The fertilizer made from green plant body can be collectively called green manure. The young stems and leaves of plants are rich in nutrients. Once decomposed in the soil, they can evolve into green manure. There are many types of them, and in fact, they can be clearly divided into summer green manure and winter green manure according to the season. The most common one is winter green fertilizer, a traditional source of organic fertilizer in the south.
1. What are the benefits of planting green manure?
① Low investment and high fertilizer efficiency: When planting green manure, only a small amount of seeds and fertilizer are needed, plant on-site, harvested and used on-site, saving manpower and transportation capacity than other organic fertilizers. At the same time, green manure is rich in organic matter and contains nitrogen, phosphorus, potassium and a variety of trace elements, which decompose quickly and have rapid fertilizer effect.
② Improve the soil and prevent soil erosion: Because green manure contains a large amount of organic matter and has a developed root system, especially legume forage has a large number of rhizobia, which can improve the soil structure and improve the soil's ability to retain soil and water.
③Great utilization benefits: Green manure can not only increase soil fertility, but most forage grass can be used as feed to feed livestock, also known as fertilizer and green manure. While developing animal husbandry, livestock manure can fertilize the fields, and the two can promote each other.
号用正 green manure is familiar with. In winter, green manure is cultivated in all parts of my country. Hairy vegetarian is not only an important green manure crop in paddy fields and cotton fields, but also a good feed for livestock and poultry.
2. Key points of planting hairy vulgaris:
1. Sowing time: Hairy vulgaris is usually sown from the end of July to mid-to-early September.
2. Sowing volume: The sowing volume should be determined according to different regions, soil conditions and sowing time, generally 3kg/mu. You can spread a little more on slopes, barren and thin areas, and late-sowed areas.
3. Planting method: Hairy vulgaris can be divided into various planting forms such as intercropping, single cropping, intercropping, mixed or multi-seeding.
4. Sowing method: When sowing the hairy sweets, you can be sown on demand, sprinkled or spread.
5. Fertilization: Apply base fertilizer before sowing, generally apply about 15-20 kg of superphosphate and wood ash each. Mix them together for base fertilizer application. If the growth is thin during the seedling period, you can apply urea 4-5 kg and pig manure to splash it to promote growth.
6. Field management: Hairy sweets are not resistant to waterlogging. The focus of field management is water management, and wet ditches should be paid attention to drainage and irrigation.
7. Harvest or roll pressure in time: Growing hairy sweets can be harvested 1-2 times before winter. The harvested fresh grass can be applied to other fields or plated under fruit trees. When cutting green, the stem should be left 10-15cm, and manure water should be applied in time to promote regeneration.
High-fruit vulgaris is timely turned and pressed, and the plants are tender and tender too early, with low yield, and decompose quickly after greening, and have shorter fertilizer effect. The turn pressure is too late, the plant is aging, the nutrient content of stems and leaves is low, and it is not easy to decompose in the soil, reducing fertilizer efficiency. When turning green manure, consider the matching of the fertilizer rules for the subsequent crops.
Generally, the appropriate time for furry sweets to turn from the flowering period to the flowering period. If it is a drought-free orchard, you can sprinkle crushed soil about 5 cm thick on the grass layer, which will make the effect better.
-haired vulgar seeds:
-haired vulgar is used as forage, with high yield and good palatability. It is a high-quality green feed for pigs, cattle and chicken:
-haired vulgar is used as forage, and the yield per mu of fresh grass can be as high as 2500-3500 kg. It can be mowed and fed directly, or piled up and stored or made into grass powder. It can be used as silage if the area is large. Because of its many leaves and few stems, it has high protein and mineral content, low cellulose content, soft and tender grass, and good palatability, it is a food that all kinds of domestic animals, especially pigs, cattle and chickens.
