玉米精密穴播技术是按农艺要求将单粒的种子播到土壤中特定穴坑中的一种播种技术。播种深度、播种粒数和株距都是预先设定的。在当前人力劳动成本高、良种价格高、良种出苗率高的情况下,精密穴播技术可以节约用种,节省用工,经济效益高。常规播种一般每穴2～3粒或者更多,或者半株距播种,用种量最少是精播 Corn Precision Bunching is a sowing technique that broadcasts a single grain of seed into a particular pit in the soil as required by agronomy. Sowing depth, sowing grain number and spacing are pre-set. In the current high labor costs, the high price of seeds, seed germination rate is high, the precision of planting technology can save seeds, save labor, high economic efficiency. Conventional sowing generally 2 to 3 per hole or more, or half a plant from the sowing, with the least amount of seed sowing
