“…Our results showed that mulching covers (especially the FM treatment) improved seed yield of V. unijuga in the subalpine region, which is consistent with results from studies of other crops, such as Setaria italica L. (Dong et al, 2014), Zea mays (Li et al, 2013), H. annuus (Zhao et al, 2014), and Brassica napus L. (Su et al, 2014) mulched with plastic film or straw. Pearson correlation indicated that seeds per pod was positively associated with seed yield, which agrees with the results of Bolaños‐Aguilar et al (2000) for M. sativa and those obtained by Vleugels et al (2016) for Trifolium pratense L. Therefore, we suggest that seeds per pod serve as an important indicator for improved V. unijuga seed yield.…”

Core Ideas Seed set of V. unijuga plants can be maximized by mulching in subalpine conditions. Plastic mulching increased seed provisioning, thus improving V. unijuga seed quality. Increased seed provisioning (mass) of V. unijuga improved germination success. Large seeds/seedlings have higher competitive ability relative to small seeds. ABSTRACT Our aim was to identify the soil and environmental modifications needed to improve seed set and seed quality of the perennial forage legume perennial vetch (Vicia unijuga A. Br.) in harsh subalpine conditions. A 3‐yr field experiment was conducted in a subalpine zone of China to evaluate the effects of modified soil temperature and moisture conditions generated by no mulching (control), plastic film mulching (FM), removal of plastic film mulching at the 30% flowering stage (RM), and threshed barley straw mulching (SM) on seed set, mass, reserves, germination, and seedling growth. The FM and SM treatments were efficient in increasing seed maturation and decreasing ovule abortion at the base of the pods. There were higher 100‐seed weight (HSW) and seed nutrient reserves in the FM and RM treatments, accompanied by higher final germination percentage (FGP) and lower time to 50% germination (T50) and greater initial seedling growth than in the control, whereas the reverse was true for the SM treatment. Modified soil temperature and moisture generated by mulching improved offspring performance traits of V. unijuga through an increase in HSW. The HSW was positively correlated with FGP and seedling growth traits and was negatively associated with T50. In conclusion, the FM treatment provided adequate soil temperature and water resources to maximize seed set by V. unijuga plants. The well‐provisioned seeds from this treatment conferred the advantages of good offspring performance on high germination and seedling growth traits.

“…Even when perennial vetch was subjected to drought stress at the reproductive stage in 2015, the FM treatment increased soil temperature and moisture conditions for increasing seed yield compared to the other mulching treatments and the control. These results were consistent with those for M. sativa (Jia et al, 2006), Z. mays (Zhang et al, 2011) and S. italica (Dong et al, 2014), suggesting that plants under the FM treatment maintained high transpiration rates through acquisition of soil water and nutrients, required for photosynthesis to increase seed yield.…”

Contributions of soil temperature and moisture drivers to variations in perennial vetch (Vicia unijuga) productivity potential in the Qinghai-Tibetan Plateau region of China

In alpine regions of the Qinghai-Tibetan Plateau of China, perennial vetch (Vicia unijuga A. Br.) productivity is often low and variable, constrained by the cold and erratic precipitation environment. The aim of the current study was to identify the soil-environmental modifications needed in harsh alpine environmental conditions for improvement of perennial vetch growth, forage biomass production and seed yield. A 3-year field experiment was conducted in an alpine region of China to evaluate the effects of modified soil temperature and moisture conditions generated by three mulching treatments – plastic film mulching (FM), removal of plastic film mulching at the 30% flowering stage and barley straw mulching – on perennial vetch productivity. Higher mean soil temperature and soil water content were recorded in the FM treatment than in the control and other treatments. This enhanced perennial vetch growth, as indicated by higher photosynthetic rate, higher leaf area index and greater above-ground dry matter, and thus higher seed yield and water productivity. Examination by multiple linear regression showed the relative contribution of mean soil temperature to the variations in photosynthetic rate, above-ground dry matter and seed yield were greater than soil water content, whereas the reverse occurred in seeds/pod. In conclusion, the FM treatment provided adequate soil temperature and water resources to improve photosynthetic rate, above-ground dry matter, seed yield and water productivity, and thus increased the productivity potential for perennial vetch in the alpine region. The current research provides scientific support for large-scale perennial vetch cultivation and management in alpine regions.

“…Plastic film mulch has been widely used in agriculture, especially in arid and semiarid regions, since it can save soil water by reducing evaporation [1] and optimize the light and thermal environments for crops [2][3][4][5][6][7][8][9][10][11]. Accordingly, plastic film mulching can improve seed emergence [12,13], root growth [14,15], nutrient uptake [16], stem elongation [5,11], final yield and water use efficiency [17][18][19][20][21].…”

Plastic film mulch is an important agricultural technology to reduce water evaporation and modify the soil thermal conditions for crop production. The optical properties of plastic film mulch and the crop canopy growth are both key factors impacting soil heat transport in the soil-film-canopy-atmosphere ecosystem. In this study, a process-oriented model was developed to better understand the interaction among the plastic film mulch, potato (Solanum tuberosum L.) canopy growth, and soil thermal conditions. Canopy growth, photosynthetically active radiation transmittance, net radiation, soil heat flux, and temperature were monitored in a two-year plastic mulch field experiment in Wuwei (Gansu Province, China). Results showed that the simulation of daily soil surface temperature had a good performance with 2.8 and 1.5 °C of root mean square error (RMSE) for the transparent film mulch (TM) and black film mulch (BM), respectively. Moreover, the simulation of the daily net radiation and soil heat flux model indicated reasonable fluctuations with potato phenological development with the daily R2 ranging from 0.89 to 0.98 in 2014 and 2015 for the TM and BM treatments. It was shown that the canopy temperature under BM was greater than that in TM treatment, and the maximum value difference could be up to 7 °C during the early potato growing period, which implied that the BM may perform better in modifying the canopy thermal condition. The model could provide heat distribution information for plastic film choosing in potato field to avoid heat stress.
