Root system nutrition carrier and preparation method and application thereof

Abstract

The invention relates to a root system nutrition carrier used for seedling cultivating or fertilizer retention and water storage of economic plants, which contains the main components of natural plant organic materials and innocuous and degradable bonding agent and has the advantages of molding, light weight, looseness, good ventilation and strong water and fertilizer retention capacity; the pore density of the carrier is 70-95 percent, wherein the capillary pore is 40-60 percent, the water absorption ratio is 1.5-4.5, the cation exchange capacity is 10-20meq / 100g, and the pH is 6.0-7.0. The preparation method comprises the following steps: the natural plant organic materials after being fermented and the bonding agent are mixed and stirred by weight proportion of 2-20:100 and molded within the temperature range of 20-100 DEG C. The root system nutrition carrier is mainly applied in a seedling cultivating root system nutrition pot for the sowing, the sticking, the tissue culture, and the like of fruit trees, vegetables, flowers, forests, traditional Chinese medicinal materials and economic plants and a fertilizer retention and water storage nutritional pot of perennial woody plants.

Description

technical field [0001] The invention relates to a root nutrition carrier, in particular to a nutrition carrier with good fertilizer retention, water storage, shaping, lightness, softness and ventilation. Background technique [0002] China is a major horticultural country in the world. The planting area and total output of horticultural crops in our country rank first in the world. The industrial seedling cultivation of fruit trees, vegetables, flowers, forest trees, Chinese medicinal materials and cash crops has become a high-efficiency industry in agricultural production. The domestic market requires Calculated in hundreds of millions. However, the seedling quality produced by the current seedling raising method is poor, the root system is underdeveloped, the survival rate of transplanting is low, the time for seedling slowing down is long, the annual supply cannot be provided, and the transportation cost is high; my country is one of the countries that are extremely short...

Problems solved by technology

However, the seedling quality produced by the current seedling raising method is poor, the root system is underdeveloped, the survival rate of transplanting is low, the time for seedling slowing down is long, the annual supply cannot be provided, and the transportation cost is high; my country is one of the countries that are extremely short of water resources in the world. The per capita water resources are less than 1 / 4 of the world's average level, and the water demand of major economic crops is not coordinated with natural precipitation; the soil foundation is poor, the organic matter content is low, the soil structure is poor, and the number of beneficial microorganisms is small, which leads to economic Problems such as underdeveloped root system of crops, weak growth potential, low yield, poor quality, and low utilization rate of fertilizer and water
