Preparation method and application of compound fertilizer of pine needle leaf extract

The compound fertilizer is prepared from the following raw materials: pine needles, starch, sodium periodate, epsilon-polylysine, lanthanum cerium carbonate, a first fermentation strain, a second fermentation strain, gamma-polyglutamic acid, potassium citrate and magnesium nitrate. The mass ratio of the pine needles to the starch to the sodium periodate to the epsilon-polylysine to the lanthanum cerium carbonate to the first fermentation strain to the second fermentation strain to the gamma-polyglutamic acid to the potassium citrate to the magnesium nitrate is (50-100): (5-10): (0.1-0.5): (1-2): (0.01-0.1): (1-2): (0.1-1): (1-5): (2-4): (1-5). The invention discloses a preparation method of the compound fertilizer of the pine needle leaf extract. The invention discloses application of the compound fertilizer of the pine needle leaf extract in rice planting. The method can improve the additional value of pine needles, and has the characteristics of rich resources, safety and remarkable effect. 本发明公开了一种松针叶提取物的复
