Many people don’t believe that green manure can improve the soil. Isn’t it just grass? Is it such a big purpose? Why are there no one developing a lot of abandoned saline-alkali land? And so on, with this question, we can understand it, because many people still don’t know much about green manure. Today, I will take you to learn about green manure.
Green manure is also called green "gold", which can improve the soil and serve as a natural fertilizer to achieve high yields in agriculture. Why can green manure improve the soil?
First of all, green manure has strong vitality and can settle down in places where ordinary crops are difficult to live and reproduce in large quantities. Many people often ask them to be pioneers and go to the very difficult drought, flood, salt, alkali, acid, barren saline-alkali wasteland or red soil wasteland to "settle". They not only take root there with peace of mind, but also actively create a beautiful living environment for crops.
When the soil salt content exceeds 0.2%, general crops cannot live normally, while the green fat family of field cyanine , hairy sweet potato , alfalfa, purple sophora , etc. can grow well and gradually help the soil desalination. According to experiments, after planting hairy sweets in saline-alkali land for three years, the soil salt content dropped to 0.03%. In this way, many crops can grow smoothly. It is calculated that if 1500 kg of vinegar per mu, the soil will be equivalent to adding 57 kg of nitrogen fertilizer , 12 kg of phosphorus fertilizer , and 13 kg of potassium fertilizer .
Green manure-What are the characteristics of hairy sweets? What are the advantages?
Horse sweets are more acid-resistant, salt-alkali-resistant, cold-resistant and drought-resistant. They can also rely on the secretions of the root to "digest" some nutrients that are difficult to absorb and utilize by crops; after they die and rot, the soil surface will leave rich nutrients.
hairy sweet potatoes can not only improve saline-alkali land, but also plant them in orchards, which can inhibit the growth of weeds, such as planting them in apple orchards, vineyards, kiwis, orange orchards, etc., fields, orchards, slopes, etc., and they can grow well anywhere and have very strong adaptability.
High Grass per mu of land can produce up to 2000-3300 kg of fresh grass per mu. Because of the many leaves and few stems, the grass is very soft and tender, the protein and mineral content is relatively high, the cellulose content is low, and the animals raised have a good taste. Therefore, it is a green forage that is particularly popular among all kinds of livestock, especially pigs, cows, sheep and chickens. It can be mowed and fed directly. In areas with better conditions, fresh grass can be harvested, silated or dried, and made into grass powder for storage. It is used as the main raw material for mixing or mixing materials. It is very convenient to feed it as you pick it up and feed it as you want.
