| 摘要: |
| 本试验由1984年9月至1986年5月底,在西北农业大学蔬菜试验站进行。通过定株观察、定期取祥、徒手切片追踪镜检观察及定期测定生长量,初步探明了草莓在关中地区自然温度下,花芽分化的时期、形态、每分化期所需旬均温、第1,2花序顶花分化所需的积温和天数;物候期与温度的关系;生育动态以及营养生长与生殖生长之间的关系。为正确制定草莓栽培技术提供了依据。 |

| Abstract: |
| The present paper preliminarily discussed the duration of and morphology of differentiation of flower buds and the mean temperature of one decade of the month for each differentiation of strawberry under the natural temperatures in Guanzhong area,and the accumulative temperatures and number of days required for the differentiation of acrogenous alabastrums of the first and second inflorescencer,the relation between phenological phase and temperature and among growth dynamics,vegetative growth and reproductive growth.Thus the bases are provided for working out the correct specification of cultivation techniques of strawberry. |
| Key words: strawberry,differentiation of flower bud,phenological phase=phenophase,growth dynamics |
