There are many temperatures and high temperatures. If you want to plant more cucumbers, farmers cannot ignore 2 aspects in gardening

 

In the greenhouse, the summer cucumber began to plant seedlings, and the same method of substrate cultivation was used. Some farmers and friends have questioned that there are many problems in planting cucumbers during high temperatures, such as heavy problems, high temperatures, etc. How should these aspects be avoided?

 

  1. Cucumber can be cultivated in substrate to avoid the problem of repeated stubble. When many friends see the substrate cultivation, the change speed is very fast, and the seedlings are planted the next day after the plucking. Will this affect the next growth?

In soilless culture, the substrate and planting tank can continue to be used, but only after a simple treatment. If planted directly, the root system and fertilizer remaining in the substrate will affect the growth of melon seedlings. Therefore, after the last plucking, drip irrigation should be carried out to rinse the impurities and salt, or the fungicide can be washed again. When planting seedlings, it is the same as the new substrate, and the substrate is relatively loose. It is also very convenient to plant seedlings, so there is no need to dig holes.

 

After the cucumber is planted, only water it. After the seedlings are slow, it is necessary to start fertilizing. Soilless cultivation and fertilization pay attention to the supplement of medium and trace elements, the use of all-element fertilizer, which can prevent the symptoms of deficiency. Therefore, through reasonable water and fertilizer management, the problem of re-emergence of vegetables can also be avoided.

 

 

  1. When planting cucumber in summer, it is faced with adversity problems such as high temperature, dryness and strong light in the shed, which is also a period when many diseases often occur, which is very unfavorable to cucumber growth. High temperature, dry, will affect the root growth of cucumber, root capillary less, water absorption and fertilizer absorption capacity is weak, often appear wilting or flower topping and other physiological diseases.

 

The diseases that cucumber should pay attention to in summer are virus disease, stem rot, powdery mildew and other root diseases, which have a certain relationship with temperature and environmental humidity. It cannot be considered that more drugs can completely prevent and control diseases. It is necessary to control temperature and humidity, reduce the spread of diseases, and comprehensively prevent and control diseases.

 

First, find ways to reduce the temperature in the shed, such as covering the sun shade net, opening all the vents, without mulch or straw cloth. In addition to controlling the water holding capacity of the substrate, it is also necessary to pay attention to the humidity of the air. Below 70%, it can be sprayed properly to cool down and humidify.

 

Second, cucumbers grow poorly under stress, mainly due to weak roots. High temperature and strong light had an effect on root growth. After cucumber colonization, a rooting agent was used to promote root growth. Then use seaweed essence to wash and apply at regular intervals to maintain the root system. Third, fight drugs in advance to prevent large-scale occurrence of diseases.

 

It is said that it is more difficult to plant fruits and vegetables in the summer. We use the soilless culture model to solve the problem of re-cultivation. Field management, pay attention to root maintenance, root growth is strong, is the basis of high yield of cucumber, at the same time, reduce temperature, control humidity, reduce the occurrence of diseases.
