作者用甘兰型油菜农林16进行了两个试验:试验Ⅰ:自始花至临近成熟期分五期剪去全部叶片和遮光处理(自然光照的80％);试验Ⅱ:开花末期疏荚(25％和50％)。剪去全部叶片、遮光(50％自然光照)。其所得资料分析了不同时期和处理对产量构成的影响,结果摘要如下: 一:每株荚数自始花至开花末期持续增加,而后位于花序上部的幼荚变成荫荚,全株荚 The authors conducted two experiments with Brassica napus Agro-forestry 16: Experiment 1: All leaves and shading treatments (80% of natural light) were cut from five stages of flowering to near maturity; Experiment II: 25% and 50%). Cut off all leaves, shading (50% natural light). The obtained data analysis of the different periods and the impact of processing on the yield structure, the results are summarized as follows: First, the number of pods per plant from the beginning to the end of the flowering continued to increase, and then located in the upper part of the inflorescence into a new pod,
