Cultivation medium for spring sword

Abstract

The invention discloses a cultivation medium for a spring sword, comprising nutrient soil 2, deadwood soil, fern root soil and active soil, and volume ratio of nutrient soil 2 to deadwood soil to fern root soil to active soil is 4: 3: 2: 1 or 3: 4: 2: 1, wherein the nutrient soil 2 is obtained by mixing mud pool soil, leaf mould, rapeseed and saprolite in the volume ratio of 1: 1: 1: 1. Cultivation medium 6 (the volume ratio of nutrient soil 2 to deadwood soil to fern root soil to active soil is 4: 3: 2: 1) and cultivation medium 7 (the volume ratio of nutrient soil 2 to the deadwood soil to fern root soil to active soil is 3: 4: 2: 1) contain high proportion of leaf mould, rapeseed and saprolite components, thus the whole nutrient preserving capability of the cultivation medium is greatly improved, nutrition absorbed by a root system from the cultivation medium, especially N element, can better meet vegetative growth requirement of the spring sword. The cultivation medium 6 (the volume ratio of nutrient soil 2 to deadwood soil to fern root soil to active soil is 4: 3: 2: 1) and the cultivation medium 7 (the volume ratio of nutrient soil 2 to the deadwood soil to fern root soil to active soil is 3: 4: 2: 1) has better air permeability and water permeability and can better meet requirement of the spring sword to nutrient elements such as N, P, K and the like.

Description

technical field [0001] The invention relates to a spring sword cultivation substrate. Background technique [0002] The cultivation substrate is a growth medium that provides plants with a stable and coordinated structure of water, air and fertilizer. In addition to supporting and stabilizing the plants, more importantly, it acts as a "transfer station" to transfer water and nutrients, and the roots of the plants can selectively absorb them as needed. Therefore, the study of substrate is the first step of soilless cultivation, and it also reflects the level of success of soilless cultivation. [0003] Cultivation substrates are divided into solid substrates and non-solid substrates. Non-solid substrate soilless cultivation means that the root system grows directly in the nutrient solution or moist air containing nutrients, and there is no solid substrate in the rhizosphere environment. It is divided into two types: hydroponics and aeroponics. Hydroponics refers to the cu...
