“…Dry matter production is always positively correlated with light interception . In the growing canopy, leaf traits, such as LAI are important factors associated with the ability of leaves to collect light and photosynthesize (Yang et al, 2017). Different plastic mulching techniques also had an effect on summer maize LAI, and both LAI and grain yield had the same trend in 2016.…”

In the North China Plain, it is a matter of urgency to explore the feasibility of using biodegradable film to replace polyethylene film. A field experiment was conducted by covering soils with polyethylene white film, biodegradable white film, biodegradable black film, while the control remained uncovered. This study analysed the effects of using different film types on summer maize dry matter accumulation and transfer, grain yield and yield components during the 2016 and 2017 summer maize growing seasons. Results showed that, for both growing seasons, compared with non-mulching, dry matter translocation, dry matter transfer efficiency of vegetative organs and grain yield for plants following polyethylene white film and biodegradable white film treatments were always lower. However, dry matter accumulation, dry matter translocation, dry matter transfer efficiency, grain yield, and the contribution of dry matter translocation to grain yield before flowering in biodegradable black film treatments significantly increased by 21.0, 33.3, 21.4, 12.6, and 18.5%, respectively. Only the black biodegradable film could increase grain yield as determined by the 1000 kernel mass. Results indicate that black biodegradable films are a viable alternative to polyethylene film in summer maize production in the North China Plain.

“…Therefore, improving RUE is of great significance to the stability of crop production. Previous studies reported many factors affecting crop RUE, such as water availability (Yang, Yu, Zhang, & Shi, 2017) and crop growth characteristics including leaf area index (LAI) and height (Yang, Li, Ma, Sun, & Xu, 2014;Zhang, Zhou, & Chen, 2016). Caviglia et al (2013) attributed increased crop yield productivity to greater capture of resources, rather than improved Crop Science T A B L E 1 Basic physical and chemical properties of the soil in 0-to-200-cm depth at the beginning of the experiment in July 2016 at Xifeng, Gansu, China resource use efficiency.…”

The traditional cropping system on the Loess Plateau of China is winter wheat (Triticum aestivum L., W) monocropping. However, this cropping system, with a 3-mo summer fallow (F) period, has exhibited low radiation and precipitation use efficiency. The objectives of this study conducted in 2016-2018 was to investigate system productivity and resource (i.e., water and radiation) use efficiency when winter wheat monocropping was intensified by planting forage rape (Brassica napus L., R) during the summer fallow period. Dry matter yield (DM), water use efficiency (WUE), and radiation use efficiency (RUE) of forage rape and winter wheat in F-W and R-W crop rotations were determined. The results show that forage rape did not change system DM in all years, and winter wheat grain yield as well as DM in 2018, but decreased winter wheat grain yield and DM by 17 and 16% in 2017, respectively. Forage rape increased the system average water use (WU) by 20%, whereas system WUE of DM (WUE DM) was unaffected in both years. Forage rape also improved system intercepted photosynthetically active radiation (IPAR) by 39% but did not alter winter wheat IPAR in both years. In 2017, intensification with forage rape decreased winter wheat RUE DM and RUE of grain (RUE Grain). In conclusion, crop productivity was mainly related to water availability during sowing and the growing season, whereas RUE was related to crop productivity. Therefore, soil water supply needs to be considered before sowing forage rape during the summer fallow in the semiarid region of China as examined in this study.
