After the "little heat" enters the midsummer season, the temperature during the day is as high as 30℃, and the suitable growth temperature for ginger is about 25℃. Excessive temperature and light intensity often cause physiological obstacles in ginger. Coupled with the flood season in the north, more rainy weather is likely to cause various diseases to spread. The following introduces the management points of ginger during the midsummer period. 1. Uncover the mulch in time The main function of mulching film is to increase the temperature and protect the moisture in the early stage. After the ginger enters the "three-pronged" period, the main management measures are cooling and watering and fertilization. At this time, the mulching film will not only play a role, but will also bring great disadvantages. . Excessive ground temperature affects the swelling of the ginger block and also affects the root system. The mulch reflects sunlight, which will heat and bake the leaves, which will affect the normal growth of plants. Plastic film mulching affects watering, fertilization and spraying, and brings great inconvenience to field management. Therefore, it is necessary to uncover the mulch in time to promote the growth of ginger. 2. Supply sufficient fertilizer and water After the ginger "triple fork" period, the ginger block enters a rapid expansion period. This period is also a period when ginger requires a large amount of water and fertilizer. The potassium sulfate compound fertilizer should be flushed with water once every 15 days, and the ginger should be flushed 3 times each time. Flushing 30 kg per mu. 3. Prevent diseases early In production, the main leaf diseases of ginger include anthracnose, leaf spot, leaf blight and bacterial diseases, and root diseases include stem rot, root rot, and ginger blast. To prevent and control leaf diseases, you can use 10 ml of Ami Miaoshou + 35 ml of Copper Gao Shang to spray 15 kg of water for prevention and control, and then spray once every 15 days. Using this method to irrigate roots can prevent root diseases such as ginger stem rot, ginger blast and root rot. Four, timely control of pests The older the pest instar, the stronger the resistance and the more difficult it is to control. Therefore, we must adhere to the principle of "prevention and treatment of eggs and insects". The more serious pests on ginger include ginger borer (borinworm), beet armyworm, prodenia litura, thrips, whitefly, etc., 20% Kangkuan 10ml can be used, and 15 kg of water can be mixed and sprayed evenly. Spray once every 15 days and spray 3 times in a row. Disclaimer: Some articles on this website are transferred from the Internet.
