Management Measures and Technical Points for Rice during the Jointing and Panicle Elongation Stage
The jointing and panicle elongation stage refers to the period from jointing and the beginning of young panicle differentiation to just before heading, generally 25-36 days for middle-season rice. 1. Growth and development characteristics and growth appearance during the jointing and panicle elongation stage (1) Growth and development characteristics During this period, on the one hand, stem elongation is the center, completing the growth of the last few leaves and root system and other vegetative organs; on the other hand, reproductive growth centered on young panicle differentiation takes place. During this period some tillers gradually die, and the total number of stems and tillers declines compared with the earlier stage, so it is an important period for preserving tillers and increasing panicles.

Cold damage prevention and control methods and key technical points for rice at the panicle elongation stage
Rice pollination at the panicle elongation stage greatly needs temperature and oxygen. During this period, cold winds blowing from the northeast are very likely to occur, causing poor pollination, empty and shriveled grains, and reduced yield. Prevention and control techniques for cold damage. First, accelerate rice pollination. From late July to early and mid-August, due to meteorological causes of atmospheric circulation, the temperature generally drops to around 17, causing rice flowers to remain closed and not open, affecting rice pollination and producing empty and shriveled grains. For this kind of obstructive cold damage, scientific management of the paddy field should be strengthened so that rice accelerates through the pollination period and avoids
