What if the latest tomatoes can't sit still?

Tomatoes can be used as both fruits and vegetables, which helps to enhance people's physical fitness, clear heat and detoxification, promote metabolism and so on. Although tomatoes are suitable for sowing and growing in summer, they can now be planted in any season through greenhouse cultivation, but there are also some problems, among which tomatoes can not hold flowers and fruits are the main problems. so how to prevent and cure it? Let's take a look at it.

1. Control the temperature of the greenhouse

Tomatoes are temperature-loving crops, so the temperature in the greenhouse should not be too high, not more than 30 degrees during the day. If the temperature exceeds 35 degrees and lasts for more than two hours, then the flower buds of tomatoes will be affected. The temperature at night should not be lower than 12 degrees and higher than 18 degrees. If the temperature is too high at night, the stems of tomatoes will grow excessively, resulting in falling flowers. To carry out artificial cooling, in the high temperature, sunny weather, in the hottest noon to shade the greenhouse, or in the greenhouse [splashing water physical cooling, and so on. If you lower the temperature, you can set the fruit well.

2. Spraying growth regulators

Tomato leaves can be sprayed with zhuangsu and other chemicals to adjust the growth rate of tomatoes, the stalks of tomatoes will be thickened, but can not be overused. A small amount of spray can be used as an experiment before use, and then the corresponding dosage can be made according to the growth of tomatoes. If the dosage is excessive, not only can not promote the growth of tomatoes, but also inhibit the growth of tomatoes. Try to choose to spray on a sunny afternoon, as this can reduce the risk of drug damage.

3. Remove leaves to protect fruit

If it is found that there are more leaves of tomatoes, the better leaves can be removed to protect the growth of tomatoes. However, the number of fruits per plant should not be too large, because if the fruit represents excessive nitrogen fertilizer, excessive nitrogen fertilizer will lead to the imbalance of nutrient absorption of tomatoes. And too much fruit will cause the nutrition to be absorbed by the lower fruit, and the upper fruit does not have enough nutrition to blossom and bear fruit, resulting in the upper fruit falling. During the flowering and fruiting period, we should also pay attention to reasonable fertilization, otherwise it will also cause uneven nutrition.

4. Supplement nutritious elements

It is found that when the tomato grows too fast or the water in the tomato body evaporates rapidly due to the high temperature, the lack of calcium can be sprayed with some foliar fertilizer containing boron, calcium and other trace elements, which can also reduce the drop of flowers and fruit to a certain extent. and in the case of too high temperature can also spray a little bit of anther, which can not only protect flowers, but also increase moisture.

The above four points are the ways to prevent tomatoes from falling flowers and fruits. Tomatoes have higher requirements for temperature, and the latter three points are almost all the sequelae caused by high temperature. Therefore, controlling the temperature around tomatoes and in the greenhouse in the daily management can reduce or avoid the occurrence of falling flowers and fruits.
