Problems solved by technology

At present, there are too few types of cultivation substrates in China and the performance of the substrates is uneven, which seriously restricts the popularization of roof greening. Therefore, it is urgent to develop a special substrate for roof greening with strong water retention, small bulk density, loose air permeability, light weight and no pests and diseases.

Abstract

The invention relates to the technical field of plant cultivation, and provides a preparation method of a water retention light nutrition medium suitable for arid area roof greening. The plant cultivation medium comprises, by weight, 30-50 parts of rotten organic waste, 20-40 parts of garden soil, 10-30 parts of kaolin and 4-6 parts of ceramsite. The cultivation medium is high in water retention capability, low in bulk density, loose, ventilated, light and free from diseases and insect pests and can increase survival rate of plants, a roof is effectively greened, city greening quantity is increased, and a micro-climate environment is adjusted. The preparation method of the plant cultivation medium includes the steps: mixing and crushing the rotten organic waste, the garden soil and the kaolin into particles; placing the ceramsite on an uppermost layer. The preparation method is simple in technique and high in operability, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a horticultural plant cultivation substrate, and more particularly to a method for preparing a water-retaining light-weight nutrient substrate suitable for roof greening in arid areas. Background technique [0002] With the acceleration of social urbanization, cement buildings occupy a dominant position in urban space, the heat island effect is becoming more and more obvious, and air pollution is becoming more and more serious, especially in arid areas, where sandstorms are raging. In order to increase the green area, the roof The need for greening is even stronger. The most critical material for green roofs is the green substrate. [0003] In the arid area of ​​western my country, due to the constraints of economic development, technical level and degree of attention, the research, development and utilization of the roof greening cultivation substrate has just begun. ...
