Category	Non-salinization	Mild salinization	Severe salinization	Saline soil
Characteristic	Satisfactory crop vegetation growth; no seedling phenomenon or light spots	Slightly inhibited crop growth; approximately 1/5–1/2 loss of seedlings	Severely inhibited crop growth; more than 1/2 missing seedlings; more light spots	Negligible crop growth; numerous light spots
