超高产花生开花与结果规律的研究

Sdudy on the Habit of Flowering and Fruiting of Super High-yielding Peanut

大田栽培条件下,研究了超高产花生(≥9.0 t/hm2)、高产花生(6.0 t/hm2)和一般产量花生(4.0 t/hm2)开花与结果规律。结果表明:超高产花生单株开花数、有效花数、果针数、有效果针数、荚果数和荚果体积均明显高于高产花生和一般产量花生;超高产花生单株日开花量高峰期比高产花生和一般产量花生提前7d左右,有利于提早结果和集中结果,为提高荚果数量和果重提供了保证,是超高产的重要基础。

Under conditions of field cultivation, the habit of flowering and fruiting of super high - yielding peanut （ ≥9.0t/hm2） , high - yielding peanut （ 6.0t/hm2 ） and common - yielding peanut （4.0t/hm2 ） were studied. The results show that, the number of flowers, valid flowers , gynophors, valid gynophores and pods of super high - yielding peanut were more than those of high - yielding peanut and common - yielding peanut significant ; the vol- ume of pod of super high - yielding peanut was much bigger obvious. The peak of per plant of super high - yielding peanut can flower earlier ahead of high - yielding peanut and common - yielding peanut about 7 days, it was benefi- cial to fruiting earlier and centralized, it provided a guarantee to increase the number and weight of pods, it was an important foundation for super high - yielding peanut.
