Pea is a legume with high nutritional value, what are the tips for pea pest management techniques?

Promote seed rotation, seed sterilization, seed dressing with 70% methyl tobuzin net weight of seeds, and plant after 48 to 96 hours in a closed type. Effectively fertilize sparse planting, improve the balance of supply and demand of chemical fertilizers, apply more phosphorus and potassium fertilizers, apply less basal fertilizers, and spray brassica on time to improve disease resistance.

When planting, pesticides must be sprayed in time, and the right medicine should be prescribed, and water and fertilize should also be selected, and phosphate and nitrogen fertilizers should be selected.

Pea disease and pest control requirements, in accordance with the "prevention first, comprehensive control combined" policy, give priority to the use of agronomic control, physical control, biological control, supplemented by chemical control of harmless control principles, the general season cultivation focus on the prevention and control of aphids and powdery mildew, off-season cultivation focus on the prevention and control of seedlings of bean fly and powdery mildew.

The sowing time is too early, the temperature is high, and the pea grows fast, so that the pea seedlings are prone to overgrowth, and the seedlings are slender. The sowing time is too late, and the temperature is getting lower and lower later, which has a certain impact on the germination of peas, although peas are vegetables that grow in winter, the sun is about 2 hours in the germination, soak in warm water for 7-8 hours to fully absorb the water and wash off the impurities, drench the water, wrap it in a wet towel and put it indoors, and control the temperature to 30 degrees Celsius.

About one, watering once a day in the morning and evening, 3-5 days to bud and sow seeds.

Peas are generally sown together with wheat and are planted around mid-September to October of the lunar calendar every year. In the second half of April and the beginning of May of the lunar calendar of the next year, it will be stored in the granary. And the land is not too wet.

This means that peas are usually the first crops planted in the spring. The earlier you plant, the earlier you can ripen and harvest, as it reduces the chance of damage from high temperatures during the rainy season. That is to say, if you miss the combination of the tongue, you will be damaged by various unfavorable phenomena, so planting peas in October of the ancient calendar is the best time.

Peas do not have strict soil requirements, and can be planted on well-drained sandy soil or newly cultivated land, and it is advisable to loosen neutral soil with high organic matter. Pea is a spring-sown annual or autumn-sown climbing herb.

It has never been good, so named for its stalk climbing. As a food for humans and animal feed, peas are now the fourth soybean crop in the world. After nine replanting, the temperature is high, there should be no problem, or it will affect the yield.

If you want to plant bean seedlings and beans to sell, the diseases of peas are mainly powdery mildew and downy mildew.

Before sowing, the seeds can be disinfected by dipping them in chemicals. Carbendazim can be used after sowing.

If there is a diseased plant, it should be immediately uprooted and burned with other diseased residues, and it should be rushed to seize time, use science and technology, and step on the greenhouse to maximize benefits.

The pests and diseases that should be paid attention to on pea tips are brown spot, downy mildew, powdery mildew, root rot, anthracnose, etc., which have a great impact on the growth of peas and must be prevented and controlled in time.

It should be noted that some aphids, leaf flies, mosquitoes, etc., these two pests and diseases are the most important, and this insect is also very scary, and these two pests and diseases spread very quickly, and there will be some germs, so you should pay attention.

Brown spot disease. Symptoms: Leaves, stems, and pods can all be damaged.

When the leaf is susceptible, it is light brown to black-brown at first, round, with obvious circumference, and then scattered small black spots with the size of a needle tip on the lesion; lesions on stems, brown to black-brown, spindle or oval, slightly concave, light in the middle, darker in the periphery; The lesions on the pod are round to irregularly shaped, **light brown, the edges are dark brown, and they expand inward and spread to the seeds, causing seeds to carry bacteria; The seed lesions are not obvious, and they are dirty yellow or gray-brown when the humidity is high. Brown spot disease is a common disease, and black spot disease, basal rot and brown spot disease are often mixed in production. It is prone to disease when the terrain is low-lying and waterlogged, the drainage is poor, and the soil water content is large; High temperature, high humidity, rain, and insufficient light are prone to disease.

For example, downy mildew, powdery mildew, brown spot, wilt, root rot, rust, anthracnose, leaf miner flies, aphids and so on.

Leaf miners, aphids, root rot, bud blight, rust, anthracnose, powdery mildew, brown spot, root rot, wilt and so on.

Hello, broad beans are generally planted in spring or autumn, spring is from mid to late March to early April, autumn is from early October to early November, timely planting is conducive to seedlings, seedlings even, seedlings strong, dry grain broad beans can not be planted in early autumn, in case broad beans suffer from low temperature frost damage during flowering. Second, broad bean planting method 1, select and sow to select full, high-yield, disease-free high-quality seeds, plough the land before sowing, so that the soil becomes soft, conducive to rhizome expansion and germination to form root nodules, and then use rhizobia inoculation to improve yield, you can choose to use the method of soil inoculation, in the plot where broad beans have been planted, dig about 50 kg of soil, and sprinkle it in the ditch when sowing. 2. Seedling management (1) in the seedling period to carefully observe the seedling situation, and according to the seedling situation to make the corresponding control methods, after sowing to cover the seeds with soil, cover with straw to keep warm, in the middle of the growth need to do a good job in pest control, the diseased plants and weeds are pulled out, and destroyed with fire.

3 bedrooms and 2 living rooms 100 million standard company dormitory existing house for urgent sale, the landlord returns to his hometown for development, the bottom price **, furniture can be sent to the advertising happiness in the details(2) It is necessary to spray pesticides in time for pest control, and control the water, tidy up the garden branches and seedlings, ensure the normal growth and development of the plant, have sufficient water in the later stage of growth, and reasonably control the density, which is conducive to maintaining the ventilation and light between the plants. 3. Top dressing and watering (1) After sowing, it should be watered in time, which is conducive to promoting the early emergence of seedlings, and gently compacting the soil to avoid lodging after growing up. (2) more trace elements can be applied at the pod-setting stage, which can reduce the loss of pods and improve the quality and yield of plants, and ensure the ventilation of the garden in the early stage of growth, and drain water in time when there is stagnant water, which is conducive to reducing the phenomenon of flower pods falling and bean grains shriveled.

4, cultivating pruning in the seedling bench early if there is a lack of seedlings, to replant in time, in the seedling period to frequent tillage weeding, the soil is thickened, to avoid lodging phenomenon, jujube finch in the flowering period before and after the need to pay attention to the seedling branching, if the broad bean branching is more difficult to pod, so it is necessary to prune the excess branches in time, to promote the trunk to absorb more nutrients, improve its fruiting rate, full rate. 5. Harvest broad beans in a timely manner can be harvested in batches, from bottom to top about 7 days can be harvested once, during which a small amount of mature seeds can be preserved, and when the leaves fall, prepare for laughter, pick the middle and lower part of the pods, and peel off the shell after drying them for preservation.

The fifth pea is in a harsh environment, what is its function.

5 beans in one pod. What about the rest of the peas? The function of this sentence in the text is:

1. Ask questions and make people think. Stimulate people's interest in reading. 2. Draw out the following and name the direction of writing.

What pests and diseases can occur when growing peas? How can it be prevented?

Peas are a common vegetable, very popular with people, and are basically grown in rural areas, but vegetables can be harmed by pests and diseases when they are planted. So what are the common pests and diseases when growing peas? Let's find out together.

Root rot. From small plants to adult plants, it can be sick, and it is most infected by firearms, mainly on firearms, mainly harming the roots and lower stems of plants, and the leaves of diseased plants begin to turn yellow first, and gradually develop to the median position, causing the whole plant to wither. The roots also turn black-brown or earthy red, and the nodules and root hairs are significantly reduced.

The disease is mainly spread by the fungus through the soil, diseased residues and seeds, through the invasion of seeds and roots, and the disease is usually severe in drought years. Prevention method: It can be prevented by mixing chemicals or mixing soil, and carbendazim and chlorothalonil root prevention can be used when the disease occurs.

Brown spot disease. Mainly damage leaves, stems, pods, when the leaves are sick, light purple spots appear, spots spread rapidly in high temperature and high humidity environment, covering the whole leaf, diseased leaves wither and die, and some appear brown irregular shape of the ring pattern. Mainly because the fungus overwinters in the seeds, the wind and rain spread, the seeds are scattered too early or are affected by low temperature and cold, the soil is viscous, the humidity is high, and the nitrogen fertilizer is sandy, and Wangzhuang may also cause this disease.

Prevention method: Implement non-leguminous vegetables and 2-3 crop rotations, and at the same time require seed disinfection, pickled buds, induce production, and proper dense planting when sowing. In the early stage of the disease, it can be continuously sprayed with benzomyl, nail vomiting, and leukophanium blue control, once a week, 2 3 times.

Powdery mildew. Light yellow spots appear in the early stage of the disease, gradually expand to irregularly shaped pink spots, and in severe cases, they are covered with white powder on both sides of the leaves, and eventually wilt and die, and later the pink spots turn gray and cut into many small black umbrella-like particles. Prevention method:

At the beginning of the disease, spray powdered cyanoxin, carbendazim prophylaxis**, spray 2 3 times continuously every 10 20 days.

Broad bean. Commonly known as arch leaf insects, leaf maggots and other polyphagous pests, more than 100 kinds of hosts, mainly harmful to vegetables, celery, cabbage, radish, etc. Prevention method:

When vegetables are harvested, the remaining fallen leaves and weeds in the field can be removed in time, buried less or buried deeply, pest reduction technology, and 31% abiparimine and 5% abibimycosm oil can be used for prevention. Introduce the prevention methods of common pea pests and diseases. I hope it will be helpful to everyone.

Powdery mildew. It is caused by the infection of pea powdery mildew fungus, mainly in leaves, stems and vines, and mostly starts in leaves. At the beginning of the leaf surface, small white powdery yellowish dots appear, and then expand into irregular pink spots, which are connected with each other, and the surface of the diseased part is covered with white powder, and later spread to the stem.

Brown streak, agricultural control: can be rotated with non-leguminous crops for more than 3 years, and seeds, soaked in warm water for 4-5 hours, and then moved into 55 warm water for 5 minutes, put in cold water to cool, dry and sowing. Appropriate dense planting, increase potassium fertilizer.

The pests and diseases that will occur when planting peas are, black loon fly, brown spot, root rot, powdery mildew, leaf miner fly, ** method, you can spray the drug, bury the medicine in the soil, and disinfect the seeds before planting.

As the saying goes, whether the crop grows well or not, the bottom fertilizer is the key, so when planting peas, the bottom fertilizer should also be applied to the bottom fertilizer, the bottom fertilizer is mainly based on the rotten farmhouse fertilizer, if you can use rhizobia to dress the seeds when sowing, the effect is better, the pea rhizobia has the effect of nitrogen fixation, and after the pea seedlings are unearthed, because of various reasons, the pea seedlings are not neat, and when there is a shortage of monopoly seedlings, it is necessary to replant in time to ensure the number of basic seedlings per mu, and stabilize the yield. Peas are afraid of heavy stubble, generally to 2 3 years of rotation, deep ploughing when the mu is about 1000 kg of rotting organic fertilizer, 50 kg of superphosphate, 100 kg of plant ash, or directly with 50 kg of ternary compound fertilizer, to make a rice wide flat furrow.

Sow. The sowing time of peas is generally about 10 days later than the normal sowing time of wheat, and the row spacing is slightly larger than that of wheat, generally about 25 cm, the plant spacing is 3-5 cm, and the sowing width is 3-6 cm. The large pods have No. 1 and No. 8, the small pods have Taichung No. 11 and No. 13, and the medium pods have them, while the sweet and crisp beans are selected from varieties such as Qizhen 76 or Cuizhu.

The second is the grain eating type, which is generally selected as the No. 4, No. 5, No. 6 and pearl green, which is most suitable for mountain planting.

Pea field management is also very simple, as long as the land is well prepared, fertilizerd, watered, and weeds, pests and diseases are well controlled, you can have a good yield. In the process of planting, as long as the key points are done, you can save a lot of manpowerThe bowl bean does not have high requirements for the soil, all kinds of soil can be cultivated, the drainage should be good, the soil with sufficient phosphorus fertilizer is the most ideal, if the fertilizer is insufficient, the lower part of the branch is few, and it is easy to wither.

2.Before the budding of the plant, digging is mainly used to promote the deep growth of the root system, and lay a good foundation for absorbing a large amount of fertilizer and water during the full fruiting period,.。

Peas cannot be planted in one plot for a long time, soil tilling work is carried out before planting. Apply enough manure to the plough so that you can provide enough water for the peas to grow.
