Winter ploughing, fine hoeing, and irrigation are both important measures to ensure the increase of cotton production in the coming year, and are also effective ways to eliminate overwintering bollworms.
Winter ploughing. Cotton bollworms generally spend more than two and a half centimeters from the ground to pupate overwintering. Winter plowing can destroy the diverticula and reduce the emergence rate in late spring. Some insect galls are turned to the surface to make them dead, frozen or eaten by natural enemies; or Some insects were plunged into the deep soil, so that they couldn't be normally feathered and soiled. The sooner the winter plowing time is, the better the plowing will be before the land is frozen to prolong the weathering time, improve the pest control effect, and help to accept more rain and snow. Plowing depth should be more than 15 cm. The deeper the winter plowing, the better pest control effect. Due to the strong fly ability of adult Helicoverpa armigera, winter plowing and disinfestation must be conducted in large areas to be effective.
Cultivate and combine. Before the winter ploughing, the hoe should be smashed again. After the ploughing, the smashing and smashing can be performed. The water can be stored and the squat can be killed.
Water after cultivation. After winter ploughing followed by winter irrigation or spring irrigation, not only can the soil be settled and weathered, but also the mortality rate of overwintering lice can be increased.
1000Hz High Frequency LiDAR System
JRT High Frequency Range LiDAR Sensor is 2021 new product, that's a low-cost tof sensor but High frequency (up to 1000Hz). With 5cm high accuracy, the LiDAR Module can measure 80m.
