Hollow preventive measures of strawberry

After strawberry fruit, not all fruits can bear fruit well, sometimes there will be some problems, such as hollow fruit, the fruit appearance is the same as other fruits, the size is normal, and some are still very large. But when you cut the strawberries, you can see that the strawberries are sewn hollow, and the taste is not as good as the normal strawberries. Then today I'm going to introduce to you what the reason is. How to prevent this phenomenon from happening.

I. the cause of the disease

1. Low temperature

The low temperature appeared in the fruit setting period, which affected the growth and developed slowly. After the temperature picks up in the later stage, the growth will accelerate again, and the uneven development will cause cracks and voids.

two。 High temperature and weak light

Flowering time is not good, or continuous high temperature, more than 35 degrees, will affect flowering, flower development, if the rain directly leads to part of the pollen loss of vitality, poor pollination and fertilization, poor fruit growth.

3. Boron deficiency

Plant growth is weak or too late postharvest, nutrient fertilizer and water supply is insufficient or has not been harvested to continue to grow, aging, water loss, nutrient consumption will form a hole. In addition, enough boron is needed to transport nutrients to the fruit, and boron deficiency may cause hollow fruits.

4. Influence of expanding agent and variety

Do not use expansion agent, accelerate the growth is easy to content hollow, after drought water replenishment too much, easy to hollow. Some varieties are hollow easily, such as Xingxiang and so on.

II. Preventive measures

1. Adjust temperature and light

Cultivate in greenhouse or other facilities as far as possible, avoid the low temperature below 10 degrees, and pay attention to adjust the temperature at any time. It is best to maintain the growth temperature of 20 degrees to 25 degrees, not more than 35 degrees, high temperature is easy to affect pollination and fertilization. Flowering period to receive enough light, lack of light is easy to fall flowers, floral organ underdevelopment, affecting the fruit.

two。 Fertilizer control and water control

During flowering and fruiting period, enough boron fertilizer and calcium fertilizer should be sprayed to promote the transport of nutrients to the fruit. Maintain a balanced supply of fertilizer and water at all stages of the growth period. Don't be short of fat and water. In addition, flowers and fruits should be thinned to ensure the concentrated supply of fertilizer and water. Maintain 60% of the soil moisture at ordinary times, 45% of the soil moisture in the flowering period, and more than 65% in the fruiting period. There can be no shortage of water in the later stage of growth.

The above are the specific reasons for the hollow strawberry, and then according to the cause to prevent, adjust the temperature, light, water and fertilizer, nutrition, can prevent the hollow.
