    摘要:

    为了探究在辽宁省花生过早剥壳是否会影响种子发芽率、出苗率及产量,本研究于2017年、2018年以农花5号、农花13和花育22为试材,研究了不同剥壳时间对花生发芽率、出苗率及产量的影响。结果表明,不同处理间种子含水量均较低,2017年T1处理种子含水量变幅为4.25%~4.29%,T3处理变幅为3.52%~3.59%,同一年份同一品种不同处理的种子含水量差异均未达到显著水平;不同剥壳时间对花生发芽势、发芽率、发芽指数和活力指数均无显著影响,对出苗率、产量构成因素及产量的影响差异均未达到显著水平。因此,在辽宁省无论是几月份剥壳,均不影响花生的发芽率、出苗率及产量,证明辽宁省花生在春节过后即可剥壳,可避免花生播种前集中剥壳而造成人力、机械紧张的问题。

    Abstract:

    In order to investigate the effects of early shelling peanut on seed germination rate, emergence rate and yield, NH5, NH13 and HY22 were used as experimental materials to perform the effects on seed germination rate,emergence rate and yield on different shelling time in Shenyang Agricultural University(2017~2018). The results showed that the water content of seeds in different treatments was low. For example, in 2017, the water content of seeds in T1 treatment varied from 4.25% to 4.29%, and that in T3 treatment varied from 3.52% to 3.59%. However,the water content of seeds in different treatments of the same variety in the same year did not reach a significant level. Shelling at different time had no significant effect on germination potential, germination rate, germination index and vigor index of peanut, and had no significant effect on emergence rate, yield components and yield.Therefore, in Liaoning Province, no matter how many months of shelling, it does not affect the germination rate, emergence rate and yield of peanut, which proves that peanut can be shelled after the Spring Festival in Liaoning Province, which can avoid the problem of manpower and machinery shortage caused by centralized shelling before sowing.
