机械播种确有效率高、撤籽均、播量准确、节省籽种等优点。但许多谷物条播机,都属圆盘式开沟器,虽然大小不同、牌号各异,都源于苏联的24行小麦播种机,机械结构和性能基本相同。在小麦秋播中虽然大大显示其优越性;但在谷物春播作业中,有的问题值得研究和注意。从春播期间的气候环境和土壤条件看。春风较多,风速较大,春雨少,空气干燥,土壤水份散失较快,春季气温低,地温低,春播作物萌动,发芽, Mechanical sowing is indeed efficient, the withdrawal of seed are, sowing accuracy, save seed and so on. However, many grain planters are disk openers. Although they are of different sizes and grades, they all originate from the 24-line wheat planter in the Soviet Union with basically the same mechanical structure and performance. Although autumn wheat sowing has shown its superiority greatly, some problems in the spring sowing of cereals deserve study and attention. From the spring planting period climate and soil conditions. Spring breeze more wind speed, less spring, dry air, rapid loss of soil moisture, low temperature in spring, low ground temperature, spring planting germination, germination,
