First, planting time:

Rape flowers are planted in autumn and winter and bloom in spring. However, the climate in different regions is different, so sowing should be carried out according to the suitable planting temperature.

In fact, the requirements for soil are not high, but it is not very good for planting too sticky soil. Turn over the soil before planting, the soil should not be too loose or too hard, and it needs watering before planting. If the soil is wet and has enough water, it can be planted.

Third, planting management:

Rape flowers need to be replenished with water in time during their growth. Early spring is a period of vigorous growth. Spring irrigation should be carried out in spring to restore the frost in winter and supplement the water shortage caused by freezing injury in winter. Irrigation is also needed during flowering and pod setting to promote the vigorous growth of rhizomes.

Secondly, fertilization should be carried out together during irrigation, and about 5 ~ 7 kilograms of urea should be applied per mu of rape flowers. After the rape flower sprouts, it should be topdressing outside the root in time, diluted with boron, phosphorus, manganese or compound organic fertilizer. You can also spray boric acid solution on the leaves to make the rape flowers flourish and bear more fruits.

Also pay attention to the prevention and control of pests and diseases. In the heating stage, bacteria may grow in a humid and sultry environment, so carbendazim solution should be sprayed in time for disinfection. If there are pests, it is necessary to spray pesticides in time to prevent the normal growth of rape flowers from being harmed.
