What are the consequences of peanuts being in cold soil for a long time after sowing?

Especially when the weather suddenly turns cold and hot, you must pay attention to peanuts this spring. Remind everyone that there is a good chance of encountering the cold of late spring. In particular, high-quality, safe insecticides and fungicides should be used for seed coatings, protective fungicidal seed coatings should be used, and azole fungicides should not be used as much as possible.

In the event of spring cold, the fungicidal seed coating has the effect of protecting the seeds, the seedlings are fast, the seedlings are good, and the rot is prevented. Seeds are of poor quality, stored incorrectly, or have been stored for too long.

Geothermal lowland, soil viscosity, texture differences, high soil moisture content, long seed appearance time, and poor cessation all affect the water absorption of seeds, and the seedlings become weaker. The seeds are not neat and uneven in size. The application of organic manure that is not fully mature or the fertilizer concentration is too high, resulting in fertilizer loss.

Sowing is not fine or shallow, making the buds uneven or no bud furrows. For many years of continuous cropping, no stubble, serious seedling diseases (root rot, stem base disease), lack of seedling ends.

Low temperature time is long, germination, germination, decay after sowing the average daily temperature is less than 13 for more than 3 days, with the rainy season soil moisture excessive, decay will occur. The average daily temperature is below 10 for more than 5 days, and the rainy season and the soil are moist, which can cause serious seed rot. The average daily temperature is 13 for more than 5 days, with no precipitation or at least some decay in precipitation.

It is best to listen to the weather forecast before planting. Can the low temperature, rainfall, and ground temperature of 5 cm deep soil stabilize at 15 in the next 5 days?

The most suitable temperature for peanuts is 23 degrees Celsius for early maturing peanuts and 26 to 30 degrees Celsius for medium and late maturing peanuts. The higher the temperature, the faster peanuts appear. For example, the average daily temperature of most varieties is between 14 degrees Celsius and about 20 days for germination, and the average daily temperature increases by 1 degree Celsius, and the appearance time is shortened by about a day.

The temperature is too low, and the three are dangerous. In most areas, it is recommended to have some light rain in the past two days after spring sowing (after spring sowing, and many farmers want to plant peanuts, which is absolutely not possible!). Peanuts are a rarefied crop, so when the temperature is below 13, the seeds will not germinate.

The north (Guyu 3354 into the river) is the best time for sowing.

After the rainfall, the temperature rises to about 20, but the surface is damp, the water evaporates and absorbs heat, the ground temperature is relatively low, the peanuts do not germinate, and the temperature is low, so it is useless to plant half a month in advance. Before the weather change before the rain, the temperature is suddenly high and low, and when it encounters low temperature and high humidity, it is easy to have moldy and rotten seeds, so the emergence rate of peanuts is low, so early sowing will not increase the yield, but reduce the production.

Peanut sowing in the low temperature soil for a long time, in April there is often a spring cold occurrence, rain increases, after cooling, peanut kernel in the soil for a longer time, seedling emergence slowdown, then the probability of rotten seeds will increase, thereby affecting the seedling emergence rate, can not achieve the purpose of increasing yield.

The temperature is too low and easy to rot seeds, unable to emerge, resulting in a reduction in peanut yield, should be improved in this way, the appropriate temperature of the soil is 10cm at least 15 when sowing is the best. The south should be sown early, the north should be sown late, and the southern Lunan area is the most suitable around May 1 of the Gregorian calendar.

In low-temperature soils, with the excessive soil moisture in the rainy season, seed mold and rot are prone to occur, and the longer the seed decay will be, the more serious the seed rot will be, so the peanut emergence rate will be reduced.

When the average temperature on the sowing day is lower than 13, more than 3 consecutive days, accompanied by rain, and excessive soil moisture, seed rot will occur;

If the average daily temperature is lower than 10, more than 5 consecutive days, accompanied by rain, the soil is too wet, it will cause serious seed rot;

Excessive rain is also extremely unfavorable for peanut seedlings, rain will cause soil subsidence or compaction, which will affect the depth of seeds and germination efficiency. Fertilization at the seedling stage is an important remedy, and watering diluted urea fertilizer can promote seedling growth. Peanuts are more drought-tolerant crops, and too much water is not good.

It is easy to have long stems and vines, and the pods are sparse, but they are not affected by drought. Therefore, water and fertilizer management is particularly important. There is no way to do so.

It's a big deal. To deal with the matter afterwards, I help the unseeded peanuts to loosen the ground with a hand-basket during the emergence of seedlings.

Peanuts have just been sown and encountered heavy rain, generally have little impact on peanuts, but if peanuts are sown too deeply, soil acidification and compaction are serious, it also has an impact on peanuts unearthed, although such peanuts can be unearthed, but the seedlings are weak and the yield is low. As long as the excess rainwater is discharged out of the ditch in time, do not let the seedlings soak in the rainwater for a long time! Otherwise, after a long time, you will either drown, rotten roots, and there will be a lot of pests and diseases!

No, the impact is not big, it will rain in the next day or two, but it will not be good if it rains for a long time! It depends on the situation of your land. If you plant a paddy field, the kind that is very waterlogged, then it may have an impact on the germination of peanuts and cause rotten seeds.

I have planted peanuts many times, just planted peanuts immediately rained, as long as it is not soaked for a long time, that is, soaked in water for more than three days, even if the weather drops, it will not affect the peanut germination.

<> the impact is not big, you have to see if the peanuts have been washed out of the soil by the rain, and the water in the field is drained so that the rain does not soak the peanuts for too long and the peanuts are planted. The temperature is very low. Sudden heavy rain will have a certain impact on the emergence rate of peanuts.

Because he has to do with the climate. The higher the temperature, the faster the emergence of seedlings. At the end of the month, the germination rate of seedlings will be lower.

The peanuts that have just been planted have rained and the cold wave has come, can they still sprout? It had snowed the night before, and in some places the wheat seedlings had been crushed by the snow. Until now, the rain and snow particles are still falling,:

It has an effect on the germination of sown peanuts.

Rainfall will cause the soil to collapse after planting, reducing the depth of growth and the chance of survival of peanut seeds, but it can be effectively remedied by fertilizing the seedlings at the seedling stage to make the peanut seedlings thrive.

When peanuts are watered or rained after sowing, the emergence rate or seedling growth is not as high as that of watering before sowing. Because the current temperature is not too high, it can meet the minimum temperature requirements for peanut seedling, and after peanut sowing, it rains, and the temperature of the soil is reduced, which is not conducive to seedling emergence. In addition, there is a lot of water in the soil, which will squeeze out the oxygen in the soil, and although the seeds can absorb water and expand, it is difficult for them to germinate without oxygen.

Of course, if it is a sandy soil, it has a relatively high air permeability, so it is less affected. However, for plots with heavy soil and poor land preparation, the emergence of peanut seedlings will be greatly affected.

Peanuts are actually good for the rooting and growth of peanuts when they encounter rainy days just after sowing, saving their own labor to water, but they should be careful not to soak in water for a long time.

If it rains just after the peanuts are planted, the rain may cause the peanuts to fail to come out or be flooded by the rain, and if the rain is too heavy, the peanuts will also be spoiled by the rain. In this way, it has an impact on the emergence of peanuts.

Drought at the early stage of peanut seedlings can promote the growth of main stems. In the late drought, the growth of the main stem was stunted, and the leaf emergence rate accelerated with the extension of drought time. The growth and defoliation rate of the main stem were consistent during the drought at the pod-setting stage, and the growth amount and growth rate decreased with the extension of drought time. Although Shandong, as the main producing area in China, is also facing a severe drought this year, it is believed that the yield will not have much impact due to the relatively complete agricultural infrastructure and the wide application of water-saving planting in peanut planting, coupled with the fact that peanuts are a relatively drought-tolerant crop.

Planting density and climate. Climatic conditions have a great impact on the growth and development of peanuts, and when determining the planting density of peanuts, it is necessary to consider the general grasp of high temperature and humidity areas should not be too dense, and low temperature and drought areas or high temperature and arid areas should be properly densely planted. You can cover the mulch for about 10 days, and then take it away when the buds have completely grown.

Therefore, if you want to have a high yield of peanuts, the distance between each plant is very important, and the appropriate row spacing and spacing can make peanuts have space to grow, and the seedlings will grow tall and thick, and the fruits will be large.

Peanuts are now planted or planted by machines. The row spacing is generally between 25-50cm, and the ridge width is generally between 50-70cm. The plant spacing is generally about 15cm!

It is conducive to the formation of peanut oil, so that the peanut grains are full, the quality is good and the yield is high, but the sandy soil is easy to cause the loss of water and fertilizer, and the fertilizer and watering mold should pay attention to a small amount of water, but the peanut is not resistant to salt and alkali, and the planting in the saline-alkali land is germination and easy to die seedlings, and the growing plants are short, and the amount of Dan production is low.

The row spacing of single-grain strip seeding is the same as that of double-grain strip seeding, and the plant spacing is centimeter. In the north, the row spacing of single-row ridges is 35-45 cm, the plant spacing is 13-15 cm, and the double-row ridge species are 40-45 cm in large rows, 25-30 cm in small rows, and 15-18 cm in plant spacing. It can also reduce the occurrence of many unnecessary diseases. It is best to sow at a density of about 30 centimeters between rows and about 20 centimeters between plants, which can not only make full use of the land, but also increase the fruiting rate, thereby increasing the yield of peanuts.

I don't think it will have a big impact, because peanuts are a dry crop, and the more the sun is on, the stronger its growth ability will be, and the higher the yield, but the rainy season will reduce the yield.

Generally speaking, the impact is not very large, because peanuts are not very water-hungry plants, but if there is a long-term lack of water, it will definitely affect the future development, and it is not very positive.

In the case of drought in the land, it will have some very negative effects on the peanuts planted, which will directly cause the peanut to be difficult to grow and affect its fruiting rate.

1. Southern peanuts can be sown twice a year.

1) Spring is sown around the third month of the lunar calendar, and spring peanuts bear more fruit than autumn peanuts, and the fruits are full.

2) Autumn peanut sowing period should be in early August at a low altitude, and sown in late July at a higher altitude.

2. In the cold and alpine areas with short frost-free periods in the north, multi-grain varieties are mainly planted; In the northern peanut area, common varieties are mostly planted. The suitable sowing period for large peanut and flower production areas in the north is mostly from late April to early May.

3. Peanut is a temperature-loving crop, so the temperature must be suitable, and the most suitable stability for peanut sowing is about 12, and the most suitable temperature for flowering is 23-28, and the lowest temperature is 19.

Extended Links. The economic significance of peanut production.

Peanut (Arachis hypogaeal.).It occupies an important position in Liaoning's agricultural production and people's lives, and by 2010 the planting area has reached 10,000 mu, ranking behind corn and rice, and is the third largest crop in Liaoning Province, ranking fourth in the national peanut area, accounting for 10,000 mu of the total peanut area in the country, and is the preferred crop for drought resistance and disaster avoidance. Peanuts are rich in fat and protein, and are edible vegetable oil, food, protein**, and are also a bulk export agricultural product in Liaoning Province.

Peanuts have a wide range of uses and play a pivotal role in the development of the national economy.

1. Peanuts are the main edible vegetable oil for human beings**.

Peanut kernel has high oil content, crude fat content is about it, and the oil yield is about it.

2. Peanuts are the main plant protein for humans**.

Peanuts are protein-rich crops with a protein content of seeds. According to the statistics of the Food and Agriculture Organization of the United Nations (FAO), the world's peanut protein production is second only to soybeans and cottonseeds, ranking third, reaching 10,000 tons a year, accounting for the world's plant protein resources.

3. Peanuts are an important raw material for the food and pharmaceutical industries.

Peanut kernels have high nutritional value and special aroma, taste and chewable texture, which is a good raw material for the food industry. Foods made directly from peanuts include roasted peanuts (roasted peanuts, roasted peanuts, spiced peanuts, salted peanuts, etc.), fried peanut kernels, peanut candy, peanut cakes, peanut butter, etc. There are hundreds of kinds of peanut candy made from peanuts and peanut butter as raw materials or additives.

Such as peanut nougat, peanut plate sugar, peanut crisp candy, cream peanut candy, peanut fruit, peanut crisp, etc. Peanut oil can be used to make margarine, shortening, salad oil, blended oil. It can also be used to make matrices for soaps, detergents, creams, shampoos, and other cosmetics.

Protein powder extracted from processed peanuts and defatted peanut cake can be used as an ingredient or additive in baked goods, meat products, dairy products, confectionery and fried foods. Foods with peanut protein powder as raw materials or additives not only increase the protein content, but also improve its functional properties. For example, in India, peanut protein powder (and full-fat soybean flour) are made into a mixed protein powder with protein content, which is used as a substitute for milk powder.

The peanut protein powder added to pasta in the United States has improved the nutritional value of pasta. The peanut protein powder added to noodles in China has multiplied the protein content and improved the cooking resistance of noodles. After the peanut protein powder is added to the enema, sausage and bun filling, the oil is not easy to flow out, the cooking is not deformed, and the food is not greasy.
