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

Abstract

The invention discloses a plant nutrient solution for Chinese cabbages. The plant nutrient solution comprises, by weight, 0.5-1.5 parts of macroelements, 0.002-0.01 part of microelement, 0.05-0.5 partof active substance and 500-2000 parts of deionized water. A preparation method of the plant nutrient solution includes preparing a mother solution A, a mother solution B and a mixture C from the macroelements, the microelement and the active substance respectively, mixing the mother solution A with the mother solution B according to the part-by-weight of the macroelements and the microelement, adding the mixture C according to the weight ratio of the active substance, and evenly stirring to obtain the nutrient solution. The plant nutrient solution and the preparation method thereof have theadvantages that the plant nutrient solution special for soilless culture of the Chinese cabbages can meet demands for various elements during growth of the Chinese cabbages, and the obtained Chinese cabbages have thick stems, short internodes, large leaves and strong root systems; potential productivity of crops can be fully developed, differentiation of new roots, new wounds and vascular bundle systems can be promoted, and consumed moisture is less; yield is increased by 30% as compared with that of soil culture, and agricultural modernization is promoted.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a plant nutrient solution for Chinese cabbage 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 adjusted. The...
