Key points of management techniques for cucumber planting in greenhouses in June

June is the beginning of summer. As the temperature continues to rise, if you do not pay attention to ventilation, the temperature in the cucumber greenhouse will often reach above 40 °C, resulting in poor growth of cucumbers, and even symptoms such as sunburn and poor flower bud differentiation, seriously endangering cucumbers. Yield and quality of cultivation. Therefore, in June, it is very important to do a good job in the management of greenhouse cucumbers. The main points of management techniques for cucumber planting in greenhouses in June are now introduced as follows.

1. Timely addition of cooling measures

When the sun is too strong, the temperature in the shed exceeds 30°C, and the cooling effect cannot be achieved by venting, it is necessary to take cooling measures in time, such as setting up shading nets outside the shed, splashing mud, spraying cooling agents, etc., which can be effective. cooling effect. At the same time, we remind vegetable farmers that when using sunshade nets, they should be put away in time at four o'clock in the afternoon and on cloudy days, so as not to affect photosynthesis.

Second, try to pick as little as possible the lower leaves of the plant

Generally speaking, when the vines are falling in winter, it is required to thin the lower leaves, especially the old leaves and yellow leaves, because the humidity in the shed is high in winter, and the disease resistance of the old leaves is weak. Old leaves invade. In summer, except for heavy rain, the greenhouse is ventilated almost day and night, and the humidity in the greenhouse is low. It is recommended not to remove all the lower leaves. These old leaves can block the strong light and play a shading role, which can effectively prevent the ground temperature from rapidly increasing. rise.

3. Watering should be frequent and small

In summer, the amount of water evaporation is large. Many vegetable farmers think that flooding is enough. In fact, it is easy to damage the root system. It is recommended to use small water frequently, which can not only meet the water demand of crops, but also reduce the temperature of the greenhouse. Special reminder, do not water at noon on a sunny day, otherwise it is easy to cause the rhizosphere soil temperature to drop suddenly and cause the plants to wilt or even die.

Fourth, it is very important to nourish the roots and adjust the soil

Cucumber also needs the root system to absorb more nutrients during the fruiting period, so it is very important to nourish the roots and adjust the soil. After the first cucumber picking, top dressing should be applied to supplement nutrients, and the root environment should be conditioned to promote root growth. In the late stage of the harvest period, top dressing can be carried out in combination with spraying.

In summer, doing a good job in the management of cucumbers in greenhouses is the key to ensuring the yield and benefits of cucumber planting, which needs to be paid attention to. The above introduces the key points of management technology for cucumber planting in greenhouses in June, I hope it can be helpful to everyone!
