Urban landscape greening produces a lot of defoaming every day. Exfoliation is a good organic fertilizer material with low price. The nutrient content in the leaves is quite high. Application of fallen leaves as organic fertilizer can improve soil, increase soil organic matter content, improve soil additive conditions, improve soil fertilizer and water-saving capacity, and regulate soil pH.
According to the determination, apple leaves contain 3% – 6%, 0.2% – 0.3% phosphorus, 2% potassium and many trace elements; pear leaves contain 2% – 2.2% nitrogen, 0.1% – 0.25% phosphorus and 1.2% – 2.6% potassium. After the whole fruit stage, the nitrogen content in the leaves of the whole tribe in each mu pear orchard was equivalent to 98 kg ammonium bicarbonate, 12 kg super phosphate and 20 kg potassium carbonate. These organic fertilizers are rich in organic matter and can be used to grow flowers, grass and vegetables. Stacking fallen leaves on tree roots can also improve soil poverty. If all the tribal leaves of the tree are used as organic fertilizer, then the tree does not need additional fertilizer.
Exfoliating organic fertilizer
The nutrients in the leaves are easily converted into organic fertilizer by composting, which is harmless to plant growth and alkalinity. There were significant differences in nutrient content and C / N ratio among different plants. According to the actual content of raw materials, adding appropriate amount of high nitrogen material, adjusting C / N ratio and microbial agent, accelerated the composting process. The recycling of exfoliated organic fertilizer reduces the amount of chemical fertilizer applied, improves the quality of green soil, and realizes the recycling of garden material metabolism.
