Celery nutrient solution which can achieve water supply and topdressing simultaneously and preparing method thereof

Abstract

The invention discloses a celery nutrient solution which can achieve water supply and topdressing simultaneously. The celery nutrient solution is prepared from, by weight, 0.5-1.5 parts of macroelements, 0.002-0.01 part of microelements, 0.05-0.5 part of active materials and 500-2,000 parts of deionized water. The preparing method of the celery nutrient solution comprises the steps of preparing the macroelements, microelements and active materials into mother liquor A, mother liquor B and a mixture C respectively, mixing the mother liquor A and the mother liquor B according to the weight partsof the macroelements and the microelements, then adding the mixture C according to the weight ratio of the active materials, and uniformly stirring to obtain the nutrient solution. The nutrient solution is provided specifically aiming at soilless culture of celeries, and the requirement of the celery growth process for various elements can be met, so that the obtained celeries have thick stems, short internodes, large leaves and developed root systems; full play can be given to the productivity potential of crops, growth of new roots and differentiation of vascular bundle systems can be promoted, and less moisture is consumed; compared with soil culture, the yield is increased by 30%, and the development of agricultural modernization is promoted.

Description

technical field [0001] The invention belongs to the field of agricultural technology development, and in particular relates to a celery nutrient solution and a preparation method thereof capable of realizing simultaneous water supply and topdressing. 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 b...

AI Technical Summary

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
