A New Method for High-yielding Cultivation of Potato
In order to simplify the traditional potato planting technology, reduce labor intensity, reduce labor force, reduce production cost and improve planting efficiency, we carried out the experimental demonstration of potato "four don 'ts" planting technology, which is summarized as follows. 1. Technical advantages 1. Save labor and effort. Compared with the traditional method, the technology has four changes: one is to change ploughing to no-tillage; the other is to change digging holes to sowing on soil; the third is to change intertillage to weeding; the fourth is to change digging to picking potatoes
