“…Potato growth is optimum when mean air temperature is around 15–18°C during the cropping cycle (Singh, Singh, Arora, & Sekhon, 2015). Appropriate temperature is crucial to increasing potato yield and RBT (Li et al., 2018; WoLi et al., 2018). Our results showed that the SM treatment significantly reduced soil temperature at 0–25‐cm layer by 0.8–1.4°C during the growing season (Figure 4), which was consistent with the findings by Kar and kumar (2007) and Lu et al.…”

“…With the annual precipitation within the range of 250–550 mm, the region is characterized by a droughty climate with unevenly distributed rainfall, high evaporation, and low and unstable farmland productivity (Wu et al., 2017; Xiao, Xiao, Long, Yong, & Feng, 2014). Potato ( Solanum tuberosum L.) is one of the main economic and staple food crops traditionally planted in the semiarid Northwest China, accounting for 36% of China's total potato land area, which plays a critical role in ensuring food security (Li, Li, Zhang, Zhang, & Chen, 2018). However, the potato productivity and yield are lower in these areas due to the limitation of the soil water availability (Gan et al., 2013).…”

“…For film mulching, several techniques have been developed which include: alternating narrows and wide ridges both mulched by polyethylene film (PMF) (Gan et al., 2013; Mo et al., 2017); alternating large ridges and small furrows with only the ridges mulched with polyethylene film (PMP) (Li, Hou, Wang, Jia, & Han, 2016) and flat plots mulched with plastic film (Li et al., 2010). Many studies have found that film mulching can reduce soil water evaporation (Gu, Li, & Du, 2017; Zhao et al., 2014), increase topsoil temperature (Zhao et al., 2014), improve crop emergence (Feng et al., 2019), and increase soil water storage (Mo et al., 2017), suggestive of improving WUE as well as crop yield (Li et al., 2018; Qin, Zhang, Dai, Wang, & Deming, 2014). Accompanying the benefits, however, are some problems caused by the plastic film mulching.…”

“…Some studies have found that both positive and negative effects existed with the practice. One the one hand, with the increase in mulching amount, the crop yield and WUE also increased; on the other hand, it remarkably reduced temperature (Li et al., 2018), making it difficult for mechanized farming. Therefore, to address the conflict between soil water conservation and the remarkable decrease in soil temperature with full straw mulching, we have developed a new straw mulching technique called “straw strip mulching system (SM)”.…”

Straw mulching is widely used in agriculture to conserve soil water and improve crop productivity. The effects of straw strip mulching and film mulching on dryland soil water storage and temperature, potato (Solanum tuberosum L.) growth and yield, and water use efficiency (WUE) were examined from 2014 to 2015 in the rainfed semi-arid regions of China. Field experiments were conducted with four treatments: (a) alternating strips mulched with maize (Zea mays L.) straw and bare plots with no ridges (SM); (b) alternating large ridges and small furrows with only the ridges mulched with black polyethylene film (PMP); (c) alternating narrows and wide ridges both mulched by black polyethylene film (PMF), and (d) traditional bare land planting without mulching (CK). The results indicated that film mulching had positive effects on soil water storage at the early stage of potato growth, while the SM significantly improved soil water storage at the late growth stage. Soil water storage (0-2-m depth) was 11.3-35.4 mm greater with the SM than that with the other treatments, especially during the tuber bulking in summer drought period. Compared with the CK, the SM significantly decreased soil temperature by 0.8-1.4 • C, and increased potato yield by 10.5-34.2%, WUE by 8.9-29.8%, and commodity rate by 14.7-38.8%. Compared with the PMP and PMF, the SM increased potato yield by 4.6-12.9 and 3.4-9.3%, respectively. This might be contributed to increased soil moisture and lower soil temperature, which promoted potato growth, yield, and commodity rates.Abbreviations: CK, traditional bare land planting without mulching; ET, evapotranspiration; PMF, narrow and wide ridges mulched by black polyethylene film; PMP, large ridges and small furrows only ridges mulched with black polyethylene film; SM, straw strip mulching; SWS, soil water storage; WUE, water use efficiency.

“…Potato (Solanum tuberosum L.) is a highly adaptable crop. The potato planting area in the loess plateau region accounts for 36% of the total potato planting area in China [1]. On one hand, the potato is rich in starch, protein, vitamin C, sugar, and various mineral salts, which have high nutritional value in food [2].…”

The Correlation between Soil Nutrient and Potato Quality in Loess Plateau of China Based on PLSR

et al. 2020

Potato tuber quality is influenced by the interaction of soil nutrients. Hence, simple correlation analysis cannot accurately reflect the true relationship between soil nutrients and potato tuber quality. In this study, potato tuber quality and soil nutrient content were used as research materials in the Loess Plateau of China. The partial least square regression (PLSR) method was used to establish the regression equation between potato quality and soil nutrient. The major soil nutrient indexes influencing potato quality were screened out to provide theoretical basis for potato field management. The results showed that the major soil nutrient factors influencing the potato tuber quality in Loess Plateau were soil ammonium nitrogen, soil nitrate nitrogen, soil available phosphorus, pH, and soil available potassium. Soil pH value is the most important factor affecting potato starch, reducing sugar content, and soluble protein content. Soil nitrate nitrogen is one of the important factors affecting potato tuber soluble total sugar content, vitamin C, browning intensity, and polyphenol oxidase activity. Soil ammonium nitrogen was positively correlated with the total soluble sugar content of potato tubers, and negatively correlated with reducing sugar content, browning intensity, and polyphenol oxidase activity. However, soil available potassium has positive effects on potato starch and reducing sugar content, and negative effects on soluble protein and browning strength. Results of this study indicates that the major soil nutrient factors influencing potato tuber quality were soil nitrate nitrogen and soil pH value.

The activities of soil resident enzymes and fungal communities are critical for soil health and ecosystem functionality. However, their dynamics in response to variations in sowing techniques are poorly understood. This study aimed to investigate the effects of wide-ridge and narrow-furrow (WR&NF), film-mulching ridge (FMR), and conventional drilling (CD) practices on the activities of soil-residing enzymes and fungal communities in a dryland wheat field on the Loess Plateau. Photometrically, unbuffered, and colorimetric methods were employed to determine the activities of alkaline phosphatases, urease, and sucrase enzymes, respectively. Soil fungal diversity and community composition was measured via the Illumina Miseq 2500 sequencing method. The results revealed that WR&NF and FMR practices significantly enhanced the soil activities of alkaline phosphatases, urease, and sucrase, while improving soil fungal communities including Chytridiomycota phylum and Phoma (Ascomycota), Olpidium (Chytridiomycota), and Trichosporon (Basidiomycota) genera. Both the enzymatic activities and fungal community compositions of the soils under study varied from rhizosphere to non-rhizosphere, as well as at different soil depths. Remarkably, several soil fungal genera, including Cystofilobasidium (Basidiomycota), Triparticalcar (Chytridiomycota), and Guehomyces (Basidiomycota) were more abundant in the subsoil than topsoil. In general, we observed that ridge-furrow and film-mulching practices enhanced the enzyme activities and improved fungal communities of soils. Therefore, the wide-ridge and narrow-furrow sowing technique is recommended as an environmentally compatible practice to benefit the arid wheat (Triticum aestivum L.
