Why did you cut back on the tomatoes? 3 common problems that farmers should pay attention to in the future in gardening

Many growers say that tomato control can increase production, why after spraying the control agent, the yield is reduced? When the tomato is in full bloom, the interval between each panicle is large, and it is easy to sit still, affecting the growth and yield. There are many reasons for tomato growth, and it is easy to appear unscientific when controlling prosperity, I summarized three common problems, farmers should pay attention to when planting later.

1. When judging whether tomatoes are thriving, they generally depend on the leaf growth, internodal length and growth state. For example, the normal internodal distance of tomatoes is 5 to 10 cm, and when it exceeds 10 cm, it is long. At the seedling stage, the leaves are unfolded layer by layer, and the leaves are large and thick, which is a normal growth trend. Many farmers see that the stem is thin and weak, thinking that the stem is thicker than the growth, in fact, this method is not completely accurate, to judge from the growth of the plant.

2, there are many reasons for tomato growth, such as excessive nitrogen fertilizer, insufficient light, high night temperature, etc., but many farmers find that after tomato growth, they do not find out the reason to change the growth conditions to control prosperity. This is also one of the misunderstandings of many farmers in controlling prosperity, not only the problem of long-term prosperity has not been solved, but there are symptoms of deficiency of vegetarians.

Early spring or summer and autumn stubble planting tomatoes, most of the plants will appear to flourish, we also have to distinguish the reasons, appropriate control of prosperity. For example, when the autumn stubble is planted, the night temperature in the shed is too high, and the air outlet can be opened, and the temperature in the shed is reduced to 7 to 8 ° C to prevent growth. In early spring, when there is little light, increase light, or spray chlorophyll to improve stress resistance and prevent growth. When nitrogen fertilizer is used too much, the fertilization formula should be adjusted to prevent excessive nitrogen fertilizer from growing strongly. If these several situations cannot be controlled, it is necessary to spray the control agent.

3, the time of tomato spray control agent is also very critical, some farmers in the flowering period, see the tomato has a long growth, spray a time to control the potent, there are also some farmers in the tomato slow seedlings after the control of prosperity. According to our planting experience in recent years, it is better to control the prosperity after slowing the seedlings. Many farmers spray the control agent is worried about excessive control of prosperity and the situation of not growing.

Tomatoes control their prosperity after slowing down the seedlings, and they need to spray a small number of times to control the potent, and they cannot control death at one time. For example, when using 25% paclobutrazol control, only 5 grams plus 30 pounds of water are needed, and when the temperature of the overwintering stubble is low, to prevent excessive control of wang, a bucket of water with 3 grams of paclobutrazol. Spray only once to the location of the growth point, so as to prevent excessive control of the situation. In addition, after the tomato is colonized, if the lying down method is used to control the prosperity, it will affect the normal growth of the plant.

In the management process of tomatoes, controlling the prosperity is very critical, determining the final yield and quality. We must also avoid the above three misunderstandings when controlling prosperity, and reasonably control prosperity in order to ensure high tomato yields.
