Broccoli is rich in vitamin C and has anti-cancer effect, and its efficacy has been recognized by people all over the world. The average nutritional value and disease prevention effect of broccoli far exceed that of other vegetables.

1. Soil preparation and fertilization

Broccoli should be fertilized with sufficient base fertilizer before planting to ensure that there is no shortage of fertilizer throughout its growth cycle. The ridge planting method should be adopted in the planting method. Careful vegetable friends will find that the radish and cabbage planted in the second half of the year are all ridged. The reason why this method is adopted is that the vegetables are planted on the ridge because of drainage. It is rainy in the summer, and it is easy to drown the seedlings if the drainage is not smooth.

2. Sowing and emergence of seedlings

In a good ridge, draw a small ditch about 1CM depth, and then pour water in the ditch. When the water is almost permeable, sow the seeds in the ditch. The seeds can be properly dense, and the seedlings can be interspersed in the later stage according to the emergence situation. Finally, cover the seeds with a layer of fine soil about 1CM thick. Broccoli can sprout in about 5 days.

III. Field management

When the broccoli is full of seedlings, it is necessary to carry out the seedlings for the first time, and remove the seedlings crowded together. If there is a place where there are very few seedlings, they need to be replenished. After that, the seedlings should be carried out every few days, and the final distance between seedlings should be controlled at about 30CM. In addition, weeding broccoli is often carried out.

IV. Management of flowering period

When broccoli grows to about 10 leaves, it begins to bloom. At this time, it is necessary to strengthen fertilizer management and apply it with uniform fertilizers of nitrogen, phosphorus and potassium, but be careful not to water too thoroughly at this time, so as to avoid rotting roots and dead seedlings.

5. Harvest

Broccoli can be harvested when it grows to about 25 centimeters in diameter, but be careful not to harvest it too late, so as not to affect the taste of the flowers.
