“…The formation of generative parts might have reduced the energy content in leaves and stalks at this stage. These changes directly depend on changes in the chemical composition of plants, which is related to energy content in plants (Yajing et al, 2007) or leaf/stem ratio and energy content in these different plant parts (Hakl et al, 2010).…”

The aim of this paper was to evaluate catch crops for energy production and effectiveness in the areas with limited precipitation. ) was significantly (P < 0.05) influenced by species and year. In average of 2005-2007, the total energy production was 18.19 GJ ha -1 in un-seeded control (production of weeds and volunteers) and ranged from 24.74 to 57.02 GJ ha -1 in the stands with evaluated catch crops. Catch crops represented 43-94% of the total energy production depending on plant species. Gain of positive energy balance of evaluated catch crops was influenced particularly by the year in relation to soil moisture by contrast to the un-seeded control. In all three years, positive energy balance was reached only by the stand with S. alba. P. tanacetifolia performed at the lowest value of additional energy and R. sativus performed at the highest energy accumulation in underground biomass.

“…The content of energy in plant material is given by the chemical composition in the plants and it can differ for individual plant species (Yajing et al, 2007). In mixed association, such as permanent grasslands, the content of energy is dependent on composition of species, but it can be changed during the vegetation (Neitzke, 2002).…”

“…Leymus chinensis (Trin.) Tzvel., a eurytopic xerophytic grass, accounts for approximately half of the biomass of the steppe [29]. This grass produces a high yield, has a strong tolerance to drought, high pH and low fertility [30], and is usually used as hay to feed livestock.…”

The Effect of Fertilizers on Biomass and Biodiversity on a Semi-Arid Grassland of Northern China

et al. 2019

Semi-arid grassland in northern China faces degradation and desertification problems, with fertilizer application appearing to be a potential solution by improving soil fertility and plant fields or biodiversity. In this study, mineral and organic fertilizers were used in a semi-arid natural grassland in Hebei Province for three years. The plant characteristics, biomass and species diversity index were assessed and analyzed. In the years 2016 and 2017, mineral fertilizers (RC) significantly increased the total aboveground biomass and the aboveground biomass, natural height, density and coverage of Leymus chinensis compared with organic fertilizers (RO), especially at a moderate application rate (RC2). Leymus chinensis was first divided into its own group and then separated into four groups via cluster tree analysis. The importance values of Leymus chinensis showed continuous increases in mineral fertilizer treatments, but not for organic fertilizers. Margalef’s species richness indexes increased significantly (to 2.09) in the organic treatment (RO1) when compared with RC2. Thus, it was concluded that mineral fertilizers could enhance the position of Leymus chinensis in the natural grassland, while organic fertilizers could promote species biodiversity. This study also provides recommendations regarding the use of fertilizers for the purposes of increasing plant biomass and biodiversity in semi-arid grasslands of northern China.
