A kind of fertilization method of soapwort in coastal saline-alkali land

Abstract

The invention relates to a fertilizing method for saponaria officinalis in coastal saline-alkali soil. The method comprises the following steps: digging dressing furrows, and filling and leveling the dressing furrows up after applying fertilizers before the flowering stage every year in the areas where the saponaria officinalis is planted for three years or more. The fertilizing method for the saponaria officinalis of the coastal saline-alkali soil solves the problem that the saponaria officinalis is hard to fertilize, the operation is simple, the landscape effect can be basically recovered two to five days after fertilization, and the soil surface can be covered by vegetation within thirty days.

Description

technical field [0001] The invention relates to a method for fertilizing vegetation in coastal saline-alkali land, in particular to a method for fertilizing saline-alkali conservation in coastal saline-alkali land. Background technique [0002] The salt content of the soil in coastal saline-alkali areas can generally reach 0.5-1.0%, the pH value> 8.0, and the nutrients are poor. At the same time, the groundwater level is high, the salinity is high, and the natural drainage is not smooth. Generally landscaping plants are used for landscaping, which have poor stress resistance, require careful maintenance and management, are expensive and are easy to degrade. [0003] Soapwort (Saponaria officinalis), also known as stone alkali flower, is a perennial herb of Caryophyllaceae Saponaria officinalis, with thin rhizomes, many branches, erect stems, unbranched or upper branches. Soapwort is strong in nature, resistant to extensive management, and has no strict requirements on s...

Problems solved by technology

However, when planting soapwort in a large area, the plant density is too large after three years of growth, completely covering the ground surface, and it is difficult to fertilize. The liquid fertilizer sprayed on the leaves cannot meet the growth needs, and it is prone to inconsistent heights, smaller flowers, etc., and the appearance of the product will decline. , affect viewing, so it is not suitable for long-term large-scale promotion and application
