不同甜菜种植区进行的研究说明,微量元素肥料对甜菜块根的产量和含糖量有良好的影响。为了研究含微量元素过磷酸钙对甜菜的作用,1967—1970年在可耕范围含腐植质2.58—3.08%的草原黑钙土地进行了试验。甜菜的前作物是多年生牧草后轮作的冬小麦。用 CKPH—12型播种机播种(雅尔图什科单粒种)甜菜,行距45cm。秋天把肥料(硝、钾盐、无微量元素的过磷酸钙)施入深翻地中。总共四小块地,每块地的面积是78.8—100米~2。依据每 The research on different beet planting areas shows that the trace element fertilizers have a good effect on the yield and sugar content of beet root tuber. In order to study the effect of trace element-containing superphosphate on beet, experiments were carried out on prairie black soil containing 2.58-3.08% humus in the arable land from 1967 to 1970. The beet’s former crop is winter wheat made from perennial grasses. Seeding (Yaltushchenko monocot) beet with CKPH-12 planter with 45cm spacing. In the fall fertilizer (nitrate, potassium, trace element-free superphosphate) into deep plowing. A total of four small pieces, each piece of land area is 78.8-100 meters ~ 2. Based on each
