Abstract:

Facing the increasing water shortage in North China, new techniques for high-yield and less irrigation are urgently needed in winter wheat production. A 10-year successive field experiment was carried out from 2007 to 2016 to clarify the effects of soil water storage before sowing and effective precipitation in wheat growth duration on the yield-increasing efficiency of supplementary irrigation at flowering stage, as well as the interaction of irrigation with nitrogen (N) application rate. The objective of the study was to propose an applicable standard of irrigation for winter wheat in North China Plain. The plots were arranged in a split-plot design with the main factor of irrigation amount and sub-factor of N rate. On the condition that 75 mm water was given at jointing stage of wheat, the main-plots were assigned with supplementary water of 0 (W1) and 75 mm (W2) at flowering stage. The sub-plot treatments were N rate of 0 (N0), 60 (N60), 120 (N120), 180 (N180), 240 (N240), and 300 kg hm -2 (N300). The yield-increasing ratio of supplementary irrigation at flowering stage was negatively correlated (P < 0.05) with the water storage in 2 m soil body before sowing and influenced by soil N level. The soil organic matter and total N content of N0 and N60 declined gradually with the years of experiment, and no positive effect of W2 on yield was observed since the sixth year. Under the condition of adequate soil water before sowing and normal nitrogen supply (at least 120 kg hm -2), the effect of W2 on yield was also influenced by the effective precipitation during wheat growth, especially that from jointing to flowering stage. The yield-increasing ratio of W2 decreased with the increasing effective precipitation in wheat growing period. When the effective precipitation from jointing to flowering stage was more than 25.3 mm, W2 had no significant advantage on spike number, grain number per spike, 1000-grain weight, biomass, harvest index, and final grain yield, indicating that irrigation of 75 mm at jointing stage was available for water-saving, high water use efficiency and high yield level. In conclusion, under the condition of well soil water content before sowing, N application rate ≥120 kg hm -2 and irrigation at jointing stage, the effective precipitation from jointing to flowering might be considered as an important criterion to determine the necessity of supplementary irrigation at flowering stage of winter wheat in North China Plain.

Key words: winter wheat, irrigation regime, water and nitrogen coupling effect, North China Plain, high-stable-yield
