Is green beans suitable for planting in Guigang, Guangxi?

Kidney beans (kidney beans) are suitable for planting in Guigang, Guangxi, and are widely planted in China.

Analysis and explanation:

Beans can be widely planted in the north and south of China.

Kidney beans like warmth and are not resistant to frost.

The temperature range of seed germination is 20-30℃, and it cannot germinate below 10℃ or above 40℃.

Seedlings are sensitive to temperature changes. In a short time, they began to lose their green color at the low temperature of 2-3℃ and were frostbitten at 0℃.

Bean has developed root system and many lateral roots, and its drought tolerance is greater than its waterlogging tolerance.

Seed germination needs to absorb enough water, but too much water, lack of oxygen in the soil, and seeds are easy to rot.

The suitable field water-holding capacity in plant growth period is 60-70% of the maximum water-holding capacity, and the water requirement in flowering period is strict, and the suitable air relative humidity is 65-80%.

Kidney beans are most suitable for planting in deep, soft soil with rich humus and good drainage.

It belongs to subtropical monsoon climate zone, with annual average temperature of 265,438 0.5℃, annual average rainfall days of 65,438 0.66 days, annual average rainfall of 65,438 0.600 mm and frost-free period of 353 days.

Therefore, this area can be planted, and attention should be paid to flood control and drainage.

Cultivation time (spring and autumn):

February-April (autumn sowing can also be carried out from August to September).

The northeast is from late April to mid-May.

Most parts of northwest and north China are in April.

The northern plateau is in early May.

East China from late March to early April.

Most areas in Central China and Southwest China are from late February to early March.

Yunnan is 65438+1from late October to early February.

65438+ South China February-April.

North China and northwest China are in early July-August.

Central China from late July to early August.

East China from late July to early September.

Southwest in early August.

South China from late August to 10.

Seedling raising:

It can be used for direct seeding or seedling transplanting, with 3-4 seeds per hole, covered with soil about 2 cm, kept moist, and sprouted about 1 week. If the weather is too dry, it can be covered with plastic film to keep moisture.

If you want to transplant, you should transplant as soon as possible when 1 unfolds the true leaves. Because the root regeneration ability is weak, water it after planting.

Growth management:

Strict requirements for water, like wet but afraid of drought, avoid waterlogging.

Before flowering, there should be less water, generally no watering.

Water more from flowering to pod setting, generally every 2 ~ 3 days 1 time, and increase the watering times when the temperature is high.

Fertilization can usually be combined with watering. In the early stage of growth, the decomposed organic fertilizer mainly containing nitrogen fertilizer should be topdressing 2-3 times, and the decomposed organic fertilizer should be sprayed every 1-2 weeks/time, which requires a nitrogen, phosphorus and potassium compound fertilizer.

When the growth temperature is higher or lower than 1.5 ~ 20, it is easy to drop flowers. Summer needs shade to cool down, and it is forbidden to get wet for a long time at low temperature.

Dwarf varieties don't need to be equipped with supports, and creeping varieties can be equipped with supports or vines to climb scaffolding or railings when the plant height is 1.5 ~ 20 cm.

Pods with a length of about 10 cm can be harvested about10 days after the flowers wither.

When harvesting, grab the pedicel with one hand and pinch off the pod with the other. Be careful not to pull the stems and vines hard.
