Water-saving green drip irrigation cultivation method of facility melons

Abstract

The invention discloses a water-saving green drip irrigation cultivation method of facility melons. The cultivation method comprises the steps of building a micro-nano bubble oxygen-adding drip irrigation system, a solar heating system, a greenhouse structure and a disease and insect pest green prevention and control system. Micro-nano bubble water generated through a micro-nano bubble generatingdevice has a high dissolution capacity, the absorption and utilization of crops to fertilizer can be improved, the fertilizer applying amount is reduced, and a desalination salt separation area is formed in a root area; before the crops are planted, by conducting micro-nano bubble water drip irrigation with the assistance of an ultrasonic sterilizing lamp to sterilize and disinfect soil and air, breeding and propagation of pests can be effectively controlled. In the cultivation process, water-fertilizer-air integrated irrigation by adding oxygen through the micro-nano bubble water is conductedwith the assistance of a compound EM fungicide, and the high yield and good quality can be guaranteed while the utilization rate of the fertilizer is increased, the soil salinization and ventilationare improved, and the irrigation amount is saved.

Description

technical field [0001] The invention belongs to the technical field of agricultural water-saving cultivation, and in particular relates to a water-saving green drip irrigation cultivation method for facility melons and fruits. Background technique [0002] At present, in the cultivation process of vegetables and other facility crops, the annual amount of farmyard manure application can reach 75-150t / hm 2 , the applied salt substances can reach 515.57-6177.96kg / hm 2 . Calculated according to the above data, the content of sodium ions and chloride ions in the vegetable field can reach 10%-30%, which will cause the salt content in the soil to increase, and the nitrate content in it will be 30-60 times higher than that in the open field, and the soil will be seriously alkalized . The salinization of facility soil caused by excessive fertilization has become a common phenomenon, resulting in continuous cropping obstacles, serious pests and diseases, and reduced vegetable quali...

Problems solved by technology

The bio-fertilizer made of fruit peels used in the cultivation process of this method is not polluted, but it is required to be carried out on black soil with high organic matter content. The pre-treatment time of each soil is as long as 6 months, and it needs to be treated frequently after sowing. The peel of the fruit, and no prevention and control measures for soil-borne diseases are proposed, so it is not suitable for large-scale promotion and application in facility cultivation.

[0004] Based on the unreasonable irrigation method, irrigation amount, fertilization amount, irrigation water temperature and irrigation and fertilization frequency in the prior art, which lead to soil compaction, poor ventilation, soil salinization, and serious soil-borne diseases, the present invention proposes A water-saving green drip irrigation cultivation method for facility melons and fruits suitable for popularization and application in facility cultivation, with good water-saving effect, avoiding soil salinization, and achieving long-term high-yield, high-quality green production goals
