What kind of fertilizer is good for mung bean base fertilizer (base fertilizer application method)

The role of mung bean fertilizer

Mung beans have a relatively large demand for fertilizers, especially nitrogen fertilizers. Therefore, when planting, the three main fertilizers of nitrogen, phosphorus and potassium are applied. The amount of nitrogen fertilizer is slightly more, and the other two fertilizers are evenly matched to ensure smooth growth and improve yield and quality.

Mung bean fertilizer selection

The best base fertilizer for mung beans is human feces, wood ash, kang soil, and decomposed pig, chicken, sheep manure and other farmyard manure. Apply 10-15t per hectare. Topdressing should be timely and appropriate, suitable for the seedling stage and the initial flowering stage of mung beans, mainly nitrogen and phosphorus fertilizers. Dig furrows between the rows and apply appropriate amounts of urea or compound fertilizers.

How to apply mung bean base fertilizer

To fertilize mung beans, you must choose the right time. From September to before leaf fall is the best time to apply base fertilizer. The earlier you apply it, the better the effect.

Nitrogen and phosphorus fertilizers should be applied during the initial flowering period of mung beans. Apply 10 kg of nitrogen-phosphorus compound fertilizer per mu, or spray 1-2 kg of urea plus 1 kg of potassium dihydrogen phosphate per mu. Do it in 2-3 times, 0.5-1.0 kg of urea and 400-500 grams of potassium dihydrogen phosphate each time, add 60-65 kg of water and spray. In addition, trace element fertilizers should be applied. Generally, 5 kg of trace fertilizer can be applied per hectare as base fertilizer.

How much mung bean base fertilizer should be added

Generally, apply 25 cubic meters of well-decomposed organic fertilizer, 100 kilograms of diammonium phosphate, 50 kilograms of mixed urea, and 50-75 kilograms of potassium sulfate per hectare on mung bean soil with medium fertility. Or apply 25 cubic meters of organic fertilizer and 300 kilograms of mixed high-efficiency compound fertilizer per hectare. The amount of chemical fertilizer can be reduced appropriately.

How to apply fertilizer to mung beans

If no base fertilizer is used for mung beans, you can apply about 10-15 kg of nitrogen, phosphorus and potassium controlled-release fertilizer after the first fully expanded compound leaf appears. Try not to use urea alone as topdressing. You can appropriately increase the content of phosphorus fertilizer and potassium fertilizer.
