Substrate package overhead burial and overwintering cultivation system and method

Abstract

The invention discloses a substrate package overhead burial and overwintering cultivation system and method. The cultivation system comprises a substrate groove and a substrate package placed in the substrate groove, the groove bottom of the substrate groove is provided with an overhead part, the substrate package is overhead on the overhead part, a liquid storage layer is formed between the groove bottom of the substrate groove and the bottom of the substrate package, the liquid level of the liquid storage layer is lower than the overhead height of the substrate package, and the open top of the substrate groove covers a light-transmitting film or a light-transmitting plate which is favorable for causing the inside of the substrate groove to receive solar thermal radiation to increase thetemperature. Compared with the prior art, the substrate package is overhead, to prevent a macerating root phenomenon. At the same time, the substrate groove is covered with the light-transmitting filmor the light-transmitting plate. Accumulated liquid of the liquid storage layer is heated in the daytime, and when it is at an extremely low temperature at night, the accumulated liquid can release heat, to protect roots from low temperature obstacles. The cultivation method is simple to operate, the plant growth can be promoted in winter, the fruit development cycle is shortened, the abortive fruit rate is reduced, and the cultivation efficiency is improved.

Description

technical field [0001] The invention relates to a cultivation device, in particular to a system and method for overwintering cultivation system and method for overwintering with a matrix package. Background technique [0002] In substrate cultivation, substrate temperature has a great influence on plant growth, especially in winter, too low ambient temperature has a great influence on substrate temperature, which is often lower than the temperature suitable for root growth, which affects the growth and development of plants to a large extent. production formation. Therefore, creating a temperature suitable for root growth is the technical key to solving overwintering cultivation. [0003] There are two main types of traditional substrate (overwintering) cultivation. The first method is: place the substrate bag directly on the ground surface, so that the substrate bag is directly exposed to the external environment, the temperature difference between day and night is large, ...

Problems solved by technology

In addition, the PPE board or film is usually waterproof, so when water and nutrient solution are dripped into the substrate, the bottom of the substrate groove will usually form an accumulation of fluid, which may cause retting. In addition, under the same low temperature environment , the effusion will make the temperature of the substrate lower than that of the substrate without effusion (that is, in the air), and the root system will be hypoxic, which will affect the growth rate of the root system, and even cause the root system to be hindered by low temperature
