Effects of Increase Applying of Biofertilizer Strain FBR1 on Growth Development and Yield of Peanut
In order to explore the effects of different application methods of biofertilizer FBR1(Bacillus subtilis)on the growth and yield of peanut,'Huayu 9113'was used as the test material.Taking without seed coating agent without bacterial fertilizer was used as control 1(CK1),with seed coating agent 1 250 mL·hm-2 without bacterial fertilizer as control 2(CK2),4 treatments were set up,including spread 15 kg·hm-2 bacterial powder on the surface and sow seeds without seed coating agent after ridging(T1),without seed coating agent after sowing applied with 15 kg·hm-2 bacterial powder in the hole(T2),with 7.5 L·hm-2 bacterial liquid for seed dressing(T3)and with 1 250 mL·hm-2 seed coating agent after coating with 15 kg·hm-2 fungus powder(T4),and peanut plant development,dry matter distribution and yield of each treatment were analyzed.The results showed that T1 treatment could promote the growth of peanut,and increase the pod weight per plant and total biological dry weight.T3 treatment reduced the seedling rate.T4 treatment not only reduced the main stem height,but also reduced the number of harvested holes.The pods and kernels of T1 and T3 treatments were higher than those of CK1,which increased by 84.93,34.97 and 32.48,5.00 kg·hm-2,respectively.The pods and kernels of T2 treatment decreased by 84.93 and 82.43 kg·hm-2 compared with CK1.The pod and seed yield of T4 treatment decreased by 92.42 and 32.47 kg·hm-2 compared with CK2,but the increase and decrease were not significant.In summary,considering the diversity of soil conditions in Weihai,we recommended the method of sowing seeds without seed coating agent after surface spreading 15 kg·hm-2 of fungal powder and applying FBR1 biofertilizer according to local conditions on the premise of a good demonstration trial.Above results provided a reference basis for its application in peanut production.
