まだ「30日目」に水を抜いてるの？中干しの新常識と失敗しない判断基準

"Mid-season drainage should be done one month after planting" is wrong! This video explains the correct timing based on tillering and how to avoid over-drying and regretting it in the fall.

The "Just Right Drying Method" Varies Completely Depending on Soil Type 07:19 Over-Drying Kills Roots! Secrets to Preventing Autumn Drop 09:03 Summary ▼ What You Can Learn from This Video ✅ The Timing of Mid-Season Draining Should Be Judged by "Stem Count," Not "Days" For standard density (18-21cm spacing between plants, 30cm spacing between rows), aim for 15-20 stems per plant, or 70-80% of the target number of panicles. For sparse planting, judge by the total number of stems per tsubo (approx. 3.3 sq m). ✅ The Mechanism by which Draining Water Stops Tillering The nitrogen that microorganisms continuously release while submerged in water is restricted, putting a sudden brake on tillering. Because this process is so rapid, it's crucial to check the current stem count before starting. ✅ How to Determine When the Rice is Dry The goal is for the rice paddies to be dry enough to leave small cracks and light footprints. This varies greatly depending on the soil type: around 10 days for clayey soil and within 5 days for sandy soil. ✅ Over-drying will have repercussions until autumn Large cracks can break the roots and reduce the soil's water retention. This can cause "autumn decline" during the ripening stage, lowering both quality and yield. Mid-season drying is a crucial management task that affects not only the "present" but also autumn yield, quality, and combine harvester workability. ▼ Editor's Notes While making this video, I realized again that mid-season drying isn't simply "draining the water." The extra step of counting the number of stems greatly impacts the autumn yield. Honestly, I was researching thinking how nice it would be if the rice grew well just by following the calendar (lol), but rice paddies aren't that simple. Looking at the rice paddies, looking at the stems, and then making a judgment—I believe this simple habit will change the autumn for farmers. ━━━━━━━━━━━━━━━━━━━━ 🌾 Subscribe to our channel here    / @tano41com   We deliver useful information from the rice farming field every week.
