Abstract

Biofertilizer can be used to replace chemical fertilizer so that soil quality is maintained and soil pollution can be avoided. The study aimed to determine the effect of biofertilizers with different compositions of microorganisms on the growth of maize plants. The research was carried out in a greenhouse. Maize plants were fertilized by two kinds of biofertilizers with different compositions of microorganisms. The first biofertilizer contained  Azotobacter sp,  Azospirillum sp,  Rhizobium sp,  Trichoderma sp,  and Lactobacillus sp, and the second biofertilizer contained Strenotrophomonas sp. and  Paenibacillus polymyxa. As controls, maize plants were fertilized by sterilized those biofertilizers. The results showed that the second biofertilizer increased the dry weight of the maize plant. Meanwhile, the first biofertilizer did not increase it. Several things must be considered in the application of biofertilizers, such as the composition of microorganisms, type of plant, level of fertilization, and the method of applying fertilizer to the plant.
具有不同微生物成分的生物肥料对植物生长的影响
生物肥料可以代替化肥,保持土壤质量,避免土壤污染。本研究旨在探讨不同微生物组成的生物肥料对玉米植株生长的影响。这项研究是在温室里进行的。用两种微生物组成不同的生物肥料对玉米植株进行施肥。第一种生物肥料含有固氮菌、固氮螺旋菌、根瘤菌、木霉和乳杆菌,第二种生物肥料含有养链单胞菌和多粘类芽孢杆菌。作为对照,玉米植株被无菌的生物肥料施肥。结果表明,施第二种生物肥料能提高玉米植株的干重。与此同时,第一种生物肥料并没有增加它。在施用生物肥料时必须考虑几件事,如微生物的组成、植物的类型、施肥水平以及对植物施用肥料的方法。
