Growing red quinoa in greenhouses is a great way to improve greenhouse soil

Greenhouse facilities block rain and dew all year round, and the fertilizers and materials applied with each round of planting accumulate over time, causing base saturation in the soil and creating cultivation obstacles. The only options are to soak the soil with large amounts of flowing water, or even to replace the topsoil entirely - both time-consuming and costly methods with poor results that seriously affect the harvest, becoming a nightmare for farmers.

A-Jun is a farmer who grows melons and fruits in greenhouses. He said: "The purpose of growing red quinoa is not for income or to follow the trend, but to improve soil salinization." Supported by some literature reports and experience, we were interested in this experiment, thinking it might find a solution for many farmers dealing with continuous cropping obstacles in greenhouses, which led to the collaboration between both parties.

Amid the busy journeys back and forth, we first provided red quinoa seeds and materials, and pointed out a few key growing points. Later communications, including techniques from seedling raising to harvest, could only be explained through "online teaching." Fortunately, with advanced technology, this "distance agricultural university" went fairly smoothly. The first batch of over a hundred jin of "greenhouse red quinoa" had bright-colored husks, rich functional components, and few fine stones and impurities in the stems and leaves, meeting high quality standards. It was a good example of "growing red quinoa successfully on the first try," and most importantly, the soil in the greenhouse gradually improved.
