花生为地上开花地下结果作物,具有较大的增产潜力,但由于受一些因素的制约,使其荚果多数不能完全发育和充实饱满。据试验,春花生一般单株开花100～150朵,而单株有效果只有10～13个,占8～10％。本试验采取标记果针入土时间和观察记载单株开花量的方法,以期达到探讨荚果发育的限制因素,为采取人为措施促进花生多结果和增加果重提供依据。
Peanuts flowering on the ground underground crops, with greater yield potential, but due to some constraints, most of its pods can not fully develop and full. According to the test, spring peanut generally 100 to 150 flowering plants per plant, while the single plant has only 10 to 13, accounting for 8 to 10%. In this experiment, we used the method of marking the time when the needle was inserted into the soil and observing and recording the flowering quantity of the individual plants in order to explore the limiting factors of the pod development and provide the basis for taking the artificial measures to promote the peanut multi-fruits and increase the fruit weight.
