Non-woven light-matrix sowing seedling breeding method for firs

The invention discloses a non-woven light-matrix sowing seedling breeding method for firs. The non-woven light-matrix sowing seedling breeding method for firs mainly includes steps that mixing coco coir, peat soil and water-retaining agent to prepare culture matrix, and preparing into a nutritious cup through a non-woven light-matrix forming machine; soaking in 0.1-0.5% potassium permanganate solution for 30 to 60 minutes before seeding, using clean water to clean, soaking the seeds in 40 to 50 degrees centigrade hot water, cooling naturally, changing water and soaking for 24 to 48 hours, and accelerating germination in a germination accelerating machine at 25 to 30 degrees centigrade after using clean water to clean; when the seeds expose white, seeding in the light-matrix nutritious cup, and covering a piece of film; after the lateral roots of the seedlings pass through the cup, fertilizing according to the time interval of 10 to 20 days, when the seedlings are 5 to 10 centimeters high, grading to a seedling tractor, exercising seedlings at the end of November, wherein the seedlings can be sold after the exercising. The non-woven light-matrix sowing seedling breeding method for firs has advantages that roots of the fir seedlings cultured on the light-matrix nutritious cup are flourishing, the nursery plants are strong, the matrix is light so that the transportation cost and forest planting cost can be lowered, and the matrix which cannot enable the plant to survive can be recycled; a constant-temperature germination accelerating box is high in germination accelerating rate and good in germination consistency and effectively improves the germination rate of fir seeds.
