. Aqueous solutions and emulsion pesticides should be sprayed in the afternoon after the dew is dry, with the sprayer facing upwards; dust pesticides should be sprayed when the dew on the rice sprouts is not dry in the morning, so that the pesticides can adhere to the surface of rice leaves and reduce the amount of pesticides dissolved in the water. . It is also possible to lure the fish into the fish ditch and fish gills when pesticides are applied, and then return the fish to the rice paddies after the disappearance of the drug, or to apply the pesticides in divided batches, that is, to apply half of the paddy fields first. After a few days, the other half of the paddy fields will be used to protect the fish from phytotoxicity, and rice and fish will be safely double-crossed.
