Abstract

Taking the 2012 multi-point data from rice growth monitoring fields in Changzhou city as sample, the effects of planting pattern, planting density, sowing and transplanting date, application of fertilizer on the machine-transplanted rice were analyzed and summarized. The results showed that machine-transplanted rice yield is higher than direct-seeding rice, the main feature is the ears decreasing but the grain number increasing. The optimum planting density of machine-transplanted rice is 1.8×104 points per 667 m2, the optimum transplanted seedling age is 15~20 days, the optimum proportion between the basal-tiller nitrogen and earing nitrogen is 6∶4, the optimum proportion between the basal nitrogen and tiller nitrogen is 3∶7, the optimunm period of the tiller nitrogen is the second and third leaf age after transplanted. Increasing the accumulation of biological-yield between heading stage and maturity stage is the key way to increase the yield of machine-transplanted rice.
