The planting prospect of mung bean is broad, the growth cycle is more than two months, and it has strong adaptability and is very easy to plant.

so what are the sowing methods of mung beans? How to manage mung bean planting? Let's take a look at it together!

planting time of mung beans

mung beans have short growth period and long sowing period, which can be sown in spring or summer in many places.

Generally, seeds can be sown when the ground temperature reaches 16 ~ 2℃.

The sowing date for planting mung beans in most plots with irrigation conditions is from May 15th to 3th, and in Shagang plots without irrigation conditions, the sowing date is from June 12th to 15th. Generally, the sowing date is from late April to early and middle May, and the sowing date is from late May to early and middle June in summer.

in the north, the suitable sowing period is short, and the annual spring sowing period is from early May to the end of May, and the summer sowing period is from late May to early June.

Spring sowing in Northeast China is in the middle of May, and summer sowing is in the middle and late June.

Note that mung bean is a warm crop. If it is sown too early in spring, the individual will be stunted, the growth period will be prolonged and the yield will be reduced.

It is better to sow mung beans early in summer. The seedlings grow healthily, and the flowering and pod setting stage is in a high temperature and rainy stage, which is beneficial to the formation of flowers and pods, with more pods, more grains, higher grain weight and higher yield.

sowing method of mung bean

1. Fine soil preparation: mung bean is a dicotyledonous plant with large cotyledons and weak ability to top the soil.

Therefore, before sowing, it is necessary to carefully prepare the soil, and achieve the purpose of leveling the ground and making the soil fine, making the upper part empty and the lower part solid by turning, harrowing and pressing.

if there is water irrigation condition, it is necessary to build soil moisture, and if there is no water irrigation condition, it is necessary to prepare the soil in advance and wait for the rain to sow.

Generally, soil preparation is carried out in the first half of April.

2. seed treatment: before sowing, diseases, impurities and hard grains should be removed to ensure the purity and germination rate of seeds.

The seeds are selected by air, water or machine, and the grains, small grains, impurities and grass seeds are cleaned, and the clean big seeds are selected for sowing.

spread the seeds thinly on a sunny day and turn them over for 1-2 days to enhance the vigor of the seeds and improve the germination potential.

Rub the "iron mung bean" with dark color, rough skin and poor water absorption, which is not easy to germinate, so that the seed coat is slightly damaged and easy to germinate and emerge.

sprinkle a small amount of water on the seeds, and sprinkle the microbial inoculum on the wet seeds and mix well.

Rhizobium fertilizer should not be mixed with chemical fertilizer and bactericide.

The dosage of common nitrogen-fixing bacteria per gram contains 3 million rhizobia, and the dosage per mu is 125 grams.

or seed dressing with coating agent, drought-resistant agent or microelement fertilizer containing molybdenum and boron.

3. Sowing method: Generally, mung beans can be sowed when the ground temperature reaches 16 ~ 2℃.

Spring sowing is in May, and the earlier summer sowing mung beans are sown, the higher the yield will be.

most of them are drill sowing, hole sowing and broadcast sowing.

drill sowing should prevent the soil from being covered too deeply, the seeds from being planted too thick and the sowing from being missed.

Intercropping, interplanting and sporadic planting are mostly hole sowing.

the sowing depth is generally 3 ~ 5cm.

the amount of seeds used per mu is 1 ~ 2kg, with less fertile land and more thin land.

field management of mung beans

1. Replenish seedlings: After sowing, the plots with poor moisture content should be suppressed in time, so that the seeds can be in close contact with the soil, increase the surface moisture, promote seed germination and development, and emerge early and complete seedlings.

after the emergence of mung beans, it is found that there is a phenomenon of lack of seedlings and broken ridges, and the replanting should be completed within 7 days.

2. Seedling thinning and seedling fixing: In order to make the individual seedlings develop well, when mung beans reach two leaves and one heart after emergence, the lump seedlings should be removed.

when four leaves are planted, the plant spacing should be 13 ~ 16 cm, and the row spacing of single cropping should be about 4 cm.

according to the established density, remove weak seedlings, diseased seedlings, small seedlings, miscellaneous seedlings and weeds, and keep strong seedlings.

the practice of reserving seedlings for one plant is beneficial to the robust growth of plants.

3. intertillage weeding: it can not only eliminate weeds, but also break soil hardening, loosen soil, reduce evaporation, increase ground temperature and promote nodule activity, which is a measure to increase mung bean production.

generally, after the first compound leaf of mung bean is unfolded, the first shallow hoe is combined with the thinning seedlings. After the second compound leaf is unfolded, the seedlings are fixed and the second intertillage is carried out. At the branch stage, the third deep intertillage is carried out, and the roots are sealed and the soil is raised. The intertillage should be carried out until the ridge is sealed.

the principle of shallow-deep-shallow should be mastered in the depth of intertillage.

4. Irrigation and waterlogging prevention: Mung bean is a crop that needs more water, is not tolerant to waterlogging and is afraid of flooding.

Mung bean has strong drought resistance at seedling stage, and needs less water, and the peak water demand is at flower and pod stage.

at this time, water should be poured in time in case of drought.

but mung beans are afraid of waterlogging and flooding.

If there is too much water in the seedling stage, the root diseases will be aggravated, resulting in rotten roots and dead seedlings.

In the later period, when waterlogging occurs, the plants grow poorly, premature senescence occurs, flowers and pods fall off, and the yield decreases.

Therefore, mung beans should be drained to prevent waterlogging in rainy season.
