The invention relates to the technical field of forest cultivation, and specifically discloses a seedling raising method for Simao pine, comprising the following steps: soaking Simao pine seeds in a potassium permanganate solution; after sprinkling water, a substrate is put into a seedling raising container, and the substrate includes chaff and Perlite; pre-treated seeds are sown in a seedling container, and 1-4 pre-treated seeds are sown in the seedling container, and the depth is 1-2 cm; nutrient solution and fertilizer are sprayed 2-3 weeks after pre-treatment seeds are sown on-demand, The frequency of spraying nutrient solution and fertilizer is once a week, the nutrient solution is water and the nutrient solution contains MgSO 4 , K 2 SO 4 , Ca(H 2 PO 4 ) 2 and CaSO 4 , and the addition amount of the nutrient solution is 9‑ 15mL; the fertilizer is urea, and the initial application amount of the fertilizer is 0.8-1.25mg, and the fertilizer application amount thereafter is 1.5-2.0 times the previous application amount, which has the advantages of a short seedling-raising period of Simao pine and easy popularization. |
