What are the methods for seed selection and seedling raising of cauliflower?
Cauliflower, also called caihua or broccoli, is cultivated throughout our country. Cauliflower is delicious and nutritious, and because of its unique medicinal value and edible value, it is deeply loved by everyone and often appears on people's dining tables. Many farmers, when planting cauliflower, will choose a suitable variety. So how is cauliflower seed selected? What are the seedling raising methods? Now let's take a look together with the editor.
1. How is cauliflower seed selected?
When planting cauliflower, first choose the cauliflower variety according to the actual local conditions. In some areas, the temperature in early spring is relatively low, cauliflower grows relatively slowly, and later the temperature rises quickly. Therefore, at this time, varieties with good cold resistance and heat resistance and strong adaptability to temperature changes should be selected.
2. What are the seedling raising methods for cauliflower?
1. Seedbed soil seedling raising method. This is the traditional application of the traditional breeding method. This method can be used to prepare beds in situ.
2. Warm seedling raising method. Use transparent protective facilities, such as greenhouses, plastic film, arched sheds, or in the above facilities, increase the indoor temperature in a certain way to raise seedlings. This is an important seedling raising method for winter and spring seedling raising, especially for protected cultivation or open-field cultivation of cauliflower in northern China, for example, using hot beds, which is also a heating facility.
3. Shading breeding method. This is a method of raising seedlings in hot summer, so as to use gauze coverings or awnings to cool and moisturize, promote seedling growth, or prevent the occurrence of viruses and other pests and diseases.
4. Cutting seedling method. This is a method of applying some cauliflower vegetative organs such as side branches, leaves, etc. after appropriate treatment to promote the development of seedlings. At present, cauliflower leaves are used for cutting propagation, and the seedling rate can reach more than 80%. After cutting, the plants have stronger disease resistance, and the offspring are more genetically stable.
5. Test tube seedling raising method. This is a method of culturing seedlings in an artificial medium, in test tubes and flasks under artificially controlled conditions. The Vegetable and Flower Research Institute of the Tianjin Academy of Agricultural Sciences successfully induced seedlings from cauliflower flower stalk stems and curd stems using tissue culture.
The above is the introduction to cauliflower. For cauliflower seedling raising, due to different sowing seasons, the seedling raising methods are also different. In the south, according to past planting experience, cauliflower is mainly raised in protected areas, and this can be divided into two methods: shaded seedling raising and cold bed seedling raising. Only by correctly mastering the cauliflower seedling raising method in the appropriate season can it help increase cauliflower yield.
