Description

A drip irrigation system for nutrient bowls

Technical field:

The invention belongs to the field of agriculture, in particular to a drip irrigation system for a nutrient bowl.

Background technique:

Drip irrigation is the use of plastic pipes to send water through orifices or drippers on capillary tubes with a diameter of about 10mm to near the roots of crops for local irrigation. It is currently the most effective water-saving irrigation method in arid and water-deficient areas, and the water utilization rate can reach 95%. Drip irrigation has higher water-saving and yield-increasing effects than sprinkler irrigation, and can be combined with fertilization to more than double the fertilizer efficiency. It can be used for irrigation of fruit trees, vegetables, cash crops and greenhouses, and can also be used for field crop irrigation in dry and water-deficient places. At the same time, in order to improve the survival rate of transplanted seedlings and reduce the cost of migration, the nutrient pot planting technology for seedlings in the field was invented.

The problem with it is:

1. In order to prevent blockage of existing drip irrigation orifices or drippers, drip irrigation or micro-spraying is generally carried out above the soil layer near the root of the crop. If the control is not good, it is easy to cause mildew diseases and soil layer hardening caused by local over-humidity of the topsoil; Due to the limited volume of the nutrient bowl, it is also prone to the problem of loss without infiltration, resulting in waste of water and fertilizer. Patent CN201720600216.0 discloses a drip irrigation type plant root watering device, including a circular fixed plate and a circular cover plate above it, a liquid storage bin is formed between the fixed plate and the cover plate, and a liquid storage tank is formed at the center of the fixed plate and the cover plate. A channel for the trunk of the plant to pass through isolated from the liquid storage tank; a plurality of drainage pipes which are respectively connected to the liquid storage tank are evenly distributed under the fixed plate. The drainage tube is provided with a plurality of drainage side holes. The lower end of the drainage pipe is connected with a fork rod, which is convenient for inserting into the soil and keeps the circular fixed plate horizontal. The provided drip irrigation plant root watering device surrounds the plant roots in a circle, and is inserted into the ground through evenly distributed drainage pipes, and water is injected directly from the underground roots to avoid waste of surface loss and facilitate operation. However, the device is large in size and high in cost, and it is difficult to popularize and apply the installation, management and protection of high-density nutritional bowls in the field.

2. The nutrient bowl in the field lacks connection with the ground root system. When encountering strong winds, it is easy to lodging in a large area, causing losses.
