Abstract

Abstract: In order to explore the application effects of the new compound fertilizer Heijingdao in production, taking hybrid rice variety Longliangyou 1988 and conventional rice variety Huanghuazhan as experimental materials, two fertilizer treatments were set and used common compound fertilizer as control to analyze and compare the effects of different fertilization treatments on rice yield formation and lodging resistance by field plot experiment. The results showed that, compared with control, the effects of Heijingdao compound fertilizer could effectively increase rice yield, and the main reason was that the the number of effective panicles and 1 000-grain weight were significant increase. It can increase the number of the highest stems and the number of effective stems of rice, but the final earing rate was not much different compared with that of common compound fertilizer. The increase of stem number made the leaf area index of each growth period significantly higher than that of the control. Dry matter accumulation and crop growth of rice applied Heijingdao compound fertilizer also showed significant advantages, ensuring the formation of photosynthetic products. This compound fertilizer can significantly improve the lodging resistance-related characters in the mature stage, the ratio of internodes of rice applied Heijingdao compound fertilizer was optimized to reduce the plant height and barycenter height of hybrid and conventional rice, and increased the basal internode thickness and wall thichness of the stem, so that the flexural strength of basal internode increased and lodging index decreased.

Key words: rice（Oryza sativa L.）, new compound fertilizer, growth and development, lodging resistance, yield
