Detailed Explanation of the Double-Row High-Yield Potato Cultivation Technique with Ridging
The double-row high-yield potato cultivation technique with ridging is a comprehensive high-yield potato cultivation technique based mainly on deep loosening, ridging with deep fertilizer application, and rational close planting in double rows. It generally increases yield by more than 15% compared with conventional flat-bed cultivation, and raises the marketable rate of qualified tubers by more than 20%. Main technical points: 1. Select suitable varieties. At present, the main varieties promoted for planting in the south are Sishu No. 1, Atlantic, Jinkou 303, Holland No. 7, Holland No. 15, Dongnong 303, Kexin No. 4 and other early-to-mid maturing, high-yield, high-quality potato varieties. 2. Strictly select the site and prepare the soil finely. Select

Key Points of Mechanized Intertillage and Ridging Technology for Potatoes
At present, it is exactly the intertillage stage of potato planting. To guide agricultural machinery operators in production, the precautions and troubleshooting of mechanized intertillage and ridging technology for potatoes are introduced as follows: 1. Adjustment methods (taking the 3ZF-4 model as an example) 1. Row spacing adjustment. Row spacing adjustment of the 3ZF-4 potato intertillage fertilizer applicator: taking the center line of the front crossbeam of the intertillage machine as the baseline, loosen the fixing screws on the main beam connecting the intertillage fertilizer applicator units on both sides, move the intertillage fertilizer applicator units, measure the spacing between the middle points of two adjacent shovel tips to the required size
