In production, good beet varieties should have the following characteristics:
1. Excellent economic traits. With higher tuber yield and higher sugar content, both cannot be neglected. In the production of high-yield high sugar varieties, but according to the characteristics of the sugar beet cultivation area and sugar plant requirements, you can also use other types of varieties.
2. Strong resistance to disease and stress. It is resistant to diseases such as brown spot, yellowing virus, root rot, powdery mildew, and nematode diseases. Stress resistance includes drought resistance, cold resistance, moisture resistance, salt and alkali resistance, and resistance to early bolting. According to local characteristics, select some species with some resistance.
3. Widely adaptable. Suitable for different natural conditions and cultivation techniques.
4. Good processing quality. Sugar beet roots contain more sucrose content and less sugar content in the sugar production process.
5. Suitable for mechanical cultivation. With the increase in the area of ​​transplanting of sugar beet mechanical cultivation and paper tube nursery, the requirement for single-embryonic type varieties has increased significantly. To facilitate mechanical picking up of sugar beet, the varieties with slightly larger roots and shorter roots can be selected. Our province can choose sweet research 302,303,304,305 polyploid seed, both high yield and high sugar.
So, how to choose a good breed?
1. According to the amount of sugar produced per mu, taking into account the income of farmers and the benefits of sugar factories, the sugar content of the varieties meets the requirements for sugar production. At present, sugar beets are generally purchased by quality, that is, based on the sugar content of 16%, the higher ones increase their prices, while the lower ones reduce their prices. However, the high sugar content in tuber roots and the low production yields cannot affect the variety of farmers' income.
2. According to the local natural conditions and cultivation techniques, and pay attention to all kinds of mix. For areas with good water and fertilizer conditions, high cultivation levels, and long frost-free periods, polyploid varieties or high-yield varieties should be selected. In regions where the frost-free period is short, the standard high-sugar type varieties should be selected. In the same area, it is not appropriate to use one type of species or even one variety in order to exert natural conditions on the interaction of varieties or meet the processing requirements of sugar mills.
