Abstract

The invention discloses a preparation method of a water-retention and fertilizer-maintenance soilless culture medium for spinach. The preparation method comprises the following steps: soaking medicalstones in a sodium hypochlorite solution, stewing, washing the medical stones with water, adding coconut shell charcoal, straw powder and wheat bran, and uniformly mixing and grinding the materials toobtain a first premix; mixing acrylic acid with a sodium hydroxide solution, carrying out heating stirring, adding acrylamide for continuous uniform stirring, adding fibroin and the first premix, carrying out heating stirring, and filtering and drying the mixture to obtain a second premix; uniformly mixing wormcast, tea seed meal and the second premix, and disinfecting the mixture to obtain the water-retention and fertilizer-maintenance soilless culture medium for the spinach. The obtained soilless culture medium is good in water retention and fertilizer maintenance effect; the waste of resources is reduced, and the economical benefit is increased; moreover, the problems of high production cost of conventional soilless culture and pollution to the environment can be also solved.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation substrates, in particular to a method for preparing a soilless cultivation substrate for water- and fertilizer-retaining spinach. Background technique [0002] Spinach belongs to the genus Spinach of Chenopodiaceae. It is widely planted in spring, autumn and winter in urban and rural areas in my country. It is an important green leafy vegetable and export vegetable in my country. Spinach has high nutritional value and is rich in vitamin B1, vitamin B2, vitamin C, carotene, protein, folic acid, and minerals such as iron, calcium, and phosphorus. It is known as the "king of vegetables" by Arabs. [0003] Spinach soilless cultivation has become the main form of spinach planting due to its inherent advantages of saving fertilizer, water, labor, medicine, high yield, high quality and cleanliness. However, the commonly used nutrient solution matrix has a poor water and fertilizer retention...
