Opis:
This study aimed to investigate the effect of alternate furrow irrigation accompanied by biochar application within different cropping patterns on soil respiration and root traits such as root dry weight and root volume associated with the dry matter yield of sorghum (Sorghum bicolor L.) over a twoyear period (2017 – 2018). The treatments consisted of three irrigation methods, which included every furrow irrigation, fixed furrow irrigation and alternate furrow irrigation and two cropping patterns including one-row, two-rows and three levels of biochar application including 0, 6 and 12 t ha-1. Different irrigation levels had a significant effect on root morphological indices, soil respiration, and the dry matter of forage yield. Biochar application showed a significant influence on soil respiration, as the highest soil respiration was observed in the B2 and B1 treatments (0.173 and 0.171 μmol C g-1 soil h-1, respectively), in contrast, the least was observed in the control treatment B0 (0.168 μmol C g-1 soil h-1). Biochar application had a positive effect on root dry weight, root volume and dry matter yield due to the prevention of severe moisture loss and further yield loss.

Opis:
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.
