Fertilization methods of mung bean

Mung bean is a common bean in daily life, which can produce a variety of delicious foods and has high nutritional and economic value. Fertilization is an important point when planting mung bean, which is not only related to the yield and quality of mung bean, but also indirectly affects the income of farmers. So how to fertilize mung beans? Let's take a look.

1. Characteristics of fertilizer requirement

Mung bean is a crop that needs a large amount of fertilizer. according to research, for every 100 kg of mung bean, it is necessary to absorb 9.68 kg, 2.93 kg of phosphorus and 3.51 kg of potassium. Therefore, when planting, three kinds of nitrogen, phosphorus and potassium fertilizers are mainly applied, of which nitrogen fertilizer is the main fertilizer, which is evenly mixed with the other two fertilizers to make it grow smoothly and improve its yield and quality.

2. Principles of fertilization

Mung bean is a deep-rooted plant, and the cotyledons are hypertrophic, so it is necessary to strictly prepare the soil, turn the soil deep and rake fine, so that the soil is in a state of consistency in depth and depth, so as to facilitate the smooth emergence of seedlings. Mung bean itself has rhizobium, which can fix and absorb nitrogen, but still need to apply fertilizer, otherwise the yield is low. When fertilizing, we should follow the principles of farm manure, inorganic fertilizer, mixed application of farm manure and inorganic fertilizer, adequate base fertilizer and timely topdressing.

3. Fertilization method

The soil should be ploughed before planting, and the basic fertilizer should be applied at this time. The basic fertilizer is mainly farm manure of human feces and urine, plant ash and livestock fertilizer, with 1000-3000 kg per mother. Topdressing is generally in the seedling stage and flowering stage, fertilization in the seedling stage can make the seedlings grow fast and strong, applying urea or high nitrogen compound fertilizer 10 kg per mu each time, increasing or decreasing accordingly according to the actual situation. In the branching and flowering and podding stage, foliar fertilizer can be sprayed, and foliar fertilizer can be used with urea and potash fertilizer with other elements, which can make the plant absorb as soon as possible and improve the fertilizer use efficiency.

4. Pay attention to fertilization

Phosphate fertilizer can promote the growth of mung bean plants, increase the branching and podding rate, and increase the yield, but mung bean is very sensitive to phosphate fertilizer and should not be applied more each time. When applying base fertilizer, 20-25 kg calcium superphosphate per mu is applied and mixed with base fertilizer, which can provide the supply of phosphorus for the whole growth period of the plant.
