What is suitable for planting in sandy soil? These several have good economic returns!
Sandy soil refers to soil formed by mixing a large amount of sand with a small amount of clay, and broadly refers to soil with a very high sand content. This kind of soil is loose in texture and has good water and air permeability, but its ability to retain water and fertilizer is poor, so it needs improvement when cultivated, and it is not very suitable for the growth of certain plants. So, what is suitable for planting in sandy land? These several have good economic returns!
1. Peanut
Peanut has relatively high requirements for geological soil. When choosing where to plant peanuts, it is advisable to choose sandy loam land with relatively flat terrain and strong drainage capacity. Peanut is intolerant of continuous cropping; soil used for Chinese peanuts in the first year is not suitable for planting peanuts continuously, and when choosing soil for peanut planting, it is best to choose land that has not grown peanuts for several consecutive years. In addition, the soil organic matter must be greater than 1.0%, and the soil PH value must be between 6.5-7.5. Peanut cultivation also has certain requirements for air quality conditions, requiring the air pollution index to be less than 1. Only when these geological conditions are all met at the same time is it possible to grow high-yield peanuts.
2. Watermelon
It is cultivated in various parts of China, with very many varieties, and diverse forms of outer peel, flesh and seeds, with Xinjiang, Lanzhou in Gansu, Dezhou in Shandong, Dongtai in Jiangsu and other places being the most famous. Its original species may have come from Africa, and it is widely cultivated from the tropics to the temperate zone of the world, and was later introduced into China. It is advisable to choose sandy loam soil with deep soil layers, loose and fertile soil texture, and convenient drainage and irrigation, and to cultivate it in field plots where no cucurbit crops have been grown within 5 years on dry land and within 3 years on paddy fields.
3. Walnut tree
Walnut cultivation and use in our country have a long history. It is rich in nutrition and has effects such as improving brain function and intelligence, resisting aging, preventing constipation, and lowering blood sugar. As people's living standards continue to rise, the demand for walnuts and their various processed products is growing ever larger, thereby driving walnut prices continuously upward. Walnut trees have strong adaptability, few pests and diseases, labor-saving management, convenient fruit storage and transportation, and a long lifespan. Walnut trees like warmth and light, and have stricter requirements for moisture, especially during the new shoot growth period and fruit development period, when a sufficient water supply is even more needed. They are suitable for planting in sandy loam soil with loose structure and good water retention and air permeability.
4. Licorice
It mostly grows in arid and semi-arid sandy soil, desert edges and loess hilly areas, and it also reproduces easily in fields and river beach land in the Yellow River irrigation areas. It has strong adaptability and strong stress resistance. Licorice likes an ecological environment with sufficient sunlight, relatively low rainfall, scorching summers, severe winters, and large temperature differences between day and night, and has the characteristics of liking light, tolerating drought, tolerating heat, tolerating salinity and alkalinity, and tolerating cold. It is suitable for growing in sandy soil with deep soil layers, loose soil texture, and good drainage.
5. Pear tree
The pear tree is a fruit with extremely high yield in our country, second only to apples in planting area and output, and it is cultivated all over the world. It has strong adaptability to the environment and can adapt to various terrains such as mountains, hills, and sandy wasteland. It is not strict about soil requirements, and can also grow normally in saline-alkaline and waterlogged soil. It is most suitable for growing in sandy loam soil with a relatively low groundwater level. The pear tree's root system is extremely developed, and the regenerative capacity of the roots is relatively strong, so high yield can be obtained with only slight management.
In addition to the above five kinds suitable for planting in sandy soil, everyone can also choose suitable varieties according to local climatic conditions.
