Do you need to soak the seeds to grow mung beans?

First, the seeds need to be soaked before planting mung beans, which reduces the water absorption process of seeds in the soil, accelerates the germination process of mung beans and reduces the excavation time.

Second, mung bean cultivation techniques:

(1) variety selection

Traditional mung beans are mostly creeping or semi-creeping, and the pods are fried when they are mature, which is not conducive to large-scale planting. In order to facilitate field management and harvest, improve yield and commodity characters, we should abandon farm varieties and choose upright mung bean varieties, such as Jimengdou No.2 from Baoding Agricultural Institute and Lv Zhong 1 from Asian Vegetable Center. These varieties stand upright, resist lodging, do not burst pods after maturity, are suitable for centralized harvesting, can reduce the rodent damage and mildew of seeds, and stabilize and yield high. Experiments show that if improved varieties are combined with good methods, the yield of these varieties is generally higher than that of farm varieties by more than 40%.

(2) timely sowing

The growth period of mung beans is short, generally about 60-70 days. You can choose spring sowing and summer sowing. Mung beans can be planted from April to July. Ji Mung Bean No.2 has a short growth period, and can be planted twice a year in the central and southern areas of Hebei Province, and can even be used as a disaster relief crop for crops such as corn. According to the records of Baoding Academy of Agricultural Sciences, Lv Ji No.2 was sown in the cotton field damaged by hail in Gucheng County of Hengshui on July 20th, and the yield per mu was still 97kg. It is customary to sow the next crop of wheat in central Hebei, and the suitable sowing date is from June 20th to July 1, and it will mature in mid-September, so as to ensure that the next crop of winter wheat will not become the main crop.

Artificial hole sowing can be used for small area sowing, and machine sowing can be used for large area sowing. 2.5 kg of seed for drilling per mu, hole sowing 1.5 kg, sowing depth of 3.3 cm, row spacing of 50 cm, and plant spacing 17 cm. Based on the density of 8,000 plants per mu, early sowing in spring should be appropriately sparsely planted, plots with large fertilizer and water capacity should be sparsely planted, and plots with poor water and fertilizer should be densely planted, but the density should be between 6,000-10,000 plants per mu, otherwise the yield will be seriously affected. After emergence, interplanting and replanting should be done in time, and seedlings should be fixed in time when two three-leaf compound leaves are unfolded.

Continuous cropping of mung beans will cause weak growth and serious diseases, which will affect the yield. It is best to replant mung beans every 2-3 years after the last multiple cropping. Pay attention to applying base fertilizer, especially phosphate fertilizer, to protect seedling fertilizer and Miao Zhuang, and realize high and stable yield.

(3) Site management

Traditional mung bean planting ignores water and fertilizer management, and the vegetative growth of erect varieties is weak, so attention should be paid to the application of base fertilizers (N, P, K). If the growth is good in the middle and late stages, there is no need for topdressing. If it is found that the field population is too wet to be closed, topdressing 15% NPK compound fertilizer 10- 15kg/ mu can be done in time, and furrow fertilization is best. After flowering, in case of drought, water properly, and pay attention to drainage in case of waterlogging. Before closing the ridge, intertillage can be combined with weeding, usually about 2 times.

Among the main cultivars in our province, Jimung bean No.2 and Lv Zhong 1 have better disease resistance. The pests in seedling stage are mainly cutworms, aphids, cotton bollworms, borers, borers and bean moths, and 40% omethoate 1200- 1800 times can be sprayed for control. From the flowering stage, pyrethroid pesticides (such as 2.5% Kung Fu EC) 1500 times, 40% omethoate oil 1200 times and 50% methamidophos 1800 times are mixed and sprayed once every 7- 10 days, generally three times.

Mung beans have a strong habit of primary pod setting. If pests and diseases, drought and other disasters affect the early pod setting, proper management in the later stage can also form secondary pod setting, or form a hectare of yield and reduce losses.

Mung beans can be sealed with herbicide cables after sowing and before emergence, and herbicides such as Gaicaoneng can be used to weed after emergence. The variety and dosage of herbicide can refer to soybean. Mung beans are sensitive to pesticides and herbicides, so the dosage should be strictly controlled to prevent phytotoxicity.

In addition, 0.2% chlormequat or Zhuangfengling spray can be used to shorten the pitch, prevent serious lodging, control nutrient transfer and achieve high and stable yield.

(4) harvesting in batches

Mung beans are not concentrated in maturity, which is suitable for picking horns in batches. For large-scale cultivation, most pods can be harvested once in wet weather when the weather is dry, and then dried by mechanical colloidal particles. When the goods are stored, they can be fumigated with drugs such as aluminum phosphide to prevent elephants from being damaged. In addition, mung beans are conventional varieties. If it is to be kept as seeds, it should be artificially purified in the field at the early stage of maturity to remove exotic plants to ensure the purity of seeds.
