众所周知,花生是一种开花多,结实少的作物,前人对造成开花多,结实少的原因作了不少的研究,这些研究着重于开花的先后,节位高低、气象条件等因素对有效花的效应。但是,对于在有效花期内受孕果针的成果机率,即在什么发育阶段决定其果/针比率及果/针比率的大小,受什么因素制约,还是很少见到报道。我们在多年的花生教学试验田的调查资料(见表1)中,可见到花生在有效花期内平均单株开花为38.4朵,受孕果针22条,针/花比率为0.59,如果这些受孕果针大部分能进一步发育成荚果,其产量是可观
As we all know, peanut is a flowering more, less robust crops, the predecessor of the reasons for causing more flowering, less sturdy made a lot of research, these studies focus on the flowering has first, the level of bits, meteorological conditions and other factors effective Flower effect. However, it is seldom reported about the outcome rate of conception fruit needles during the effective flowering period, that is, what stage of development determines the size of fruit / needle ratio and fruit / needle ratio, and what factors restrict it. We have many peanut teaching experimental field survey data (see Table 1), we can see the peanut flowering in the effective flowering period, the average flowering of 38.4 flowers, 22 needles, the needle / flower ratio of 0.59, if these conception needle Most can further develop into pods, the yield is considerable
