Abstract

The invention discloses a high-yield and high-efficiency greenhouse cucumber water, fertilizer and gas regulation and control method. The method is characterized in that a water and gas coupling technology is added on the basis of water and fertilizer integration, crop irrigation and fertilization are precisely and scientifically regulated and controlled, and precise supply and high-efficiency regulation and control of required water, fertilizer and gas can be carried out on greenhouse cucumbers. According to the method, rhizosphere water, fertilizer and gas environments suitable for healthy and strong growth of the greenhouse cucumbers are created, meanwhile, the method saves more water and fertilizer, the automation degree is high, and high quality and high yield of the greenhouse cucumbers are achieved.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to a high-yield and high-efficiency method for controlling water, fertilizer and gas of cucumbers in greenhouses, which is suitable for irrigation of cucumbers in greenhouses. Background technique [0002] Cucumber, Cucurbitaceae Cucumber is an annual plant. The fruit is rich in nutrition. It can be eaten raw as fruit or cooked as vegetable. The cultivation cycle is long, and the demand for fertilizer is large, especially during the flowering and fruiting period. The existing water-fertilizer integrated planting has many disadvantages. It only realizes water-fertilizer coupling and lacks the regulation of crop rhizosphere air, which leads to hypoxic stress, low fertilizer utilization rate, and reduced yield. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a high-y...
