At present, the market's demand for vegetables is gradually changing from a quantity type to a quality type. Growers must choose varieties scientifically and rely on technology to improve quality in order to enhance the market competitiveness of vegetable products. How to choose vegetable varieties? Yan Congsheng, an expert from the Institute of Horticulture of the Provincial Academy of Agricultural Sciences, gives you some suggestions. Pay attention to the adjustment of vegetable types. Vegetable production should accurately conduct market surveys and positioning according to different consumer groups, different consumption habits, and different requirements for products in different consumption regions, and grasp the direction of the development of the vegetable industry. According to the seasonality of different types of vegetables (the ratio of off-season to peak season), different uses (fresh food, processing, special purpose), regional layout, especially according to the natural conditions and target markets of various places, select the corresponding vegetable types and varieties. It is also necessary to establish the awareness of species renewal and make full use of the latest scientific and technological achievements. Pay attention to the selection of disease-resistant vegetable varieties. Selecting disease-resistant varieties is an important way for high and stable yields, but a disease-resistant variety is often only resistant to one or a few major diseases. When selecting varieties, producers should pay attention to choosing new varieties that are resistant to major local vegetable diseases. Choose different varieties in different seasons. Some vegetables are cultivated in different seasons with strict requirements on varieties. For example, early spring and off-season cultivation of Chinese cabbage, radish, etc., should choose early maturity, strong bolting resistance, strong disease resistance, low temperature resistance in the early period, and high temperature resistance in the late spring cabbage and spring radish; summer Chinese cabbage and radish should be selected tolerant Special varieties with strong heat and virus resistance, and attention should be paid to controlling the sowing period. Selection of export vegetable varieties. Exported vegetables have higher requirements for commodity and safety, and most of them use special varieties. For example, export tomatoes generally choose the hard fruit type. The soft-fruit tomatoes commonly cultivated in China are not durable for storage and transportation and cannot be used for export. In addition, onions and scallions used for export have strict requirements in terms of spherical shape and hardness, and special varieties should be selected.
