1. Temperature: it is heat-resistant and cold-resistant, so it is not suitable for planting in the north. Most of the areas are in the southwest. If the maintenance temperature is above 20 ℃, it can grow normally.
2. Watering: it likes to be wet, especially in the development period, it needs a lot of water. When the temperature is high, it needs to be watered once every two days. When the temperature is low, it needs to be watered twice or three times a week. As a result, it needs to control watering later, so as to promote the growth of pods.
3. Fertilization: it consumes nutrients faster, especially in the growth period. In addition to the base fertilizer used in the soil before planting, it needs to be fertilized three to four times in the whole growth period. For the fertilizer type, it needs to use the fertilizer with comprehensive fertilizer effect, and it can also use human and animal dung and urine. When applying fertilizer, it should be noted that the fertilizer cannot contact the plant directly, or the plant will be burned.
4. Light: it is a long sunshine plant, which has a very large demand for light, so it can receive sunshine all day. If it's potted plants, it's best to keep them in the sunny place, and keep them in the sunshine for more than six hours every day.
1. Propagation: rape can be propagated by sowing. Because the germination rate is relatively low under the seed comparison, the medium with high quality shall be selected, and the maintenance environment shall be well adjusted, so as to improve the germination rate. If the seeds are sown in the open field, the row spacing shall be controlled at about 20cm. After the sowing is completed, the fine soil with a thickness of 1cm shall be covered, and the seeds can germinate in about a week by pouring water once.
2. Change basin: if the family maintains in, it needs to change basin every year. When changing basin, it needs to prune the rotten and dry root strips. The soil should use the soil with good drainage and sufficient nutrients.
1. Insect damage: rape is relatively easy to infect aphids. Aphids will attach to the top of each branch and eat the young leaves of the plant, which will affect the health of the plant. At this time, it needs to use Omethoate to spray it.
2. Disease: rape is easy to be infected with Sclerotinia at flowering and fruiting stage. After infection, the leaves of the plant will turn yellow, which will directly affect the yield. When it is maintained at ordinary times, it is necessary to do a good job of prevention and control. You can use dimethoate emulsion to soak and spray for prevention.
1. Edible: it can be eaten, and rapeseed can be pressed.
2. Toxicity: non toxic.
