一、扁平果 果实横径明显大于纵径的果实,在圆球形或近球形品种中表现突出。 原因:(1)幼果生长前期纵向未能充分发育。(2)植株营养生长弱,叶形小,叶片面积不足,果实生长得不到充足的同化养分,果实生长受阻。(3)低节位所结果实,结果发育处于较低温度。夏季栽培高温下也易形成扁平果。 调节措施:(1)调节栽培季节和改善设施栽培的光温条件,使果实发育处于正常温度(前期适宜日均温度23℃～24℃,果实膨大期理想日温27℃～30℃)条件下。(2)控制
First, the flat fruit is significantly larger than the diameter of the longitudinal diameter of the fruit, spherical or nearly spherical varieties outstanding. Reasons: (1) young fruit growth in the longitudinal failure to fully develop. (2) vegetative growth of plants is weak, leaves small, lack of leaf area, fruit growth can not get enough assimilation nutrients, fruit growth retardation. (3) low node results, the results at a lower temperature. Summer cultivation is also easy to form a flat fruit under high temperature. Adjustment measures: (1) Adjust the cultivation season and improve the light and temperature conditions of the cultivation so that the fruit development will be under the normal temperature (the average daily temperature of 23 ℃ ~ 24 ℃ in the early stage and the ideal daily temperature of 27 ~ 30 ℃ in the period of fruit enlargement) . (2) control
