The soil in these fruit tree areas is relatively poor, with low organic matter content and poor physical and chemical properties of the soil. It cannot well maintain fertilizer and water, thus bringing certain difficulties to the growth and investment management of fruit trees.

Text/Lative Life and Gardening

The planting area of ​​fruit trees in my country is relatively large and distributed relatively widely. Most of them are mainly distributed in hilly and mountainous areas and saline-alkali beaches, and are relatively barren soil areas. The soil in these fruit tree areas is relatively poor, with low organic matter content and poor physical and chemical properties of the soil. It cannot well maintain fertilizer and water, thus bringing certain difficulties to the growth and investment management of fruit trees. Therefore, being able to solve the growth of fruit trees and the product quality of fruits in this environment has become the first issue that these planting areas need to consider.

orchard planting green manure crop can not only fertilizer and improve the soil, but also economically utilize the land; if green manure crops are planted on sandy and slopes, it also has the effect of preventing wind and sand and maintaining water and soil, it will greatly reduce soil runoff and erosion; in addition, green manure crops cover the ground, which can also reduce evaporation, prevent salt reflux, inhibit weeds, regulate soil temperature, and be conducive to root activity.

The role of green manure

There are many types of green manure crops. We should choose the most suitable green manure crop planting based on the terrain, fruit tree type, soil quality, etc. of the orchard; we should also use the green manure crops to press green or ferment to decide which green manure crops are planted. But no matter which green manure crop, its effects are basically the same.

1 and can increase the organic matter content of in the soil and improve the physical and chemical properties of the soil. Green manure crops have strong root systems and account for a large proportion of plants. Their upper ground often grows vigorously, forming a large number of green bodies and rich organic matter. Their fresh stems and leaves generally contain more than 10-15% organic matter. If they can return to the soil normally, it will improve the organic matter of the soil and improve its physical and chemical properties. When

organic matter decomposes, it can generate a special acid, which can promote the respiration of the root system of the fruit tree and improve the permeability of the cell membrane, thereby enhancing the absorption capacity of the mineral element , and promoting cell division and accelerating the growth of the root system and the above ground. When green manure is turned into the soil, in addition to providing nitrogen, it can also stimulate and decompose the organic matter of soil, promote the circulation of substances, maintain good soil traits, and ultimately make fruit trees high and stable yields.

2, increases the soil and can give state nutrients. Green manure crops generally contain nitrogen, phosphorus, potassium and a variety of nutrients. Studies have shown that planting or turning green manure or turning green manure can increase the amount of affordable nutrients in the soil. Because the organic acid secreted by the roots of green manure crops can turn insoluble nutrients in the soil into affordable states, thereby improving the utilization rate of nutrients by fruit trees.

Green manure can continuously release affordable nutrients during the process of fermenting and rotting, and can be absorbed and utilized by fruit trees.

3, promotes the growth and development of fruit trees. From the above, it can be seen that green manure has the functions of improving the giveable nutrients in the soil, improving the physical and chemical properties of the soil, coordinating water, fertilizer, gas, etc. in the soil, and promoting root activity. Therefore, its role in the growth and development of fruit trees also plays a role in promoting the growth and development of fruit trees. After the orchard was applied to green manure, the volume of the crown increased significantly, the new shoots grew well, the flower buds were many, the fruit set rate increased, the single fruit weight and yield were improved, and the fruit storage tolerance was also improved.

Green manure selection

Green manure has a very rich resource, a wide variety, and can also be planted using wild resources. Among them, the most commonly used types are: broad beans, peas, cymbidium, etc.

Purple Sophora : This green manure crop is highly adaptable and can grow in all types of soil, and it grows relatively vigorously. It can be harvested multiple times a year, and is suitable for planting orchards in sandy wastelands, saline-alkali lands, and hilly and mountainous areas.

用球方 (xi): is relatively resistant to barrenness and has no requirements for the pH of the soil. It can be planted on sandy land or terrain with a high sandy content, which can absorb nutrients and water in the deep soil, but this green manure is not resistant to waterlogging. Therefore, when we plant, we should not plant in low-lying water-stabilized areas.

Polymerized grass: This green manure crop is very adaptable and can withstand cold and heat. It grows relatively quickly and produces a large amount of fresh grass. It can be cut 2-4 times a year. It is very suitable to plant this green manure in cold areas.

Planting green manure crops in orchards is also a way to improve the soil in the garden. However, the selection and application of green manure is a relatively strict matter. I hope I can share with you next time: the planting and specific utilization methods of green manure crops.
