Moringa oleifera (Latin name: Moringa oleifera Lamarck, English name: horseradish), also known as drumstick tree and wasabi tree, belongs to Moringa family, ranging from small evergreen trees to large trees. There are 14 species of Moringa oleifera, and two species of Moringa oleifera are cultivated for food. Moringa oleifera is native to places with extremely harsh natural conditions, such as the foothills of the sub-Himalayas in northeastern Africa and northern India and the coast of the Red Sea.
Moringa oleifera is a new health plant (food) in Europe and America since 20 12. It is said that high calcium, high protein, high fiber and low fat have the functions of strengthening physical strength, treating anemia, inhibiting bacteria and expelling insects.
Moringa seed: Moringa seed looks strange. Its pod looks like cowpea, but its seed is not regular at all. It has horns and different sizes, and can be eaten raw. It is said that Moringa seed has obvious health care and prevention effects on diabetes and hypertension. It is crisp and sweet in the mouth. Chew slowly, swallow it and drink water. The sweetness in the throat is similar to that of licorice, but better than licorice. And can be kept for several minutes. In the meantime, you will feel very sweet when you eat other foods. Moringa seeds also have the effect of sobering up and removing bad breath. Generally, eat 3~5 Moringa seeds about half an hour before drinking, and then eat 3~5 seeds after drinking, which has a good hangover effect. Chewing Moringa seeds can also effectively eliminate bad breath and the smell of smoke in smokers' mouths.
Land improvement is a process of taking corresponding physical, biological or chemical measures to improve soil properties, improve soil fertility, increase crop yield and improve the soil environment for human survival.
The process of soil improvement is divided into two stages:
1. In the stage of soil and water conservation, take engineering or biological measures to control soil erosion within the allowable range. If soil erosion is not controlled, soil improvement cannot be carried out. In order to cultivate land, we must first carry out farmland capital construction.
2. Soil improvement stage. Its purpose is to increase soil organic matter and nutrient content, improve soil properties and improve soil fertility. The main measures to improve soil are planting leguminous green manure or applying more farmyard manure. When the soil is too sandy or sticky, the sand-sticky mixing method can be used. The eroded soil in the acidic red-yellow soil area in southern China is short of phosphorus, so phosphorus fertilizer must be applied to improve the soil when planting green manure crops.
The measure of changing soil pH with chemical improver is called soil chemical improvement. Commonly used chemical modifiers are lime, gypsum, phosphogypsum, calcium chloride, ferrous sulfate, calcium humate and so on. , depending on the nature of the soil. For example, gypsum and phosphogypsum should be applied to alkaline soil to exchange calcium ions and sodium ions on the surface of soil colloid and reduce the PH value of soil. For acidic soil, calcareous substances need to be applied. Chemical improvement must be combined with water conservancy, agriculture and other measures to achieve better results.
The process of taking corresponding agricultural, water conservancy and biological measures to improve soil properties and fertility is called soil physical improvement. The specific measures are: timely farming, increasing application of organic fertilizer and improving poor soil; Exotic soil, overflow sand, overflow sludge, etc. , improve sandy and cohesive soil; Leveling land; Set up drainage and irrigation system, drain water and wash salt, plant rice and wash salt. , improve saline-alkali land; Planting trees and grass, building shelter forests, setting sand barriers, fixing quicksand and improving aeolian sand.
Moringa trees can improve the land. Because Moringa oleifera soil is rich in organic matter and nutrients, it can improve soil properties, improve soil fertility and increase crop yield. This is very helpful for the growth of plants. It is also beneficial to improve soil fertility and promote plant growth. So Moringa trees can improve the land.
