Abstract

The invention relates to the field of plant cultivation and discloses hydroponic coffee nutrient solution and application thereof and a coffee water planting method. The nutrient solution comprises N, P, K, Ca, Mg, S, Zn, Cu, Mn, B, Mo, Fe and Cl, wherein the concentration ratio between ammonium nitrogen and nitrate nitrogen in the N is (3 to 7) to (7 to 3). By means of adjusting the composition of nutrient elements of the nutrient solution, the proportion of all the elements, the Cl concentration and the proportion of the ammonium nitrogen and the nitrate nitrogen in the N, the novel nutrient solution suitable for hydroponic coffee is obtained. The hydroponic nutrient solution solves the problem that the existing Hoagland nutrient solution is not suitable for the hydroponic coffee growth and causes the fact that coffee is weak in growth, improves the chlorophyll content, the biomass and the plant nitrogen content of the coffee and also ensures the aspects of the plant height, the stem diameter, the whole plant dry weight, the leaf dry weight, the stem dry weight, the root dry weight and the leaf area of the coffee to be in a better growth state.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a hydroponic nutrient solution and its application and a coffee hydroponic method. Background technique [0002] The coffee industry is an emerging industry for farmers in tropical mountainous areas in my country to get rid of poverty and become rich. By the end of 2012, China's coffee planting area exceeded 1.3 million mu, with an annual output of 69,000 tons of green coffee beans and an output value of 1.762 billion yuan. The coffee industry has become another characteristic emerging pillar industry after tobacco, sugar, tea, and gum. [0003] But at present, coffee is mainly planted in soil culture medium or sand culture medium. If the conditions are not suitable, it will often stop growing after transplanting, and the leaves will wilt, resulting in death. At the same time, the coffee root system is shallow, with many fibrous roots and fragile roots. Therefore, under field co...
