Problems solved by technology

The existing soilless culture nutrient solutions are not very targeted. Many flowers 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 capable of meeting soilless culture requirements of rhododendron. The plant nutrient solution is prepared from, by weight, 0.5-1.5 parts of massive 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 preparation method of the plant nutrient solution comprises the steps that the amother solution A, a mother solution B and a mixture C are prepared from massive elements, the trace elements and the active substances respectively, the mother solution A and the mother solution B are mixed according to the weight parts of the massive elements and the trace elements, then the mixture C is added in the weight proportion of the active substances, stirring is uniformly conducted, and then the nutrient solution is obtained. The nutrient solution is specially used for the soilless culture of the rhododendron and capable of meeting the requirements for various elements in the growth process of the rhododendron, the rhododendron obtained by using the nutrient solution is short in stem and internode, large in leaf and developed in root system; the productive potential of crops can be given full play to, the emergence of new roots and the differentiation of a vascular bundle system can be promoted, and less water is consumed; compared with soil culture, the yield is increasedby 30%, and the agricultural modernization development 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 suitable for soilless cultivation of rhododendrons 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 artificiall...
