What are the technical advantages of dense planting cultivation of potatoes in wide ridges?
China has a history of more than 400 years of potato cultivation, but what continues to this day is still the 65cm narrow-ridge potato planting method, with an average yield of 26,000 kg/hm. This planting method results in shallow hilling, insufficient soil storage capacity, tubers that are easily exposed, and an increase in deformed tubers. At the same time, because the ridge spacing is small and the plants are large, the spaces between ridges become congested, which is unfavorable for ventilation, makes humidity too high, and forms a field microclimate, making it extremely easy for the devastating disease -- potato late blight -- to occur and spread, producing large numbers of diseased tubers and even causing total crop failure.
