Effects of Seed-pelleting on Biochemical Characteristics of Rice

Abstract

The effects on different planting methods and different proportion of pelletized wrapping material on physiological indexes of different rice varieties were studied, providing theoretical basis for rice direct seeding cultivation in northern China. Taking the Japonica rice varieties (Longyou 619) as materials, cultivating in Shenyang Institute of Technology field practice base. The experiment was divided into six treatments, respectively, control groups (ck: only soil, no fertilizer), group T1-80:1, group T2-90:1, group T3-100:1, group T4-110:1, group T5-120:1. We studied the optimum soil fertilizer ratio in different seeding methods and the changes of physiological indexes of rice. Different seeding methods and soil fertilizer ratio has different effects on rice pelleting, for it, drilling was compared with hill-drop, drilling was more suitable for rice seed planting, Chlorophyll and nitrogen, phosphorus and potassium content, and some physiological indexes of rice leaves were so higher, and the pelletized seeds’ physiological indexes were higher than upelletized seeds’, rice grew and developed differently under different soil fertilizer ratio. For rice variety Longyou 619, the most suitable seeding method was drill sowing, the best ratio of soil to fertilizer was group T3 which was equal to 100:1, Chlorophyll content in the whole group was high, nitrogen, phosphorus and potassium content in leaves was also high, the dry matter accumulation in the growth period was higher than the other two planting methods, it is more suitable for the Longyou 619 planting.
