Effects of fertilizer types and dosage on rice growth and yield
In order to explore the effects of different fertilizers and their dosage on rice growth,yield and quality,such as chemical fertilizers,organic fertilizers,and active silicon calcium fertilizers were selected,and multiple fertiliza-tion and dosage schemes(no fertilization,conventional fertilization,optimized fertilization,organic-inorganic fertilizer combination,and active silicon calcium fertilizer)were seted up to explore the application effects of fertilizer types and dosages in rice production.The results showed that the grain filling rate of rice reached a high level under the combina-tion of organic-inorganic fertilizers and silicon calcium fertilizers,and a longer grain filling time was beneficial for grain formation.The photosynthesis of rice was weaker under two treatments of no fertilization and silicon calcium fertilizer,while the photosynthesis ability was stronger under the other treatments,which was conducive to the accumulation of organic matter.The ranking of rice yield from high to low,they were combined application of organic and inorganic fer-tilizers>conventional fertilization>active silicon calcium fertilizer>optimized fertilization>no fertilization.The rice qual-ity were at an optimal level in both conventional fertilization and the combination of organic and inorganic fertilizers.Overall,it is recommended to use a combination of organic and inorganic fertilizers for rice cultivation,which is benefi-cial for promoting the growth and development of rice,and improving yield and quality.
