Rape flowers bloom from March to April every spring.

Rape flower is a Brassica plant in Cruciferae, and now it is cultivated as an economic crop, mainly concentrated in Wuyuan, Hanzhong basin and Yangtze River basin in Jiangxi Province, with a wide range of uses. The morphological characteristics of rape flowers are that the plants are straight and clustered, the stems are cylindrical, the stems have leaves, usually alternate, the flowers are bisexual, and the petals are arranged in a cross shape.

The habit of rape flower is that it likes light and warm and cool climate, and it is suitable for growing in deep and fertile soil. The flowering period of rape flowers is around March, and the flowering period is as long as 30 days. The flowering time of rape flowers in different areas will be different, and the change of external temperature will also affect the flowering time of rape flowers.

Matters needing attention in planting rape flowers:

1. Proper watering: rape flowers need a lot of water during bolting in spring, so they should be watered in time and combined with fertilization. When watering, the soil must be soaked, but it is not advisable to water it too much.

2, anti-freezing, warm: the climate in spring is changeable, the temperature is unstable, and it may be cold in spring. We must pay attention to prevent freezing injury and pay attention to the weather forecast. Before the cold current strikes, we must take measures to keep warm and keep out the cold. We can cover the rape flowers with a layer of nylon cloth.

3. Rational fertilization: When planting rape flowers in spring, we should pay attention to rational fertilization. When rape flowers appear buds in spring, they begin to change from vegetative growth to reproductive growth. At this time, it is necessary to apply more compound fertilizers rich in nitrogen, phosphorus and potassium, preferably furrowing between rows. Generally, the depth of the border is 10 cm, and the width is 20 cm, so there is no need for acupoint fertilization.
