I grow a lot of rapeseed at home, how should I manage it in the field in winter?

Winter temperatures are cooler, but aphids are at their peak when the temperature warms up. The number of aphids should be observed in a timely manner. The amount of Wudang aphids reaches about 20%, and 100 grams of infrared should be sprayed per mu, and 60 catties of water (about 2 points**).

If the one-time killing is negative, you can spray it again every other week. We grow rapeseed in our hometown, and that gentle slope is planted in large quantities every year, and it will be harvested in May next year, but to increase the yield, we also need to pay attention to management challenges. Especially in winter, we must deal with all kinds of management problems.

Only in this way can safer wintering take place and stronger rapeseed seedlings can be developed.

Canola was sown too early. If the growth is relatively vigorous, chemical treatment must be carried out in time at this time. A certain amount of multi-effect can be sprayed.

This makes the canola stronger. Even cold air can survive the winter well. Generally, add 30 grams per acre for multi-effect, and give 30 to 40 kilograms of water is fine.

For rapeseed fields with poor quality, we must cultivate loose soil in time to have a good seedbed control effect. Loose soil should be sprayed with winter fertilizer. For example, it is necessary to add rotten rice cake fertilizer and fertilizer, grass and trees, and fertilizer of about 3,000 catties per mu.

This effect is very good, which can produce the effect of raising the ground temperature and can make the antifreeze effect stronger. Rapeseed can survive the winter better, and the structure of the soil can be better improved.

Of course, in winter, the temperature is low and the soil is dry. At this time, weeding will speed up the death of the grass and the effect will be better. Sprouted grass can also be removed to avoid the hidden danger of herbicides.

Of course, after entering the hole, it is necessary to build a drainage system to drain the stagnant water in time to avoid rain and snow. Rape is easy to be attacked by vegetable insects, mites, etc., and is susceptible to downy mildew before entering winter, so it is necessary to spray it in time to avoid winter. When it comes to spring grass, vegetable aphids, black spot disease, gray mold, etc. will also be overflowing, and everyone should use medicine in time to prevent it.

When rape enters winter, field management should do a good job in winter fertilizer, field weeding, drainage prevention, cold prevention, disease prevention, pest prevention, etc., so as to cultivate strong rape seedlings and survive the winter safely. Fertilize the feet, winter. Rapeseed has just entered winter, and the temperature during the day is mostly around 15, so seize this time to top dressing and overwinter.

Winter fertilizer is a fast full-price fertilizer, which not only promotes the vegetative growth of seedlings, but also the beginning stage of reproductive growth, plays a very big role in promoting the physiological differentiation of rape flower buds and leaf buds and the accumulation of differentiation substances, and is also an important factor for planting strong seedlings for safe wintering. At the end of winter, the moss should be harvested to ensure the nutritional needs of the moss.

Cultivating soil. After transplanting and surviving, the cultivation is carried out once, and from the end of December to the beginning of January of the following year, combined with fertilization, one more deep cultivation is carried out, and the soil is properly cultivated. Drought-resistant top dressing. Rape needs both water and fear water throughout its life. To remove early sprouts, it is also necessary to protect against freezing.

Try to let it flow out of the growing space and avoid piling up too much, which is not conducive to the growth of vegetables. And it is necessary to fertilize regularly to provide nutrients. Watering should be moderate, do not water frequently, so as not to rot roots.

Cover with plastic wrap. In winter, when the temperature is low, a layer of plastic wrap on the outside is conducive to protecting the seedlings, thereby promoting the growth of the seedlings.

When rape enters winter, field management should do a good job in applying sufficient winter fertilizer, field weeding, drainage and preventing trouble, cold and frost, and prevention and control of pests and diseases, so as to cultivate robust rape seedlings and safely overwinter.

First, apply enough winter fertilizer. Rapeseed has just entered winter, and the daytime temperature is mostly around 15, seize this time to apply overwintering fertilizer. Winter fertilizer is suitable for fast-acting full-price fertilizer, which not only promotes the vegetative growth of seedlings, but also the initial stage of reproductive growth, and has a very great effect on promoting the physiological differentiation of flower buds and leaf buds of rapeseed and the accumulation of differentiating substances, and is also very important for cultivating strong seedlings and safely overwintering.

By the end of winter and the beginning of spring, it is necessary to apply moss fertilizer to ensure the nutritional needs of moss.

Second, weeding in the field. In winter, the use of low temperature, dry soil, seize the sunny day, artificial weeding, fast dead grass, good weeding effect, can kill the grass buds that have sprouted, and avoid many unfavorable factors brought by the use of herbicides in the world.

Third, drainage and stain prevention. In winter, the drainage system should be repaired to drain the stagnant water in the fields. Prevent the accumulation of water in the bend of the rain and snow hall and the effect of impregnation on rapeseed.

Fourth, cold and frost protection. In winter, the climate changes impermanently, and it is necessary to prevent the sudden attack of cold air and frostbite on rapeseed. When weeding, the rape part can be cultivated to keep warm.

Before the arrival of cold air, the use of fallen leaves, straw debris, sprinkled between the rape gaps, can play a cold and frost prevention effect.

Fifth, control pests and diseases. Rapeseed in late winter and early spring is a good period for the control of gray mold, downy mildew and black spot and vegetable aphids. It is necessary to seize this favorable time to take medication.

Rape is also called bitter cabbage, oil cabbage. In China, rape is mainly distributed in Sichuan, Anhui, Henan and other places. In our rural areas, it can be said that many farmers and ordinary people grow rapeseed every year, just to sell it for money.

The flowers of the rape are yellow and beautiful. In addition to our common rape flowers can enjoy flowers, increase economic income, the main role is to harvest rapeseed, rapeseed as an important edible oil raw material crop, the economic value is still good, at least we eat more assured, many places are their own rapeseed.

Rapeseed seedlings are a good green fodder, which is very good for feeding pigs, cattle and sheep. Rapeseed cake can be turned into a good feed after fermentation. The rape cake is crushed, fermented together with corn flour, wheat bran and other energy feeds, and 2 1000 Gymboree feed starter is added to the rapeseed with strong adaptability, low planting cost, simple field operation management, and is in the busy interval period of autumn, winter and summer, so farmers everywhere should plant rapeseed.

Every year, the spring flowers bloom, the earth thaws, the rape flowers rush to bloom like a trip, and the whole field is golden everywhere.

Rapeseed ** in Europe and Central Asia, since the founding of the People's Republic of China, rapeseed has become China's main oil and economic development crops, rapeseed oil yield is very high, the highest oil yield can reach about 45 percent, and rapeseed growth conditions are not so harsh, all the fields in the ravines and hills of course one is edible, rapeseed oil nutritional value can be said to be very high, with softening blood vessels, and even delaying aging, often practical rapeseed oil, can regulate blood pressure, Boosting our immunity also helps us sleep.

At the end of the twentieth century, the output of tea oil decreased sharply year by year, the labor went out, the tea mountains were barren, and the air pollution was serious, some tea mountains were burned, even if there were tea trees, when the tea seeds were harvested, there were few, and now there was almost no tea oil The plant fiber in rape can improve intestinal function and prevent constipation. Rape is a low-fat vegetable that can be combined with cholesterol and has a lipid-lowering effect.

When planting rapeseed, you must ensure sufficient water, and then water it with more urea or ammonium bicarbonate at ordinary times, and then ventilate them more, so that the rape planted is particularly high-yielding.

You should choose a place with a better environment for planting, and you should also choose a place with fertile soil, followed by the management of water bills, and you should also spray pesticides in time to keep the light sufficient.

First of all, before planting rapeseed, be sure to turn the soil soft, and then sprinkle with base fertilizer, you can use sheep manure or chicken manure, and then gently cover with soil, planting rape seeds, and be sure to pay attention to watering, you need to water once every two days, fertilize once a week, you can wait for the harvest.

Be sure to water properly, the amount of water needed for rape is still quite large, and we must pay attention to the density between seedlings, and carry out proper fertilization, and need to spray some pesticides to prevent some pests and diseases.

Keep the soil in a relatively moist state, pay attention to the distance between plants, and after the first true leaf appears, it is necessary to supplement fertilizer in time to prevent aphids and cabbage insects from harming them, and dry them in time.

The frost solar term has passed, in the real sense of the cold winter is coming, and live at this time, transplanted rape seedlings have also been put into the management of the wintering period, all say that the rape seedling period is a critical period of life, before the plant can reach the roots, leaves, thick green leaves and other standards, it is related to the high yield of rapeseed, so after the rape seedlings emerge, the correct seedling field management is the top priority of cultivating strong seedlings before winter!Now I will share with you how to carry out field management of rape seedlings at the seedling stage!

<> transplant strong seedlings. Rapeseed seedling transplanting is an important measure in production, transplanting can be arranged at the appropriate time, can ensure that the seedling condition is comprehensive, better management, high yield, transplanting time is generally in mid-October, choose seedlings aged in about 40 days, more than six leaves, 20 cm high, no plant pests and diseases of rape seedlings thick half a centimeter, minimize damage to the roots, deep ploughing to the lower part of the leaf base, and do a good job of water accumulation in the roots. The requirements are basically the same as pre-seedling treatment.

This herbicide is sensitive to beans and peach trees, and should be used with strict care.

The principle of fertilizer and water. In order to cultivate rapeseed wintering hail filial piety strong seedlings, in addition to the selection of strong seedlings transplanting, but also timely check the seedlings to supplement the post to protect the seedlings, now the temperature drops very quickly, in the years ago the principle of rape fertilizer and water is mainly to eat less and more meals, first light and then thick, water and fertilizer in one, to nitrogen seedlings, increase its absorption capacity. In addition, in late December, wax fertilizer pile seedlings can be re-applied for heat preservation, 20 kg of compound fertilizer + 2000 kg of farm fertilizer per mu, combined with mixed cultivation, and winter irrigation begins when the temperature drops below 5, which is more conducive to the wintering of Zhuangyuan noisy seedlings.

Boron fertilizer can also be sprayed if conditions permit, which can greatly help increase yields.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your praise is the biggest help to me, thank you.

Pay attention to the management of temperature, the appropriate temperature is 20 degrees left, planting rape for about 7 days, timely fertilization, do a good job of checking seedlings and filling the gaps, choose disease-resistant fiber attack products, rent macro species, and avoid downy mildew.

First of all, we should choose high-quality varieties based on rent, and then we should also water and fertilize in time, strengthen the management of water and fertilizer, ensure the sufficiency of light, and also need timely loosening of the soil, ensure the permeability of the soil, drainage and ventilation work, and also need to spray some nutrient solution regularly.

To carry out scientific and effective management, the planting density must be divided into good guesses, and the management of the planting field should also be planted, pay attention to regular topdressing, and also spray some pesticides to prevent and control pests and diseases, so as to be able to manage well.

If there is a reasonable interval, each rape seedling can fully venerate to the sun, but also need timely watering, add fertilizer to choose some farm fertilizer or organic fertilizer, hunger eggplant to improve the fertility of the soil.

It is necessary to pay attention to the density of planting, the selection of varieties, the temperature, the drainage of the soil, and the timely spraying of pesticides.
