Abstract
Different cultivation patterns affect the grain yields of winter wheat by regulating growth and development. In this study, the growth of wheat was observed for two years (2008‒2009 and 2009‒2010). We established three cultivation patterns: 25 cm uniform row planting pattern; “20 cm + 40 cm” wide-narrow row planting pattern (wide-narrow row spacing is 40 cm and 20 cm respectively); and “20 cm + 40 cm” furrow planting pattern (double lines in the furrow with 20 cm spacing, 40 cm between furrows, and ridge height of 15 cm). Three irrigation treatments viz. 90, 135 and 180 mm were established. Results showed that furrow planting pattern improved the ratio of variable over maximum fluorescence (Fv/Fm).With increasing irrigation amount, Fv/Fm increased, the amplification declined, and the net photosynthetic rate in flag leaves increased. However, such effect was not obvious beyond the irrigation range stipulated. Therefore, we recommend the furrow planting pattern, which resulted in stable yield and 135 mm deficit irrigation as optimum considering the water shortage in the area. © 2016 Friends Science Publishers
