“…This solves the apparent contradiction between individual studies reporting similar effects of FM and PM, 20,33 and others reporting superior results with FM over PM in years with sufficient water supply during the later stage of crop growth. 10,19,34,35 This may be partially because FM improves soil hydrothermal conditions at the beginning of crop growing season, 9 which speeds up soil water consumption and benefits biomass accumulation. Higher biomass early in the season may lead to drought stress at later growth stages, 36 especially during the critical flowering period.…”

“…This has been previously observed by others. 10,19,34 A recent meta-analysis found that FM had higher ET than PM across crops in the Loess The solid lines are based on French and Schultz 27 frontier concept ( wheat: x-intercept = 45 mm and slope = 26 kg grain ha −1 mm −1 ; maize: x-intercept = 50 mm and slope = 45 kg grain ha −1 mm −1 ).…”

“…4 Plastic film mulch has been widely adopted in the Loess Plateau because it is a simple and effective practice to increase yield and water use efficiency (WUE, yield per unit evapotranspiration) of crops including wheat, maize, and potato. [5][6][7][8] Plastic film mulch increases rainfall collection, especially small events (< 5 mm), reduces soil evaporation, and can improve soil thermal condition promoting crop growth, 9,10 thus, returns higher yield and WUE gains than other water saving practice, such as straw mulch. 11,12 Plastic film mulch can be partial (at least 50% soil cover) or full (complete soil cover).…”

“…18 However, the comparisons of yield and WUE in PM and full-film mulch (FM) are inconsistent. 10,19,20 This article presents a meta-analysis comparing yield, water use, and WUE of wheat and maize under PM and FM in the Loess Plateau. We hypothesized that (a) the improvement in crop yield and WUE are similar for PM and FM, and (b) the benefits of these practices vary with environmental conditions, such as precipitation, elevation, and soil type.…”

BACKGROUND: Plastic film mulch is widely used to improve crop yield and water use efficiency (WUE, yield per unit evapotranspiration) in semi-arid regions. It is commonly applied as partial-film mulch (PM: at least 50% soil cover) or full-film mulch (FM: complete soil cover). The PM has lower economic and environmental cost; hence it would be a superior technology provided it delivers similar gains in yield and WUE in relation to FM. RESULTS: To solve contradictory results from individual studies, we compared FM and PM in a meta-analysis of 100 studies with 1881 comparisons (685 for wheat; 1196 for maize). Compared with bare ground, FM and PM both increased yield of wheat (20-26%) and maize (37-52%), and WUE of wheat (16-20%) and maize (38-48%), with statistically undistinguishable differences between PM and FM. The increases in crop yield and WUE were stronger at elevation > 1000 m, with annual precipita-tion<400 mm, and on loess soil, especially for maize. CONCLUSIONS:We concluded that partial-film mulch could replace full-film mulch to return similar yield and WUE improvement, with reduced cost and environmental pollution.

Background: Traditional irrigation methods in protected vegetable production such as furrow irrigation result in low water use efficiency. New techniques, such as drip irrigation, micro-sprinkling irrigation have been developed for improving water use efficiency. However, these techniques have not been tested in greenhouse celery production. In this study, three different irrigation techniques micro-sprinkler irrigation (MS), furrow irrigation under plastic film mulching (PF) and micro-sprinkler irrigation under the plastic film mulching (MSP) were investigated whether the three techniques can improve the yield, quality and water use efficiency of greenhouse-grown celery, compared to furrow irrigation (FI). Results: The individual plant weight of celery was higher under MS, PF and MSP than under FI in both autumn season crop (AC) and spring season crop (SC), compared to FI. In AC and SC, the economic yield of celery increases under MSP by 54.18% and 49.55%, the economic yield of celery increases under PF by 30.37% and 34.10%. The irrigation amount of MSP was 151.69 and 179.91 m3 667 m-2 in AC and SC, which was 23.13% and 27.27% lower than that of FI. The irrigation amount of PF was 151.69 and 196.78 m3 667 m-2 in AC and SC, which was 23.13% and 20.45% lower than that of FI. PF and MSP reduced the irrigation amount of celery cultivation in greenhouse, and soil evaporation content. Conclusions: In short, MSP and PF promoted the growth and yield of celery in greenhouse with improved quality and water use efficiency.

This study was aimed to alleviate water deficiency and improve soil fertility in orchard in semi‐arid region. The Brassica napus L. winter varieties (including the variety V6, V7) generally had higher aboveground biological yield, lower root yield and main root length compared to the Brassica campestris L. winter / spring varieties. By mulching root area of apple tree with aboveground part of these rape varieties at later autumn, the water contents in 0‐20, 20‐40, 40‐60 cm soil were enhanced /changed at following March and positively correlated with the mulching‐plant biomass. Similarly, under treatments of the V6‐I, V7‐I (the variety V6, V7 mulching), and the V6‐II, V7‐II (mulching with aboveground part of the V6, V7 + 5% soil), the average water content in 0‐150 cm soil was significantly increased by about 12%, 9%, 18%, and 14% at following spring, respectively; meanwhile the treatment V6‐II, V7‐II induced significant increase of water contents in 0‐25, 25‐50, 50‐75, 75‐100, 100‐125, and 125‐150 cm soil profile; these treatments were conducted over two years, respectively the available K, total N, and organic matter in 0‐20 cm soil was significantly increased by 39.3%‐151.8%, 10.0%‐17.9%, and 22.7%‐34.2%, the apple tree growth was promoted, the fruit yield per plant was significantly enhanced by 16.9%‐95.5%. In conclusion, the Brassica napus L. winter variety mulching, especially the mulching with aboveground part of the Brassica napus L. winter variety + 5% soil, showed significant effect in improving soil moisture, soil fertility, and fruit yield in orchard in semi‐arid region.This article is protected by copyright.
