Other claims from this paper (15)
- Observation In drip-irrigated spring wheat, root length density and root weight density were greater at 0-20 cm than at 20-40 cm soil depth at flowering.
- Intervention effect In the shallow soil layer, root length density was greater under the D1 and D2 irrigation intervals than under D3.
- Intervention effect In deep soil, root length density did not differ among treatments with different irrigation frequencies.
- Intervention effect At 0-20 cm depth, root length density under the W3 water amount was 17.9% greater than under W2.
- Intervention effect At 0-20 cm depth, root length density under the W3 water amount was 53.8% greater than under W1.
- Intervention effect At 20-40 cm depth the root length density trend across water amounts was opposite to that at 0-20 cm.
- Intervention effect The root-shoot ratio was significantly higher under D2 than under the other treatment.
- Intervention effect Root length density and root weight density were significantly greater under D3.
- Intervention effect Leaf Pn and LAI were significantly greater under D3.
- Intervention effect Leaf Pn and LAI both increased as the irrigation amount increased.
- Association Regression showed a natural logarithmic relationship between root weight density and aboveground biomass (R2 > 0.60, P < 0.05).
- Association Root weight density at 0-20 cm depth had a binomial relationship with grain yield (R2 = 0.43, P < 0.05).
- Association Root length density at 20-40 cm depth had a binomial relationship with grain yield (R2 = 0.34, P < 0.05).
- Intervention effect With the optimum irrigation amount (W2), increasing drip irrigation frequency can increase wheat root length and root weight.
- Intervention effect With the optimum irrigation amount (W2), increasing drip irrigation frequency improved wheat yield and water use efficiency.
