Correct Fertilization Methods and Technical Key Points for Mung Beans
Mung bean is a common legume in daily life. It can be made into many delicious foods and has high nutritional and economic value. When growing mung beans, fertilization is an important point, as it affects the yield and quality of mung beans and indirectly affects farmers' income. So how should mung beans be fertilized? Let's take a look.
1. Fertilizer Requirements
Mung bean is a crop with a relatively high fertilizer demand. According to research, for every 100 kg of mung beans produced, 9.68 kg of nitrogen, 2.93 kg of phosphorus, and 3.51 kg of potassium are absorbed. Therefore, when planting, the three main fertilizers - nitrogen, phosphorus, and potassium - are applied, with nitrogen fertilizer as the main one, evenly combined with the other two fertilizers, so that growth proceeds smoothly and yield and quality are improved.
2. Fertilization Principles
Mung bean is a deep-rooted plant with large cotyledons, so during planting the soil must be strictly prepared by deep plowing and fine harrowing, keeping the soil loose on top and firm below with uniform depth, to facilitate smooth emergence. Mung bean itself has rhizobia and can fix and absorb nitrogen on its own, but fertilizer still needs to be applied, otherwise the yield will be low. When fertilizing, the principles to follow are: mainly farmyard manure with inorganic fertilizer as a supplement; mixed application of farmyard manure and inorganic fertilizer; and applying sufficient base fertilizer with timely topdressing.
3. Fertilization Methods
Before planting, the soil should be plowed, and at this time base fertilizer is applied. The base fertilizer is mainly farmyard manure such as human excrement and urine, plant ash, and livestock manure, applied at 1000-3000 kg per mu. Topdressing is generally done at the seedling stage and flowering stage. Fertilizing at the seedling stage can make seedlings grow quickly and robustly, applying 10 kg of urea or high-nitrogen compound fertilizer per mu each time, with corresponding increase or decrease according to actual conditions. During the branching and flowering-podding stages, foliar fertilizer can be sprayed. The foliar fertilizer can use urea and potassium fertilizer combined with other trace elements, so that the plants can absorb it as quickly as possible and the fertilizer utilization rate is improved.
4. Fertilization Precautions
Phosphorus fertilizer can promote robust growth of mung bean plants, increase branching and pod-setting rates, and improve yield, but mung bean is extremely sensitive to phosphorus fertilizer, so it should not be applied too much at one time. When applying base fertilizer, 20-25 kg of superphosphate can be applied per mu, mixed with the base fertilizer, so as to provide phosphorus supply for the plants throughout the entire growth period.
