Because green manure can be activated; absorb potassium, etc., legume green manure can also fix nitrogen, which can improve the growth of plants. At the same time, it can also avoid the problem of poor matching of elements between fertilizers, reduce the investment in petrochemical products, and provide a large amount of nutrients for the growth of crops to avoid antibiotics; hormone residues, let’s take a look at which plants are commonly used for green manure!
1: Ziyunying
Recommended reason:
Ziyunying is an important green fertilizer crop with strong nitrogen fixation ability and high utilization efficiency. Therefore, it can stimulate a large amount of soil nitrogen when the plant decomposes, which plays an important role in maintaining nitrogen circulation in the farmland ecosystem.
Ziyunying is also a kind of livestock feed, which is palatable, and all kinds of livestock like to eat, and is rich in nutrition. As high-quality feed and protein supply feed, Ziyunying has excellent results. In addition, Ziyunying can also use both green manure and forage, with a very high availability rate, so the animal husbandry value is very high.
2: Vagina
Recommended reason:
Vagina's cold resistance is stronger than that of Ziyunying and Arrow Pea. The wintering rate of Vagina seedlings in the middle and lower reaches of the Yangtze River is very high. Vinegars are drought-resistant and stain-resistant.
Vagina has been cultivated and utilized as green manure in orchards in north and south my country for a long history and is one of the important green manure crops in orchards. At present, there are three types that are more cultivated in orchards, namely hairy, light-leafed and ordinary. Hairy-leafed Varieties are mainly distributed in northern my country, while Guanglei Varieties are mainly distributed in the Huanghuai River and the Yangtze River Basin. Jiangtong Varieties are a local species, mainly distributed in Sichuan, Hubei, Jiangsu, Jiangxi and other provinces.
3: Purple Sophora
Recommended Reasons
(1) Strong vitality
Purple Sophora 118 likes dry and cold climates, and grows best in North China with an average annual temperature of 10℃ to 16℃ and an annual precipitation of 500 to 700 ml. It has strong cold resistance and strong drought resistance, and can grow in areas with a precipitation of about 200 ml. It also has a certain ability to withstand flooding, and will not die even if it is immersed in water for one month. Adequate light requirements. Not strict requirements on soil.
(2) High nutritional value
Purple-sized locust is a good feed plant. It has large leaves and is rich in nutrients. The branches and leaves can be directly used or adjusted to make grass powder. Every 500 kg of air-dried leaves of Purple Sophora contain 12.8 kg of protein, 15.5 kg of crude fat, 5 kg of crude fiber, and 209 kg of soluble nitrogen-free leaching. The crude protein content is 125% of alfalfa. The content of essential amino acid in the dried leaves is lysine 1.68%, methionine 0.09%, threonine 1.03%, iso leucine 1.11%, histidine 0.55%, leucine 1.25%
