Problems solved by technology

However, due to the influence of the special greenhouse environment and artificial water and fertilizer management measures on the facility environment, the environmental conditions are closed, there is no natural rainfall, and the evaporation is large. Secondary salinization phenomenon, and soil salinization causes plant growth to be inhibited, affects crop yield and quality, and has a great impact on production

Abstract

The invention discloses a special nutrient liquid fertilizer for improving saline soil for melons, a preparation method thereof and a hydroponic method. Proline is added to the nutrient liquid fertilizer, and sodium glutamate and methyl p-hydroxybenzoate can also be added. The proline in the nutrient liquid fertilizer of the present invention cooperates with the nutrient elements of each component, which can prevent dehydration of plant cells after application, restore the function of the membrane system, keep the enzyme function on the cell membrane normal, make the metabolism proceed in an orderly manner, and have good membrane permeability , increase the rate of photosynthesis, increase the synthesis of assimilated products, and effectively prevent salt stress; through the combination of added components sodium glutamate and methyl p-hydroxybenzoate, it can further make the cultivated melons have a special fruity taste and stimulate melons The moisture in the inner pulp increases, and the pulp is full and crisp. At the same time, it effectively prevents diseases and insect pests during the seedling and vine stages of the melon, and avoids the situation of poor rhizome development, so that the fruit of the melon can expand rapidly when it bears fruit in the later stage, and the meat quality is significantly improved. The weight of the melon produced by the invention is more than 10% higher than that of the common melon, and the quality is excellent.

Description

technical field [0001] The invention relates to the field of facility agriculture, in particular to a nutrient liquid fertilizer. Background technique [0002] Today's facility agriculture is one of the most dynamic new industries in my country's agriculture. However, due to the impact of the special greenhouse environment and artificial water and fertilizer management measures on the facility environment, the environmental conditions are closed, there is no natural rainfall, and the evaporation is large. Secondary salinization phenomenon, and soil salinization inhibits plant growth, affects crop yield and quality, and has a great impact on production. [0003] At present, the improvement methods for saline soil are mainly through the combination of physical, chemical and engineering measures, and comprehensive measures are taken according to local conditions. However, the fundamental purpose of improving saline soil is to reduce the damage of salt stress to plant growth. ...
