How do you harvest lettuce seeds? When is canola harvested?

How to harvest lettuce seeds, first wait for growth and then grow, don't pinch off his tip in the future, and then wait until he sees the flowers ripe. Look at him. The rapeseed on top is already dry, so you pull it off and rub it dry. You can put it away, and that's how the lettuce is received.

How lettuce seeds come from.

The seeds of lettuce grow on its cabbage, and when the vegetables are ripe, do not rush to harvest, a stem will grow in the cabbage, and the seeds will mature in the autumn, and you can harvest at this time.

After the lettuce seeds are harvested, they should first be screened, and all the deflated and pests should be removed, and then the seeds should be dried and stored in sealed containers such as jars and sealed bags.

What do lettuce seeds look like.

The seeds of lettuce are large, about 4 mm long, the whole is inverted-lanceolate, flattened, light brown in color, the fine veins on the seeds are obvious, and the tip is sharp.

How to grow lettuce seeds.

Lettuce seeds can be planted in spring, summer and autumn, and if they are in a greenhouse, they can also be planted in winter, and they can be matured and marketed in 100-120 days after sowing.

1. Seed germination: Lettuce seeds should be planted in loose and fertile soil, and farmhouse fertilizer should be applied to them, and sowing should be carried out when the seeds are germinated and exposed.

2. Sowing: Mix lettuce seeds with wet sand before sowing, and then use the method of sowing, cover the soil after sowing, and pay attention to the fertilizer and water management in the later stage.

1. First of all, choose loose and fertile soil and apply farmhouse fertilizer. 2. Then the lettuce seeds are germinated at low temperature, and the seeds are sown in time when the seeds are white. 3. Before sowing, mix the seeds with wet fine sand and spread them, and cover them with soil about centimeters thick.

4. Finally, pay attention to fertilizer and water management and pest control.

First of all, wait for the birth and then grow up, don't pinch off his tip in the future, and then wait until he sees the flowers ripe. Look at him. The rapeseed on top is already dry, so you pull it off and rub it dry.

You can put it away, and that's how the lettuce is received.

In order to receive lettuce, we first have to plant lettuce, and then harvest it when it is ripe, so that we have lettuce seeds.

First of all, the climatic factors in the north and south of China are different, and there are also differences in harvest time, among which rapeseed in the north.

The harvest time is not much different from the wheat harvest time, about 5-10 days before and after the wheat harvest, and in the southern region.

The normal harvest time is close to that of the first crop of rice, and in some areas it is in Xiaoman.

Harvest before and after or before planting.

The best way to harvest rapeseed is to what extent.

Observe the color of the rapeseed in the field, first observe the rapeseed field, the rapeseed fruit in the whole field is slightly yellow, and more than half of the rapeseed fruit in the field turns yellow-green, and one-third of the whole rapeseed fruit is green, which is suitable for rapeseed harvesting. Look at the flowering date and time: In general, you can see rape flowers.

The flowering period is about 25-30 days after the end of the rape flowering period, which is also the time of rape harvesting. Look at the color of the grain to judge: you can randomly pick different parts of the rapeseed, peel off the grain to observe the color, brown grains or half brown and half red grains, this is also a suitable harvest period.

Precautions for rape harvesting.

The harvest period of rapeseed is short, so we should grasp the harvest time, and it is best to harvest it with dew in the morning on a sunny day, which can effectively prevent the rapeseed from cracking and falling off. Moreover, it is necessary to handle the rapeseed with care during the harvesting process to minimize the loss of rapeseed harvest as much as possible.

Finally, I would like to remind everyone that after the rapeseed is harvested, it should be spread out in time to dry, threshing and drying on a sunny day, or when harvesting, it is necessary to bundle while harvesting, and do not put it directly in the field to pile up and dry in order to save trouble, so that the jujube chain will cause unnecessary losses.

In late April every year, all the leaves of the rape are dropped, and at a glance there are full of rapeseed pods, and the color gradually changes from green to yellow, indicating that the rapeseed is gradually ripe and can be harvested. Unlike the plains, where there are large harvesters, the rape harvested by farmers and uncles still rely on traditional manual harvesting methods in mountainous and hilly areas.

China's sales are divided into two major production areas: winter rape (planted at the end of September and harvested at the end of May) and spring rape (planted at the end of April and harvested at the end of September). The area and yield of winter rape accounted for more than 90%, and the main pants rock should be concentrated in the Yangtze River Basin, and the spring rape should be concentrated in the northeast and northwest regions, with the Hailar area of Inner Mongolia being the most concentrated.

1. Rape is a cruciferous family, brassica, an annual herb with straight roots, erect stems, and few branches.

2. After about 2 months, it will grow into shape. Then, the flowers begin to grow.

3. From the end of the flowering period to the end of the flowering period, it takes about 2 months.

4. After the flowering period, it will bear fruit and form rapeseed, and wait for the rapeseed to mature for about a month. Farmers can harvest, and after harvesting, fry vegetable oil. In this way, our fragrant vegetable oil comes out.

There are two types of rapeseed, those planted in spring can be harvested in autumn, and those planted in summer can be harvested in late autumn.

1. Harvesting method: rape harvesting should be harvested with dew in the morning, so as to prevent the main shaft and the upper branch corner fruit from splitting. When rape is harvested, it is harvested, bundled, pulled, and piled up, and should not be stacked in the field.

2. Stacking and ripening: In order to promote the post-ripening of some incompletely ripe horns, they should be stacked and ripened in time. The stacking method is cylindrical, square, etc., and it is necessary to choose a place with higher ground and no water accumulation, moisture-proof and anti-wisdom stool to stop rapeseed mildew.

3. Threshing: After 4-6 days of rapeseed stacking, the horn fruit is decomposed by pectinase, the slag of the horn peel is cracked violently, and the rapeseed has been separated from the horn peel, you can choose a sunny weather, the rape is dried, milled, threshed, and cleaned, and when the rape moisture drops to 8-9%, it can be put into storage.

Hello, because rapeseed is cultivated all over the country, so the harvest time varies.

In the middle and lower reaches of the Yangtze River in China, sowing began in early September, and harvesting began around April 25 of the following year. Thank you.

When ripe, it can be harvested. The exact harvesting time depends on the time you plant, and the best thing is to see that it is ripe and harvested quickly.

Generally, rapeseed harvesting on both sides of the Yangtze River is around the fifth month of the lunar calendar.

The time of rape harvesting is different in the east and west, south and north of the motherland. Generally speaking, the northern, eastern and western regions are about the same as the wheat harvest time, and the wheat harvest time is about five to ten days earlier. The western part of Shandong is in front of Xiaomanqiaorang, the central part is in front of the mangs, and the east of Jiaodong is behind the mangs.

In the south, the harvest period is similar to that of the first crop.

Harvest with a hammer knife, dry it in the sun, take a large cloth or something, take a nunchuck, and beat the seeds.

Summary. The growth cycle of lettuce is 100-120 days, while the growth cycle of lettuce is 60-90 days.

The growth cycle of lettuce is 100-120 days, while the growth cycle of lettuce is 60-90 days.

Non-bulb lettuce is transplanted and planted in spring and autumn, the seedling period is about 25 days, and it is harvested about 35 days after planting (

When to harvest the seeds of bulb lettuce?

There are two seasons. 5 June.

and 10 November.

Will the seeds that were injured in October last year germinate now this year?

Germination is likely to occur at the end of November this year.

Are you **?

How cold is it in winter?

I am from Jianyang City, Chengdu, Sichuan.

Is it cold in winter? It wasn't much cold in winter.

In other words, the seeds that were planted in October last year will germinate now this year, right?

Yes. I'm a small merchant who retails seeds, and in order to be responsible for customers, so I ask, yours is right, right?

Correct, as long as the seeds are not damaged, they can be harvested around December this year, and they will germinate in October.

When planting rapeseed, you need to choose seeds with full particles and no insect pests, and then soak the seeds in warm water at 30 degrees for 5 hours.

1. Germination and awakening

When planting rapeseed, it is necessary to select the rapeseed seed with full particles and no pests for germination, when germinating, the rapeseed seed needs to be placed in warm water at 30 degrees to soak for 5 hours, after the soaking is completed, the seed is taken out and placed in a warm place, and the seed can be sown after half of the seed is exposed.

2. Seeding depth

When rapeseed is sown, the soil needs to be kept flat, and then the seeds are evenly sprinkled on the soil, and then the soil is covered, and in the process of covering the soil, the thickness of the covering soil can not exceed three centimeters, so as to avoid the situation that germination is slow or even unable to germinate.

3. Lighting conditions

Rapeseed is a light-loving plant, so when sowing rapeseed, it should be selected to sow in a place with better light conditions, which is conducive to photosynthesis of plants and provides nutrients for its growth.

4. Soil conditions

When planting rapeseed, it needs to be sown in loose and fertile soil, and inorganic fertilizers need to be applied regularly to maintain the fertility of the soil, and at the same time, drainage measures should be taken to avoid excessive soil waterlogging, so that the plant has rotten roots or even died.

1. When planting rapeseed, it should be germinated first, and it should be soaked in warm water for five or six hours.

2. After soaking, take it out and put it in a warm place, and when 50% of the seeds are white, you can sow them.

3. The planting method is very simple, after the plot is processed, the seeds can be sprinkled on it and covered with thin soil in time.

4. Observe the growth of rapeseed in sowing logistics and strengthen the prevention and control of pests and diseases.

How did the rape seeds come about.

Generally, the seeds of oilseed lettuce are bought from the hands of medicinal fertilizer dealers. The seeds are flattened, milky, the leaves are oblong or lanceolate, the inflorescences are capitate, and the flowers are yellow.

Seed dispersal of lettuce.

The fruit of oilseed lettuce is a pod that cracks when ripe and then falls to the ground. It can also be spread by animals or artificially cultivated.

How to get rape seeds.

When the seedlings are thinned, the oilseed rape is already ripe, and the oilseed rape can be harvested at the top, dried and preserved, or sown in time. Oil-010 to 1010 wheat seedlings can be eaten with imitation stupidity. When the height of oil wheat seedlings is 20-30 cm, they can be picked intermittently.

When the height of the oil wheat seedlings is 35 cm, they should be picked at one time at the right time. If the best time to harvest is missed, it will become old and hard, and the seed plant will be preserved, allowing it to sprout, flower, and set seeds on its own.

How to keep seeds in oily lettuce.

Oilseeds can be sown all year round. The temperature in the north is low, so it is best to grow it indoors. The best time to plant is from August to September every year.

Cabbage seeds need to be soaked in cold water for about 1 hour, and then placed in an environment of 15-20 degrees to germinate. Once the seeds turn white, they are ready to be planted. When the seedlings have grown two true leaves, the seedlings can be interspersed to keep the soil moist.

These plants are not tolerant of bright light, so they need shade at noon. At the same time, it is necessary to pay attention to the control of pests and diseases at the seedling stage.
