Abstract:

Facility agriculture is an effective way to efficiently utilize saline-alkali land. This paper conducts an in-depth analysis of the conditions and current situation of developing facility agriculture in the coastal heavy saline-alkali land around Bohai Sea, which clarifies three favorable factors ("not competing with grain for land and water", "safe production environment and good light and heat conditions", and "collaborative development assistance and mature technical models") and three disadvantageous factors ("small research and development platform", "weak demonstration and promotion effect", and "limited policy and financial support"). The main modes of developing facility agriculture in heavy saline-alkali land around Bohai Sea are summarized as follows: the production mode of fruits and vegetables in heavy saline-alkali area, the matrix cultivation mode of saline soil, the safe utilization mode of salt water in facility vegetables in fresh water-deficient saline-alkali area, and the high-quality production and cultivation mode of water and salt regulation of fruits and vegetables in saline soil. It proposes suggestions such as strengthening scientific and technological support, strengthening dry-alkali agriculture, and enhancing policy support, with the aim of providing references for the high-quality development of facility agriculture in the saline-alkali areas around Bohai Sea.
