What are the cultivation techniques of sweet peas, and how to manage sweet peas?

Sweet peas should not be replanted with other leguminous crops, and it is advisable to choose farmland that is rich, loose and easy to irrigate, medium to high fertilizer efficiency, and has not been planted with leguminous crops for 2 years.

The moisture surface is deeply cultivated and raked, and 2000kg of organic fertilizer, 30kg of phosphorus and potassium fertilizer, and 10kg of potassium fertilizer are applied per mu.

Generally, it is advisable to plant from mid to late October to early to mid November. You can choose to use **, row spacing 30cm, hole spacing 15 cm, 2 3 seeds per fine sowing, 4 kg of seeds per mu, 2 3cm of soil filling after sowing.

Check the seedlings immediately after germination, avoid the soil layer is too wet, the seedling fertilizer is dominated by fertilizer, and water once in 5 6 days after the seedlings, pay attention not to drench in the bean heart. When the seedling height is 30 cm, the integration of soil hoeing and loosening soil to protect the seedling, 10kg of compound fertilizer per mu at the flowering and poding stage, and ensure that the soil is moist, and when the field is drought, it can be irrigated "Shangshan Shui", rapid irrigation and rapid drainage.

When bacterial wilt occurs, 70% imported methyl tobuzin 800 times liquid sprayer is used per mu; To control leaf miner flies, you can use Lesben 1000 times liquid sprayer every 1 week after the seedlings are full; To prevent and control seedling damage, you can use a 45ml water sprayer before sowing seedlings. When the temperature is within -3, it is very easy to freeze and fall the seedlings, and the broken grass straw or chaff is used to cover the heat insulation.

Under normal circumstances, it can be effectively carried out in rotation, which will essentially reduce the occurrence of pests and diseases, but if pests and diseases occur, or if the intervention of drugs should be carried out as soon as possible, the prevention and control of pests and diseases will further increase and cause extremely poor damage to the production.

Cultivation techniques. When the young plant is about 557cm long, the mu can be used with thinner farmhouse fertilizer plus compound fertilizer 5-seedlings. The seedling height of 50-35cm should be set up to facilitate the release of vines.

After being put on the shelf, it can be combined with soil hoeing, and 60kg of compound fertilizer can be applied to 1 mu during the flowering and podding period. In order to increase the number of pods and improve the quality, during this time, the insects can be fused to carry out extra-root topdressing of trace element fertilizer, by spraying the leaves with 250 times potassium dihydrogen phosphate aqueous solution in the afternoon on a sunny day, and spraying once with 500 times the borax solution after 1 week.

Choose neutral soil, plant in early spring, choose a wide furrow and high ridge planting method, and require loose and fertile planting. Watering, fertilizing, catching insects, weeding, and paying attention to not stagnant water in a timely manner.

Be sure to clean up the stagnant water, then be sure to pay attention to the time of sunlight, then ventilate more, pay attention to reasonable density, spray pesticides, and prevent insect pests. The temperature should be kept between 15 and 20, and the fertilizer can be farmed with farmyard fertilizer, and the row spacing should be kept at about 40 cm when planting.

Pay attention to the soil and fertilizer conditions, you must make agricultural fertilizer, at least about kilograms, suitable sowing methods, pay attention to water and fertilizer management, pay attention to field management.

Be sure to choose loose and fertile soil, supplement organic fertilizer in time, and also pay attention to the way of sowing and the environment when sowing. It is best to keep the outside temperature constant at 18 degrees.

It is necessary to pay attention to the situation of soil and fertilizer, be sure to use farmhouse fertilizer, at least about 2000 kg, choose the appropriate sowing method, pay attention to water and fertilizer management, and pay attention to field management.

It is necessary to pay attention to the planting process of sweet peas, but also to the way of management, but also to pay attention to management skills, but also to pay attention to water and fertilizer management, but also to pay attention to temperature management. Be sure to pay attention to the state of the plants when managing them.

Sweet and crisp peas, is mainly edible tender pods, alias is soft pod peas, it is a kind of peas, the key management point is the seed treatment and fertilizer and water management during planting, generally speaking, it is necessary to water and fertilize frequently.

1. The planting time of sweet and crunchy peas

In the case of overwintering peas, they are generally sown from late October to mid-November, overwintered in the open field, and harvested in April and May of the following year. It can also be sown in spring, in the middle and lower reaches of the Yangtze River, from late February to early March, when the heat arrives. In the Northeast, spring sowing and summer harvest are all sown, and the sowing time is in April and May.

Peas are harvested in 6 months for winter sowing and 3 to 4 months for spring sowing. The soil is required to be well-drained sandy loam soil, and the bottom fertilizer is well-rotted organic fertilizer and cake fertilizer, which should be mixed evenly with the soil after being dispersed. For the water requirements, a small amount of water should be watered before the peas bloom, and the amount of watering should be slightly increased when the pods are set, and the soil should be kept moist, and the watering should be reduced after the pods.

Because peas grow slowly in the seedling stage, it can be intercropped with other vegetables or intercropped, usually, the time required for pea germination is 10 days, its seedling stage is 10 25 days, and the vine extraction period is 25 to 30 days. Inside the pea's flowering pods, its stems will continue to grow. The young shoots can be picked and used to make soups or stir-fried foods.

2. Planting and management techniques of sweet and crisp peas.

1. Three steps of pea sowing

Before planting, the pea seeds should be selected with 40% salt water, and the seeds that float on them, are not full, or are infested.

Pay attention to keep the soil moist and drench it once a day after the seedlings emerge.

2. Field management after pea emergence

3 4 days after the emergence of seedlings, it is necessary to apply the decayed human fecal water once in the past.

When the pea seedlings are about 20 cm high, top dressing should be done again, this time the concentration should be slightly higher. When the pea plant is extracted, it can be eaten according to its growth.

After the peas flower, it is necessary to apply organic fertilizer 1 more time.

After the peas bear fruit, a small amount of phosphate fertilizer and potassium fertilizer should be applied, and then the tender pods can be eaten. When the pea pods are full, the tender beans can be peeled.

Pea planting is actually relatively simple, it is one of the most common crops in the countryside, and the longest time from sowing to maturity is only about 1 and a half months, as long as you pay attention to water and fertilizer management after planting, you will generally achieve a good harvest.

<> need to grow sweet and crunchy peas in sandy or clayey soils with strong drainage capacity and a pH value in between; When choosing sweet and crisp pea varieties, it is also necessary to choose pea varieties with high yield, good quality and strong disease resistance, such as Changshouren and Yunpea 18; When the seedlings have grown to 3-4 leaves, urea is used to fertilize them.

1. Planting and management of sweet and crunchy peas

1. Planting techniques for sweet and crisp peas.

1) Land selection: To plant sweet and crunchy peas, you can choose sandy soil or clay soil with a pH value between them, and the soil drainage capacity should also be strong.

2) Varieties: You can choose pea varieties with high yield, good quality and strong disease resistance, such as Changshou Ren and Yun Pea 18.

3) Fertilization: When the seedlings grow to 3-4 leaves, the seedlings need to be fertilized with urea. In the subsequent growth process of seedlings, it is necessary to apply urea fertilizer 3-4 times in combination with the actual situation of the soil.

2. How to manage sweet and crunchy peas.

1) Water management: After sowing, if there is a rainy season, the buried ditch should be cleaned up in time and the stagnant water should be removed to prevent the occurrence of rotten seeds and roots. If there is a drought and little rain, it is necessary to water the pea seedlings every 3-5 days.

2) Field management: When managing sweet and crunchy peas, stagnant water and flood irrigation should be prevented; Carbendazim wettable powder, mancozeb wettable powder, dichloride emulsifiable concentrate and other agents can also be used to control pests and diseases.

2. When is the right time to plant sweet and crunchy peas?

1. It is suitable for planting sweet and crunchy peas.

Generally, sweet and crunchy peas can be planted from early September to early November, and the time to plant sweet and crunchy peas should not be too early or too late.

2. How to eat sweet and crisp peas.

1) Add garlic paste to the pot and stir-fry until fragrant, then put the washed sweet and crisp peas into the pot and stir-fry quickly and add flavor to taste, until the peas change color, and then you can take them out of the pot.

2) You can put the sweet and crisp peas in boiling water, boil for about 1 minute, then remove them and put them on a plate, and eat them directly with various sauces.

Peas are prone to grass shortage at the seedling stage, and must be cultivated and weeded 2 3 times. Creeping peas must be erected when the plant height is about 30 cm, otherwise the stems and vines creeping on the ground, which is not only inconvenient for field management and harvesting, but also the lower stems and leaves are easy to rot and cause diseases. Pea fertilization should be based on basal fertilizer.

In addition to the application of compost and manure, more phosphorus and potassium fertilizers, such as plant ash and bone meal, should be applied. If you can use rhizobia to dress seeds when sowing, the effect is better. Peas are poor drought tolerant and should be irrigated to keep the soil moist during the growing period.

In the event of drought after sowing, it is necessary to irrigate quickly to facilitate seed germination and emergence. It requires more water during the flowering and podding stage.

1) Land preparation: northern peas are sown in spring, after the previous harvest, stubble weeding, deep turning, full organic fertilizer, irrigation in winter, and rake to protect moisture after thawing the soil surface in the following year. In areas with more rain in the south, ditches should be opened to make drainage and irrigation smooth.

2) Sowing: early spring sowing in the north, sowing date 3-4 months; The winter sowing period in the south is 10 to 12 months, and the autumn sowing period is 8 to September. Under the general soil fertility level, 751,050,000 peas per hectare; Plots of semi-leafless peas with medium fertility or above, 1.2 million 2 million plants per hectare.

3) Water and fertilizer management: based on base fertilizer, in addition to compost and manure, more phosphorus and potassium fertilizers should be applied, such as plant ash, bone meal, etc. Diammonium phosphate can also be applied as basal fertilizer and seed fertilizer.

Spraying boron, manganese, molybdenum and other trace element fertilizers at the flowering and podding stage had a significant effect on increasing yield. In the northern spring sowing area, peas should be watered 2 3 times during the flowering and pod-setting stage, and once every 10 days or so. In the rainy areas in the south, deep ditches and high furrows should be paid, and attention should be paid to drainage.

4) Cultivating and weeding: the first tillage when the plant height is 5 7 cm, the second tillage when the plant height is 15 20 cm, and the third time can be flexibly mastered according to the growth of peas. Weeds should be pulled out in time in the later stages of growth.

The field management of pea cultivation should first grasp the sowing time, the sowing time is different according to the climate, and the peas cultivated in the winter are generally sown from late October to mid-November.

To keep the soil loose, the soil water absorption and permeability should be good, to add some compound fertilizer and phosphorus fertilizer and nitrogen fertilizer appropriately, to maintain sufficient sunlight, the temperature should generally be kept above 20 degrees, generally in the morning and evening can be watered, but do not cause water accumulation, so that pea seedlings can grow.

In dry weather, when the soil is dry and there is no water, it is necessary to water in time to prevent the pea plants from dying due to lack of water, especially in the flowering and pod-setting period of peas, the water demand is very large, if the water is insufficient, the impact on yield and quality is very large. However, if it is rainy or rainy, then we should dredge the ditch in the field in time and drain it, and at the same time observe that the field is a pothole area and try to drain the stagnant water in the field.

First of all, the management of water and fertilizer should be strengthened, and it should also be watered and fertilized in a timely manner, and insect pests should be removed regularly, and some pesticides should also be sprayed in time, and it should also ensure that the light is sufficient and the temperature is appropriate, to ensure the fertility and permeability of the soil.

The first step is to prepare the land. The second step is to choose a good planting period, such as March to April every year, and then have very moist soil. The plant height is preferably between 5 cm and 7 cm.

If the seedling height is about 10 cm, it is best to water it in time, and it is necessary to top dressing in time, the last to three times a year. Be weeded frequently. And it has to have very good drainage and irrigation technology.

So that there will be no drought.

1. Cultivating loose soil

After the pea emerges to the plant before the ridge sealing, the soil should be cultivated in time 2 3 times, the depth of cultivation should be mastered first shallow and then deep, generally the seedling height of about 8 cm when the first tillage, the plant height of 15 20cm can be carried out the second tillage.

2. Top dressing

Pea seedlings such as thin seedlings yellow, in case of rainfall should be timely topdressing, generally can apply urea 5 8 kg per mu as seedling topdressing. In order to improve the yield, foliar sprays of phosphorus and potassium fertilizer should be applied 2 to 3 times at the flowering and podding stage.

3. Pest control

Peas often develop rust, powdery mildew, etc. during the growth period. After the onset of the disease, the diseased leaves should be removed in time, the diseased plants should be uprooted, and the disease should be burned in a centralized manner. The occurrence of rust and powdery mildew can be prevented and controlled with 25% powder rust 2 000 3 000 times.

At the same time, it is often harmed by leaf miners, and can be sprayed with 80% dichlorvos 800 times to treat aphids and laiqing insects.

4. Harvest

The pea harvest period is mostly in June to August. Generally, when most of the stems, leaves and pods of pea plants turn yellow and the stems and tips are dry, they should be harvested in time. In order to prevent the fried pods from falling grains, the harvesting and transportation time should be carried out in the morning when the dew is not dry.

Pea fields should be flat and easy to drain, the soil should be rich in nutrients, sandy loam or clay, and the pH value should be slightly acidic or neutral. Before sowing, the land should be plowed to ensure the permeability and drainage of the soil.

Pea seeds should be selected without disease or sterilized before sowing, and then sown after air drying, so as to reduce the incidence of disease. Friends in the Yangtze River basin mostly sow seeds in autumn, and can also be sown after the beginning of spring.

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.
