Pay attention to the adjustment of vegetable types, vegetable production, according to different consumer groups, different consumption habits, different consumer areas of different requirements for products, accurately do market research and positioning, grasp the direction of the development of the vegetable industry. According to the seasonality of different vegetable types (the ratio of off-season to peak season), different uses (fresh food, processing, special) and regional layout, it is necessary to select the corresponding vegetable types and varieties according to the local natural conditions and target market.
The variety of vegetables is extremely rich. With the improvement of living standards, the proportion of “home-cooked dishes†in consumption has been declining in the past, while the proportion of so-called “special dishes†is increasing, so the difference between vegetable types and quality is increasing. Need to pay attention to production.
Pay attention to the selection of disease-resistant varieties, and correctly understanding disease-resistant diseases is always one of the main reasons for the reduction of vegetables. The selection of disease-resistant varieties is an important way to produce high yields and stabilize production, reduce production costs and reduce pesticides and other environmental pollution. Disease-resistant varieties are often only resistant to one or several major diseases. Producers should pay attention to selecting new varieties that are resistant to major local vegetable diseases when selecting varieties. When introducing new varieties from areas with large ecological differences, attention should be paid 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 easy to lose.
Pay attention to the selection of new varieties with good quality. Nowadays, consumers are paying more and more attention to the quality of vegetables. High-quality vegetable products are more easily accepted by consumers even if the price is slightly higher. Therefore, producers should pay attention to the selection of new varieties with good commercial traits, high nutritional value, and even certain health effects.
According to different cultivation seasons, the selection of suitable varieties of vegetables can be produced in a variety of ways, and the corresponding varieties are also very rich. Some vegetables are cultivated in different seasons. The requirements for varieties are very strict. If the varieties are selected incorrectly, the production will be large. Loss.
For example, in early Spring, cultivation of Chinese cabbage, radish, etc., should choose early maturity, strong anti-twitching ability, strong disease resistance, early low temperature tolerance, late high temperature resistant spring cabbage, spring radish type; summer cultivated Chinese cabbage, radish should choose resistant Special varieties with strong heat, antiviral diseases and other major diseases, and attention should be paid to controlling the sowing date. Early spring cultivation of broccoli should choose mid-maturing or late-maturing spring ecotypes. If you choose early maturing varieties, there will be “early flowering†phenomenon; in autumn, you should choose early-ripening autumn ecotypes. If you choose spring ecological varieties, it will cause the flower balls to appear late or even without flower balls.
According to the target market of vegetable products, the corresponding varieties of different regions and different vegetable consumers are selected, which have different consumption habits and different requirements for the commercial characteristics 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 round eggplant type, but in the Yangtze River basin. Most prefer the long eggplant type. The selection of export vegetable varieties for export vegetables has higher requirements for commerciality and safety, and most of them use special varieties. Such as the export of tomatoes generally choose hard fruit type. The fruit size is medium fruit type and the red fruit is more. Soft-fruit tomatoes cultivated in China are not resistant to storage and transportation and cannot be used for export. In addition, the onions and green onions used for export have strict requirements in terms of spherical shape and hardness, and special varieties should be selected.
