Management measures for jointing and long panicle stage of Rice
At present, the growth of rice in the city has gradually entered the stage of jointing and panicle growth, which is not only an important period for the transformation from vegetative growth to reproductive growth, but also a key period to determine yield. To do a good job in the field management of rice in the middle and later stage is very important for protecting full panicle, attacking large panicle, shaping high-yield plant type and setting up high-yield shelf. 1. Seedling characteristics according to the survey on July 21, the average leaf age of mechanically implanted rice was 12.31, 0.49 more than that of the same period last year, the average leaf age of direct seeding rice was 10.31, 0.56 more than that of last year, and the total number of tillers was 38.63.
