Other claims from this paper (17)
- Observation Ammonium, available phosphorus and available potassium were mainly distributed in the 0-80 cm soil layer.
- Observation Nitrate was mainly distributed in the soil layer below 80 cm during wheat harvest.
- Intervention effect Irrigation at anthesis promoted wheat uptake of ammonium, available phosphorus and available potassium from the upper soil layer.
- Intervention effect Irrigation at anthesis promoted wheat uptake of nitrate nitrogen from the lower soil layer.
- Intervention effect Irrigation at anthesis did not aggravate deep leaching of nitrate.
- Observation Wheat roots were mainly concentrated in the 0-60 cm soil layer.
- Association Root abundance decreased with increasing soil depth.
- Observation Dry matter accumulation, total nitrogen and total phosphorus were mainly distributed in grains at maturity.
- Observation Total potassium was mainly distributed in stems.
- Intervention effect Irrigation at anthesis significantly increased 100-grain weight.
- Intervention effect Irrigation at anthesis promoted full absorption of soil nutrients by roots at late filling stage.
- Intervention effect Irrigation at anthesis delayed senescence of flag leaves after flowering.
- Intervention effect Irrigation at anthesis prolonged the functional period of nutrient transport from vegetative to reproductive organs.
- Intervention effect Irrigation at anthesis left nutrients in vegetative organs more fully transported to grains.
- Association Root morphology was negatively correlated with soil nitrate in the 0-40 cm soil layer.
- Association Root morphology was positively correlated with soil ammonium in the 80-100 cm soil layer.
- Association Root morphology was positively correlated with soil available phosphorus in the 0-100 cm soil layer.
