Free cutting: high temperature in summer causes less nutrient accumulation and consumption of leek, affecting plant growth, and increased leaf tissue fibers, rough texture and weak growth. At this time, it is generally not harvested, otherwise it will affect the growth and yield in autumn. At this time, plant cultivation should be strengthened to lay a solid foundation for autumn production.
Â
Weeding: In the hot and rainy summer, the extremely weeds breed and affect the growth of the leek, and it should be removed in time.
Â
Excerpt: Because the flowering knot of amaranth will consume a lot of nutrients in real time, affecting plant growth, tillering and accumulation of nutrients, thus affecting the annual output. Therefore, in addition to the cultivation of the field, it should be removed in time when the cockroach is young, in order to facilitate plant cultivation.
Â
Disease prevention: Amaranth is most prone to blight in the high temperature in summer, especially after heavy rain, and then exposed to hot sun, watery spots appear close to the ground, and the whole plant is dead in severe cases. Therefore, in the summer, it is necessary to pay attention to drainage and flood control. After heavy rain, the well water is shallowly poured, the ground temperature is lowered, and the yellow leaves are removed to make the ventilation between the rows good to reduce the harm. It can also be root-prevented with 50% carbendazim 500 times solution.
Â
Control of insects: The occurrence of cockroaches in summer is more serious. The prevention and treatment method is to use 50% phoxim 800 times solution combined with watering to slowly flow into the ditch. It is also possible to sprinkle phoxim granules when cutting the leek to fertilize the soil.
