Embodiment 1
[0058] ——The experimental location is Yanhe Town, Yuxi City, Yunnan Province. The experimental variety is Yunyan 87
[0059] A. Floating seedling cultivation: The sowing date of tobacco seedlings is February 22. After the tobacco seedlings are sown into the matrix planting holes, place the seedling raising floating tray on the surface of the nutrient bed pool, and cut the leaves when the tobacco seedlings are 6 cm high, twice before and after. Cut off water and control fertilizer before transplanting, harden the seedlings for 8 days, let the tobacco seedlings absorb enough water and fertilizer, and prepare for transplanting after 2 days.
[0060] B. Land preparation and ridging: shallow plowing and stubble removal in time after the previous crops are harvested, 25 days before transplanting the crushed soil to store entropy, deep plowing and land preparation, and watering the field 10 days before transplanting. According to the row spacing of 100cm, the ridge height is 20cm, th...
