Matrix soil for salvia splendens cultivation and use method thereof

Abstract

The invention discloses a matrix soil for salvia splendens cultivation and a use method thereof. The matrix soil is obtained by compounding of ordinary soil, a sludge composting product and peat soil. The matrix soil has good nutrient supply capability, has high content of organic matters, nitrogen, phosphorus, potassium and nutrients, and can provide a good nutritional status for salvia splendens growth. Adding of the composting product can improve the buffering ability of the matrix soil to acid and alkali and improve the cation exchange capacity therein, thus improving the fertilizer retaining capacity of the matrix soil. At the same time, the matrix soil has good physical properties, good soil porosity and capillary porosity, and improves ventilation and water permeability as well as water holding capacity of the matrix soil. The matrix soil combines water retention, fertilizer retention, air permeability and other characteristics, and can meet the physical structural requirements of salvia splendens for matrix soil. While used for cultivation, the matrix soil provided by the invention also can effectively consume municipal sewage sludge and achieve resource utilization, promotes the pollution control and recycling of resources, thus having very high value of environmental protection.

Description

technical field [0001] The invention belongs to the technical field of flower matrix fertilizer and the field of sludge resource utilization, and relates to a matrix soil used for the cultivation of a bunch of reds and a use method thereof. Background technique [0002] A bunch of red, also known as firecracker red, ivory red, western carmine, wall red, ivory crabapple, paozai flower, and sycamore, is a plant of the genus Salvia in the labiatae family. A bunch of red inflorescences are slender, bright red, long flowering period, and strong adaptability. A bunch of red potted plants are suitable for arranging large flower beds and flower borders. The landscape effect is particularly good, so it is the most commonly cultivated herbal flower in cities and gardens in my country. [0003] A string of reds likes the sun and is also resistant to half shade. It requires loose, fertile and well-drained sandy loam. A string of reds can grow new shoots and bloom multiple times in a yea...

Problems solved by technology

At present, due to the extremely low fertilizer efficiency of ordinary cultivation soil, the fertilizers used by Yichuanhong are mainly quick-acting chemical fertilizers, which dissolve quickly after being applied to the soil and have short fertilizer effects. If too much chemical fertilizer is applied at one time, it will cause Yichuanhong to occur The phenomenon of "burning roots" makes the application of chemical fertilizers follow the principle of a small amount and multiple times, which greatly increases the labor workload of the growers

At the same time, after the application of chemical fertilizers to ordinary cultivation soil, it is easy to cause soil compaction, which reduces water permeability and air permeability, and affects the growth and quality of plants to a certain extent.
