Abstract
The invention discloses a method for inhibiting collards from bolting and prolonging the viewing period of collards. The method comprises the steps of seedling cultivation, rational fertilization, field planting, plant hormone spraying and field management. By spraying a cycocel solution, stems of the collards become thick and strong, the leaf color of the collards become deeper, cell walls become thicker, metabolism becomes slow, and therefore the cold resistance of the collards is improved. By postponing seeding time and spraying a maleic hydrazide solution, the plants are effectively inhibited from bolting and flowering, the viewing period is prolonged by 30 days or more, and therefore the garden effect of the collards is greatly improved. Based on the method, bolting and flowering of various collards are effectively inhibited and postponed, the viewing time is prolonged, and economic benefits are increased; besides, the method is simple, feasible and convenient to operate.
