\u3000On the other hand, the factors that caused the decrease in thousand-grain weight were excessively high temperature during the ripening period, low rainfall frequency and amount, and significantly many days with low minimum humidity, resulting in a decrease in leaf color of the rice plants (decrease in leaf color of lower leaves that supply photosynthetic products to the roots), decrease in water absorption capacity of the roots, and decrease in cytokinin (hormone that inhibits chlorophyll degradation in the leaf blade) produced by the roots, which reduced the photosynthetic capacity of the rice plants and decreased thousand-grain weight. The decrease in the amount of cytokinin (a hormone that inhibits the decomposition of chlorophyll in the leaf blade) produced by the roots reduced the photosynthetic capacity of the rice plants, resulting in lower thousand-grain weight and increased occurrence of \"basal immature grains,\" which are determined in the latter half of the ripening stage in terms of quality. It is considered that the more severe the decrease in leaf color was, the more \"basal immature grains\" increased, resulting in a decrease in quality.<\/p>\n\n\n\n

\u3000For each cultivar, the larger the decrease in leaf color (lower leaves and mortality rate) in the second half of the ripening period, the lower the yield and the greater the quality loss (Table 5). Setsuwakamaru, which is considered to be more tolerant to high temperatures, tended to have a lower percentage of lower leaves dying and less quality loss.<\/p>\n\n\n

\u3000The above results suggest that under high temperature ripening conditions, a decrease in leaf color after the middle of the ripening period causes rice body senescence, which contributes to quality and yield loss, and that a small-quantity, frequent nitrogen fertilizer application is extremely effective in reducing quality loss under high temperature conditions by using a surface fertilizer that is absorbed by the \"upper roots. However, it is difficult to implement the above-mentioned small-quantity, multiple-fertilizer application under the current circumstances where the production system is expanding in scale and the number of farmers is decreasing and aging.<\/p>\n\n\n\n

\u3000This suggests that the continuous supply of nitrogen by \"leave it to the seedling box\" maintains the leaf color of the lower leaves, which supply photosynthates to the roots, and that cytokinin (a hormone that inhibits chlorophyll degradation in the leaf blade) produced by the roots is also supplied to the aboveground area, maintaining a high rate of root emergence (water absorption), increasing nitrogen absorption, and improving photosynthesis rate in the leaf blade, resulting in higher yield and quality (Figure 9). This is thought to increase the rate of photosynthesis of the leaf blade, resulting in improved yield and quality (Fig. 9).<\/p>\n\n\n

\u3000In the same cultivar, damage was reduced in plots where leaf color (especially the third leaf from the top) was maintained until late in the ripening period, soil preparation was implemented, appropriate water management was implemented (e.g., to cope with fading), and root mass was secured. Therefore, in this era of high temperatures, the application of siliceous materials, reduction of reduction risk, rooting, and proper water management are essential technologies that need to be further promoted.<\/p>\n\n\n\n

0Securing the mature roots is important, and the number of cases of late wilting caused by roots is increasing. It is necessary to secure the \"nadir root\" and \"upper root,\" which are the roots that mature (securing the roots by appropriate drying out and intermittently irrigating). This is fatal under high temperature conditions.<\/p>\n\n\n\n

0Under high temperature conditions, the application of siliceous materials is essential as fertilizer because silicic acid improves light-reception (increased leaf erectness), increases specific leaf weight (leaf blade thickness), improves root oxidation (increased water absorption), and promotes transpiration by opening pores (decreased rice body temperature). Since the risk of field reduction is increasing, steel slag-based siliceous materials containing iron oxide are useful. Rice with low silicon content \u21d2 reduced transpiration \u21d2 closed stomata \u21d2 reduced photosynthetic capacity \u21d2 reduced light reception by lower leaves \u21d2 reduced photosynthetic capacity of lower leaves \u21d2 insufficient supply of carbohydrates to roots \u21d2 reduced root vigor \u21d2 wilting \u21d2 lower yield and quality.<\/p>\n\n\n\n

0To reduce damage caused by high temperatures, it is necessary to improve efficiency through information-based soil preparation, introduction of countermeasures that address the issues of each field, and medical record management (drone sensing is extremely useful for such information and can be evaluated visually (with high accuracy), and is a weapon in the armory of farm management guidance. It is a weapon in the armory of farm management guidance).<\/p>\n\n\n\n

\u3000The above shows that the stable early growth of rice plants by \"side-rowing + seedling box-less\" and the continuous supply of small amounts of nitrogen during the seedling maturation period, as well as the improvement of photosynthesis by the application of slag (silicic acid) and the securing of roots during rice maturation by suppressing reduction (spraying Agri Revolution \u21d2 promoting rice straw rotting), are essential for rice production (reducing quality decline and securing stable yields) that is not affected by weather fluctuations. This is essential for rice cultivation that is resilient to weather fluctuations (reducing quality decline and ensuring stable yields), and is considered to be a trump card for rice cultivation in the future.<\/p>\n\n\n\n
