High temperature and rain, the summer management of leeks must pay attention to weeds, drainage rake, strengthen fertilizer and water management and pest control, and reduce the number of harvest, and promote vigorous growth of leeks.
No cut. The high temperature in summer caused the amaranth to accumulate less nutrients and consume more, affecting the plant growth, and the increase of leaf tissue fibers, rough texture, and weakened growth. The harvest should be stopped from late June to early August to facilitate the cultivation of the roots. Harvesting can be carried out l~2 times from August to September, and harvesting will be stopped after late September. The last time you harvest, the cuts should be slightly higher. In particular, the leeks planted the year before last stopped harvesting during high temperatures during the summer. Each morning and evening, they sprayed water once with watering cans to keep the ground moist, but they could not be poured. Due to the favorable factors such as no cut, fertilizer and growth, etc., the Chinese leeks often fall down in summer. After lodging, it is perishable and induces disease and death. Measures to prevent lodging are: nitrogen fertilizer is not excessive; water should not be excessive; be diligent in flooding in case of heavy rain; the leek leaf should be cut short if lodging leaves are too long.
weeding. High temperatures in summer, rain in autumn, and breeding of weeds affect the growth of leeks and must be removed in time.
Picking up. As a result of flowering knots of leeks will consume large amounts of nutrients in real time, affect plant growth, childbirth, and accumulation of nutrients, thereby affecting the output in the coming year. Therefore, in addition to harvesting the fields, they should also be removed in time when young plants are tender and cultivate high-yielding plants.
Prevent blight. High temperature in summer and autumn, or sun exposure after the rain, is prone to blight. Symptoms are the appearance of water scalding near the ground. In severe cases, the whole plant will die. Management should pay attention to waterlogging prevention and removal of yellow leaves to maintain good ventilation between the lines, reduce the damage of diseases. Can also be used 50% carbendazim 500 times Irrigation root disease prevention.
Prevention and control. In summer, the occurrence of earthworms is more serious, and 50% phoxim 800 times solution can be used to slowly flow into the ditch. It is also possible to spray the phoxim granules during the cutting of the leeks and fertilize the soil, or to use the 20% of the “Cangjing†0.75 to 1 kg of water to the roots of the 1000 kg of water in the larval stage of the larvae.
