Tomatoes don't grow. What's going on?

Growing tomatoes often encounters various problems, but the most troublesome thing for growers is that tomatoes do not grow and fruits are very small. This directly affects economic value and efficiency. And it's hard to think of any cause other than malnutrition, which is often the result of fertilizer. In fact, tomatoes do not grow a lot of reasons, not just nutritional deficiencies. Let's find out more about it together.

1. Soil fertility

Loam soil is the best, sandy loam medium, but sandy soil fertilizer and water loss is easy, and finally will lead to soil fertility loss. So planting can use loam soil, sandy loam soil, do not use sandy soil, if there is no more land, you can improve the soil, add humus soil, loam soil. Insufficient soil fertility can lead to no growth.

2. Improper fertilization

Tomato fruit color conversion period is mainly the use of low nitrogen fertilizer, high potassium fertilizer, the chlorophyll contained in the fruit to the decomposition of the drug, but not decomposed, because the use of too much nitrogen fertilizer, so chlorophyll does not decompose, not into lycopene. Potassium deficiency will also affect photosynthesis will decline, affect color, metabolism is very slow, affect color. It is best to use a water-soluble fertilizer with high potassium content. Potassium should be used twice as often as nitrogen. Can also root topdressing, spray potassium dihydrogen phosphate to supplement potassium.

3. Low temperature in the shed

If it is winter anti-season greenhouse cultivation, because the outside temperature is too low, it will affect the internal temperature. Can't often ventilate, the air is not good, winter sunshine is not strong. The fruit does not grow easily after fruiting and grows slowly. In this regard, it is best to maintain more than 25 degrees during the day and more than 15 degrees at night, and electricity is needed to warm up. Open the skylight properly on sunny days.

4. Uneven growth

It may be that nutritional growth and reproductive growth are unbalanced, for example, when bearing fruit, but the branches and leaves are too long, too exuberant, so that too much nutrition is consumed, the nutrition of the result is insufficient, and the competition cannot exceed the branches and leaves, which will lead to very small fruits. In this case, the main vine needs to be picked, the branches thinned, some weak branches pruned, and the branches without fruit. This growth may be a lot better, the result is too much, you can properly remove some.

Tomato fruit after growth is not big, slow growth, not obvious, mostly because of malnutrition, insufficient fertility, improper fertilization. There are also special circumstances affecting.
