How many days does it take for rapeseed to sprout?

Rapeseed is the most important oil crop in China and is widely planted in all parts of the country. It has a long flowering period and bright yellow flowers, making it ornamental. It attracts a large number of tourists every year to enjoy the flowers. It is also one of the flowers sought after by beekeepers. So, how many days does it take for rapeseed to germinate? Let’s take a look below.

1. How many days does it take for rapeseed to sprout?

Rapeseed will generally germinate 7 to 10 days after sowing. Of course, the specific time of rapeseed germination will vary due to differences in temperature, light, moisture, air permeability, etc. of the maintenance environment. Factors that affect rapeseed emergence include:

1. Temperature: The suitable temperature for rapeseed to germinate is between 15 and 20 degrees Celsius. After sowing rapeseed, pay attention to maintaining the temperature of the seedling environment; if the temperature is too low, cover it with insulation film in time to maintain a certain temperature to assist the rapeseed seeds in germination.

2. Light: Rapeseed requires an environment with sufficient light to germinate. Insufficient light will affect the growth and development of seeds, making it difficult for rapeseed to germinate.

3. Water: Adequate water is an important condition for rapeseed seeds to germinate. When rapeseed seeds are sown, they will quickly absorb moisture from the soil. When a certain moisture content is reached, the rapeseed seeds will break through the soil and sprout. Therefore, after sowing, pay attention to maintaining the moisture content in the soil so that the rapeseed seeds can germinate smoothly.

4. Air permeability: The air permeability of the soil is also important for the germination of rapeseed seeds. If the soil has poor air permeability, it will directly affect the respiration of rapeseed seeds, thereby affecting the normal development of the seeds, and ultimately leading to the failure of rapeseed germination. Therefore, before sowing, the soil should be fully tilled and base fertilizer should be applied to loosen the lumps of soil and improve soil permeability.

5. Variety: In addition to the above factors, different rapeseed varieties will also affect the germination time. Therefore, before planting rapeseed, it is necessary to select rapeseed varieties based on climate, disease resistance, growth rate and market demand, so as to select suitable rapeseed varieties that can germinate smoothly at the expected germination time.

2. Rapeseed Planting Method

1. Choose the right variety

Selecting the right variety is the key to successful rapeseed cultivation. When choosing varieties, you need to consider factors such as climate, soil, pests and diseases, as well as market demand and the quality and yield of the variety. Generally speaking, high-quality, high-yield, disease- and pest-resistant varieties suitable for local cultivation are better choices. At present, the varieties with relatively large planting areas and high yields include Qinyou No. 10, Zhongshuang No. 12, Qinyou No. 2, Qinyou 797, Qingza No. 7, etc.

2. Land preparation and sowing

Before planting, the land needs to be carefully prepared, including plowing, breaking up the soil, and leveling, in order to improve the physical and chemical properties of the soil and enhance its ability to retain water and fertilizer. While the land is being prepared, sowing can be done. When sowing, you need to pay attention to the sowing amount and sowing method. Rapeseed is generally sown directly by row sowing or spot sowing, and the seed rate per mu is 0.5-1 jin.

3. Fertilizer and water management

Rapeseed requires adequate nutrients and water to support its growth. Before planting, sufficient base fertilizer needs to be applied. Generally, 1000-2000 kg of farmyard manure and 50 kg of 45% high-potassium compound fertilizer are applied per mu. During the growth period, topdressing is also needed, which is generally carried out twice, the first time before the rapeseed seedlings enter winter, and the second time before the rapeseed blooms. At the same time, timely watering is needed during drought to ensure the normal growth of rapeseed.

4. Pest and disease control

Rapeseed is susceptible to diseases and pests, such as clubroot, sclerotinia, downy mildew, aphids, etc. In order to prevent and control diseases and insect pests, it is necessary to strengthen field management, remove weeds and diseased leaves in time, and maintain field hygiene. At the same time, you can also choose appropriate chemical agents for prevention and control, such as spraying pesticides , but you need to pay attention to the amount and safety.

5. Harvest and storage

When rapeseed is ripe, it needs to be harvested in time. When harvesting, you need to pay attention to the weather and harvesting methods to avoid losses to the rapeseed. After harvesting, the rapeseed needs to be dried and stored to prevent it from deteriorating during storage.
