The latest methods of protecting flowers and fruits of tomato in summer

High temperature and humidity in summer will affect the normal pollination and fertilization of tomato, which will lead to poor flowering and fruit setting. If the plant grows excessively and the nutrition supply is less, the phenomenon of poor fruit will occur. So how to protect flowers and fruits in summer? Let's get to know it.

1. Supplement boron and calcium

Calcium and boron have great effect on tomato flowering and fruiting, and boron can be supplemented before flowering, that is, boron fertilizer can be applied once before the formation or opening of flowers per panicle, which can not only promote the good differentiation of flower buds, but also avoid the formation of deformed flowers. The appropriate concentration is 500-1000 times. At an interval of about 10 days, after fruit setting, spraying calcium fertilizer once, it is best to choose chelate calcium or lignin calcium, spray 1000-2000 times with water, the effect is better.

2. Reasonable lighting of flowers

When each spike of flowers blooms, there will be 3-4 flowers together, and 2-3 days after the first blooming of each panicle, 4-5 flowers will appear, which is the main point of pointing flowers. It should be mastered to order flowers before blooming, but it should be noted that the concentration of flowers should decrease with the increase of temperature, so as not to form deformed fruit due to excessive concentration of flowers.

3. Control the flowering temperature.

The temperature of the florescence is more important, pay attention to the temperature at 28 degrees during the day, should not exceed 34 degrees, and the night temperature should not exceed 20 degrees. When the temperature is too high, it is recommended to use sunshade net or cooling and cooling treatment, so as to avoid high temperature burns and affect fruit setting. In the midday when the highest temperature can be combined with micro-spray equipment to cool down, but also alleviate the humidity in the shed.

4. Spray to promote flowers

Spraying seaweed or amino acid foliar fertilizer in tomato flowering and fruiting stage can obviously improve the quality of flowers, ensure fruit development, enhance fruit resistance and prevent diseases and insect pests. But pay attention to the concentration, take alginic acid foliar fertilizer as an example, spray 5-1000 times of water, spray 2-3 times continuously, each time interval 7-10 days, promote tomato blossom and bear fruit.

5. Keep the fruit reasonably

After setting the fruit, the same size, similar fruit shape and no diseases and insect pests should be selected according to the demand, and the rest of the fruit should be removed in time to save nutrients and focus on the development of large fruit. For example, the large fruit type tomato leaves about 3 per ear, the small and medium fruit type can stay 4-5, and the deformed fruit should be removed in time.
