Temperature: The temperature of rapeseed should be controlled at about 20 degrees; Watering: Watering is required every other day during the flowering period, and once a week during the fruiting period; Fertilization: During the growth period, fertilize two to three times a month. Fertilizers should use compound fertilizers with relatively comprehensive nutrients, and try not to use fertilizers that only contain a single nutrient element; Lighting: The lighting time should not be less than six hours a day.

1. Maintenance methods

1. Maintenance method

1. Temperature: It is heat-resistant but not cold-resistant, so it is not suitable for planting in the north. Most of its distribution areas are in the southwest. The maintenance temperature must be above 20 degrees. , it can grow normally.

2. Watering: It likes moisture, especially during its growth period. It needs a lot of water. When the temperature is relatively high, it needs to be watered once every two days. When the temperature is relatively low, it needs to be watered once a week. Two to three times, watering should be controlled after fruiting, in order to promote the growth of fruit pods.

3. Fertilization: It consumes nutrients quickly, especially during the growth period. In addition to the base fertilizer used in the soil before planting, fertilization needs to be applied three to four times throughout the growth period. Fertilizer seeds should use fertilizers with high efficiency. For more comprehensive fertilizers, human and animal excrement can also be used. When applying fertilizer, be careful that the fertilizer cannot directly contact the plant, otherwise the plant will be burned.

4. Light: It is a long-day plant and has a very high demand for light, allowing it to receive sunlight throughout the day. If it is a plant maintained in a pot, it is best to place it in a sunny place for maintenance, and ensure that the lighting time is more than six hours a day.

2. Breeding skills

1. Reproduction: Rapeseed can be reproduced by sowing. Because the germination rate of seeds is relatively low, it is necessary to choose a relatively high-quality medium and adjust the maintenance environment to increase the germination rate. If sowing in the open field, the row spacing should be controlled at about 20 centimeters. After sowing is completed After that, cover it with 1cm thick fine soil, water it once and it will sprout in about a week.

2. Repotting: If you maintain it at home, you need to repot it every year. When repotting, you need to trim off the rotten and dry roots, and use soil with good drainage and sufficient nutrients.

3. Problem diagnosis

1. Insect damage: Rapeseed is more susceptible to 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. It is healthy. At this time, you need to use omethoate to treat it by spraying it.

2. Disease: Rapeseed is more susceptible to Sclerotinia sclerotiorum during the flowering and fruiting stages. After infection, the leaves of the plant will turn yellow, which will directly affect the yield. During daily maintenance, it is necessary to do a good job For prevention and treatment, dimethoate emulsion can be used for soaking and spraying.

IV. Other issues

1. Edible: It is edible, and rapeseed can be pressed for oil.

2. Toxicity: non-toxic.
