Rapeseed flower pictures (introduction to morphological characteristics and maintenance methods)

1. Morphological characteristics

1. Stem: The stem is relatively thick, generally hairless, or has a little hair.

2. Leaves: The lower stem leaves are divided in a lyre-shaped pattern, ranging from 18 to 25 cm in length and about 4-8 cm in width. The leaves in the middle and upper parts are ovate-elliptical or rectangular, and the base embraces the stem.

3. Flowers: Usually bloom from March to May. The calyx has 4 segments and is green. There are also 4 petals, bright yellow, obovate.

4. Fruit: The fruiting period is from April to June. The fruit is 2-4 cm long and contains seeds, which are black or dark reddish brown and spherical.

2. Maintenance methods

1. Soil: Rapeseed is not very demanding on the soil. As long as the soil is not too poor, it can grow healthily. Generally, loose and fertile garden soil can be used for cultivation.

2. Watering: Rapeseed flowers need to be watered frequently, especially during and after flowering. The plant needs a lot of water during the flowering period, so it needs to be watered in time. Watering after flowering helps it bear fruit.

3. Fertilization: For rapeseed flowers that grow poorly, you can apply some nitrogen fertilizer in winter. Before flowering, you can apply appropriate potassium fertilizer to improve the plant's disease resistance and increase yield. In addition, you can also apply some phosphorus fertilizer to promote flowering and early maturity.
