What soil and temperature do you need to grow green beans?

1.The climatic conditions of the winter cultivation and growth period of seasonal sowing green beans are opposite to those of spring cultivation, and the early stage is under the conditions of higher temperature and drought and the later stage is susceptible to low temperature, therefore, the cultivation management is different from that of spring green beans, and mastering timely sowing and ensuring the whole seedling is the key to obtain high yield. In recent years, the winter climate in Huizhou is warm, and the cultivation of green beans in winter can be marketed before the Spring Festival to early spring, and the economic and social benefits are more significant.

Reasonable dense planting is the key to high yield due to high temperature and rapid growth in the early stage of cultivation, and gradually lower temperature and poor development of side branches in the later stage. As far as the Huizhou area is concerned, it is generally good to plant two rows with a width of rice (with a ditch), with a hole distance of 10 20 cm, and 3 plants per hole.

Field management: After sowing green beans in winter, the field management should highlight the word "early", early water management, early fertilization, and early control of diseases and insects. The temperature at the seedling stage is high, the evaporation is strong, it should be watered and moisturized in a timely manner, and the soil should be drained and loosened after rain, so as to maintain good soil aeration performance, promote the rapid growth of plants, form a strong plant type in a short period of time, and flower and set pods as soon as possible. When pumping vines, fertilize the hole next to the plant, watering after the bracket, control the watering during the flowering period, water and top dressing after the pod, and apply a small amount of nitrogen fertilizer after the rain, which can alleviate waterlogging and prevent yellowing of the plant.

2.Green beans like warmth and are not resistant to heat or frost. The suitable temperature for seed germination is 20 to 25 degrees Celsius, and it is not easy to germinate below 8 degrees Celsius and above 35 degrees Celsius, so sowing green beans requires a stable ground temperature of 10 degrees Celsius; The suitable temperature for the growth of green bean seedlings is 18 to 20 degrees Celsius, and the growth stops below 13 degrees Celsius. The suitable temperature during the flowering period is 18 to 25 degrees Celsius, and it does not bear fruit below 15 degrees Celsius but above 28 degrees Celsius, and a large number of flowers fall off.

Note that green beans need an accumulated temperature of more than 700 to 800 degrees Celsius from sowing to flowering, below which the green beans will not bear fruit even if they bloom, so early spring cultivation must not be sown too early.

3.The soil requirements are not strict, but continuous cropping is avoided, the requirements for soil nutrients are not high, more potassium and nitrogen are needed, and less phosphorus is needed, but phosphorus has a great impact on the yield, and phosphorus fertilizer must be applied to plant green beans.

Green beans 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.

Green beans are most suitable for cultivation in deep, soft, humus-rich, well-drained soil caves, and in sandy loam, loam and general clay soils.

can grow, but it should not be cultivated in low wetlands and heavy clay soils. The suitable soil pH value is 6-7, which should neither be too acidic nor too alkaline.

Green beans love temperature and are not resistant to heat or frost. The suitable temperature for seed germination is 20 to 25 degrees Celsius, and it is easy to germinate below 8 degrees Celsius and above 35 degrees Celsius, so the ground temperature for sowing green beans is required to be above 10 degrees Celsius; The suitable temperature for seedling growth is 18 to 20 degrees Celsius, and the growth stops below 13 degrees Celsius; The suitable temperature for flowering is 18 to 25 degrees Celsius, and it will not bear fruit below 15 degrees Celsius and above 28 degrees Celsius. It is worth noting that green beans require an accumulated temperature of more than 700 to 800 degrees Celsius from sowing to flowering, below which green beans will not bear fruit even if they bloom.

Green beans like to grow in the season with higher temperatures, and their optimal temperature is 20-30 °C, and the maximum temperature can reach 35 °C in summer.

The minimum temperature in winter shall not be lower than 4-5 °C, if the temperature is too low, it will cause leaf wilting and cause root rot and other symptoms. and.

In addition, green beans have low rainfall requirements, and the average rainfall per mu is 800-900mm to meet their growth requirements, but when the temperature is too high or too low, it is still necessary to cooperate with appropriate irrigation methods to maintain the moisture of the soil and ensure the normal growth of green beans.

Green beans will also encounter ecological factors other than temperature and rainfall, such as sunshine, soil type, fertilization methods, etc., which will affect the normal growth of green beans, so when planting, it should be considered to ensure its effective growth and development.

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.
