Horticultural long-acting and slow-release straw nutritional soil as well as preparation method and using method of nutritional soil substrate

Abstract

The invention discloses horticultural long-acting and slow-release straw nutritional soil as well as a preparation method and a using method of nutritional soil substrate. In percentages by weight, the nutritional soil contains 20 percent of substrate and 80 percent of horticultural soil; the substrate contains 25 percent of perlite, 65 percent of rice straws or wheat straws, 2.0 percent of slow-release agent, 0.75 percent of calcined lime, 0.75 percent of straw well-rotten fungicide, 3.0 percent of nitrogenous fertilizer, 1.0 percent of pure phosphatic fertilizer, 1.75 percent of potassic fertilizer and 0.75 percent of microelement fertilizer; the preparation method of the substrate comprises the following steps: unbaling rice straws or wheat straws, putting under blazing sun for 3-4 days for sterilizing; crashing rice straws or wheat straws by a crasher into straw sections with the length of 0.8-1.2cm; and evenly mixing 25 percent of perlite, 65 percent of rice straws or wheat straws, 2.0 percent of slow-release agent, 0.75 percent of calcined lime, 0.75 percent of straw well-rotten fungicide, 3.0 percent of nitrogenous fertilizer, 1.0 percent of pure phosphatic fertilizer, 1.75percent of potassic fertilizer and 0.75 percent of microelement fertilizer to prepare the substrate, and packaging the substrate; and the using method of the nutritional soil comprises the following step: fetching 80 percent of horticultural soil and 20 percent of substrate in percentages by weight. The nutritional soil has no putrefactive odor and musty taste, synchronous straw fermentation rot and flower and plant growth as well as slowly-released nutritional ingredients, and keeps the activity and the self nutrient circulation for a long time.

Description

technical field [0001] The invention relates to horticultural nutrient soil and a preparation and use method of nutrient soil, in particular to a preparation and use method of horticultural long-acting slow-release straw nutrient soil and nutrient soil matrix. Background technique [0002] The soil for cultivating flowers is best collected from natural peat soil or natural forest humus, but random mining will undoubtedly cause damage to the environment. With the continuous increase of various flowers, the demand for gardening soil continues to expand, and natural peat soil or natural forest humus can no longer meet the growth of usage. [0003] Because crop straw contains a large amount of organic matter, nitrogen, phosphorus, potassium and trace elements, it is an important organic fertilizer source for agricultural production, and has the characteristics of low cost and environmental protection requirements. It is widely used in the preparation of flower nutrient soil and ...

Problems solved by technology

[0004] However, the existing flower nutrient soil has a series of defects when used: the fermentation process of using straw as the main organic material will undoubtedly greatly increase the cost and production cycle; the nutrient soil prepared after the fermentation of organic materials will inevitably have a rancid smell and Musty warehouse smell, especially the nutrient soil added with livestock and poultry manure, is not suitable for gardening soil for beautifying the environment
