Xia Wei Caiqiao Management

Free cutting: high temperature and rain in summer, resulting in less nutrient accumulation of amaranth, high consumption, and increased leaf tissue fibers. At this time, it is generally no longer harvested, and plant cultivation should be strengthened to lay a good foundation for the high yield of autumn leek.

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.

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.

Disease prevention: Amaranth is most prone to blight at high temperatures, especially after heavy rain, and it is exposed to hot sun. In the vicinity of the ground, hot spots are formed. In severe cases, the whole plant is dead. Therefore, in the summer, it is necessary to pay attention to drainage and flood control. After heavy rain, water is poured with well water to reduce the ground temperature, and 50% carbendazim 500 times solution is used to prevent disease.

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, or to sprinkle phoxim granules when cutting the leeks and fertilizing the soil.
