The selection principle of tomato varieties in winter and spring

1. In order to catch up, the early maturity of the variety is preferred. According to the author's forecast and exchanges with peers, vegetable farmers, etc., judging in the spring of next year will not be too good. Under such circumstances, the early maturing of varieties will be more important in this pass.

2. To select large fruit varieties, many varieties of prunes slow at low temperatures, leading to the first panicle or even the second panicle small, this will lead to a certain amount of time in the early good market without a certain amount of production.

3. Must take into account a certain taste, because the early spring tomato market, the variety of fruit is relatively small, and tomato in many areas have a habit of eating, serving as fruit.

In addition, the price difference between tomato prices before and after this spring is not significant, and even late prices are better. Remember that this is a special case that is not encountered for many years. Don't be lucky, deliberately late sowing, or late-maturing varieties.

4. Consider disease resistance. Anti-nematode cultivars are now very mature. If wired worms are found in the field, they can safely choose the anti-nematode cultivars of regular manufacturers, which can save the cost and effort of using nematodes. At present, the tomato-prone diseases such as gray mold and epidemic disease have not been included in the breeding session so far. Therefore, these two diseases should be controlled as a means. Don't listen to the propaganda of some irregular manufacturers and miss the timing of prevention and control. Spring does not usually have TY virus, so this season can not have too much to consider the impact of TY virus. Http://
