Green manure refers to the green plant body that is applied directly after burying or stacking. Different types can be divided from different perspectives. According to the growing season, it is divided into winter green manure, summer green manure, spring green manure and autumn green manure. Winter green manure: mostly for autumn or early winter sowing. In the spring or summer of the next year, it can be used in winter for more than one year, such as Chinese milk vetch and medlar. Among them, the content of fresh grass of Ziyunying (% of green body) nitrogen (N): 0.33, phosphorus (P2O5): 0.08, potassium (K2O) 0.23; hay composition (% of dry weight) nitrogen (N): 2.75, Phosphorus (P2O5): 0.66, potassium (K2O) 1.91; common hazelnut fresh grass components (% of green body) nitrogen (N): 0.56, phosphorus (P2O5): 0.13, potassium (K2O) 0.43; hay composition ( % of dry weight) Nitrogen (N): 3.11, P (P2O5): 0.72, Potassium (K2O) 2.38; Summer green manure is mostly planted in spring or summer, used in early autumn, more than half of the growth period in summer, such as Tian Jing , mung beans, etc. Among them, Tianjing fresh grass components (% of green body) nitrogen (N): 0.52, phosphorus (P2O5): 0.07, potassium (K2O) 0.15; hay composition (% of dry weight) nitrogen (N): 2.60, phosphorus (P2O5): 0.54, potassium (K2O) 1.68; among them, mung bean fresh grass component (% of green body) nitrogen (N): 0.60, phosphorus (P2O5): 0.12, potassium (K2O) 0.58; hay composition (dry weight) %) Nitrogen (N): 4.17, phosphorus (P2O5): 0.83, potassium (K2O) 4.03; spring green manure is planted in early spring, used before midsummer, more than half of the growth period in the spring. In autumn, green manure is sown in summer and early spring. It is used for turning over before winter, and the growth period is mainly in autumn, such as ramie in autumn. Among them, ramie fresh grass components (% of green body) nitrogen (N): 0.78, phosphorus (P2O5): 0.15, potassium (K2O) 0.30; hay composition (% of dry weight) nitrogen (N): 2.98, phosphorus (P2O5): 0.50, potassium (K2O) 1.10.
Main utilization methods: 1. Direct tillage Direct tillage and green manure are the main ways to use green manure. They provide nitrogen and other nutrients for seasonal crops or crops, and provide a large amount of fresh organic matter directly to the soil. 2. Heap and alfalfa fertilizers will be used to pile up green manure with straw, ring fertilizer, weed mud and other wastes. 3. The nutritional value of feed green manure is very high. The crude protein content of legume green manure is 15%-20%, and contains various amino acids and various vitamins. Planting fertilizer and green manure crops are important directions for the development of green manure production.
