How to grow rape in autumn and winter? What should I pay attention to?

Increase boron fertilizer application.

Different types of rape have different requirements for soil available boron content. Boron deficiency can lead to physiological dysfunction in oilseed rape, which only blooms and bears little or no fruit. Boron fertilizer application in oilseed rape is generally insufficient, and it should be applied again before winter.

Pay attention to seedling fertilization.

Oilseed rape, especially hybrid rapeseed, has a strong growth advantage and requires a large amount of fertilizer at the seedling stage. In order to meet the nutritional needs of rapeseed growth and development, top dressing should be carried out according to different seedling potentials. Phosphorus can promote the development of rapeseed roots and enhance resistance. Potassium can improve the cold resistance, disease resistance and inverted hole ability of rapeseed.

The amount of nitrogen fertilizer should be appropriately reduced when fertilizing to prevent the plants from being tender and juicy and poor in cold resistance. For example, in a field with less than 10 green leaves in mid to late November, organic fertilizers such as pig manure, cow manure or soil fertilizer can be added between the rows of rapeseed, which can increase the ground temperature by 2 -3 and also have a winter-spring effect. Generally speaking, it is appropriate to apply 1000 kg to 1500 kg of pig manure and cow manure or 2500 kg to 3000 kg of soil fertilizer per mu; If the seedlings are smaller, they should be applied more.

For example, a field with 13 green leaves in late November with vigorous seedling growth and a field with dark green leaves can be retained or left unapplied.

Attention should be paid to field water and fertilizer management in winter rape planting.

1. Clean ditches, manage soil moisture, and prevent waterlogging. Entering the winter solstice is a period of cold waves, low temperatures, rain and snow. If there is a long period of low temperature and rainy weather, some poorly drained rape fields will suffer from serious waterlogging, and rapeseed is easy to freeze damage.

2. Reasonable thinning and strong seedlings. When sowing rapeseed, if the rain and temperature are suitable, there are many rapeseed seedlings and the density is too large, which is not conducive to cultivating strong seedlings and obtaining high yield of rapeseed.

3. Reasonable fertilization to promote growth. In view of the lack of growth in autumn of some direct seeding rapeseed, increasing winter fertilizer application is the key to promote the winter growth of weak seedlings and realize the upgrading of seedling conditions. For three kinds of rapeseed fields with thin growth, 7-10 kg of rapeseed special formula fertilizer or high-concentration compound fertilizer should be supplemented per mu as soon as possible.

4. Regulate prosperity and prevent frostbite. For rapeseed that grows too fast, winter fertilizer should be applied less or no winter, and 30-40 grams (15%) paclobutrazol or uniconazole should be sprayed per mu to control its growth and improve its strength, so as to improve the frost resistance of rape and achieve safe wintering. 5. Prevention and control of sclerotinia sclerotinia to ensure a bumper harvest.

1. Increase the amount of boron fertilizer 2. Pay attention to seedling fertilizer 3. Cultivate and weed 4. Strengthen pest control 5. Sowing must pay attention to the following matters: 1. Raise seedlings and set seedlings regularly. .

2. Strengthen top dressing, watering and cultivation management. 3.Early culture.

4 Top dressing. 5.Pour into three wells.

One is to pour back the green water, the second is to pour the flower water, and the third is to pour the grouting water.

When planting rape in autumn and winter, you must prepare the land and fertilize, the rape does not have high requirements for the soil, but likes fertile soil, and the seeds must be dried for 2 to 3 days before sowing, and the most suitable sowing temperature is 18 to 20 degrees.

Be sure to pay attention to the situation of top dressing, you need to choose the right variety for planting, pay attention to watering, pay attention to temperature, pay attention to the humidity of the air.

1. Planting time.

Rapeseed is suitable for growing in a warm environment, sowing rape can be carried out from spring to summer every year, the temperature at this time is suitable for the growth of rapeseed, you need to observe the weather before sowing, you need to choose sunny weather for sowing in spring, and you need to choose cool weather for sowing in summer.

2. Select the soil.

Sowing small oilseed rape requires the selection of suitable soil. Rapeseed is suitable for growing in the soil with rich organic matter content and loose soil, and can be planted with sandy loam or humus soil with rich trace element content and good drainage.

3. Sowing and planting.

When sowing, you need to select seeds with healthy growth and full grains, then soak the seeds in potassium permanganate solution to sterilize, take them out after a few minutes, rinse them with clean water, put them in the sun to dry, wait for the water to dry, and then sow them in the soil prepared in advance, and cover them with fine soil.

4. Later maintenance.

In the later maintenance of small rape, you can water mineral-rich natural water or pure water to the soil to keep the soil in a moist state, and you can also provide well-rotted organic fertilizer for the small rape, improve the growth rate of the plant, and also provide all-day sunshine for the small rape, so that the plant keeps the leaves green.

Rape is divided into winter rape and spring rape. Winter oilseed rape is generally planted in late September and matures at the end of May of the following year. Spring rape is generally planted at the end of April and does not mature until around September.

It is best to choose weakly alkaline soil when sowing rapeseed, and then spread the seeds evenly in the soil, and then cover with a thin layer of soil, and then water properly. As long as the temperature is around 16 -22, it can germinate smoothly.

1. Rapeseed planting time and method Rapeseed is divided into winter rape and spring rape, as the name suggests, it is rape planted in winter and rape planted in spring, so the planting time is also different. Winter rape is generally planted at the end of September and matures in May of the following year. In the case of spring rape, it is usually planted at the end of April and matures at the end of September.

When planting, the soil should be turned over first, then compound fertilizer should be applied, and then the seeds should be evenly sprinkled into the soil, and then covered with a thin layer of soil, and then properly watered.

2. Characteristics of raperapeRape is generally not used as an edible vegetable, but is generally used as an oil crop. It is sometimes used as feed for animals. Rapeseed belongs to the cruciferous family, also known as rapeseed, also called oil cabbage.

The stems and leaves are dark green in color, and the gang is similar to that of cabbage. Rape can also be distinguished by the color of the petiole between white stem and green stem. In the case of white stems, the leaves are green, the petioles are white, erect, and they taste bitter with a little sweetness.

In the case of green stems, the leaves are green, the petioles are pale green, and the petioles are flat and slightly concave, and the plants are relatively small, but fat and erect, the leaves are relatively thick, and the texture is very crisp and tender.

Yes, canola can now be grown; Rapeseed is generally planted in April and October, and it is necessary to provide a fertile soil when planting, to do a good job of water and fertilizer management, and to cover the mulch.

Now it is possible to grow rapeseed, rape is generally around October every year, planting we should plant rape when the distance between each seed should be about 10 cm, which is more conducive to its growth.

It is no longer possible to grow rape in the current season, because it is already past the season. It is better to plant in May and June, but it can also be planted in April because it will produce a better harvest.

After transplanting, it is cultivated once, and then deep ploughing and fertilization from the end of December to the beginning of January of the following year, and proper ridge formation. Drought-resistant top dressing. Rape needs water and has been afraid of water all its life.

In the early season, it is generally watered with thin manure water, and furrow irrigation can also be used, but ridges cannot be used to remove early tendrils. Oilseed rape, late early maturing varieties or early medium maturing varieties, which lead to early flowering, must be picked in time. Choose a sunny day to pick and dress appropriately after picking.

Prevention and control of frost damage. Oilseed rape is a low-temperature tolerant crop, but too low temperatures can cause frost damage. When the temperature rises after freezing, the frozen leaves and frozen ginger should be removed in time, and the fast-acting fertilizer should be appropriately applied, which is conducive to the recovery of rapeseed growth.

The key to seedling management, seedling determination, and supplemental winter rape planting is to improve the seedling emergence rate, ensure the quality of seedlings, strengthen the observation of seedlings, timely check and replenish seedlings, and do a good job in winter rape seedlings with rich planting experience.

It is necessary to adopt scientific methods of sowing. According to the actual situation of the winter rape planting plot, different planting methods such as sowing and strip sowing are adopted in a targeted manner. Generally, the geographical conditions of the planting plot are superior, and direct seeding can be used after appropriate rest, which is more conducive to improving the absorption of soil nutrients by winter rapeseed, but it is not appropriate to blindly expand the sowing amount of winter rapeseed to avoid uneven seedling emergence.

Secondly, the growth of seedlings should be carefully observed when planting, so as to effectively prevent the phenomenon of lack of seedlings and broken ridges. Therefore, thinning, fixation and replanting should be selected in time according to the planting situation of winter rapeseed to improve the overall quality of planting and achieve the purpose of effectively controlling planting density.

If it is a field with a large planting density, it is necessary to timely the seedlings to avoid the phenomenon of multiple seedlings co-squeezing, and the weak seedlings can be cut off in time to support the strong and move the weak. Thinning should be carried out when there is only one true leaf in winter rape, and thinning should be carried out when there are 2 or 3 true leaves in the second thinning operation if necessary. When thinning seedlings, reasonable disposal should be carried out according to the density of seedlings to remove dense planting areas, and diseased and weak seedlings should be eliminated in time, and disease-free seedlings should be left selectively.

When winter rape grows to 4 or 5 true leaves, seedlings can be determined, which should be reasonably and strictly controlled, and determined according to the variety characteristics of seedlings. The operation of the seedling assay should also be carried out according to the soil conditions in the morning and evening. Maintain the fertility of the planting area reasonably, and control the seedling density at about 10,000 hm2.

If the winter rape sowing time is late, the seedlings can not be determined before the year, the problem of broken ridges should be solved, the seedlings should be thickened according to the actual situation of the community, and the water supply should be strengthened when replanting. Cultivating and mid-ridge cultivation are important means to ensure cultivation quality, reduce cultivation problems and improve cultivation efficiency. Scientific tillage and ridge forming methods should be adopted to achieve the purpose of increasing ground temperature, ensuring soil environment, effectively removing weeds in the field, and effectively controlling pests and diseases.

The key to medium-term cultivation is to control the depth of the cultivation soil, loosen the soil in time, improve the overall cultivation quality, facilitate deep root infiltration, improve the lodging resistance of winter rapeseed, pay attention to soil cultivation before wintering, prevent root injury, appropriate fertilization, and effectively prevent leaf pressing.

It is necessary to weed regularly, because if you don't go on a business trip, the grass will fight for nutrients for the crop, resulting in the crop not growing.

The general sowing of rape is the method of direct replanting, so the sowing amount will be relatively large, and the seedlings will be uneven, and it is easy to break the ridge and lack the seedlings. Thinning is required where the density is too high. Avoid crowding of rapeseed seedlings and affect the growth of seedlings.

Seedling thinning is carried out when the seedling has developed one true leaf, and another seedling is carried out when the second to third true leaf appears. When there is too much rain, the soil moisture will be too large, and the rape will have rotten roots and sclerotinia disease, so pay attention to good drainage. In the middle, we should also pay attention to loosening the soil and do a good job of soil finishing.

Scientific fertilization.

1. Winter rape is planted in the south, harvested around May, sown in autumn and flowering in spring, and planted in September and November every year.

2. The north is planted with spring rape, the planting time is the spring of each year, the temperature in the autumn and winter in the northern part of our country is low, so most of the spring rape is planted, and if it is sown in autumn and winter, it is necessary to pay attention to anti-freezing, and it is harvested in April and September every year.
