The summer management of cyclamen

The summer management of cyclamen is the biggest technical difficulty of cultivation species, and it enters the high temperature season from June to September in summer. At this time, cyclamen is easy to enter the dormancy period, the fight against adversity is weakened, and the outbreak of diseases and insect pests is frequent, so the success or failure of summer management is directly related to the growth of cyclamen.

The stress resistance of the plant decreased sharply in summer, which was mainly shown as follows:

Second, the ability to resist salt and drought is declining.

The temperature is high in summer, and the fertilizer suitable for cyclamen growth has just been applied. Due to a large amount of water loss of the plant at noon, the EC value in the soil increased sharply and quickly exceeded the maximum tolerance value, thus causing great damage to cyclamen. Therefore, during the summer, the concentration of fertilizer can be halved, but the frequency of fertilization can be doubled.

Countermeasures for cyclamen to pass the summer

Create a suitable environment

Considering the teacher-student environment of cyclamen, most of the wild cyclamen grow low in the shade of the trees in the mountains, on a semi-shady slope. Therefore, it is best to create a good living environment for it.

In general, temperatures above 30 ℃ and light above 40, 000 LUX can cause damage to cyclamen.

Proper shading

For shading, you only need to pull up two layers of sunshade net to meet the requirements, but when the light is not strong, it must be opened in time, which is conducive to ground cooling and ventilation. Shading should not be too overcast, otherwise cyclamen is easy to grow in vain and the resistance is weakened.

Spray cooling

There are many ways to cool down, one of which is this, but be sure to keep the sunshade net at a certain height from the plastic film and cannot be covered directly. In addition, mist and rain are also very good methods.

However, the negative effects brought by the use of water evaporation and cooling can not be ignored. The continuous increase of air humidity in the greenhouse makes cyclamen facing the threat of disease outbreak, so it is particularly important to strengthen ventilation and do a good job in the prevention and control of diseases and insect pests.
