“…Conversely, rainfall was insufficient in 2013/14, thus creating significant differences in RH between the planting patterns. The 3 years of experimental results showed that the twin row precision planting pattern increased RH and decreased soil temperature, which reduced soil water evaporation and maintained moisture levels (Wang et al 2016). Soil water content has a positive correlation with grain yield.…”

“…Environmental factors such as light, water, soil temperature and relative humidity (RH) can affect crop growth (Wang et al 2015). Wang et al (2016) demonstrated that furrow planting and irrigation had a significant effect on ET , WP and grain yield. Therefore, the microclimate of winter wheat farmland utilizing deficit irrigation and various planting patterns should be investigated by applying precision sowing.…”

SUMMARYThe production of winter wheat (Triticum aestivum L.) is affected by crop population structures and field microclimates. This 3-year study assessed the effect of different precision planting patterns and irrigation conditions on relative humidity (RH), air and soil temperature within the canopy, intercepted photosynthetically active radiation (iPAR), evapotranspiration (ET), water productivity (WP) and grain yields. Field experiments were conducted from 2011 to 2014 on a two-factor split-plot design with three replicates. The experiments involved three precision planting patterns (single row, alternating single and twin rows [hereafter ‘single–twin’] and twin row) and three irrigation treatments (0 mm (I0), 90 mm (I90) and 180 mm (I180)). Planting patterns and irrigation treatments exerted a significant effect on RH, air and soil temperature, iPAR, ET, WP and grain yield. The lowest RH and iPAR levels were detected in the single row pattern. When the irrigation treatment was identical, the highest soil and air temperatures were detected in the single row pattern, followed by the single–twin row and twin row patterns. Compared with the single row, the single–twin and twin row patterns increased ET by 0·3 and 1·4, WP by 4·7 and 5·7% and yields by 6·0 and 7·9%, respectively. Compared with I0, the I90 and I180 irrigation treatments increased ET by 0·3 and 1·4%, and WP by 4·7 and 5·7%, respectively. The grain yields of the twin row pattern were 5·8 and 1·7% higher than those of the single row and single–twin row patterns, respectively. Compared with I0, I90 increased yield by 19·3%. The twin row pattern improved crop structure and farmland microclimate by increasing RH and iPAR, and reducing soil and air temperatures, thus increasing grain yield. These results indicated that a twin row pattern effectively improved grain yield at I0. On the basis of iPAR, WP and grain yield, it was concluded that a twin row pattern combined with an I90 irrigation treatment provided optimal cropping conditions for the North China plain.

“…Water stress induced a decrease in the leaf water status such as leaf relative water content (LRWC), leaf water potential (Lψ), leaf osmotic potential (Lπ), radiation use efficiency (RUE), and yield components and grain yield (Chowdhury et al., 2011) while increased the leaf abscisic acid (ABA) content (El‐Hendawy et al., 2019; Saradadevi et al., 2014). Nevertheless, considering the efficient use of limited water in NCP, the optimal deficit irrigation of winter wheat varies greatly, for instance, 60 mm (Fang et al., 2018), 75 mm (Ali et al., 2019), 135 mm (Wang et al., 2016), 165 mm (Dar et al., 2017) and 263 mm (Li et al., 2019), which there is no uniform optimal irrigation standard yet until now. The results of several investigators also indicated that irrigation frequency had great effect on winter wheat yield and WUE (El‐Hendawy et al., 2008; Pahlavan‐Rad et al., 2011; Tunio et al., 2019).…”

Drought and water shortages have always been great challenges for agricultural production in the North China Plain. To explore appropriate irrigation regimes and planting patterns in this area, a field experiment was conducted for winter wheat (Triticum aestivum L.) from 2014 to 2016. Three irrigation treatments of 50 mm irrigation at growth stage of jointing (GS34) and heading (GS48, W1), 100 mm irrigation at GS34 (W2) and 100 mm irrigation at GS34 and GS48 (W3) combined with uniform (U), double-double (DD) and furrow-ridge (F) planting patterns were designed. The tillers number, leaf water status, spike characteristics and radiation use efficiency (RUE) were measured. Results showed that compared with W2, W3 significantly reduced leaf abscisic acid (ABA) content and increased tillers number, spikelets spike −1 , yield components and RUE, while W1 produced more tillers number, leaf relative water content (LRWC) and water potential (Lψ) only in the late growth stage, yield components and RUE. The DD significantly increased tillers number, LRWC, Lψ, leaf osmotic potential, spike length, spikes m −2 , grains spike −1 and RUE, and reduced the ABA content compared with U. Considering the serious water shortage in the North China Plain, 50 mm irrigation at jointing and heading stages combined with DD is a worthy cultivation measure for sustainable agriculture at water-deficit condition.

“…Row spacing is an important agronomic measure that determines plant spatial distribution, which affects plant canopy structure, and dry matter production; thus, row spacing ultimately influences biomass production (Mattera et al, 2013). Reasonable planting patterns are beneficial for improving the microclimate of farmlands and promoting the growth and development of crops (Wang et al, 2016). Han et al (2016) have shown that a wide-precision planting pattern results in higher winter wheat photosynthetic capacity compared with the conventional cultivation planting patterns.…”

With the shortage of water resources in recent years, water has become an important factor that limits the photosynthetic capacity and grain quality of winter wheat in the North China Plain. The experiment was conducted in 2011-2014, and the design of the two-factor split-plot was adopted, with three irrigation levels (0, 90, and 180 mm) for the main plot and three planting patterns (single-single row, single-double row, doubledouble row) for the subplot. The chlorophyll content index, net photosynthetic rate, and dry matter weight of winter wheat at different growth stages were measured, and the quality parameters of the grain were also measured after the harvest. The result indicated that irrigation increased the chlorophyll content index, net photosynthetic rate, grain protein, coarse starch and whiteness, which were favourable for producing dry matter and for seed formation. The chlorophyll content index, net photosynthetic rate, dry matter weight and gluten index of double-double row were higher than those of single-single row. Therefore, the 90 mm irrigation combined with the double-double row planting pattern is a good agronomic practice for winter wheat production, and beneficial for the improvement of flour quality in the North China Plain.
