Rapeseed is rich in minerals and vitamins, including protein, fat, sugar, dietary fiber, calcium, phosphorus, iron, carotene, vitamin B1, vitamin B2, niacin, vitamin C and so on. The content of calcium is high, which is almost equal to 2~3 times of the content of Bailey. Regular consumption can promote skin cell metabolism, prevent skin roughness and pigmentation, and enhance the body's immunity. Planting skills Sunshine: Rapeseed like a cold environment, not resistant to high temperatures, some varieties are more resistant to cold, generally 20-40 days after sowing can be harvested. If you prefer a half-sunlight environment, if the light is too weak, it may cause the plants to grow long and the leaves to be narrow. Selection of pots: You can choose a large square plastic basin, be sure to breathe to avoid rotten roots, the depth of 20 cm. Soil: Like the more fertile loam, you can mix the garden soil and the humus soil in a ratio of 2:1, and add the appropriate decomposed cake fertilizer as the base fertilizer. Pest control: common diseases and insect pests include black-faced disease and cabbage caterpillar, black mold can spray 70% mancozeb wettable powder 500 times liquid, spray once every 6-8 days, a total of 2-3 times; The worm can be sprayed with BT emulsifiable concentrate or 500-800 times of the larvae. Daily maintenance The rapeseed mainly has three cultivation periods in spring, summer, autumn and winter, and different varieties of canola seed cultivation can be selected in different seasons. In order to improve the seed germination rate and prevent pests and diseases, rapeseed should be soaked before seeding. This method is called "soaking". Specifically, the seeds are poured into warm water of 40-50 degrees Celsius, and then the water is continuously stirred by wooden sticks or chopsticks. When the water temperature drops to 20 degrees Celsius, the stirring is stopped, and the seeds are soaked for 2 hours. After the soaking was completed, the water was controlled, and the seeds were immersed for 20 minutes with a potassium permanganate solution having a concentration of 0.5% for disinfection. After disinfection, wash off the disinfectant with water. The seeds are then poured into the soaked white gauze for germination, and can be sown at a temperature of 20 degrees Celsius for one day. Spread the soaked seeds evenly on the surface of the soil and cover the 1 cm thick nutrient soil. Before the germination, the soil can be moistened by spraying. Generally, it can be germinated after 2-3 days, and the true leaves can be grown in 6-7 days. At this time, the first seedling can be carried out, and the plants with poor growth are removed, leaving the seedlings strong. of. When 3-4 true leaves are grown, they can be cultivated.
