How to choose rapeseed? What are the methods of raising seedlings?

Rape is a very common vegetable in our life, which is easy to fry and delicious, so it is loved by many people. After a while, farmers will begin to grow crops. I believe most farmers will grow oil, wheat and vegetables. Then how to choose the seed of oil wheat vegetable? What are the methods of raising seedlings? Friends who want to know, read on!

First, how to choose rape seeds?

In the selection of rape, we should pay attention to select the varieties which are suitable for Rain Water, high humidity, strong resistance, strong fragrance and high yield. at present, the varieties widely used are fine unspotted wheat, four seasons concubine, big pointed leaf and so on.

Second, what are the seedling raising methods of rape?

1. Seedling plate

According to the needs and the characteristics of the variety, choose 54-hole or 72-hole seedling plate.

2. Seedbed

Set up the seedling shed before sowing, and make the bed according to the seedling shed, and cover the border with plastic film after leveling the border. If there is a conditional seedling shed, the electric heating pipe can be laid under the seedling bed, and the temperature of the small environment in the shed can be controlled in the later stage.

3. Sowing seeds

Before sowing, the matrix in the seedling plate is watered thoroughly, and then the germinated seeds are put into the holes of the seedling plate, and then covered with the matrix and scraped flat, watered, so that the surface matrix water content is about 50-60%, film mulching, heat preservation and moisturizing.

4. Post-broadcast management

After sowing, it is necessary to keep the temperature in the greenhouse at a suitable temperature of about 20 ℃. When more than half of the seeds in the seedling tray are unearthed, remove the plastic film in time, and then keep the temperature in the shed at 28 degrees Celsius, always pay attention to the moisture content of the matrix in the shed, and replenish water in time when there is a shortage of water. After finishing the seedlings, the temperature in the greenhouse should be reduced properly, and the seedlings should be refined to prevent the seedlings from flourishing and growing. After the seedlings grow 5-6 true leaves, they can be used for planting.

Although the incidence of diseases and insect pests in substrate seedlings is not high, once diseases and insect pests are found, it is necessary to take timely control measures and remove infected seedlings and weak seedlings.

3. Key points of high yield of rape and wheat.

1. Dig deep into the soil

Rape does not eat deep soil, but after years of planting, the nutrients in the surface soil are lower than those in the deep soil. After all, the deep soil not only has not been destroyed, but also has years of nutrient accumulation. Turning deep into the soil is to make the oil, wheat and vegetable have a better soil environment, because it grows very fast and can mature in a short period of 2 months, so it is necessary to use better nutritious soil to ensure its development. So the first step in high yield is to dig deep into the soil, which is about 15 centimeters deeper than usual.

2. Wide composting

Rapeseed needs plenty of fertilizer to meet its growth needs, so the initial compost is extra important, which is to mix the fertilizer with the soil and compost. At present, there are special soil loosening equipment in many parts of the countryside, where fermented manure is sprinkled on the surface of the soil and stirred with a loosening machine. After two times of mixing, some chemical fertilizers are applied and stirred three times, and then wait for three days before planting. Give the soil time to digest fertility, and then plant.

3. Control density

A rape needs a large amount of nutrients, so blindly pursuing high density is not a high-yield way, and it will only lead to unsatisfactory growth. Reasonable planting density is a great help for high yield. Density according to the local aquatic nutrition environment, the soil fertility is good, the distance between plants is controlled at about 10-15 cm, and the distance between poor fertility is controlled at about 15-20 cm. The span of each ridge is controlled at about 1.2 meters, with a drainage ditch of about 20 centimeters in the middle.

4. Keep moisture

Experienced growers know that the yield of rape and wheat in paddy fields is much higher than that in dry land. And at the beginning of the article, I told you that the water content of vegetables is very high, so the requirement for water is also very high, and the drains mentioned above can also be used for irrigation. The water in the rape field should keep the soil moist for a long time, and a small amount of water exists in the drainage ditch, so that it can build a moist growth environment for the oil, wheat and vegetable, and its leaves grow much faster, which has achieved the effect of high yield.

All right, that's all the editor wants to share with you. When choosing rape seeds, you should try to choose varieties that are suitable for Rain Water, high humidity, strong resistance, strong fragrance, and high yield. In addition, you can learn from some of the above methods in raising seedlings. If you want to have a high yield, you'd better master the above points.
