Soilless culture nutrient solution for leafy mustard and method for preparing soilless culture nutrient solution

Abstract

The invention discloses soilless culture nutrient solution for leafy mustard. The soilless culture nutrient solution comprises, by weight, 0.5-1.5 parts of major elements, 0.002-0.01 part of trace elements, 0.05-0.5 part of active substances and 500-2000 parts of deionized water. A method for preparing the soilless culture nutrient solution includes preparing mother liquor A, mother liquor B and mixture C from the major elements, the trace elements and the active substances; mixing the mother liquor A and the mother liquor B with each other according to the weights of the major elements and the trace elements; adding the mixture C into the mother liquor A and the mother liquor B according to the weight proportion of the active substances; uniformly mixing the mother liquor A, the mother liquor B and the mixtures C to obtain the soilless culture nutrient solution. The soilless culture nutrient solution and the method have the advantages that requirements on diversified elements of the leafy mustard in growth procedures can be met by the soilless culture nutrient solution specially for carrying out soilless culture on the leafy mustard, and accordingly the leafy mustard has thick stems, short internodes, large leaves and developed root systems; production potential of crops can be sufficiently released, differentiation of new root and cut and vascular bundle systems can be promoted, the soilless culture nutrient solution is low in water consumption, the yield can be increased by 30% as compared with soil culture, and development of agricultural modernization can be 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 for big-leaf mustard 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 ad...

Problems solved by technology

The existing soilless culture nutrient solutions are not very targeted. Many vegetables and 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 it is necessary to design different nutrient solutions according to the characteristics of different plants. Nutrient solution However, there is no relevant research in this area
