Sweet potato soilless tuber production system and method
ActiveCN117099668BImprove the level ofavoid threatsAgriculture gas emission reductionCultivating equipmentsEngineeringNutrient
The application discloses a sweet potato soilless tuberization cultivation system and method. In view of the fact that existing sweet potato production cannot get rid of solid substrates such as soil, and is restricted by upgrading of cultivation technology and product value positioning, the sweet potato soilless tuberization cultivation technology of the application adjusts the number and single weight of tubers by controlling environmental air pressure conditions. The cultivation system comprises a culture box and a regulation system, the culture box is divided into a nutrient bin and a tuberization bin, the tuberization bin is provided with seedling holes and has an airtight structure, and the regulation system monitors and regulates the culture conditions in the culture box. The culture method is a stage regulation culture technology, and the continuous long-term tuberization production can be realized through the tuberization period regulation culture. The application solves the key technical problem that all existing soilless cultivation technologies of sweet potato need to use solid substrates to press vines to induce tuber enlargement to realize tuberization, is a completely soilless cultivation technology of sweet potato, introduces the sweet potato cultivation technology into a new stage, and provides a scientific basis and production control means for stable small-scale sweet potato production.
