If you want to grow peas in a greenhouse, how do you control the temperature?

Pea is a cold and long-day crop, and the varieties that are numb to light, cold-tolerant, early-maturing, and resistant to stress should be screened out for cultivation in all seasons. Its advantages are short growth time, large elasticity of the seeder, high yield and excellent quality. Improve the application of planting facilities such as plastic film greenhouses, greenhouses, and shade nets, and successfully realize the planting of peas in four seasons.

Peas can be grown in all seasons, so vegetable farmers can flexibly control the sowing time according to the stubble, season, etc., and determine the appropriate sowing date according to the needs of the time when the pods are on the market. Peas planted in the summer should pay more attention to the timely water**. This can not only meet the water requirements of plant growth and development, but also effectively reduce the surface temperature and promote normal growth.

In winter, peas planted in plastic greenhouses should be filled with plastic film in time, and the cold insulation work should be done well, and the cold protection materials should be temporarily covered before the arrival of strong cold snaps in the short term, so that the edamame pods can avoid the East China Sea. Due to the high temperature, fast growth, short growth period and small pods, summer cultivation can effectively reduce direct sunlight, reduce air temperature and ground temperature, improve soil moisture, promote individual plant growth and increase yield. Greenhouse planting peas should properly control fertilizer and water, reduce the temperature of coffee beans, convert vegetative growth into reproductive growth, ensure the reasonable distribution of photopolymers between vegetative growth and reproductive growth, and promote flowering and fruiting.

When planting peas, it is necessary to choose good seeds, if you choose *** seeds, the yield will also be higher.

This seed has a high germination rate, and the selected seed will germinate, soak it for about a day and then plant it. When we are on the seeds, the first thing we have to do is to water, sow the seeds, and cover the soil. Proper fertilization should be applied when planting peas, and fertilization should be applied before planting peas.

This is what people call a base fertilizer, which makes peas grow better, and proper watering after planting peas promotes pea germination. Different regions have different climatic conditions, and the planting time is also different. If peas are planted in the Yangtze River basin, they are usually planted when the winter is coming by quickly.

Autumn planting can be harvested, the temperature in the northern places is low, and the planting time is harvested in spring and summer, but in fact peas do not have strict requirements for light.

You can attach a film to the root of the pea to maintain the temperature, and the water vapor produced by the sun can also replenish the moisture.

Personally, I think that if you want to control the temperature, you can make a thermostat controller at this time, and only in this way can you achieve the purpose of controlling the temperature.

The right temperature should be chosen and kept around 50 to 55 degrees Celsius when growing in a greenhouse.

Indoor potted plants should be maintained in a sunny location, and the room should be ventilated to prevent growth or bud fall. For climbing varieties, a scaffold can be set up to determine the flowering period can be controlled by temperature regulation, the plants that bloom from December to February and March of the following year can be maintained in a medium greenhouse, and the plants that bloom in May of the following year can be transplanted to a cold room for wintering.

Peas can be said to be one of the hardy plants among the plants. Sweet peas can tolerate low temperatures of minus 5, and below minus 5, they grow poorly. Cultivated indoors, fragrant peas can be grown in the range of 5 to 20.

When the temperature is as high as 20 25, the plant growth gradually declines, and the peduncle becomes shorter. If the temperature is above 35 consecutively, the pea plant will die. Native to Sicily, Italy, the pea prefers warm winters and cool summers, sunny and humid air, and is most resistant to hot and dry winds.

There are about 130 species of the genus Sweet Pea, which are widely cultivated all over the world, such as dwarf varieties with erect stems, dwarf, dense plants and suitable for potted plants. According to the flower type, it can be divided into four types: flat petal, curly petal, wrinkled petal and double petal, and can be divided into three categories according to the opening of the flowering period: summer flower, winter flower and spring flower, and with the progress of breeding work, the cultivars continue to increase.

The sowing date of sweet pea varies according to the desired flowering period and variety, with early-flowering varieties being seeded in early August and early September, and late-flowering varieties being sown in January and February. The optimal germination temperature for the seeds of fragrant peas is 20 and germination takes about 13 days.

Sweet pea stalks and leaves can be used as livestock feed or green manure. The flower shape of the fragrant pea is unique, and a branch is slender and soft, which can be used as a winter and spring cut flower material to make flower baskets and garlands, and can also be potted and enjoyed indoors.

1. Soil: To plant peas, you need to prepare a sandy soil with loose soil, rich in humus and strong permeability.

2. Planting: Plant pea seeds directly into the soil, pour an appropriate amount of water, and keep enough water in the soil.

3. Light: Provide bright astigmatism every day to promote rapid rooting and germination.

After pea planting, the soil should be loosened several times to improve the ground temperature to promote root growth, the seedlings are robust, and the autumn sowing is cultivated, and the soil is cultivated once before wintering, and the soil is kept warm and anti-freezing in winter, and the soil is loosened and weeded in time after the beginning of spring to improve the ground temperature.

Before the pea flowering, water a small amount of water to chase the fast-acting nitrogen fertilizer to accelerate the growth of the plant, promote the division of technology, and then loosen the soil to protect moisture. When the stems begin to sit on the pods, the amount of watering is slightly increased, and phosphorus and potassium fertilizers are chased.

The hardy temperature of peas is between 0 and 10 degrees. When planting, we must choose high-quality varieties, choose fertile soil, spray pesticides regularly, remove insect pests in time, ensure sufficient light, and also need to do a good job of water and fertilizer, remove weeds in time, and do a good job of drainage and ventilation.

Generally, it is minus 10 degrees, to choose fertile soil, you can spread mulch, pay attention to density, you should do a good job of seed seedling, you can soak the seeds in hot water for about two days, and then you must strengthen management.

One to two degrees. When planting peas, prepare the pea seeds, then find a piece of soil and put the pea seeds in the soil so that they can be planted.

The spring-sown peas are harvested in early April and the seedlings are pulled in early JuneAutumn-sown peas are harvested from early October to mid-November, and there are two main sowing methods: sowing and strip sowing. Spreading involves spreading the pea seeds evenly on the built furrow and raking the seeds into the soil. Peanut stubble is used for planting in this place, no longer fertilized, after ploughing the land, according to the row spacing of 40 cm, 20 cm five to seven grains of ditching and sowing.

Cover with soil for three to five centimeters. The use of residual fertilizer in peanut fields will surely lead to a bumper harvest of beans. If the fertilization is too dense, the meandering beans are more than 60 centimeters high.

When it comes to pea planting time, it can be flexibly mastered according to the season or stubble, and of course, the appropriate sowing date for peas can also be determined according to the time and demand of pea tips or pea pods. Although it can be sown all year round, it is best to plant peas in autumn, and in our local area, peas are generally planted in April and May in the first half of the year, and harvested in September and October. Because peas prefer a cool climate, for peas that need to go over the summer, special attention needs to be paid to the impact of high temperature in summer on pea seedlings.

After sowing, we should check frequently, and if we find that the lack of seedlings is missing, we should replant them in time to ensure that the seedlings are early and the seedlings are full. When the pea seedlings are about 3 cm high, you can start thinning the seedlings, and you can leave 1-2 seedlings in each hole. Pea grows slowly at the seedling stage and is prone to grass shortage.

Pea planting time can not be too early, too early to grow grass seedlings longer, is not conducive to frost in the winter, grass seedlings are easy to frostbite, is not conducive to the spring of the year to continue to grow.

In the middle and lower reaches of the Yangtze River, sowing is generally from late February to early March, and in the northeast of China, it is generally sown in April and May. When the seedlings grow to 10cm after emergence, and when the pea seedlings grow to about 25cm, they should be cultivated and loosened once in the early flowering stage, and some foliar fertilizer and vegetable and fruit should be sprayed appropriately in the flowering and fruiting period, so as to improve the fruit setting rate, and do not water too much.

The sowing time of peas varies according to the latitude and longitude and altitude, the sowing in the north of the Yangtze River is in March and April in spring, the harvest is in July and August, and the sowing in the south of the Yangtze River is in September and November. The time for planting in the mountains at relatively high altitudes is in August. After sowing seedlings, you can loosen the soil shallowly at the roots, increase the ground temperature, promote the growth of the roots, sow peas in autumn before entering the winter, first carry out a soil cultivation to help it keep warm for winter, and then loosen the soil and weed in the spring rain season of the second year.

It is planted in late February or early March in the middle and lower reaches of the Yangtze River, April and May in the northeast, and is best planted in September in autumn, and the soil is loosened at the pea seedling stage after planting. Fertilization is carried out during the growth period, watering during the flowering period and clamping period, proper leaf thinning during the flowering period, and erection of pea seedlings when they grow to 30 cm.

Sowing seeds in the spring is best. Precautions: Do not water before seedlings emerge to prevent rotten seeds.

When the seedlings are about 500 cm long, the seedlings are lifted with 5 kg of thin human manure and compound fertilizer. When the seedlings are high, build a shelf and lead the vines to the shelf. Spray the fruit at the flowering and podding stage to promote fruit development.

<> peas generally take about 65-185 days from planting to maturity, and the maturity period of different varieties and different planting environments is very different. Peas do not have high requirements for soil, as long as the soil layer is deep and the degree of salinity is low, which helps the seedlings to survive and grow. Spring is a good time for pea planting, with late February to early March in the south and April-May in the north.

1. How long does it take for peas to mature from planting?

1. It takes about 65-185 days for peas to mature from planting, and the maturity period of peas is generally very different from different varieties and different planting environments. For example, it takes about 65-75 days from planting to maturity for early-maturing varieties, about 75-100 days from planting to maturity for medium-maturing varieties, and about 100-185 days from planting to maturity for late-maturing varieties.

2. The requirements of peas for soil are not very strict, as long as the soil layer is deep and the degree of salinity is low, such soil is conducive to the survival of seedlings and the growth of crops. When planting, you can choose the right pea variety according to your needs, and after sowing, you should loosen the soil to keep the soil soft and help the roots and seedlings grow. After the seedlings grow, we must remove the weeds in time and cannot compete with the seedlings for nutrients.

After the flowers bud, you can pour a small amount of water to help them grow in the later stage.

3. The planting time of peas is different, mainly divided into spring and autumn. Spring is very suitable for pea sowing, the southern region can choose from late February to early March, the northern region can choose from April to May, the spring growth period is relatively short, the harvest time will be earlier. Autumn sowing is also a good choice, suitable for early-maturing varieties, generally sown in early September, about before the cold spell arrives, and if you want to extend the growing season, you can cover it with plastic film.

Second, the suitable temperature for pea planting

1. Peas are semi-cold-tolerant crops, which prefer humid and humid climates and are not tolerant to heat and dryness. The cold tolerance of round-grained pea is better than that of wrinkled-grained seeds, and the initial temperature of seed germination is lower, the suitable temperature of round-grained seeds is 1-2 °C, and that of wrinkled seeds is 3-5 °C, and seed germination is slower at low temperatures. The seedlings of pea have strong cold tolerance, the suitable temperature at the seedling stage is 15-20 °C, the minimum temperature for flowering is 8-12 °C, the most suitable temperature for flowering and pod-setting is 15-18 °C, and the temperature at the pod maturity stage is 18-20 °C.

2. The drought resistance of peas is not as good as other vegetables such as beans and cowpeas, and the air humidity is about 75% during the growth period, and the relative moisture content of the soil is about 70%, so that the plants will grow strong and well. Peas are not tolerant to rain and waterlogging, and if it rains continuously during the growth period, it is easy to produce a variety of diseases. Peas need more water during the flowering and podding stage, and the relative humidity of the air should be 60%-80%, which is too high or too low will seriously affect the flowering and podding.

3. Pea has a wide range of adaptability to the soil, and the requirements for soil quality are not high, so it is suitable for sandy loam and loam soil with strong water retention, good aeration and rich humus, and the most suitable soil pH value is. For soils that are too acidic, lime can be added to the soil to improve the soil when planting.

Peas are a relatively common crop in rural areas, and they can be seen in rural areas because of their strong environmental adaptability. However, most of these are small-scale cultivations and do not have much skill. For those growers who specialize in growing peas, they are very scientific in each process, and can give full play to the advantages of technology, so that the pea yield can be increased in an all-round way, so as to bring more benefits to the growers.

Peas are normally planted around October. It is advisable to use sandy loam or clayey loam soil with good drainage pH, and peas should not be cropped continuously, and it is ideal to rotate with rice. The amount of seeds per mu of net seeds is about 5-7 kg, and the seeds should be disinfected, and each kilogram of seeds should be disinfected with 50% dixone wettable powder to prevent seedling rot.

Peas can be purebred or interseeded, purebred, open 2-4 meters, row spacing 40 cm, pond spacing 20 cm, tobacco bean interplanting, each soil planting two rows, pond spacing 20 cm. Sow 3-4 grains per hole, cover the seeds with farmhouse manure after sowing, and if the seedling rot is a serious plot, it is better to use soil and sand to cover it.

During the period from sowing to harvesting, the grass should be removed at least 2-3 times to promote the growth and absorption capacity of the roots and reduce the competitive pressure of the roots. If there is high temperature and little rain when the seedlings are not emerging, they should be watered in time to promote the speed of seed germination and emergence. Soil moisture should not be too high after emergence.

Prevent stagnant water from rotting the roots. However, if it rains continuously in rainy weather, the water should be discharged in time, and the humidity of the soil should be kept moderate, so as to prevent it from being too wet and too dry, causing flowers and fruits to fall.

The main diseases of peas are powdery mildew and downy mildew, and the seeds can be soaked in chemicals to sterilize before sowing. After sowing, carbendazim and methaloxin can be sprayed for prevention and control, if there is a diseased plant, it should be immediately uprooted and burned with other disease residues, reduce the source of infection and the source of germs, pay attention to the health and humidity temperature in the garden, and pull out weeds in time, improper temperature and humidity control is also one of the important reasons for the breeding of pathogens. Note that pea picking is mainly grain type fresh food, when the fresh food is full, the shell color is slightly light, you can pick and peel the grain in batches to market, and hold the bean vine with your left hand when harvesting to prevent the loss of bean plants.
