通过田间接种试验,研究了威廉腔环蚓(Metaphire guillelmi)活动对冬油菜(Brassicanapus)中双9号产量构成因素、籽粒产量和含油率的影响.结果表明:接种蚯蚓后,中双9号的一次有效分枝数、主花序角果数、每角粒数和千粒重均较未接种对照有增加趋势,但差异不显著;而单株角果数、单株产量和小区产量较对照显著提高,分别比对照增加了36.7%、46.5%和29.7%,这可能与蚯蚓促进油菜营养生长阶段植株生长及对氮素的吸收、累积有关.接种蚯蚓后,油菜籽粒含油率较对照有所降低,但由于蚯蚓活动显著提高了油菜籽粒产量,因此单株产油量和小区产油量仍比对照提高了37.4%和21.0%.
A field experiment was conducted to study the effects of the activities of Metaphire guillelmi on the yield components, grain yield and oil content of double 9 in Brassicanapus.The results showed that after earthworm inoculation, The number of effective branches, the number of inflorescences of main inflorescences, the number of grains per square and the weight of 1000-grain per plant increased more than those of unvaccinated control, but the difference was not significant. However, the number of per plant, the yield per plant and the yield of plot were significantly increased, Which were 36.7%, 46.5% and 29.7% higher than the control, respectively, which may be related to the growth of plant and the absorption and accumulation of nitrogen in the vegetative growth stage of earthworm.After earthworm inoculation, the oil content of rapeseed grains was lower than that of the control Due to the earthworm activity significantly increased the yield of rapeseed, oil yield per plant and plot oil production was still increased by 37.4% and 21.0% compared with the control.
