Is it better to plant rape in autumn or spring?

Rape flowers can be planted in autumn, winter and spring, autumn and winter planting needs to be planted from September to November, and it is better to plant in April and May in spring, but the planting time is different in different regions, because the temperature and environment are different, so the planting time will be different.

The central and northern regions of China are the main rapeseed producing areas, which are mainly sown after the harvest of corn in autumn, and rarely in spring. If it is sown in the spring and harvested, it will affect the planting of the next crop, so it is mostly sown in the autumn.

The planting of ornamental rape flowers is mainly determined according to the ornamental period, generally speaking, the rape flowers sown in autumn around October will bloom in March and April in early spring; If it is planted in early spring, it usually blooms in May and June, so we can determine the specific time of rapeseed planting according to the requirements of the viewing time of the site.

Planting time, in general, rape is sown in autumn and winter, and flowering in spring, but spring planting is also possible in some areas.

Planting method, before sowing, the land should be watered again, and after two days, the compound fertilizer should be sprinkled and the soil should be turned over again.

You can choose the method of direct seeding, sow rapeseed in rows at certain intervals, and pull out the denser places after the seedlings grow.

When the rape grows to 15-20 cm, the vegetable field should be fertilized and weeded once, and the fertilizer applied this time is urea, the purpose is to grow seedlings.

When the rape grows to about 40 centimeters, the second fertilization is carried out, and the fertilization is farmhouse fertilizer.

The last application is to spray Pica Boron fertilizer before flowering, which will help to make the fruit more abundant later, and it can be harvested when the whole canola horn is yellow-green.

In the case of rape, it is usually planted in the fall, and then when it grows to a height of about 10 cm, it is generally winter, and it will snow in many places.

Rapeseed can be planted in spring and autumn, but the quality of rape planted in autumn is better, if planted in spring, rape is easy to sprout and flower and set seeds, because in such a season rape has to reproduce offspring, so it is easy to grow old in spring. If planted in autumn, because the weather is getting cooler, rape generally does not flower and set seeds, so the autumn rape is very tender to eat.

In the southern zone, rape flowers are planted in autumn, usually sown in mid to late September, transplanted in October, flowered in March of the following year, and harvested in May.

It's all right. Rapeseed can be planted in April or September in autumn every spring, and the humus soil with rich trace element content and good drainage can be used for planting rape, and after planting, it can be regularly watered for rape to keep the soil moist, and it can also be supplemented with fertilizer for rapeseed, so that the plant can grow more vigorously.

Rapeseed planting can be in autumn or spring, the north is generally planted in autumn, and the south is mostly planted in spring, which time is better? The key depends on what the place is.

Rape is planted in spring and autumn, but I love to wear moss in spring, and in autumn, because it is airless, it is gradually cool, and rape does not like to wear moss, and the weather is cool, and rape is tender, so it is better to choose to plant later.

The planting season of rapeseed mainly depends on the local climate, and it can be planted in autumn where the temperature is a little higher.

In our north, rape is sown after the autumn equinox of the solar term and harvested before the next year.

Planting time of canola.

China's rape is generally planted in autumn and winter, that is, around September to November, and can be harvested in May of the next year, this time period of planting is more suitable, and the suitable temperature can ensure the growth, which belongs to the winter rape, generally concentrated near the Yangtze River Basin, the planting area is relatively broad, and the proportion is also very large. The planting time is different in different regions, and there is spring rape, which is planted around the end of April and can be harvested in September, and the planting locations are concentrated in the northeast and northwest regions of China.

2. Planting method.

1. Leveling the land: before planting, we must choose a good location, the requirements for this aspect are not very high, you can choose a sunny place, and the land must be leveled before planting to maintain the activity and softness of the soil.

2. Sow seeds: buy better quality seeds in advance to ensure the chance of survival. Spread the seeds into the soil, keeping a certain spacing.

Pay attention to follow-up management, contact with sufficient light, observe the moisture content of the soil surface, and replenish water in time. Once the seedlings have grown, remove the weeds from the side to make sure they don't rob the plants of nutrients.

Canola is generally sown in autumn and winter, then flowered in spring and harvested in late spring and early summer, but some areas are also suitable for growing canola in spring.

Sowing too late, the temperature drop is not conducive to the slow growth of rapeseed seedlings, is not conducive to the safe wintering of rapeseed seedlings, the growth and development period is shortened, the growth after the year is poor, the total number of leaves, the number of branches, the number of horns per plant and the number of grains per horn of the main stem are reduced, and it also does not have the characteristics of high yield.

Timely sowing is an important measure for rapeseed to achieve high yield, and the middle and upper reaches of the Yangtze River basin should be sown in early and mid-September, and direct seeding rape should be delayed for 7 days.

Rapeseed can be sown in spring 3-4 months and winter in September, before sowing need to prepare the land, apply base fertilizer in the soil and carry out deep turning, and then sow rape seeds into the soil, after sowing well, you need to keep the soil slightly moist, rape seedlings can be planted when they grow for about 20 days.

The best time to plant rape is between September and November, and if it is planted and properly managed, it is generally ready to be harvested in May of the following year. There are also areas that are suitable for spring planting, which is planted at the end of April and harvested in September. Canola prefers a warm environment and also has some cold tolerance.

In order to promote its better growth, it is recommended to regularly top dressing and give sufficient light during the growing season, so as to promote vigorous growth and higher yield in the later stage.

Rapeseed is planted in April and September every year, the temperature at this time is about 25 degrees, which can meet the germination needs of rapeseed seeds, soak the seeds in clean water before planting, wait for it to be exposed, and then sow the seeds in the loose and breathable soil, and water the pollution-free water to help rape germinate and grow.

1. Sowing time.

Rape sowing time.

Rapeseed can be divided into two kinds: spring rape and winter rape, of which spring rape is sown and planted in April every year, winter rape is sown and planted in September every year, and the growth of rape has five months in the later stage, spring rape is harvested in September, and winter rape is harvested in May of the following year.

2. Sowing method.

When sowing rapeseed, the seeds with full particles should be soaked in clean water, wait for the seeds to absorb enough water, and then take them out and sprinkle them into the loose and breathable, well-drained soil, and water the rape once after planting, water all the soil and let the seeds germinate as soon as possible.

3. Supplement nutrients.

When rape is in the seedling stage, the demand for nutrients is greater, at this time it should be provided with nitrogen fertilizer, urea, improve the growth rate of the plant, but the seeds in the seedling stage have limited fertilizer absorption at one time, and the fertilizer should be diluted with water when fertilizing to avoid fertilizer damage to rapeseed.

4. Provide light.

Rapeseed in the process of growth, can not do without light, insufficient light will appear poor growth phenomenon, breeding rape to put into the sunny environment, to provide all-weather natural light for the plant, but the summer afternoon light is too strong, at this time to shade the rape.

1. Rapeseed planting time.

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

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, sowing in the autumn and winter, we need to pay attention to frost prevention, in April every year, harvest around September.

2. Rapeseed planting methods.

1. Choose high-quality varieties.

The choice of rape variety is crucial, depending on the local technology and climatic conditions. Combined with the local soil fertility and production status, select varieties with strong adaptability and good yield.

2. Transplant in a timely manner.

The seeds can be transplanted after one month, at this time, the rape has grown five or six leaves, has a good adaptability, it is the best time for transplanting, it is best to pick seedlings in the morning and cultivate in the afternoon, which is conducive to improving the survival rate.

3. Reasonable fertilization.

Fertilization can be carried out in three stages: first, fertilizer is applied before sowing, farmhouse fertilizer and water can be applied to the ground before leveling the land, and then the ground is turned over to level the ground and refine the soil, which is conducive to improving the germination rate; Then fertilize before transplanting, and at this time, organic compound fertilizer is mainly boron fertilizer, phosphate fertilizer, and potassium fertilizer. to increase the nutrients of rapeseed, so that rapeseed grows rapidly and draws green; Finally, fertilizer is applied before flowering and fruiting, mainly mixed with farmhouse fertilizer, urea and water, which has been used to improve the pod setting rate and increase the fullness.

4. Strengthen field management.

After 7 days of transplanting, observe the vegetable seedlings to see if they have been killed, and if there are any, they will be replanted immediately to ensure that the whole seedlings are replanted. Ditches are cleared to drain stagnant water in low-lying areas and reduce the occurrence of moisture and insect pests. After the rape is transplanted and turned green, the surrounding weeds should be loosened in time to avoid the weeds covering the rape.

Strengthen pest control, early prevention, such as pests and diseases should be sprayed in time.

Rapeseed can be planted in April or September in autumn every spring, and the humus soil with rich trace element content and good drainage can be used for planting rape, and after planting, it can be regularly watered for rape to keep the soil moist, and it can also be supplemented with fertilizer for rapeseed, so that the plant can grow more vigorously.

First of all, rape is generally sown in autumn and winter, and blooms in spring, but different regions have different temperatures and different sowing times. We have to prepare the land before planting, rape is not strict on the land requirements, if the soil is more clayey, we must first turn the soil over, expose to the sun, water it before sowing, and then fertilize the soil again after a few days. There are two ways to grow rapeseed, the first is to plant rapeseed in rows at certain intervals.

Rapeseed is the best to plant in autumn in our northeast, when it grows very lush, and rape is also quite delicious, with high nutritional value, especially stewed rape, which is very famous in our place.

Rape can be planted in spring, so let's listen to Xiao Wang tell you about the reasons.

1. The sowing time is closely related to the type of crop and the local climate

First of all, the type of crop determines the suitable temperature range for the crop, and the temperature range within which the crop should be able to grow throughout its reproductive life. Specifically, it is important that the temperature at which the seeds are sown is not only to ensure that the seeds germinate and emerge, but also to ensure that there is no frost at the time of harvesting.

Secondly, the local climate determines the planting date. Spring-sown crop varieties should not only consider the seed germination conditions, but also consider the cumulative temperature required during the reproductive period, try to avoid high incidence of pests and diseases, and make a comprehensive judgment on the sowing time.

2. Spring rapeseed planting technology

1.Ditch drainage

The heavy rainfall in spring not only seriously affects the normal growth and development of rapeseed, but also easily leads to the occurrence and epidemic of diseases such as gray mold. Therefore, the ditching and drainage of rape fields in spring should pay special attention to hidden lead, especially in cold-soaked fields and some poorly drained mountainous areas.

2.Spray boron fertilizer

Boron deficiency in soils is common, and boron deficiency in oilseed rape can lead to flowering and reflowering, so care should be taken to spray boron fertilizers. Boron fertilizer can be used in three ways: basal fertilizer, top dressing or foliar laming spray. For boron fertilizers without basal fertilizer, at the budding and early flowering foliar stages.

Boron fertilizer should be applied to rapeseed with strict soil and heavy boron deficiency and no bottom fertilizer, and boron fertilizer should be sprayed once at the seedling stage of rapeseed. Spraying boron fertilizer is generally 200 grams of borax per mu, dissolved in warm water, and sprayed with about 50 kg of water.

3.Application of moss fertilizer

In order to prevent late collapse and late maturity, fertilization is generally not advocated after the year, but for fields with insufficient wax fertilizer, poor growth and declining trend in the early stage, moss fertilizer should be supplemented with appropriate amounts. For fields with a lot of waxy fertilizer and strong growth potential, do not apply moss fertilizer anymore.

4.Remove old leaves

The plants are tall at the flowering and pod-setting stage, the lower part is poorly ventilated, and the spring rain in our province is more, and the field humidity is large, so the oil smoke point tester is easy to trigger oil diseases. Therefore, the lower non-functional diseased, old and yellow leaves should be removed in time to prevent and reduce the occurrence of diseases such as gray mold.

5.Prevent lodging

Hybrid rape plants are tall, and if they are poorly managed in the early stage, grow too much, or fertilize too much in the later stage, they can cause rapeseed to collapse. Especially in the Dongting Lake area, rapeseed is susceptible to the influence of spring breeze during the flowering period and causes rapeseed to fall in a large area.

After rape falls, it is also prone to re-flowering. When the rape falls, try to correct the plant by pruning some branches and leaving some cotton straw in the field as support. For fields with high humidity, pay attention to ditch cleaning and drainage.
