Abstract:

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.

摘要：

为探究生物菌肥FBR1（枯草芽孢杆菌）不同施用方式对花生生长发育及产量的影响，以‘花育9113’为供试材料，以不拌种衣剂不施菌肥为对照1（CK1）、种衣剂1 250 mL·hm^-2拌种不施菌肥为对照2（CK2），设置地表撒施15 kg·hm^-2菌粉后起垄播种不拌种衣剂种子（T1）、不拌种衣剂种子播种后穴施菌粉15 kg·hm^-2（T2）、菌液7.5 L·hm^-2拌种（T3）和种衣剂1 250 mL·hm^-2拌种后用菌粉15 kg·hm^-2包衣（T4）4种不同处理，对各处理的花生植株发育、干物质分配及产量进行分析。结果表明，T1处理可促进花生生长，对单株荚果重和生物总干重有一定的增加作用；T3处理降低了出苗率，T4处理不仅降低了主茎高，而且降低了实收穴数；T1、T3处理的荚果和籽仁分别比CK1增产84.93、34.97和32.48、5.00 kg·hm^-2，T2处理的荚果和籽仁比CK1分别减产84.93和82.43 kg·hm^-2，T4处理的荚果和籽仁比CK2分别减产92.42 和32.47 kg·hm^-2，但增减幅度均不显著。综上，考虑威海土壤条件多样性，推荐地表撒施15 kg·hm^-2菌粉后起垄播种不拌种衣剂种子的施肥方式，并在做好示范试验的前提下，因地制宜施用FBR1生物菌肥。以上研究结果为生物菌肥在花生生产上的利用提供参考依据。
