High temperature season, vegetables fine management to ensure quality.

When the year is high, the hottest summer high temperature is the dog days, and the most important thing is the adjustment and control of the crop growth environment. Growth environment, including temperature, humidity, water and fertilizer, light and management conditions.

1, temperature: such as celery, spinach, Chinese cabbage and other shade-happy vegetables, in the dog days should be appropriate to control the temperature conditions, appropriate to reduce sunlight, so as to avoid excessive soil temperature, intense explosive sun will also lead to vegetable leaves curl burn; Yang vegetables, we do a good job of normal management.

2, light: for shade-loving crops, should cover the sun net to reduce strong light. To avoid strong light burns the leaves, or the light time is too long and delay the normal growth of vegetables.

3, humidity: The dog days belong to the hot and rainy season, the rainfall is large, so we need to dig out a deep ditch in the field land, so that the flow of water is smooth, not to flood vegetables, but also to control the height of the water level, to better achieve the moisture of the soil. After the rainstorm, the water should be drained in time to avoid the water caused by vegetable roots soaking and rotting. Greenhouse planting should be ventilated in time to remove humidity and reduce air humidity.

4, water and fertilizer: promote the integration of water and fertilizer technology, save labor, water and fertilizer. High temperature soil evaporation is large, and the application of micro-irrigation and micro-spray technology in the morning and evening in vegetable fields can play a role in humidification and cooling, improve field microclimate, adjust soil water, fertilizer, gas and heat conditions, effectively reduce the harm of high temperature and drought on vegetable production and promote vegetable growth.

5, light: for shade-loving crops, should cover the sun net to reduce strong light. To avoid strong light burns the leaves, or the light time is too long and delay the normal growth of vegetables.

Solanaceous vegetables should be properly pruned to reduce leaf overlap, thus enhancing photosynthesis. Vine crops, such as cucumbers, grapes, cowpeas, etc., should be set up in time to make the vine normal climbing growth, so as to avoid the vine attached to the ground for a long time and rot.

High temperature weather is the flourishing stage of pests, diseases are more common leaf wilt, soft rot, blight and other diseases, for different crops, different pests and diseases, we should be based on the growth stage of vegetables, disease, insect situation, soil conditions and other factors to consider comprehensive control.

6. Management: Strengthen pest control to ensure product safety. Insect nets, insecticidal lamps, color plates, insect attractors and other measures are used to prevent and control vegetable diseases and insect pests such as Diamond-moths, Streptomyces xanthophora. It is necessary to pay attention to rational and safe drug use, strictly prohibit the use of high-toxic and high-residue pesticides, and do a good job in the safety interval to ensure the quality and safety of vegetable products.
