Pay attention to the adjustment of vegetable varieties Vegetable production should be based on different consumer groups, different consumption habits, different consumption requirements for different products, accurately do a good job of market investigation and positioning, and grasp the direction of the development of vegetable industry. According to the seasonality of different types of vegetables (proportion of off-season and high season), different uses (fresh food, processing, special purpose), regional layout, in particular, according to local natural conditions and target markets, select the appropriate vegetable species and varieties.
The variety of vegetables is extremely rich. With the improvement of living standards, the share of the “head of the family†in the consumption has been declining. The proportion of so-called “specialties†has been increasing, and the difference in the types and quality of vegetables has increased. The production needs to pay attention.
Careful selection of disease-resistant varieties and correct understanding of disease-resistance diseases are always one of the main reasons for reducing production of vegetables. Selection of disease-resistant varieties is an important way to increase production, stabilize production, reduce production costs, and reduce pesticides pollution to products and the environment. Disease-resistant varieties are often resistant to only one or a few major diseases. Producers should pay attention to selecting new varieties that are resistant to the main diseases of local vegetables when selecting varieties. When introducing new varieties from regions with large differences in ecological types, we should pay more attention to disease resistance.
At the same time, the same disease-resistant variety cannot be used for a long time, otherwise, the disease resistance of the variety is easily lost.
Pay attention to selecting new varieties with good quality. Nowadays, consumers pay more and more attention to the quality of vegetables. High-quality vegetable products are more easily accepted by consumers even if their prices are slightly higher. Therefore, producers should pay attention to selecting new varieties with good traits, high nutritional value, and even certain health effects.
According to the different cultivation seasons, we can select suitable varieties of vegetables. The production methods are various and the corresponding varieties are also very rich. Some vegetables have very strict requirements on varieties in different seasons. If the variety is wrong, it will make the production bigger. Loss.
Such as early spring off-season cultivation of Chinese cabbage, radish, etc., should choose early precocity, strong anti-convulsant ability, strong disease resistance, early low temperature resistance, late high temperature resistant spring cabbage, spring radish type; summer cultivation of Chinese cabbage, radish should choose resistant Special varieties with strong heat, antiviral and other major diseases, and attention should be paid to controlling the sowing date. Early spring cultivation of broccoli should be done in medium- or late-maturing spring ecotypes. If early-maturing varieties are selected, the phenomenon of "early flowering" will occur; in early autumn, early-maturing autumn eco-types should be selected, and if ecological varieties are selected, it will cause the flower bulbs to appear late, even without flower balls.
According to the target market of vegetable products, the corresponding varieties of different regions and different vegetable consumption people have different consumption habits and have different requirements for the traits of vegetables. When producers organize and arrange vegetable production, they must fully investigate the commodity requirements of the target market, and then select the corresponding varieties. Take eggplant as an example, consumers in North China generally prefer the type of eggplant, and in the Yangtze River basin Mostly like long eggplant type. Selection of Exported Vegetable Varieties Exported vegetables are more demanding in terms of commerciality and safety. Most of them use special varieties. If the export tomato generally choose hard fruit type. The fruit size is medium fruit type, red fruit is more. Soft-fruited tomatoes that are commonly cultivated in China are not resistant to storage and transportation and cannot be used for export. In addition, onions, scallions, etc. used for export have stringent requirements in terms of spherical shape, hardness, etc. Special varieties should be selected.
Scientifically selecting vegetable varieties
At present, the market's demand for vegetables is gradually changing from quantitative to qualitative. Vegetable producers must scientifically select varieties, rely on science and technology, and continuously improve quality and output in order to enhance the competitiveness of vegetable products in the market. The selection of vegetable varieties, in particular, should pay attention to the following nine aspects.
