How to grow rapeseed, how to grow rapeseed, how to grow rapeseed

When planting rapeseed, it is necessary to choose high-quality seeds, which can be properly soaked in salt water for a while to remove impurities on the surface and also achieve the effect of disinfection. After choosing a lot with loose soil and convenient for irrigation, plough the land and apply fertilizer appropriately, and then you can sow seeds. Dig small ditches in the land, sow seeds on the slopes of the ditches, cover the loose soil after sowing, and water the small ditches.

Next, let's take a detailed look at the aspects of seed selection and soaking, land selection and soil preparation, and sowing.

1.Select the seeds to soak.

You can use the seeds from the previous year's rape flower pods to choose seeds with full grains and no pests. For the first time planting rapeseed, you can directly purchase excellent varieties with strong disease resistance and lodging resistance. Put the selected seeds in brine for disinfection, 10% brine concentration, soak for about 5 minutes and stir, and then rinse the seeds, which can remove the sclerotinia impurities mixed in the seeds.

2.Land selection and land preparation.

Choose a lot that is convenient for drainage and irrigation and loose and fertile soil, you can use a plow rake to plough the land, rake the soil clods, and plough at least 20 cm through fine tillage. The loose and breathable soil is conducive to the germination and respiration of seeds.

3.Carry out seeding.

After ploughing the land, wait 2-3 days before sowing, dig a few small ditches in the field, sprinkle rapeseed on the slope of the ditch, and cover the soil after sowing the seeds. A centimeter-thick layer of soil is sufficient, and after the soil layer is over, it will restrict the respiration of the seeds, making it difficult to break the soil. Properly sprinkle water on the soil slope, water in a small ditch, and sprinkle water lightly to avoid direct flushing to wash out the seeds.

You can choose how to sow the seeds according to the rapeseed you want to plant. If you want to grow some side dishes, you can grow them according to your preference. Whether it is sown slowly or stripped, all seeds are covered with five times the amount of soil, and the amount of soil is sufficient.

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.

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. The choice of seeds, if there is a place to sell rapeseed seeds, it is best to buy them locally, or you can go to the store with good sales and high comprehensive evaluation to buy online, so that the quality of seeds will be relatively guaranteed.

2. Germination and awakening, the seeds of rapeseed are very small, and it is easy to mix with impurities, so it is necessary to remove impurities first and then carry out germination, the germination method is relatively simple, just soak the rapeseed seeds in warm water at about 30 degrees for 5 hours, and then take out the seeds and put them in a warm place, when 50% of the seeds are exposed, you can sow seeds.

3. Choose the planting soil, rapeseed likes light, so it is best to choose a sunny place to sow seeds, and level the soil deeply before sowing.

4. Seeding method and management, the depth of sowing should not be too deep, keep it at 1-2 cm, and pay attention to the thickness of the covering soil should not exceed 3 cm. After sowing is completed, the growth of rapeseed should be observed to strengthen the prevention of pests and diseases.

5. Rapeseed is generally sown in spring and autumn, due to the difference in climate and temperature between various regions, resulting in different sowing seasons of rapeseed, so rapeseed can be divided into winter rape and spring rape.
