First, fresh water irrigation, scientific water use. Green food rice must be irrigated with natural water, and it must not be used for industrial wastewater and domestic sewage irrigation.
Second, a reasonable fertilization, early life and fast hair. The principle of rice fertilization is to “eat less mealsâ€, control the supplements and control after the former, combine agricultural fertilizers, chemical fertilizers, biological fertilizers, combine nitrogen, phosphorus, and potassium. Grade A green foods are allowed to use chemical fertilizers, but they must be used in limited amounts. AA grade green Food can not use chemical fertilizers, only agricultural fertilizers and biological fertilizers. The application of chicken manure in paddy fields is good, but the dosage should be appropriate, the time should be grabbed before, the application should be uniform, and the fermentation is good. Generally, about 1,000 kilograms per acre is applied, fresh feces can be less, and Chen can be more.
The rice Honda top dressing is divided into phases, which are roughly divided into tiller fertilizer, control fertilizer, panicle fertilizer, and grain fertilizer. Green food rice should chase organic fertilizer, fine fertilizer and biological bacterial fertilizer, promote fertility, mature earlier, increase yield, and improve quality.
Third, eliminate weeds and promote fertility. There are many kinds of weeds in paddy fields, so we must strictly select them. We must choose “three certificates, high efficiency, low toxicity and low residual herbicides. AA grade green food rice cannot be weeded with chemical herbicides, and weeding should be done manually. , Mushrooms three times, the late cut the grass pond grass and channel weeds, the use of air and light transmission, improve the utilization of photosynthetic.
Fourth, disease prevention and pest control, insects gain food. Pest control is mainly biological and physical and artificial methods to control pests and diseases. The rice leaf miner can be irrigated with shallow water, or it can be removed from the parasitic pond grass. Rice blast should conduct field investigations. Once it occurs, biological pesticides can be used for prevention and control. For example, it can be prevented and cured by using grey lecithin, and furnace ash and white lime can be used for prevention and control. The method is to mix evenly in a ratio of 4:1. In the onset of disease on the site, every 5 days, a total of 2 to 3 can be raised.
