Other claims from this paper (8)
- Intervention effect W4N2 significantly decreased chlorophyll content, Pn, gs, PSII efficiency and qp at full flowering versus common drip irrigation.
- Intervention effect W4N2 inhibited aboveground dry matter accumulation versus common drip irrigation.
- Association From full flowering to boll opening, chlorophyll content, gs, Pn, PSII efficiency and qp rose with increasing water and nitrogen supply.
- Association Increasing water and nitrogen supply enhanced aboveground dry matter accumulation by compensation.
- Mechanism Compensatory accumulation benefited photosynthate movement to seed cotton.
- Observation For Xinluzaol3, seed cotton yield was highest under W3 with basal 20% N and topdressing 80% N.
- Observation For Xinluzao43, seed cotton yield was highest under W4 with basal 20% N and topdressing 80% N.
- Recommendation The authors recommend reducing early water and nitrogen supply and increasing middle and late supply to extend photosynthesis and promote reproductive allocation.
