“…The improvement in the physical and chemical properties of the soil also could promote the development of crop roots (Guan et al, 2015a;He et al, 2019c). However, the increase in the bulk density was not favorable for the growth and development of wheat roots.…”

Water shortage is a serious threat to agriculture production in the North China Plain. Sustainable management practices can improve the water use efficiency of winter wheat, but currently no academic consensus has been reached. Therefore, we performed a meta-analysis that included 2194 observations from 209 articles to assess the water use efficiency of wheat in this area. The groundwater provides for 34%-37% of wheat evapotranspiration, which increases the decline of groundwater levels. The management of wheat irrigation appears to be the key process in improving agricultural water use efficiency. We observed from regression analyses that the factors such as climate, soil, and management significantly affect the water use efficiency of wheat (p < 0.05). The data showed that nitrogen input and irrigation significantly increased wheat yields (p < 0.05), but irrigation did not significantly improve the water use efficiency compared to rain-fed wheat. The optimal water use efficiency was obtained when the irrigation amount was 80-160 mm, or irrigation was applied twice, or the seasonal irrigation amount plus precipitation was ≤ 240 mm. In contrast, a nitrogen input significantly increased evapotranspiration and water use efficiency. The water use efficiency improvement was especially prominent when the nitrogen application rate was 220-250 kg•ha −1 . Moreover, subsoiling and straw return should be recommended for increasing yield, reducing evapotranspiration, and improving water use efficiency. These practices can ultimately save over 240 mm of water and 75 kg•ha −1 of nitrogen, which contributes to a sustainable agricultural development. Here, we demonstrate for the first time the impact of management practices on crop water use efficiency at a regional scale and propose a sustainable agricultural development scheme.

“…Many studies have found that the planting density of wheat is negatively correlated with the lodging resistance index; stems are gradually refined, and the length of the basal internodes increases [12]. The overall length of the stems reduces, and thus, the mechanical strength of the stems decreases [13]. Studies have shown that the planting density of winter wheat is closely related to leaf senescence and grain weight.…”

In response to the production crisis caused by a winter feed shortage due to the rapid development of the animal husbandry industry, winter rye 001 was selected to study differences in stalk and senescence characteristics in yield formation in cold regions. Five density treatments were established in a randomized design as 225 × 104 plant·hm−2 (D1), 275 × 104 plant·hm−2 (D2), 325 × 104 plant·hm−2 (D3), 375 × 104 plant·hm−2 (D4), and 425 × 104 plant·hm−2 (D5). Stem characteristics, SOD activity, POD activity, MDA content, and differences in yield and feeding quality under different population densities were analyzed. The plant height, center of gravity, and stem basal internode length showed an increasing trend with an increase in planting density. The stem wall thickness, diameter, strength, and lodging resistance indices decreased. At 275 × 104 plants·hm−2, the rye crude protein content was the highest while neutral washing fiber and acid washing fiber were the lowest, and feed quality was the best. With an increase in density, spike number, grain number per spike, and thousand-grain weight first increased and then decreased. We concluded that the yield and feeding quality were best when the basic seedling was at 275 × 104 plants hm−2.

“…Cd is one of the most toxic heavy metal elements that harmful to the growth of plants and human health [1]. As a component of soil, the activity of enzyme can sensitively reflect the direction and intensity of biochemical reaction in soil [2]. The distribution of heavy metal ions in soil will affect soil enzyme activity, and it is feasible to detect soil heavy metal contamination with soil enzyme activity [3].…”

The effects of intercropping with four hyperaccululator plants Galinsoga parviflora, Sigesbeckia orientalis, Solanum nigrum and Crassocephalum crepidioide on soil enzyme activity and soil organic matter of grape seedlings under cadmium (Cd) stress were studied by a pot experiment. The results showed that intercropping with C. crepidioide and the monoculture had no significant differences in soil organic matter, but other treatments were higher than the monoculture. Compared to the monoculture, urease and catalase activities were increased by intercropping with C. crepidioide, but the activities of invertase and phosphatase were decreased. The other intercropping treatments on soil enzyme activity were higher than the monoculture, and intercropping with S. orientalis was the best.
