Bean top dressing technology

First, an appropriate amount of nitrogen fertilizer should be applied in the early stage of growth. Rhizobium in the roots of kidney bean seedlings has weak nitrogen-fixing ability, and the application of appropriate amount of nitrogen fertilizer can promote early plant growth and robust growth. However, if the plant grows vigorously, it is necessary to control or not use nitrogen fertilizer, in order to prevent the vegetative growth of the plant from being too popular, which may cause delayed flowering, falling flowers or delaying the fruit.

The first top dressing should be mastered in the first inflorescence bud period, 10 kg of urea or a proper amount of manure. When the pod grows to 3-4 cm long, it is the continuous topdressing after the flowering result period. According to the different mouth and plant growth conditions, the topdressing is generally performed every 10-20 days.

Manure and compound fertilizer should be used alternately, the amount of manure is appropriate, and the compound fertilizer is 10-20 kg/mu.

Top dressing is better with water and top dressing, which is good for dissolution. Water should be poured once in the middle of the top dressing to promote photosynthesis and meet the needs of rapid growth of the pods. In addition to root fertilization, foliar fertilizer can also be used for foliar application, and the effect is also obvious.
