The introduction of new vegetable varieties requires attention
The new vegetable varieties are well received by the majority of vegetable growers for their high yield, excellent quality, strong adaptability, good disease resistance and good economic benefits. When farmers choose to introduce new varieties of vegetables, they should pay attention to the following five aspects: To understand the local consumption needs. Consumer psychology and circulation conditions play a decisive role in introducing new breeds. It is necessary to learn from the variety that no one wants to produce, to sell it, and to erode lessons in the field. The introduction of some new varieties must be prudent, and a small amount of trials can be used to stimulate consumption. After the market is cultivated, it can be widely promoted. To adapt to local conditions. Each new breed is selected from a certain ecological environment and cultivation conditions. It has a certain degree of adaptability. Before planting, growers need to understand in detail the suitability of the species to natural factors such as climate, soil, temperature, humidity, and light, and introduce new varieties from areas with similar natural conditions as much as possible to increase the insurance factor. It is necessary to introduce the matching plant management techniques. The new varieties are very different from the old ones in their adaptability to the environment, botanical traits, growth period, disease resistance, etc. Therefore, they need management methods that are suitable for them. If old methods are used, the superiority of new varieties cannot be fully displayed, and the purpose of introducing new varieties cannot be achieved. We must pay attention to the introduction of new varieties with less investment and quicker results. If the funds are insufficient and the technology is not high, then the varieties with less investment, easy technology, and quick results will be selected. For example, early spring carrots do not need to be built. The technology is simple and the benefits are good. Go to the regular seed department to buy seeds. Regular seed breeding, strong technical distribution, good reputation, and guaranteed seed quality are the preferred targets.
