What about the latest tomatoes?

Tomatoes are widely planted, and there will be a variety of problems in planting, which will affect the yield and quality of tomatoes, while many vegetable farmers report that their tomatoes are not growing up and can not find a solution. So what should we do if tomatoes don't grow up? Come and have a look with the editor.

First, the reason why tomatoes don't grow up.

1. Variety

Some varieties have a small difference in fruit size, and some varieties are suitable for long-term harvest, which can produce up to 17-20 fruits, and this handful of seeds is more expensive. In common varieties, each fruit is smaller than the previous one, and the more the top fruit is, the smaller the fruit is. This kind of fruit is more suitable for cultivation with a short harvest period, generally bearing 3-4 sets of fruit, followed by pinching, leaving 3-4 fruits per ear.

2. Fertilizer

The lack of various growth elements in plants will cause the fruit to become smaller, and the lack of magnesium, manganese and boron will also affect the size of the fruit. In addition, improper fertilization will also affect the size of the fruit. For example, too much frequent application of diammonium, resulting in phosphorus poisoning, the fruit will become smaller; one application of potash fertilizer will also cause a reduction in yield; if there is too much boron fertilizer in the greenhouse, it will also make the fruit smaller.

3. Cultivation

Improper cultivation and management will also cause tomatoes not to grow up, for example, there is no frame, resulting in plant lodging; in addition, the soil is dry and lack of water, and the fruit can not expand normally. Another point is auxin poisoning. At this time, the most common reason why the fruit becomes smaller in the greenhouse is that the auxin accumulates a little bit without each layer of flower, and the fruit is affected after three or four fruits. therefore, gibberellin is used to correct every 3-4 fruits.

II. Solutions

Before planting in the greenhouse to flowering, the plant growth is small, the demand for nitrogen fertilizer is low, and the nitrogen fertilizer in the base fertilizer can fully meet the plant growth, so there is no need for nitrogen fertilizer at this stage. Entering the flowering and fruiting period, as the temperature picks up, the growth rate accelerates and the growth increases, so it is necessary to apply nitrogen fertilizer in time to ensure nutrient supply. From the first ear blooming, 20-25 kg of nitrogen fertilizer can be applied per mu, combined with potash fertilizer, to ensure the normal growth of tomatoes. In the later stage, the temperature gradually increased and the evaporation was large, and the watering interval gradually became shorter, so the nitrogen fertilizer applied each time could not be too much to reduce the nitrogen fertilizer loss with water.
