“…The RFPFM is increasingly used by wheat producers to improve crop yield and water use efficiency in arid, semi‐arid, and semi‐humid regions (Gan et al., ; Li et al., , , ; Zhou et al., ). However, to the best of our knowledge, the lodging susceptibility of wheat crop under RFPFM has not been evaluated in any study.…”

“…The reason could be that the increase in breaking resistance was not greater than the increase in BM under RFPFM, compared with FP. The favorable hydrothermal conditions under RFPFM, could lead to an increased plant height, aboveground dry weight, the length of the basal internode, LAI, and plant dry weight (Li et al., , ), resulting in higher BM, which made plants prone to lodging. Such findings are further supported by strong relationships of lodging index with the parameters described above (Supplemental Fig.…”

“…This shift would play a critical role in guaranteeing water sustainability and food security in the irrigated regions of dry semi‐humid regions. Another important concern that should be emphasized is that RFPFM planting requires more labor and additional costs for plastic films, which could decrease the net economic benefits and increase the potential of so‐called “white pollution” to our environment (Li et al., , ). Therefore, it calls for technological advancements, such as innovative mechanization, and some alternatives (biodegradable and photodegradable plastic mulch films, etc.)…”

“…The RFPFM system, as one of the water‐saving practices, is currently popular in arid and semi‐arid areas of northwestern China (Li et al., , , ; Zhang et al., ; Zhou, Li, Jin, & Song, ). The RFPFM system is comprised of alternate flat furrows and mulched hemispherical ridges, which has a greater potential for rainwater collection and therefore leads to deeper water penetration in furrow by preventing evaporation from the soil (Li et al., ; Zhang et al., ; Zhou et al., ).…”

Ridge-furrow with plastic film mulching (RFPFM) is widely used as a water-saving strategy for the improvement of crop yield. However, lodging susceptibility under RFPFM practices has not yet been determined. A 2-yr field study comprising of three cultivation strategies (rain-fed flat planting [FP], RFPFM, and well-water planting [WW]) and two N application rates (75 and 225 kg N ha -1 ) was conducted to assess the risk of lodging and the relationship between lodging resistance and grain yields of two wheat (Triticum aestivum L.) varieties (Xinong979 as lodging resistant and Xiaoyan22 as lodging susceptible). The results showed that higher N application increased lodging index under FP and RFPFM, and the lodging index was 33% lower under RFPFM than under WW. In both years, there was a positive relationship between grain yield and lodging susceptibility (R 2 = 0.62** and 0.57**) implying that promoting crop yield by using RFPFM strategy accelerates the risk of lodging. When compared with WW, RFPFM significantly reduced the lodging index, while sustaining a comparable grain yield. Overall, RFPFM could be highly recommended as a promising strategy for winter wheat producers in dry, semi-humid regions. The close relationships of breaking resistance and lodging index with both mass density and stem wall thickness of basal internode suggest that selection for increased stem strength trait could lead to improved lodging resistance and higher yields in future programs for winter wheat cultivar improvement.Abbreviations: BM, bending moment; DAS, days after sowing; FP, rain-fed flat planting; LAI, leaf area index RFPFM, ridge-furrow with plastic film mulching; WW, well-water planting.

“…The main reason for farmers to adopt this method is that shallow‐buried drip irrigation can still achieve high yields and can also reduce the use of mulch, thus reducing planting costs and pollution from mulch residue. Although there have been many studies on different cultivation patterns for plastic film mulching, 12–14 there has been little research comparing the two kinds of drip irrigation. We assumed that the water and fertilizer utilization efficiency of the two drip irrigation methods must be different.…”

Can drip irrigation under mulch be replaced with shallow‐buried drip irrigation in spring maize production systems in semiarid areas of northern China?

BACKGROUND In recent years, shallow‐buried drip irrigation in spring maize production has gradually replaced drip irrigation under plastic films and has become a common irrigation method in semiarid areas of northern China. RESULT Two years of field experiments were carried out in the semiarid area of western Jilin province to compare the two drip irrigation methods in the spring maize production system. The treatments included MW1 (drip irrigation under mulch + moderate irrigation amount), MW2 (drip irrigation under mulch + high irrigation amount), SM1 (shallow‐buried drip irrigation + moderate irrigation amount), and SM2 (shallow‐buried drip irrigation + high irrigation amount). The maize yields were significantly higher under mulch than under shallow‐buried drip irrigation, but there was no interaction between mulch and the irrigation amount. Drip irrigation under mulch greatly improved spring maize N, P and K uptake compared with that under shallow‐buried drip irrigation. The agronomic‐use efficiency, recovery‐use efficiency, and partial factor productivity were ranked in the order of MW2 > MW1 > SW2 > SW1. The water‐use efficiency of drip irrigation under mulch was 7.44% and 6.82% higher than that of shallow‐buried drip irrigation under the moderate and high irrigation levels, respectively. However, considering the costs of the plastic mulch, there was no significant (P < 0.05) difference in economic benefits between the SW and MW treatments. CONCLUSION Drip irrigation under plastic film provides greater advantages for production, but shallow‐buried drip irrigation may be a suitable method for farmers until fertigation technology is further optimized and the problem of plastic film pollution is solved. © 2020 Society of Chemical Industry
