Without cutting
The high temperature and rain in summer resulted in less accumulation of nutrients and consumption of leek, and increased tissue fiber in the leaves. At this point, it is generally no longer harvesting, plant culture should be strengthened to lay a good foundation for the autumn amaranth yield.
Abstract
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 for the plant to grow.
Weeding high temperature and rainy summer, the breeding of weeds, affect the growth of leeks, it should be removed in a timely manner.
Disease prevention
The leeks are most likely to cause blight at high temperatures, especially after heavy rains encounter sun exposure, and hot scalding spots occur near the ground. In severe cases, the whole plant dies. Therefore, it is necessary to pay attention to drainage and flood prevention in the summer, use well water after heavy rain to reduce the temperature, and use 50% carbendazim 500 times to root and prevent disease.
Pest control
In summer, the occurrence of cockroaches is more serious. The prevention and control method is to use a 50% phoxim 800 times solution with water to slowly flow into the ditch. It is also possible to sprinkle phoxim granules when cutting and cropping the leek.
