Control methods of loose flower balls in cauliflower

Cauliflower, also known as cauliflower, cauliflower or cauliflower, is a cruciferous vegetable, a variety of cabbage. The head of cauliflower is a white inflorescence, similar to that of broccoli. Cauliflower is rich in vitamin group B and group C. These ingredients are water-soluble and are easily lost by thermal decomposition, so boiled cauliflower is not suitable for high-temperature cooking or boiling. The original Mediterranean coast, its product organs for white, shortened, fat and tender buds, branches, rachis and other polymerization of the flower ball, is a kind of crude fiber content, fresh and tender, rich nutrition, delicious flavor, people like to eat vegetables.

Growth habits of cauliflower

Cauliflower growth habits like cold, is a semi-cold-resistant vegetables, its heat and cold tolerance are not as good as heading cabbage, neither high temperature and drought, nor frost tolerance. The suitable temperature for growth is relatively narrow, and the cultivation requirements for environmental conditions are relatively strict, which is mainly determined by the botanical characteristics of cauliflower. Because the product organ of cauliflower is a short flower branch, flower axis, flower bud and so on, the flower ball is not only a reproductive organ but also a nutrient storage organ.

Biologically speaking, any organism to the reproductive stage is the fragile stage with the worst stress resistance, so cauliflower has poor resistance to adverse environmental conditions such as high temperature, drought and frost during the period of flower head growth and development. In terms of the growth habits of cauliflower, the aggregated bulb is used as a nutrient storage organ. Under suitable environmental conditions, cauliflower changes from vegetative growth to reproductive growth through the process of nutrient accumulation and storage with the bulb as the carrier, so as to make the bulb fully grow and firm. If cauliflower is at this stage, the external conditions are beyond its own suitable range, such as high temperature and drought, the above process will be shortened, and its shortened flower branches will elongate rapidly at high temperature, thus making the heading small and loose, and the cultivation will not get a satisfactory harvest.

Control methods of loose flower balls in cauliflower

Symptoms and causes of loose bulbs in cauliflower: bolts and branches develop rapidly, leading to loose bulbs: reasons for formation:

The main results are as follows: 1) during the heading period, the temperature is too high, the bulb expansion is inhibited, and the flower bolts and branches grow rapidly, which leads to scattered flowers.

2) the bouquet is not harvested in time after it is fully grown.

Prevention and control methods of scattered bulbs of cauliflower

1) sowing at the right time and arranging the flower head growth period in the month when the average daily temperature is 15-23 ℃, so as to avoid the effect of high temperature during the heading period.

2) timely harvest when the bouquet is fully grown, the surface is round and the edge is not yet scattered.
