Dog days of greenhouse vegetable greenhouses also need frequent management

Dog days are the solar term with the longest period of daylight. Entering the flood season, the rain increases. All kinds of crops grow strongly, weeds, pests rapidly grow and spread, this time the greenhouse in fine management at the same time, but also timely harvest, greenhouse greenhouse planting tomatoes, cucumbers, eggplant and other vegetables have reached the harvest period, plants grow rapidly, transpiration, water demand, management is related to the yield and quality.

First, adjust the appropriate growth environment

Temperature According to different crops and weather conditions to adjust the appropriate crop growth room temperature.

Humidity For the same warm-like fruits and vegetables, the air humidity requirements are also different. Tomato, eggplant like dry growth environment, suitable humidity of 45%~60%. Reducing the air humidity through ventilation and drainage, reducing the amount of watering and other measures, not only to ensure the normal growth of crops, but also to prevent the epidemic of diseases and pests.

2. Timely harvesting

Late harvest not only affects the fruit and plant growth, but also reduces the quality. Try to harvest in the morning on a sunny day, the quality and taste of the products are better than other times.

Third, arrange the plants in time

Cutting leaves removes old leaves, yellow leaves, diseased leaves and lateral branches in the lower part of the plant to facilitate ventilation and light transmission and reduce nutrient consumption.

Four, thinning fruit

The excessive flowers and fruits on the tomato plant are dispersed as soon as possible, and the deformed fruits and the too large and too small fruits on each ear are dispersed as soon as possible, so as to achieve the effect of regular fruit shape, uniform fruit and high commodity rate.

Fifth, scientific watering and fertilization

Scientific watering should be carried out according to the weather, crop growth and soil moisture. It is better to pour small water frequently, and tomatoes and eggplants are generally watered once every 5 to 8 days. Water cucumbers once every 3 days to avoid excessive drought and over-watering at one time. Generally, topdressing is stopped 30 days before pulling rice seedlings, and foliar spraying can be taken to quickly supplement nutrition.
