What crops are suitable for sandy soil
Main text core guide: What crops are suitable for sandy soil and a review of four types of crops and flowers suitable for planting in sandy soil, which will be introduced by the editor.
Different soil structures have different effects on crop growth and yield formation. Sandy soil is loose in structure, has good ventilation and water permeability, and has large temperature differences between day and night, making it suitable for cultivating crops on sandy soil. This mainly includes crops cultivated for the purpose of harvesting underground organs and crops originated from desert areas, including the following four types:
1. Root Vegetables
Root vegetables include radishes, carrots, burdock, rooted celery, horseradish, etc. The edible commercial organs of this type of vegetable are the swollen flesh roots. In the process of forming the product organs, the relatively loose sandy soil is conducive to the expansion of the roots and is more uniform and beautiful in appearance, making harvest easier and the selling price higher.
In heavier and粘粘的 soils, due to the strong soil cohesion, the suitable soil moisture range for these root vegetables to expand is small. When the humidity is high, poor ventilation is not conducive to root growth, and even causes rot. When the soil moisture content is low, it is too compact, and the pressure on the root volume increases, which not only不利于 yield formation but also easily forms malformed roots with low commercial value.
2. Tuberous Crops
3. Peanuts
Peanuts prefer dry and loose sandy soil. The formation of peanut fruits occurs after the above-ground part flowers, and the pistil penetrates into the ground for expansion and development. Sandy soil is conducive to the pistil's penetration into the ground and expansion. In heavy soil, due to the high soil compaction and relatively poor soil ventilation, the fruiting rate of the pistil decreases, thereby affecting yield.
The root growth of peanuts requires high soil permeability. In heavy soil, it is prone to root rot and disease due to waterlogging, causing significant losses in growth and yield formation. Heavy soil also causes peanuts to be affected by compression, thus affecting yield formation and increasing the proportion of malformed fruits, reducing commercial value. In sandy soil, it is more conducive to peanut harvest, reducing the fruit drop rate in the soil, and reducing losses.

4. Watermelons
Watermelons prefer sandy soil, and watermelons grown in sandy soil have higher quality. This characteristic of watermelons is related to their place of origin. The original population of watermelons grows in the desert areas of Africa and has developed a strong adaptability to sandy soil over long-term evolution.
In terms of their growth and development characteristics, the roots of watermelons have a strong metabolic capacity during growth, and these physiological activities require a large amount of oxygen supply as a basis. The clayey soil is relatively dense, making it difficult to meet the high demand for oxygen.
Watermelons are prone to infectious diseases during growth, and the occurrence of these diseases is mostly related to high soil moisture. Sandy soil has relatively low humidity and is easier to maintain a dry soil state, effectively reducing the incidence of watermelon diseases. In addition, watermelons cultivated in sandy soil have a more prominent sweetness and flavor, mainly because the temperature difference between day and night in sandy soil is greater. The organic matter produced by photosynthesis in watermelons during the day is less wasted due to the lower temperature at night, and less respiratory consumption by the plant, thus more nutrients accumulate in the watermelon fruit, increasing its sugar content.
The lower water-holding capacity of sandy soil can easily cause a deficiency in root water supply, creating an adverse growth environment for watermelons. This process is conducive to the production of secondary metabolites in the growth of watermelons, which are important substances for improving the flavor of watermelons.
