A formula substrate for industrialized seedling raising of vegetables

Abstract

The invention relates to the technology of seedling raising of vegetables and in particular provides a formula substrate for industrialized seedling raising of vegetables. The formula substrate for industrialized seedling raising of vegetables contains 950-1050L of turf, 160-180L of perlite, and 20-30L of water. Turf, perlite and water are mixed uniformly by using a special mixer for vegetable seedling raising substrates and are bagged for later use. The EC value is 0.3-0.5mS.cm<-1>. The concentration of a nutrient solution varies from 50ppm to 250ppm with the types of seedling raising and different growth periods and vigor. The formula substrate for industrialized seedling raising of vegetables facilitates water absorbing and rapid growth in periods of seed germination and seedling cotyledon of vegetables and has the advantages of uniform seedling germination, high growth speed and high sound seedling index.

Description

technical field [0001] The invention relates to vegetable seedling raising technology, in particular to a formula matrix for industrialized vegetable seedling raising. Background technique [0002] Soilless cultivation refers to the method of irrigating with substrate or nutrient solution without using natural soil. It is mainly used in the cultivation of vegetables and other crops. It is a high-yield and high-quality advanced technology that saves water, fertilizer and labor. In the middle of the 19th century, it began to be used in agricultural production in the 1930s. It was widely used in the Netherlands, Japan, New Zealand, Italy and other countries. At present, soilless cultivation technology has been applied and developed in more than 100 countries around the world. [0003] The research and application of soilless cultivation technology in my country started relatively late, but the relatively primitive soilless cultivation technology has a long history.

Problems solved by technology

[0006] Aiming at the above-mentioned defects of the existing vegetable seedling raising technology, the invention provides a vegetable seedling raising formula matrix, which solves the problem that the traditional vegetable seedling raising matrix has poor permeability, heavy quality, inconvenient long-distance transportation, and is not suitable for large-scale industrial vegetable seedling raising. At the same time, it also solves the problem that the high EC value of the substrate affects the water absorption and rapid growth of crop seed germination and seedling cotyledon stage, and does not meet the law of seedling growth and development that requires fertilizer from less to more fertilizer absorption.
