“…Oat is mostly grown in cool climate and sensitive to hot, dry weather from head emergence through to maturity, thus oat production is generally concentrated in latitudes from 35 to 65 o N (Suttie and Reynolds, 2004). Oat has been traditionally planted in cold regions of high latitudes and altitudes as grain for food and feed in China (Tian and Zhang, 2016), and as forage for livestock in recent years (Hou et al, 2021). However, the demand of animal husbandry for oat forage has been increased markedly (Fang et al, 2018;Kuang et al, 2018), as evidenced by rapidly increasing import of oat forage from 0.15×10 4 tons in 2008 to 30.81×10 4 tons in 2017 (Tao et al, 2018), and expanding growth area of oat forage from 5.5×10 4 ha in 2008 to 10.2×10 4 ha in 2015 in China (Hou et al, 2019).…”

Demand for high forage production and quality of oat (Avena sativa L., A nuda L.) by animal husbandry has increased in recent years, especially in the cold regions of northern China, because these regions are the traditional animal husbandry base. To maximize high quality of forage production, we developed a new model of two-sown regime for oat forage during a single growing season in an alpine region of Hulun Buir, Inner Mongolia Autonomous Region, China, using two early-matured oat species, Avena sativa (cv. Qinghai444, winner oat cultivar) and A. nuda (cv. Huazao2, spring oat cultivar). The key technologies and corresponding mechanisms in the first spring-sown and the second summer-sown were studied by measuring agronomic characteristics and forage quality and production. Furthermore, forage production and quality, resources use efficiency, and economic benefits were compared and quantified between two-sown regime and traditional one-sown regime across three consecutive years (2017–2019). We found that 1) the first sowing in spring was done when the thawing depth of soil at 10–13 cm occurred, and the forage yield was mainly achieved by an increase in plant height; 2) The second sowing after harvesting the first sowing oat forage was made in summer under no-tillage treatment, with the yield being mainly due to an increase in tiller density by increasing seeding rate; 3) Compared to traditional one-sown regime, dry weight yield, crude protein yield and relative feed value were significantly increased by 53.6%, 48.9% and 70.6% across three experimental years of 2017–2019, respectively. These results clearly demonstrate that the two-sown regime of oat is an effectively way in improving forage production and quality as well as increasing benefits in an alpine region of northern China.

“…In southern China, the scarcity of high-quality forage resources and the high costs of forage processing and transportation have posed significant challenges to the development of regional animal husbandry [1]. Therefore, the development of local coarse forage resources can greatly alleviate the shortage of forage resources in tropical animal husbandry [2].…”

In this study, the effects of mixed silage on the fermentation quality, chemical composition and bacterial communities of corn straw and soybean straw were assessed. Corn straws, soybean straws or a mixture of corn straws and soybean straws in a 1:1 mass ratio were uniformly mixed and processed using the same method to produce bagged silage weighing 50 kg per bag. At days 0, 14 and 60 of the fermentation process, the nutritional composition and fermentation quality indicators of each group were measured. A complete factorial design to assess the effect of the ensiling time, types of fermented straw (treatment group) and their interactions on the assessed parameters was performed. In addition, metabolomics sequencing and microbial community analysis were performed on the samples on the 60th day of fermentation. Compared with the corn straw group and the soybean straw group, the silage fermentation quality of the corn straw–soybean straw group is better, which is reflected in higher crude protein rate (p < 0.05), higher lactic acid content (p < 0.05) and lower ammonia nitrogen content (p < 0.05). The combined analysis of differential microbial taxa (species level) and differential metabolites revealed a positive correlation between certain bacterial species, such as manihotivorans, brevis and zeae, and significantly downregulated metabolites, such as pyrocatechol and N-benzoyltyramine. Similarly, positive correlations were observed between certain bacterial species, such as dublinensis, marcescens and agglomerans, and upregulated metabolites, such as D-xylonic acid and neochlorogenic acid. These findings suggest that the key microbial–metabolite pathways identified are responsible for the good fermentation quality observed during mixed fermentation of corn straw and soybean straw at a 1:1 mass ratio.

A novel application method of dung in restoring a degraded meadow steppe of Northern China

The rapid increase in amount of dung by intensive livestock feeding has caused serious environmental problems. Natural grasslands are limited by nutrients’ availability while the dung contains nutrients that cannot be directly used by plants. The lack of effective way to release the plant available nutrients from dung greatly limits the use of dung in an environmentally friendly way. We developed a novel methodology to effectively use dung in restoration of degraded grasslands by applying dung with urea and decomposition inducer in a field experiment. We further explored the mechanisms underlying the positive effect of the combined application of dung, urea and the inducer on a degraded grassland by monitoring changes in soil, plant and community characteristics for three consecutive years under combined application of urea and dung (UD), urea, dung and decomposition inducer (UDI), and no application as control (CK) in a degraded meadow steppe in Northern China. Application of UD and UDI significantly increased soil moisture, soil total nutrients, available macronutrients, and vegetation indexes. Soil nutrients and vegetation indexes were significantly higher by application of UDI than that of UD. Soil moisture was found to be a main driving factor in aboveground biomass for each treatment. In contrast, aboveground biomass was positively related to both soil moisture and soil nutrients in each experimental year, regardless of treatments. When all data were pooled as a whole, structural equation modeling analysis indicated that the UDI-induced increase in aboveground biomass was achieved by both increasing soil moisture, and soil total nutrients and available nutrients. The inducer can accelerate dung decomposition and enhance release of nutrients from dung to soil, thus contributing to restoration of degraded grasslands. Our results demonstrate a novel way to directly use dung by combining application of urea, dung and decomposition inducer in restoration of degraded meadow steppe.
