Embodiment Construction

[0023] Further illustrate the present invention below in conjunction with accompanying drawing and embodiment.

[0024] 1. Cultivation tank

[0025] Use bricks to make the cultivation tank, the tank width is 50cm, the height is 35cm, and the groove spacing is 70cm. Between the first and second bricks, fill the film with coarse slag with a thickness of 5 cm and a diameter of 2 cm, then cover it with a clean woven bag, and then code two layers of bricks.

[0026] 2. Cultivation substrate

[0027] Rice husk, sawdust, peat and vermiculite were used as the substrate. The former two were decomposed at high temperature before use. The vermiculite was soaked in 15% sodium hypochlorite solution for 30 minutes and then rinsed with clean water before use. 1 day before sowing, water the substrate thoroughly. Add peat, sawdust, rice husk and vermiculite in a volume ratio of 2.0︰3.0︰3.0︰2.0 to each cultivation tank (the depth is 25cm), and add 15kg / m at the same time 3 Disinfected chick...

Abstract

The invention discloses an organic and ecological soilless culture method for spinaches. The organic and ecological soilless culture method for the spinaches comprises the following steps of (1) preparation of a matrix, (2) sowing and seedling raising, (3) thinning, and (4) later maintenance. The matrix is prepared by a method comprising the following steps of mixing grass carbon, sawdust, rice hulls and vermiculite with a volume ratio of 2.0:3.0:3.0:2.0; and adding 15kg of chicken manure and 8kg of cake fertilizers in per cubic meter of the matrix. By the organic and ecological soilless culture method for the spinaches, the production cost of the spinaches can be reduced, pollution on the environment is reduced, and the yield and the quality of the spinaches are improved. The organic and ecological soilless culture method for the spinaches is suitable for Chinese situations, and conforms to the development direction of ecological agriculture and circular economy.

Description

technical field [0001] The invention relates to a high-yield, high-quality, high-efficiency and high-efficiency cultivation method for vegetable crops, in particular to an organic ecological soilless cultivation method for spinach. Background technique [0002] Soilless cultivation has become an important content of protected horticulture and the main form of industrial production of horticultural crops due to its inherent advantages of saving fertilizer, water, labor, medicine, high yield, high quality, and cleanliness. However, the commonly used nutrient solution soilless culture method has a high production cost, and the problem of environmental pollution is difficult to solve. The organic ecological soilless cultivation technology uses organic ecological substrates instead of soil, and does not use traditional nutrient solutions to irrigate plant roots, but uses organic solid fertilizers to directly add water to promote crop growth. Its advantages are very prominent, th...
