Lotus root fertilization should pay attention to what

Lotus root growth and development are divided into three periods, namely, germination stage, prolonged period and crusting period. The budding period occurs from the germination of the plants to the emergence of the leaves. After the leaves, the new roots grow, mainly relying on the stored nutrients; the prolonged period from the plant leaves to the beginning of the knot, the nutrient demand is large, is the key period of topdressing; the knotting period from scab to harvest, Lotus seeds develop synchronously, nutrient absorption decreases, and stem and leaf nutrients are mostly transferred to earthworms and lotus seeds. According to this, a total of 3 times of fertilizer should be applied: before the planting, the base fertilizer will be turned into the field. Generally, the high-quality farmyard manure is 2000-3000 kg, and the general compound fertilizer is 40-50 kg. There are 2 times of topdressing: the first time is the vertical leaf fertilizer. When there are 3 to 5 pieces of standing leaves in the field, the application of nitrogen and phosphorus compound fertilizer is 25-30 kg, and the second time is the filling of nitrogen and potassium in the field. Sex compound fertilizer 30 ~ 35 kg. Linyi Fertilizer Network Copyright
