2, watering: it likes humidity, especially during the development period, requiring a lot of water. When the temperature is high, it needs to be watered once every two days, and when the temperature is low, it needs to be watered two or three times a week. In this way, watering will be controlled in the future. The purpose is to promote the growth of fruit pods.
3. Fertilization: It consumes nutrients quickly, especially in the growth period. In addition to the base fertilizer used in the soil before planting, it needs to be fertilized three or four times during the whole growth period. Fertilizer seeds should use fertilizers with comprehensive fertilizer efficiency, and human and animal manure can also be used. When applying fertilizer, it should be noted that the fertilizer cannot directly contact the plants, otherwise it will burn the plants.
4. Illumination: It is a long-day plant, which has a great demand for light, so it can accept all-day sunshine. If it is a potted plant, it is best to keep it in a sunny place, and the daily illumination time should be guaranteed to be more than six hours.
Second, breeding skills 1, reproduction: rapeseed can be propagated by sowing. Because the germination rate of seeds is relatively low, it is necessary to choose high-quality culture medium and adjust the maintenance environment, so as to improve the germination rate. If you sow in the open field, the row spacing should be controlled at about 20 cm. After sowing, cover with fine soil with a thickness of 1 cm and water it once, and it will germinate in about a week.
2, change the basin: if the family is taking care of it, change the basin every year. When changing pots, the rotten and dry roots should be trimmed off, and the soil with good drainage and sufficient nutrients should be selected.
Third, the problem diagnosis 1, pests: rape is more susceptible to aphids, aphids will attach to the top of each branch and eat the young leaves of the plant, affecting the health of the plant. At this time, you need to spray omethoate.
2. Disease: Rape is more susceptible to Sclerotinia sclerotiorum at flowering and fruiting stage. After infection, the leaves of plants will turn yellow, which directly affects the yield. When maintaining at ordinary times, it is necessary to do a good job of prevention, and dimethoate emulsion can be used for soaking and spraying prevention.
Four. Other questions 1. Edible: Edible, rapeseed can be used to extract oil.
2, toxicity: non-toxic.
