甘蓝叶球的形成受季节环境条件的影响,其中,温度影响作物中碳水化合物的生产和消耗,作用最大。我们以往的试验已经表明,甘蓝叶球的发育需要植株中氮的吸收同碳水化合物的生产保持平衡关系。因此,评价甘蓝植株的含氮状况,必须结合其它因素,要考虑到春、夏两季的高温对叶球发育可能产生的反作用。本试验是在受控的环境条件下进行的,目的是确定温度对甘蓝叶球发育的影响以及氮素供给与温度之间的相互作用关系。
The formation of cabbage leaf ball is affected by the seasonal environmental conditions, of which the temperature affects the production and consumption of carbohydrates in the crop and has the greatest effect. Our previous experiments have shown that the development of cabbage leaf need to balance the nitrogen uptake of plants with the production of carbohydrates. Therefore, to assess the nitrogen status of cabbage plants, we must combine other factors, taking into account the spring and summer high temperature on leaf development may have a reaction. This experiment was conducted under controlled environmental conditions in order to determine the effect of temperature on the development of cabbage leaf and the interaction between nitrogen supply and temperature.
