Problems solved by technology

The existing soilless cultivation nutrient solutions are not very targeted. Many flowers often use the same nutrient solution when they are used in soilless cultivation. They do not know that different plants need different nutrients for growth, so different nutrients need to be designed according to the characteristics of different plants. However, there is no related research in this area

Abstract

The invention discloses a soilless culture nutrient solution applicable to kumquat. The soilless culture nutrient solution comprises the following components in parts by weight: 0.5-1.5 parts of macroelements, 0.002-0.01 part of trace element, 0.05-0.5 part of an active material and 500-2000 parts of deionized water. The preparation method comprises the following steps: respectively preparing a mother solution A, a mother solution B and a mixture C from the macroelements, trace element and the active material, and mixing the mother solution A and the mother solution B according to the weight parts of the macroelements and trace element; adding the mixture C according to a weight ratio of the active material, and uniformly stirring, thereby obtaining the nutrient solution. The nutrient solution targeted at soilless culture of kumquat is provided by the invention, so that the requirements on various elements in the kumquat growth process can be met, and the obtained kumquat is thick in stems, short in intermode, large in leaf and developed in root system; the potential productivity of crops can be fully achieved, new creation of new roots and differentiation of vascular bundle systems can be promoted, and less moisture is consumed. Moreover, compared with soil cultivation, the soilless culture nutrient solution disclosed by the invention has the advantages that the yield is improved by 30%, and development of agricultural modernization is promoted.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a soilless culture nutrient solution suitable for kumquats and a preparation method thereof. Background technique [0002] Soilless cultivation refers to the method of cultivating crops with nutrient solution or solid substrate plus nutrient solution without soil. It has changed the planting habit that agricultural production has relied on soil since ancient times, and pushed agricultural production to a new stage of industrialized production and commercial production. Its core is not to use natural soil. Plants are produced in cultivation devices filled with nutrient solutions or grown in solid substrates containing organic fertilizers or filled with nutrient solutions. This artificially created plant root environment can not only meet the needs of plants for mineral nutrition. , moisture and air conditions, and can be artificially controlled and a...
