1.夏播糖甜菜种子的丰产因子有:选用良质的重大母根,通过移苗补栽保证全苗和选用肥沃士地。2.影响夏播糖甜菜种子更丰产的因子有:母根栽植的质量欠差和中耕不良,有碍种株的正常生长和造成了种株倒伏,从而降低了种子的产、质量,晚栽和拖延补栽母根,造成多数的无效植株。3.根据糖甜菜种株迅速生长情况,不必强调采种田三铲三蹚,为了兼顾种子的产、质量和田间管理方便,应考虑适当稀植,也应考虑带状栽植母根,以解决密植增产和田间理管技术之间的一些矛盾。
1. Summer sowing sugar beet seeds of the yield factors are: Selection of the quality of the major mothers, by planting seedlings to ensure that the whole seedlings and selection of fertile land. Affect summer sugar beet seeds more abundant factors are: poor quality of planting roots and poor cultivation, hinder the normal growth of plants and caused the lodging of plants, thereby reducing the seed yield and quality, late planting And delaying replanting of parent roots, resulting in most of the ineffective plants. 3. According to the rapid growth of sugar beet species, do not have to emphasize the mining three times three shovel farming, in order to take into account the seed production, quality and field management convenience should be considered appropriate sparse planting, should also consider the strip planting parent roots, to solve the close planting Some contradictions between increasing yield and field management techniques.
