“…The maize emergence rate under treatments of MD 1 , MD 3 and MD 4 did not appear to be markedly different, but that in MD 2 decreased by 1.6-2.3%. The reason why maize in MD 2 obtained a lower emergence rate was that the PD (May 2-3) was near the date of late spring cold, the average temperature during maize sowing-VE period was lower than that in other treatments.…”

“…The late spring cold slowed down maize early growth process (MD 1 and MD 2 ), but no significant adverse effect existed on later growth. As to MD 3 and MD 4 , the occurrence of early autumn freezing at maize later stages led to significant decrease in AATs during the reproductive stage with adverse effect on grain filing and dehydration, and subsequently resulted in evident yield penalty (11.3-16.8%).…”

“…Under MD 3 and MD 4 , the bald tip length increased by 34.3% and 54.3%, the hundred-grain weight decreased by 4.3% and 9.1%, and grain number per ear decreased by 7.5% and 9.9%, respectively, compared with those in MD 1 and MD 2 . The results illustrated that delayed sowing is unfavorable for the formation of yield components.…”

“…However, the selection of planting date (PD), which corresponds to the expanded planting of crop varieties with a long GP, remains challenging [4]. In recent years, researchers have conducted extensive discussions on the changing trend of the PDs for rice, maize and other crops [4][5][6][7]. The Corn Belt in Northeast China is located in cold middle-latitude regions.…”

Given that chilling injury, which involves late spring cold and early autumn freezing, significantly affects maize growth in middle-latitude cold areas, a highly efficient cultivation technique combining suitable planting date (PD) and mulched drip irrigation is being studied to guarantee maize production. A field experiment for medium-mature variety "Xianyu 335" was conducted in 2015 to 2016 in Chifeng, Inner Mongolia, China, to explore the effects of PD on the active accumulated temperature (AAT) distribution and maize growth under mulched drip irrigation. Based on the dates (around May 1) of late spring cold occurring in the area, four PDs were designed, namely, April 20 (MD 1 ), May 2-3 (MD 2 ), May 12 (MD 3 ), and May 22 (MD 4 ), and a non-film mulching treatment (NM-D 2 ) was added on the second PD. Results indicated that: (1) the warming effect of film mulching effectively compensated for the lack of heat during the early stages of maize growth. Compared with that in NM-D 2 , the soil temperature under mulching in MD 2 for the sowing-emergence and seedling stage increased by 14.3% and 7.6%, respectively, promoting maize emergence 4 days earlier and presenting 5.6% and 9.7% increases in emergence rate and grain yield, respectively; (2) the AAT reduction caused by PD delay was mainly observed in reproductive stage, which reached 96.6 • C for every 10 days of PD delay in this stage; (3) PD markedly affected maize growth process and yield, which were closely related to the chilling injury. The late spring cold slowed down the emergence or jointing for maize (under MD 1 and MD 2 ), but brought insignificant adverse effect on maize later growth and grain yield (16.1 and 15.9 Mg·ha −1 , respectively). While the maize in both MD 3 and MD 4 treatments suffered from early autumn freezing damage at the anthesis-maturity stages, resulting in shortening in reproductive period by 4-8 days and decrease in grain yield by 11.4-17.3% compared with those in MD 1 and MD 2 ; and (4) taking the typical date (May 1) of late spring cold occurring as the starting point, the grain yield penalty reached 8.5% for every 10 days of PD delay; for every 100 • C of AAT decrease during reproductive stage, the grain yield decreased by 6.1%. The conclusions offer certain reference values for maize cultivation in the same latitude areas with similar ecological environments.

“…Because of the large range of the heat resources (14608 ; 23708C day 21 ; here we use GDD as the index, as mentioned in the previous subsection), several maturity types of maize (early maturing, midmaturing, late maturing, and so on) were commonly planted in NEC (Liu et al 2013;Zhao et al 2014). Therefore, selecting the optimal cultivars in certain climate zones is vital for maize production in NEC.…”

Northeast China (NEC) is one of the major agricultural production areas in China, producing about 30% of China's total maize output. In the past five decades, maize yields in NEC increased rapidly. However, farmer yields still have potential to be increased. Therefore, it is important to quantify the impacts of agronomic factors, including soil physical properties, cultivar selections, and management practices on yield gaps of maize under the changing climate in NEC in order to provide reliable recommendations to narrow down the yield gaps. In this study, the Agricultural Production Systems Simulator (APSIM)-Maize model was used to separate the contributions of soil physical properties, cultivar selections, and management practices to maize yield gaps. The results indicate that approximately 5%, 12%, and 18% of potential yield loss of maize is attributable to soil physical properties, cultivar selection, and management practices. Simulation analyses showed that potential ascensions of yield of maize by improving soil physical properties PAY s , changing to cultivar with longer maturity PAY c , and improving management practices PAY m for the entire region were 0.6, 1.5, and 2.2 ton ha 21 or 9%, 23%, and 34% increases, respectively, in NEC. In addition, PAY c and PAY m varied considerably from location to location (0.4 to 2.2 and 0.9 to 4.5 ton ha 21 respectively), which may be associated with the spatial variation of growing season temperature and precipitation among climate zones in NEC. Therefore, changing to cultivars with longer growing season requirement and improving management practices are the top strategies for improving yield of maize in NEC, especially for the north and west areas.

How to allocate heat resources during yield formation and grains drying in the field to ensure food security while reducing the grain moisture content (GMC) is an important issue in maize (Zea mays L.) production in China. In this study, we established three production scenarios (traditional production (TPS, GMC > 30% at harvest), mid-moisture grain harvest (MMHS, GMC ≤ 25% at harvest), and low-moisture grain harvest (LMHS, GMC ≤ 20% at harvest)). Five varieties (DMY1, FK139, DK159, XY335, and JK968) were selected as model varieties to establish a grain drying prediction model, and the model prediction accuracy was good (RMSE = 2.96-4.04%, R 2 = .408-.733). Results revealed that the production loss of the LMHS was 23.7% compared to the TPS, while the MMHS had a production loss of 6.5%. By replacing new varieties with high yield potential and fast grain drying rate, even small production increases can be achieved in MMHS. By adjusting the layout, it was possible to achieve 25% GMC in Inner Mongolia, which can promote the mechanical grain harvesting. However, the conditions for further reducing GMC (20%) at harvest are not yet available, and this requires more detailed future research.
