Scientific fertilizer control

With a well-developed organic fertilizer as a base fertilizer, lime powder is added to 20 kg per cubic meter of manure, and the mixture is thoroughly mixed. Afterwards, the deep field application can reduce spawning of the flies and effectively reduce the damage of the earthworms. It also advocates the use of commercially available organic fertilizers and organic-inorganic compound fertilizers sold in the market.

Choose early spring or after the leek harvest, sprinkle the ash (without rain) on the surface, mix the ash thoroughly and mix the ash into the soil, or open the ditch (appropriate to see the root) into the ditch, cover the soil cover strict. The application of ash to alfalfa is not conducive to alfalfa life, so it has a preventive and control effect, loosens the soil, increases the content of phosphorus and potassium fertilizers, and can make young leek seedlings strong and increase yield.

During the growth of leeks, 15-25 kilograms of ammonia per acre, diluted by 80-100 times, and irrigated or flushed with water, have the effect of killing fleas. In combination with watering, 15-20 kg ammonium bicarbonate can be topdressed with water, which can also effectively kill larvae.

Every time you harvest a leek, immediately use fresh urine to pour the vegetables. When the soil is moist, it is not water, and when the soil is dry, it is 50% water. After pouring, it should be protected by a piece of vegetation ash. In this way, the soil surface is often in a dry state, and the tiny eggs cannot hatch. Suitable for small farmers to implement.
