Novel blueberry container cultivation method

Abstract

The invention discloses a container and a method for blueberry container cultivation. The cross sectional area of an opening of the container is larger than that of the bottom; a drain hole is formed in the bottom of the container; a drain pipe connected with the drain hole is arranged at the bottom of the container; the drain pipe is connected with a liquid recovery pipeline; an upper opening of the container is covered with a flexible film with a hollow center; according to the novel method for blueberry container cultivation, a cultivation container, a cultivation medium, nutrient solution circulation equipment and a nutrient solution are included. The method has remarkable advantages in the aspect of blueberry potting in the solar greenhouse, and the requirements for environment humidity control, plant growth amount and fruit yield can be met at the same time. And after one-time investment, the later-period management cost and the continuous investment cost are relatively low, so that the method can be widely applied to industrial planting.

Description

technical field [0001] The invention belongs to the field of fruit tree cultivation, and specifically designs a new method for container substrate cultivation. Background technique [0002] The scientific name of blueberry (Vaccimium spp) belongs to the Rhododendron family bilberry (or bilberry subfamily), also known as blue berry. Anthocyanins with extremely high oxidative activity have high nutritional and health care effects, and are a new type of functional fruit. my country's blueberry cultivation started relatively late. Since 1983, it has been introduced and carried out cultivation research work. In recent years, it has developed rapidly and has initially formed industrialized cultivation. [1] . As a third-generation emerging fruit tree, the cultivation and management of blueberry is obviously different from other fruit trees. In recent years, the substrate pot cultivation method is regarded as a new cultivation method. However, this container cultivation method h...

Problems solved by technology

However, this is difficult to achieve in actual production, and once the drip irrigation speed is uneven, or even the drip irrigation head is damaged or blocked, it will directly lead to the death of seedlings due to lack of water.

In addition, this drainage method will discharge a large amount of waste nutrient solution with high salt content into the soil. Even if the waste liquid recovery system is used for recycling, the water in the substrate will evaporate too quickly due to the large opening area above the container, which will affect the soil. Surrounding air humidity increases the probability of blueberry infestation with botrytis
