Embodiment Construction

[0021] The cultivation method of the present invention uses upper and lower layers of cultivation utensils, and the lower layer is a non-leakage utensil for assembling clear water with better nutrient solution. The upper layer and the lower layer are separated by a grid to facilitate the ventilation of the upper layer matrix. The upper layer and the lower layer are connected by cloth tape or rope, so that the liquid in the lower layer can use the physical siphon phenomenon and enter the upper layer. The upper layer is equipped with an inorganic cultivation medium, mainly composed of perlite, supplemented by small ceramsite and vermiculite, and the water-air ratio of the root system is adjusted with small ceramsite and vermiculite to facilitate the growth of the root system. Perlite has the characteristics of constant water absorption, and the water absorption is 4 times its own weight. When there is liquid in the lower layer, perlite can absorb the liquid in the lower layer in...

Abstract

The invention discloses a self-suction type soilless cultivation method. According to the cultivation method, cultivation appliances arranged in an upper layer and a lower layer are used, the upper layer is superposed on the lower layer, a certain distance is kept between the upper layer and the lower layer, the cultivation appliance containing an inorganic cultivation matrix for cultivating a plant is arranged in the upper layer, and a through hole is arranged at the bottom of the upper layer; a non-leakage appliance containing a nutrient solution or clear water which is well mixed is arranged in the lower layer; a connecting cloth tape or a cloth rope is arranged between the upper layer and the lower layer, the bottom end of the cloth tape or the cloth rope is immersed in the nutrient solution in the lower layer, and the top end of the cloth tape or the cloth rope is mounted in the inorganic cultivation matrix in the upper layer, so that liquid in the lower layer can be inspired into the inorganic cultivation matrix in the upper layer for providing nutrients for the plant by utilizing a physical siphon phenomenon. The self-suction type soilless cultivation method disclosed by the invention is simple and convenient to implement, so that a new sanitary and convenient way is developed for growing flowers by people in families.

Description

technical field [0001] The invention relates to a self-suction soilless cultivation method. Background technique [0002] Soilless cultivation is a method of growing plants in solution without soil, including hydroponics and sand cultivation. In the mid-19th century, W. Knop and others developed this method. By the 1930s, this technology began to be applied to agricultural production. In the 21st century, people further improved the technology, making soilless cultivation develop. [0003] Historically, the symbol of agricultural civilization is the degree of human intervention and control over crop growth and development. Practice has proved that it is relatively easy to control the environmental conditions of the aboveground part of the crop, but it is very difficult to control the underground part (root system control) under conventional soil culture conditions. The emergence of soilless cultivation technology has enabled human beings to obtain the ability to precisel...
