Dryland direct seeding technology has significant application potential in sandy soils because the physical properties of sandy soil make it particularly suitable for dry land direct seeding. This approach not only reduces dependence on water resources, but also increases sowing efficiency and crop yields.
Sandy soil has good water permeability and drainage due to its larger particles, which allows the soil to quickly remove excess water and reduce the risk of water accumulation. During dryland direct seeding with rice seeders, this feature prevents seeds from rotting due to excess moisture, thereby improving the germination rate of seeds.
Moisture management: Sandy soil suitable for dryland direct seeding can effectively control soil moisture, maintain a moderately moist state, and promote seed germination without becoming overly wet.
good soil structure
Sandy soil has a loose structure, and the loose soil structure makes it easier for the planter to work. The planter can smoothly trench and sow seeds in sandy soil without causing soil compaction or machine blockage.
Sowing accuracy: Loose soil allows the seeder to more accurately control the planting depth and distribution of seeds during the sowing process, ensuring even sowing.
Reduce traditional irrigation needs
Due to the good drainage of sandy soil, traditional irrigation methods often require a larger amount of water to keep the soil moist. Dryland direct seeding technology can reduce reliance on traditional submerged irrigation and reduce water consumption by choosing appropriate irrigation strategies, such as shallow irrigation or intermittent irrigation.
Water-saving effect: Through moderate irrigation control, sandy soil can effectively reduce water evaporation, maintain appropriate humidity, and contribute to the healthy growth of rice.
