“…This finding is consistent with previous studies on straw incorporation and yield stability [16,27,28]. This result might be because straw incorporation could improve soil fertility, increase root bacterial communities, and promote rice root growth and nutrient absorption [16,25,[38][39][40]. In our experiment, RBITS increased the content of soil organic matter, total N and available K (data not shown), and had a higher positive effect on K concentration and absorption under Low-DTL than under High-DTL.…”

“…Under low temperature and light conditions, weakened rice transpiration might inhibit K uptake by the pathway of mass flow (depending on transpiration pull). Huge root systems and strong root vitality in straw incorporation [39,40,43] might cause the dominance of root interception of K under poor weather conditions, promoting K uptake and enhancing the resistance of crops to abiotic stresses. Increasing crop K concentrations could promote the development of vascular bundles in stems, and then promote the transportation of substances and N to the panicle [16,18,19].…”

A reduced basal and increased topdressing fertilizer rate (RBIT) can usually increase rice yield, but whether this practice alleviates the impact of poor weather on rice production is unknown. Thus, the effect of three integrated RBIT treatments (RBITs, including RBIT alone, RBIT in combination with straw incorporation (RBITS) or a reduced fertilizer rate (RBITR)) on rice growth and nutritional status under different weathers was investigated in a 9-year experiment. Conventional fertilization (CF) was the control. We found that daytime temperature and light (DTL) after heading were the main meteorological factors limiting rice yield increases. RBITs did not affect rice yield under High-DTL, compared with CF, but RBITS significantly increased rice yield under Low-DTL. Compared with High-DTL, the positive effect of RBIT and RBITR on the N concentration and proportion in vegetative organs under Low-DTL was higher than the K concentration in vegetative organs, but RBITS showed the opposite trend. Regression analysis indicated that the harvest index had stronger correlations with the N concentration (negative), K concentration (positive), and N/K (negative) in vegetative organs under Low-DTL than under High-DTL. Our findings suggested that RBITS could improve rice adaptability to daytime temperature and light changes after heading by balancing crop nutritional status (N/K).

“…During the deposition of nitrogen that was absorbed by the rice leaves and plants under the influence of unfavorable factors, such as evaporation and a loss in the paddy environment, the TC and TN content of the soil did not increase significantly. In addition, in the early season, the soil TP content significantly increased under N deposition, agreeing well with the previous study [32]. Perhaps it was because N deposition stimulated an increase in the soil S-ACP activity (Figure 2A), which decomposed the soil organic matter (SOM) and released the P element.…”

There have been few studies on the impact of nitrogen deposition on paddy field ecosystem; therefore, we evaluated the effects of different N deposition levels (0, 40, and 120 kg N·ha−1) with the conventional nitrogen rate (180 kg N·ha−1) on rice field ecosystem through two-season experiments. The results showed that 40 and 120 kg·ha−1 nitrogen deposition had no significant effect on rice yield, although the rice grains per panicle and the 1000-grain weight increased. The 40 and 120 kg·ha−1 nitrogen deposition levels had no significant effect on rice and soil total carbon/total nitrogen (TC/TN) in the two-season experiment; however, 40 and 120 kg·ha−1 nitrogen deposition significantly increased TP content of the rice root and soil in a short time, and continuous 120 kg·ha−1 nitrogen deposition significantly decreased TP content of the rice root and significantly increased TP content of the rice stem. In addition, nitrogen deposition significantly reduced total carbon/total phosphorus (TC/TP) and total nitrogen/total phosphorus (TN/TP) in the soil. The activities of soil acid phosphatase (S-ACP), β-glucosidase (S-β-GC), and N-acetyl-β-D-glucosidase (S-NAG) increased under 40 kg·ha−1 nitrogen deposition, while the activities of S-β-GC and S-NAG decreased under 120 kg·ha−1 nitrogen deposition compared with 40 kg·ha−1. The microbial carbon, microbial nitrogen, microbial phosphorus, and fungal microbial biomass reduced under 40 and 120 kg·ha−1 nitrogen deposition. These findings suggest that, under short-term N deposition, rice and soil can adjust the C, N, P, and even the nutrient balance by themselves; however, continuous nitrogen deposition may have adverse reactions to microorganisms, thereby disrupting this balance and ultimately leading to the deterioration of paddy soil environment and a reduction in rice yield in the long term.
