Other claims from this paper (10)

Intervention effect Organic materials returning fertilization increased tillers, panicles per unit area and LAI of rice.
Intervention effect Organic materials returning fertilization significantly improved rice grain yield.
Intervention effect Under NPK fertilization, leaf nitrogen content of early rice declined sharply after the tillering stage.
Intervention effect Earing fertilization of late rice could increase nitrogen uptake in the late period.
Intervention effect Organic materials returning fertilization could improve nitrogen uptake in the mid-late period.
Intervention effect The effect of organic materials returning fertilization was obviously better on early rice than on late rice.
Observation Nitrogen contents in leaves and grains of early rice were higher than those of late rice.
Association In early rice, net photosynthetic rate was significantly positively correlated with leaf nitrogen content (r=0.664).
Association In late rice, net photosynthetic rate was significantly positively correlated with leaf nitrogen content (r=0.704).
Intervention effect At a middle fertilizing level, organic materials returning fertilization could reduce NPK use by more than 1/3.
