研究谷物在干筛子准备的苗床上的生长情况。 R. S. Edwards, Emp, J. expo Agrlc., 1957, 25, 167-84。通过筛分将土壤分成五种骨料尺寸；一半的地块通过用木板施加均匀的压力而被巩固。农作物为春大麦（3 年）和冬燕麦（2 年）。在所有情况下，土壤的细度都加速了发芽并略微提高了出苗率。由于机械阻力，最粗糙的苗床中的胚芽鞘常常以一定角度出现。合并加快了出苗日期，但降低了冬燕麦的出苗百分比；它对春大麦没有影响。温泉。
Studies of the growth of cereals on seedbeds prepared by dry-sIeving of the son. R. S. Edwards, Emp, J. expo Agrlc., 1957, 25, 167-84. Soil was separated into five aggregate sizes by sieving; half the plots were consolidated by applying an even pressure with a board. The crops were spring barley (3 years) and winter oats (2 years). Fineness of soil accelerated germination and slightly increased the percentage emergence in all cases. Coleoptiles in the coarsest seedbeds often emerged at an angle, owing to mechanical impedence. Consolidation accelerated the date of emergence but reduced the percentage emergence of winter oats; it had no effect on spring barley. S.P.A.
