Five ways to prevent high temperatures in exposed vegetables
In hot summer, vegetables are cultivated in open field, and the damage caused by high temperature is more serious. If we want to protect the benefits, we must take necessary protective measures. 1, small vegetable plots can be set to cool the shady shade. Tops branch, or grass felt. 2. Set up a temporary small shed covering the shade net. When cabbages, celery, broccoli, and cabbage are grown in summer and autumn, it is a hot day when shade must be applied. The vegetable peasants set up temporary small sheds and covered the shade nets outside. This can not only reduce the temperature but also protect the light and prevent heavy rain. 3, the ground covered with thin grass or hay. After irrigating after sowing, the seedbed can be covered with thin grass, hay, etc. to cool and moisten the seedlings. When 60% of the seedlings are unearthed, the cover can be peeled off to allow the seedlings to gradually lengthen the light exposure time to prevent the seedlings from being exposed to the sun and suffer damage. 4, increase the number of leaf blades of the vegetable plant shade. When topping the tomatoes in summer season, two layers of leaves should be kept on top of the top fruit. Upper side branches of pepper vegetables, leaving two leaves and then go to the head, but also in order to play the role of cooling shade. There are summer and midsummer outdoor watermelons in the summer season, and vegetable growers generally use their leafy melon vines to cover the body of the melon, which can also play a role in cooling the shade. 5, irrigation cooling. After irrigation in summer vegetable fields, it is best to cover wheat straw or wheat bran on the surface, or cover a thin layer of dry soil to reduce evaporation of water and reduce ground temperature. In addition, watering takes place in the morning or in the evening. In the event of heavy rain, we must also pay attention to the elimination of water in the field in time, and then use well water to control vegetable fields in order to reduce the temperature. Using spray irrigation method can also reduce the ground temperature and increase the air humidity appropriately.
