What is the height of the green bean crop? Green bean planting time and method temperature

Green bean is another name for kidney bean, and Phaseolus vulgaris is a cultivar of the leguminous bean family, which is an annual herbaceous plant. It is mostly called eyebrow peas in the north, and it is also called eyebrow peas in Lanxi, Zhejiang. It is also called kidney beans, kidney lentils, April beans, etc., which are called Qingming beans in Quzhou, Zhejiang, and green beans in Sichuan and some central China, and are one of the common vegetables on the table.

Cultivation techniques. Planting season.

February-April (autumn sowing is also possible in August-September). The specific spring sowing period is as follows: the Northeast growing ** area is from late April to mid-May; Northwest and most of North China in April, and in the Northern Plateau in early May; East China from late March to early April; Late February to early March in most parts of central and southwestern China; Yunnan in late January to early February; December to April of the following year in South China.

Autumn sowing: July to early August in North China and Northwest China; , late July to early August in central China; East China from late July to early September; Early August in the southwest region; Late August to October in South China.

Seedling. 1. It can be seeded or transplanted seedlings, 3 4 seeds per hole, covered with soil about 2 cm, kept moist, about 1 week of seedlings, if the weather is too dry, it can be covered with film and moisturized.

2. If you want to transplant, you should transplant as soon as possible, when the first pair of true leaves can be transplanted, because the root regeneration ability is weak, and it should be watered thoroughly after planting.

Growth management. 1. Strict requirements for moisture, like humidity and fear of drought and waterlogging. Watering should be less before flowering, generally not dry or watering; It is necessary to water more from flowering to podding, generally once every 2 3 days, and increase the number of watering times when the temperature is high.

2. Usually fertilization can be combined with watering, top application of Trim nitrogen fertilizer 2 3 times in the early stage of growth, spraying nitrogen fertilizer every 1 2 weeks from flowering to pod-setting stage, requiring nitrogen, phosphorus and potassium compound fertilizer.

3. The growth temperature of 1 5 20 is higher or lower than that of flowers, and it is necessary to shade and cool down when the high temperature is high in summer, and avoid long-term rain at low temperature. Dwarf varieties do not need to be supported, and creeping varieties can be used to set up scaffolds or tow vines to climb trellises or railings at a height of 1 5 20 cm. About 10 days after flowering, the pods are about 10 cm long and ready to be harvested.

When harvesting, grasp the flower stalk with one hand and pinch the pod off with the other, taking care not to pull the stem and break it.

4. Ridge formation and mulching planting.

Green bean pods are bar-shaped, slightly swollen, 10-15 cm long.

Green bean planting time and method temperature

1.Seeding time.

Green beans are usually sown in spring and autumn, in February-March or August-September, when the climate is mild and more conducive to plant growth.

2.Growing environment.

Green beans prefer a warm environment, but are not frost tolerant, and the most suitable germination temperature for seeds should be kept at 20-30, and the temperature is below 10 or above 40, it is not allowed to germinate.

3.Cultivation method:

The planting method of green beans is very simple, generally sowing seeds in the way of sowing, evenly sowing the seeds on the soil, then covering a thin layer of soil, and gently compacting, and then watering enough, watering can not be too much, to avoid the phenomenon of water accumulation.

Precautions for planting green beans.

1.Planting and replanting.

Before planting green beans, it is necessary to do a good job of preparing the land and ploughing deeply, because this can improve the fertility of the soil and fundamentally eliminate the occurrence of pests and diseases. When planting green beans, pay attention to choosing seeds that have no wounds and no pests and diseases. When planting is successful, we should always pay attention to the growth of green beans, if there are dead seedlings or seedlings in poor growth state, it is necessary to pull out in time and then fill with healthy seedlings with the same growth rate.

2.Fertilizer and water management.

During the growth of green beans, water and fertilizer will have a great impact on their growth. When the green beans are in the seedling stage, they can be fertilized with well-rotted thin manure water or urea. When the green beans climb the seedlings, it is necessary to carry out timely top dressing, because this time period is the period when the amount of green beans fertilizer is the largest, the amount of green bean fertilization must be strictly controlled, about 2-3 tons of organic fertilizer per mu, and superphosphate and potassium sulfate can also be configured in the fertilizer.

3.Set up a frame to lead the vines.

Because green beans are creeping plants, it is necessary to build a frame in time when planting green beans, and generally choose to build a frame when the green beans grow to about 35 cm, and it is necessary to do a good job of leading vines in time, so that the plants of green beans can climb on the support, which can promote the growth of green beans.

4.Weeding treatment.

Weeding should be carried out on the 10th day after sowing, weeds will affect the growth and development of the plant, and can be diluted with a professional herbicide.

Hello, green beans are generally planted in spring and autumn, fertilize the land before planting, water and top dressing after sowing seedlings, protect flowers and fruits in the later stage, and pay attention to the prevention and control of pests and diseases. Green beans are planted from February to April. I hope my answer will help you, thank you!

Green beans, also known as kidney beans, kidney lentils, April beans, etc., are annual herbaceous plants. It is called Qingming beans in Quzhou, Zhejiang, and green beans in Sichuan and some central China, which is one of the common vegetables on the table.

It can be planted in spring and autumn, and it can be planted in spring when it rains in the valley.

Summary. In general, the row spacing is 30 and the plant spacing is 80 cm.

In general, the row spacing is 30 and the plant spacing is 80 cm.

If the row spacing is 70-80 cm, then the plant spacing is 50 cm.

The sowing specifications of green beans vary according to the type of variety, and the row spacing of dwarf varieties is generally 30 cm and 33 cm, with 6000 plants per mu. If it is sown in a hole, the distance between the holes is 30 cm, and each hole has 4 5 seeds. Creeping varieties generally have a row spacing of 65 cm, a hole spacing of 25 30 cm, and 3500 4500 holes per mu. For ease of management, large and small rows can be planted with a large row spacing of 70 cm and a small row spacing of 40 to 50 cm.

The sowing density should depend on the type of soil, soil fertility and the type of variety. The general principle is that loam soils are less dense, and poor sandy soils are denser and denser.

Green beans are a warm-season crop that is best grown at temperatures between 20°C and 28°C. In this temperature range, green beans grow the fastest and have the best quality. However, since the location and season of green beans will also affect the choice of growing temperature, growers need to adjust the temperature according to the actual situation.

If the plant is planted in spring or autumn, the temperature may drop somewhat, and the temperature can be increased by means of heat preservation and heating.

In addition to temperature, green beans also need proper humidity and light to grow. Green beans have high requirements for light and prefer full sunshine. In terms of humidity, green beans need the right amount of water to grow, but too much water can cause root rot and affect growth.

Therefore, growers need to take care to control moisture and maintain proper humidity.

When planting green beans, you also need to pay attention to choosing the right soil and fertilizing. Green beans prefer well-drained, fertile soil that can be improved before planting. In terms of fertilization, organic fertilizers can be used, which are applied at regular intervals to promote the growth of plants.

In short, as a crop in the warm season, green beans have certain requirements for growth temperature, light, humidity and other aspects. Growers need to adjust these factors according to the actual situation to ensure the growth and development of green beans. On this basis, it is also important to pay attention to the choice of soil and fertilization.

Only when the state is dispersed when all factors are taken into account can healthy, high-yielding green beans be grown.
