Problems solved by technology

At present, there are only a few types of formulas widely used in China, such as Knop classical hydroponic formula, Japanese garden test and Yamazaki nutrient solution formula. Low yield and poor quality in soil cultivation
Compared with developed countries, there is still a big gap in the nutrient solution of soilless cultivation of fruits and vegetables in my country, which limits the development of soilless cultivation technology to a large extent.

Abstract

The invention discloses special soil-less cultivation nutrient solution for lettuces and a preparation method of the nutrient solution. The special soil-less cultivation nutrient solution comprises macro-elements, microelements and water, the macro-elements include nitrogen, phosphorus, potassium, calcium, magnesium and sulfur, and the microelements include ferrum, manganese, copper, zinc, boron and molybdenum. The special soil-less cultivation nutrient solution is reasonable in component, rich in nutrition, wide in raw material source, low in cost and contains various nutrient elements and the microelements needed by growth and development of the lettuces, so that the lettuces can healthily and strongly grow, surviving rate of transplanting stock of the lettuces is increased, quality of fruits and vegetables is improved, so that yield and quality are improved, and raw materials are easily obtained. The preparation method is reasonable, simple and practicable in process, high in efficiency, low in application cost, simple to operate, easy to implement, convenient to use and convenient and rapid in application and has high application prospects.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and more specifically, the invention relates to a special soilless cultivation nutrient solution for lettuce and a preparation method thereof. Background technique [0002] Soilless cultivation refers to the planting technology that does not use natural soil to cultivate plants, but uses nutrient solutions containing elements necessary for plant growth and development to provide nutrition and enable plants to complete the entire life cycle normally. It has changed the traditional planting habit of agricultural production relying on soil since ancient times, greatly promoted the vigorous development of modern agricultural science and technology, and promoted the transformation of agricultural production to a new stage of industrial production and commercial production, with broad market prospects . [0003] Soilless cultivation replaces the soil environment with the artificially created...
