“…The results were similar to the split root system, in that both the plant growth and yield were higher with unequal salinity distribution than with equal salinity distribution, because plant roots were able to take up enough water from soil in the low-salinity environment [34]. In the Yellow River Delta of China, Dong et al [49] also found that RF could increase stand establishment and lint yield of cotton in a saline field.…”

“…Plastic film mulching has proved to be an effective measure to increase soil temperature and to reduce evaporation as well as to prevent salt accumulation [49,50]. However, according to Li et al [51], the temperature under mulch could reach to more than 50 • C at 14:00 during the daytime, and the seedlings might be burned or killed in such a high-temperature environment.…”

Flat (F), mini-ditch (MD), and ridge-furrow (RF) are three conventional cotton planting patterns that are usually adopted around the world, yet soil and crop responses to these three patterns are poorly studied, as is their suitability for increasing yield for coastal areas in Eastern China. The effects of three planting methods on water and salt dynamics as well as on growth and lint yield of cotton (Gossypium hirsutum L.) were investigated in a saline field in Bohai Rim, China, to select the best planting pattern for cultivating coastal saline fields of Eastern China. Soil moisture in the root zone with RF was 11.9% and 12.1% higher than with F and MD, whereas the electrical conductivity of a saturated soil extract (EC e ) in the root zone with RF was 18.0% and 13.8% lower than with MD and F, respectively, during the growth period, which indicated that RF could efficiently collect rainfall and leach salt in the root zone. After drip irrigation, the infiltration and salt-leaching depth with RF were both deeper than that with F and MD. The stand establishment of MD was the highest (80.3%) due to the greenhouse effect from film mulching, and was 12.8% and 4.6% higher than that with F and RF, respectively. Growth indicators and lint yield demonstrated that RF was superior to F and MD because of the higher soil moisture and lower EC e . The lint yield was significantly higher in RF, suggesting that RF can be an optimal planting pattern for agricultural reclamation in similar saline-alkaline areas around the world.

“…These changes can enhance or reduce the salt effects on physiological responses, and further affect plant growth and development (de Lacerda et al, 2005;Dong et al, 2008). So crop productivity in saline environment depends on not only its tolerance to salt stress but also capacity to recover from salt RESEARCH stress.…”

Crop growth in a saline environment depends on its tolerance to salt stress and capacity to recover after salt stress relief. To evaluate recovery mechanisms in cotton after salt stress relief, the changes of plants growth, root vigor, lipid peroxidation, antioxidant enzymes activity, organic solutes in root after salt stress relief were studied for two cotton (Gossypium hirsutum L.) cultivars (Lumianyan 37 and Sumian 22) grown under control (salt content of soil grown cotton was maintained at 0.2%), salt stressed (salt content of soil grown cotton was maintained at 0.5%) and salt recovered (salt content of soil grown cotton was reduced from 0.5% to 0.2% level at the 57 d after seeding) conditions. The results showed that root and shoot growth rate and root vigor significantly increased after salt stress relief, and the increase in growth rate and root vigor was more pronounced in 'Lumianyan 37'. In salt-recovered root, malondialdehyde (MDA) content decrease, the activities of superoxide dismutase (SOD) and peroxidase (POD) decreased, but catalase (CAT) activity increased compared with those in the salt-stressed root. For salt-recovered root, MDA content and POD activity of 'Lumianyan 37' was lower, while the SOD and CAT activities were higher. Salt-recovered cotton root showed a decrease in soluble sugar and free amino acid content compared with the salt-stressed root, especially in 'Lumianyan 37'. The results indicated that growth and root metabolism of cotton plants gradually recovered after salt stress relief, and the high capacity of cotton plants to recover after salt stress relief may be related to the high capacity of antioxidative system and the high utilization capacity of organic solutes as important nutritional components in root.

“…Plastic film mulching has been a common agricultural practice since it was introduced to China in 1978 (Dong et al 2009, Zhang et al 2012. Polyethylene (PE) film mulching can conserve soil moisture and raise soil temperature (Dong et al 2008), promote growth and increase yields (Li et al 2004, Dong et al 2009). In peanut production, clear plastic film is the most commonly used, however, higher temperature under the clear mulch during pod development may restrict pod and kernel growth (Reddy et al 1988), and weed control also could be a problem (Waterer 2000), which will reduce the pod yield.…”

A two-year field experiment was conducted to investigate the effects of colored polyethylene (PE) films on weed control, soil temperature and moisture, and pod yield of peanut. By setting a clear PE film (CF) as control, three colored PE films were studied: black-clear-black color-matching film (BCF), silver grey film (SF) and black film (BF). The colored PE films were effective in controlling weeds compared with CF, while BF had the optimal weed control effect. Compared with CF, the colored PE films were not sensitive to air temperature, and had smaller daily temperature variations. Soil moisture at 0-40 cm depth was higher mulched with the colored PE films than those with CF, and the highest moisture occurred in BF. Peanut covered colored PE films remained higher chlorophyll content and net photosynthetic rate in the late growth stage. Compared with CF, the pod yields with BCF, SF and BF were significantly increased by 12, 7, and 5% in 2012, and 14, 10, and 5% in 2013, respectively. The treatments of SF and BCF get higher yields in 2012 and in 2013. Accordingly, SF and BCF may be better field-management options for weed control and high yield in peanut field. Keywords 79Plant Soil Environ. Vol. 61, 2015, No. 2: 79-85 Experimental design. A randomized complete block design with three replications was used with four kinds of PE films mulching including clear PE film (CF) as control, black-clear-black color-matching film with the 25 cm clear band in middle of the film (BCF), silver gray film (SF), and black film (BF), all films are 0.008 mm thick and 90 cm width. Alternating ridges (50 cm wide and 15 cm high) and furrows (50 cm wide) were used with only the ridges mulched with film. Two rows of peanut were sown with two seeds in one hole in each ridge on 1 May 2012 and 4 May 2013 with 25 cm row-spacing and 16 cm seed spacing, and the density is 125 000 holes/ha. The peanut cultivar is Huayu 22. Each plot was 3 × 10 m 2 . The peanut was harvested on 8 September 2012 and 10 September 2013. Before ridging, 500 kg/ha of triple compound fertilizer (15% N-4.3% P-8.3% K) were applied, and there were no irrigation and herbicide during the whole growth period.Soil measurements. Soil temperatures at 5 cm and 10 cm depth were measured with thermometer during the pod setting and filling stage at 8:00, 14:00 and 20:00. At the same time, soil moisture was measured at 20 cm intervals to a depth of 40 cm by gravimetric method (Black 1965).Weed control assessment. The species and density of weeds were collected in 1 m 2 at three random locations per plot when peanut was harvested. All weeds were identified, counted and recorded for the species and density calculation referred to the China's farmland weed color map (Tang 1989). The total weed biomass was determined after drying at 105°C for 30 min initially and then at 75°C for 48 h (Zhang et al. 2011).Growth parameters. Photosynthesis rate was determined by using a portable photosynthesis meter (LI-6400XT, LI-COR, Lincoln, USA) at the four growth stages (flowering, ...
