Delicious string beans. You can rest assured if you eat them at home.

Green beans are rich in protein and a variety of amino acids needed by the human body. they are often eaten to strengthen the spleen and stomach, and they also have the effect of relieving heat in summer. It is suggested that green friends breed green beans at home.

Green friends will have some confusion about the sowing, cultivation and construction of green beans. Next, let's learn some specific knowledge about the breeding of green beans.

I. seed treatment

Soak the green bean seeds in the sun for 2 to 3 days, then soak the seeds in 55 ℃ water for 15 to 20 minutes, during which the green friends should keep stirring. Finally, remember to soak the seeds at room temperature for 24 hours to improve the germination rate of the seeds.

Second, planting preparation

It is recommended that green friends choose potted containers with a depth of more than 15 cm and a diameter of more than 20 cm. The substrate can choose the soil that has planted flowers or vegetables before, but it must be sterilized by sunlight to reduce the germs in the soil in order to emerge.

Third, temperature and light

Phaseolus vulgaris is a temperature-loving plant, the suitable temperature for growth is 15 ℃ ~ 25 ℃, and the optimum temperature for flowering and pod setting is 20 ℃ ~ 25 ℃. The low temperature below 10 ℃ or the high temperature above 30 ℃ will affect the growth and normal pollination and pod setting of kidney bean. At the same time, Phaseolus vulgaris is a short-day plant, many of its varieties do not have strict requirements for sunshine length, and the cultivation season is mainly restricted by temperature.

IV. Water and fertilizer management

Green friends should carry out appropriate water and fertilizer management according to the seedling conditions of green beans, and the principle is "dry flowers and wet pods, pre-control and post-promotion." after the green beans bear pods, they should keep the soil moist and apply urea every half a month. you can also spray foliar fertilizer potassium dihydrogen phosphate, and when the plant enters the aging period, we should remove the old, residual and diseased leaves of the plant in time to reduce nutrient consumption.

Fifth, set up a frame to draw vines

When the vine is 25cm long and 30cm long, two bamboo poles should be inserted around the kidney bean plant and crossed to form a "human" shaped frame with a height of more than 2 meters. Green friends should remember to draw the vine on the shelf in time.

VI. Harvest

Green beans grow so fast that they can be harvested 10 days after flowering, and they are harvested every 1 to 2 days. If we do not harvest them in time, the quality of green beans will decline, the fiber of pods will increase, and the beans will grow old. the edible effect will also become worse.
