March and April vegetable farming

In April, the temperature has risen remarkably. It is necessary to do a good job in the cultivation of oleracea or open-planted eggplant melon beans, leafy vegetables and aquatic vegetables, and pay close attention to weather forecasting to prevent cold weather. The winter vegetables in the open field should be done in the process of returning to the topdressing and cultivating soil and weeding.

1. Sowing and transplanting mulch, lentils, green peas, peas, cucumbers, melons, melons, melons, leeks, peppers, small greens, leeks, auricula, sage, leeks, ginger , cauliflower, etc.

2, strengthen vegetable field management, check seedlings to fill the gap, loose soil and grass, watering and fertilizing, early scaffolding tied vines, point flowers red, artificial pollination, solanaceous fruit pay attention to pruning, watering and fertilizing; melon pruning, topping , preserved flowers and preserved fruit, root melon in time for early harvest; beans, kidney beans, peas, roots, pruning, picking, fertilization, cultivating loose soil, lentils, cultivating and weeding, potato topdressing, spraying paclobutrazol, phosphoric acid Dihydrogen potassium, etc.; onion and garlic topdressing, drainage and stain removal and picking in time; radish, carrot seedlings, watering and topdressing; spring cabbage, spring lettuce, clear ditch drainage, topdressing; leafy vegetables, thin application, farmer's fertilizer.

3, pay attention to the prevention and treatment of solanaceous diseases, blight, gray mold, leaf mold, virus disease; melon wilt, downy mildew, anthracnose, powdery mildew and yellow squash, melon, melon; beans Rust and Liriomyza sativae, pea pods; potato late blight; leafy aphids, diamondback moth, cabbage caterpillar, yellow stripe armor; lettuce, onion, leeks and retained strains against sclerotinia, gray mold, downy mildew Diseases, diseases and convulsions.

Industrial Laser Distance Sensor

Industrial Laser Distance Sensor, we also call it secondary development laser distance module, which support TTL level and CMOS. The laser range sensor can be widely used in professional surveying, mapping, construction, robots, hunting arrows, industrial monitoring and automated measurement applications in electricity, transportation, etc. Our laser distance module supports data communication with RS232, USB with a simple adapter. The results of laser distance sensor can be evaluated with Arduino. We are always looking ahead, hoping we can make every measurement simple in life!
