Embodiment 1
[0065] A kind of nutrient application method of red cone seedling stage, comprises the following steps:
[0066] (1) Determination of NPK content of nutrients in seedlings when red cones are transplanted: select seedlings of red cones with consistent growth, wash 50 plants with a seedling height of 8cm-10cm, dry, grind, and sieve for total N, P, and K content. Measured to obtain the initial content of N, P and K of the red cone seedlings;
[0067] (2) Determination of NPK content of red cone seedlings when they emerge from the nursery: select red cone seedlings with an average seedling height of 32 cm and a ground diameter of 5 mm, take 50 seedlings, rinse them with tap water, rinse them with distilled water three times, and place the materials in 105 ℃ blast dryer for 30 minutes, and then fully dry at 70-80 ℃, every 10 plants as a group, measure the total dry weight respectively, then measure the NPK content of each group of seedlings, and calculate the NPK required for each ...
