Note:ΔS，change in soil water storage during wheat season；SL，spike length；GPS，grains per spike；FT，fertile tiller；1000-KW，1000-grain weight.Different lowercase letters within a line indicate significant difference among different treatments at P<0.05.

Yield，yield components，WP and PP of the wheat crop were significantly higher in the mulched treatments than those in the control（Table 5），with an average increase in yield of 16.3%and 17.1%in 2013–2014 and 2014–2015，respectively.Grain yield was the highest in M3 at 9281 kg/hm2 in2013–2014 and 9210 kg/hm2 in 2014–2015，followed by M4 at 9105 kg/hm2 in 2013–2014 and9055 kg/hm2 in 2014–2015.Yield components in all treatments were lower in 2014–2015 than those in 2013–2014.None of the yield components exhibited significant differences between M3and M4 in the two seasons，except for numbers of fertile tillers，suggesting that the yield differences between M3 and M4 mainly due to differences in the numbers of fertile tillers（Table 6）.
