为研究水涝对不同基因型花生品种的影响,本实验以黑珍一号、新化小籽及其杂交01002-7-3组合为材料,在苗期进行正常灌溉(对照)、根部淹涝(含水量10%,40%,70%,100%;时间1 d,3 d,7 d)的处理,测定其主茎高、侧枝长、总分枝数、单株结果数、百果量、百仁量、产量。结果表明,黑珍一号、新化小籽、杂交组合的平均主茎高最高增幅分别为24.5%、33.2%、35.6%,侧枝长增幅分别为43.4%、27.8%、22.8%,总分枝数增幅分别为42.31%、28.8%、24.6%,单株结果数降幅分别为25.0%、5.7%、5.7%,其百果重最高降幅分别为11.6%、14.7%、3.2%,苗期根淹对黑珍一号、杂交组合的百仁重没有显著影响(p>0.05),根淹使得新化小籽的百仁重差异性显著(p<0.05),其最大增、降幅分别为16.9%、17.8%,根淹使得黑珍一号、新化小籽的产量最大降幅分别为32.8%、30.2%、8.68%。根淹40%1 d、10%3 d、40%3 d分别提高黑珍一号、新化小籽、杂交组合的产量16.9%、8.3%、13.6%。
In order to study the effect of waterlogging on peanut varieties with different genotypes, the experiment was conducted with the combination of black Zhen No.1, Xinhua Xiaozai and their hybrids 01002-7-3 as the materials, normal irrigation at the seedling stage (control) and root flooding (Including 10%, 40%, 70% and 100% water content for 1 d, 3 d and 7 d), and the main stem height, branch length, total number of branches, , A hundred of the amount of output. The results showed that the maximum increase of average height of main stem of Hezhen No.1 and Xinhua Xiaozao and hybrid combination was 24.5%, 33.2% and 35.6% respectively, and the increase of collateral length was 43.4%, 27.8% and 22.8% The increase rate of number per plant was 42.31%, 28.8% and 24.6% respectively. The decline of single fruit number was 25.0%, 5.7% and 5.7% respectively. The highest decline rate of fruit weight was 11.6%, 14.7% and 3.2% There was no significant difference (P> 0.05) between the seedling weight and the seedling weight per 100 kernel weight of hybrids (P <0.05) , 17.8% respectively. The maximum drop of Xinzhen small seeds was 32.8%, 30.2% and 8.68% respectively. Root flooded 40% 1 d, 10% 3 d, 40% 3 d increased the yield of Hezhen No.1 and Xinhua small seeds and hybrid combinations by 16.9%, 8.3% and 13.6% respectively.
