How to manage leek in summer?

How to manage leek in summer? Please introduce the high temperature and rainy summer. In order to promote the healthy growth of Chinese chives, we should pay attention to the key points of management. First of all, there is no harvest in summer. The high temperature in summer leads to less nutrient accumulation and high consumption, which affects the plant growth, and the leaf tissue fiber increases, the texture is rough, and the commodity is poor, so the harvest should be stopped in summer in order to raise roots and promote trees. The second is fertilizer and water management. When the reporter interviewed Xianfengying Village, Wenjia Street, Shouguang City, Master Zhang, a vegetable farmer, told the reporter: "in summer, leek fertilizer and water management must be divided into varieties, such as' stupid 'leeks. Because green leeks are not easy to sell, generally sell leek bolts, watering and fertilizing should be early and sufficient. To provide good conditions for bolting. Such as Hanzhong, snow leek and other varieties bolting later, generally lower price, can properly control water, so that neither waste of fertilizer and water, nor affect nutrient accumulation, to lay a good foundation for selling green leek in winter. In order to prevent uneven fertilizer washing with water, fertilizer can be sprinkled. But be sure to spread it when there is no dew. You can use a broom several times to make the fertilizer on the leaves fall to the ground and then water it. " The third is to prevent lodging. Summer weather is hot and rainy, biennial leeks, if not cut in summer, tall leaves are easy to lodge, seriously affect ventilation and light transmission, easy to occur. In order to prevent leeks from lodging and reduce diseases, leek scaffolding should be set up, that is, a 30 cm-high wooden leek is fixed along a ridge at the east and west ends of the leek border, then a 2-meter-long bamboo pole is tied to the wooden leek, three thin steel wires are arranged on both sides and the middle of the border in the east-west direction, and then nylon ropes are set up in the middle of the wire according to the spacing of 25-33 cm to play a fixed role. Then between each ridge of leek, the thin bamboo pole is set on the nylon rope along the north-south direction, and the leaves can grow on the bamboo pole without lodging. The fourth is the timely harvest of leek bolts. After bolting, leek should be harvested in time in order to reduce the consumption of nutrients, fatten the rhizome and increase the yield of leek in winter. According to Master Zhang of Xianfengying Village, Wenjia Street, Shouguang City, the degree of fibrosis at the base of the leek should be paid attention to when harvesting, and it should be broken as a suitable harvest standard with a slight bend; if it is not crisp, it is more difficult to break, indicating that the leek stalk is older and has no commercial value. For the sale of leek bolts, stupid leeks should be harvested every three days, up to two months. When the price of leek bolts is low and no longer want to be sold, the young flower bolts should be cut off in time to facilitate root maintenance and cultivate healthy plants. Fifth, timely prevention and control of diseases and insect pests. In the case of high temperature in summer, leek is most prone to Fusarium wilt, especially when it is exposed to the hot sun after heavy rain. Therefore, in summer, under the premise of removing old and yellow leaves and keeping good ventilation between rows, 50% carbendazim and 500 times can be sprayed every 10-15 days to reduce the occurrence of diseases. In addition, it is necessary to control leek maggots in time, such as 48% maggot spirit, 48% Lesbon EC and so on.
