Planting time and method of Tomato

Tomato can be planted in two seasons, generally in March and June in Northeast and Northwest China, January-February in North China, and March and August in other areas. Planting method: select high quality varieties, planting quantity is about 600plants per mu, row spacing is 40-50cm, plant spacing is 30-40cm, urea, potash fertilizer, phosphate fertilizer and so on can be applied during growth period. When side branches grow too much, they should be pruned. Scientific management can improve the quality and yield of tomatoes.

1. Planting time of tomatoes

In the northeast and northwest of China, tomatoes can be planted for two seasons, so they can be sown in March and June every year, while in North China, they usually start sowing in January-February every year, but except for the above areas, tomatoes are basically planted in March and August every year.

Second, the planting method of tomato

1. Select varieties

At present, there are many varieties of tomatoes on the market, and different varieties have different tastes. Some have good taste and bright appearance, and of course some are of poor quality. It is all because different varieties are planted in different areas, and their quality will also change. Therefore, we should plant them according to the conditions of the region. For example, in Hunan, we can choose varieties with strong drought resistance and disease resistance.

2. Reasonable density

(1) the output of fruits, vegetables, medicinal herbs and crops will all be related to planting density, so it is necessary to carry out reasonable close planting according to the selected varieties and the degree of fertility of the planting land. under normal circumstances, 500-600 seedlings can be planted per mu, but in relatively barren plots, planting can be appropriately increased, while the land with abundant fertility can be appropriately reduced.

(2) the distance of each row is generally between 40-50cm, and the distance of each plant is about 30-40cm, which is convenient for field management in the later stage, and there is enough space to stretch among tomato plants, which is beneficial to photosynthesis.

3. Scientific fertilization

The main results are as follows: (1) after applying sufficient basic fertilizer, tomato needs to be fertilized many times in the later growth stage, the first time is after planting, urea can be applied to promote seedling growth, and when the tomato enters the flowering stage, the second fertilization should be carried out, during which potash fertilizer and phosphate fertilizer are mainly applied, which is beneficial to promote flowering and protect fruit.

(2) the third fertilization is after the tomato fruit is set, and it can be fertilized many times, because the tomato can be picked in batches, so after each picking, it is necessary to spray a little foliar fertilizer, which is conducive to strong fruit and promote fruit ripening.

4. Pruning and pruning

The main results are as follows: (1) during the growth of tomato, many people think that if there are more side branches, the fruiting rate will be higher. in fact, on the contrary, if there are too many side branches, the more nutrients the plant consumes. Although there are a lot of tomatoes in the later stage, the number of high-quality tomatoes is very small.

(2) therefore, it is necessary to prune all the excess branches and leaves, keep only the trunk and some side branches, and then remove the overgrown leaves in the fruiting branches, which is beneficial to the absorption of nutrients and photosynthesis of the plants. at the same time, the permeability of the countryside will be better, but also can prevent the occurrence of diseases and pests.
