Sweet corn cultivation techniques
1. Selection of land: Choose a land with good water conservancy conditions and good soil texture. 2, transplanting seedlings: nutrition seedlings nursery or nutrition plate seedlings 3. Seedling management: Single seeding, timely watering, weak seedlings can be suitable for pouring water or spraying a small amount of urea. 4, standard opening: According to 1.1 meters open, ditch 20cm, the central shallow open fertilization ditch, Mushi decomposed farmyard fertilizer 1000 ~ 2000kg, farmhouse No. 1 (corn) 60kg, fully mixed and smooth. 5. Covering of mulching film: Before cover film, use 41% of Yu Nongsi's EC to spray 100 g to kill grass on the surface of mu. Implement the method of membrane-breaking and colonization after covering the membrane. 6, wide and narrow row oriented transplanting. Specifications (90 + 40) / 222cm, 4300 acres planted, after planting pouring root water. 7, fertilizer and water management: 10 days after planting can be applied top, Mushi 5kg urea to raise the seedlings, large bell-mouth urea 15-20 kg, foliar spray Prodan (high potassium) 600 times liquid 3 to 4 Times. 8, in addition to 蘖 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞 苞. 9. Pest control: Corn borer: Use 5% Sodium Tetrachloride 70-90ml/mu or 48% Le Siben EC 50-80ml/mu watered field spray, and spray in the morning is appropriate. Aphids and Pieris: 50% of smallpox is sprayed with green waves (bio-pesticides) 800-1000 times of total field spray and sprayed once every 10 days. 10, timely harvest: 18-22 days after the general pollination can be harvested, at night or early morning when the cold is better. 11, fresh ear classification listed. High Precision Distance Sensor Laser range sensors combine the advantages of a visible red sensing beam with the increased range of a laser. The optical distance sensor devices are Class 2 lasers, support Class 1 customized. The high precision autonics distance sensor is successfully be used to connect to Arduino, Raspberry Pi, with +-1mm to 3mm high accuray, and long-range solutions (max up to 150m) for your application.
