AbstractThis paper summarized the eficient rotation model and key cultivation techniques of muskmelon and autumn potatoes in Sanmen County，Zhejiang Province.In terms of crop scheduling， muskmelons were sown in mid-to一 late December，transplanted in early Januaryof thefolowing year，and harvested from early April to the end of July. Autumn potatoeswere sown inmid-Septemberand harvested inearly December.Keycultivation techniques for muskmelons include selecting varieties with strong resistance and good marketability，such as Dongfangmi No.1，and applying suffcient base fertilizer; using nutrient bowl seedlings with controlled temperature and humidity;adopting a double-vinecreeping cultivationmethod;implementing integrated waterand fertilizermanagement in the field with reasonable topdressing;improving fruitsetthrough pruning，fruit thinning，and asisted polination；and implementing integrated pest management.Keycultivation techniques forautumn potatoes include selecting the local Xiaohuangzhong variety，disinfecting and pre-sprouting the seed tubers，thoroughly cleaning the fieldanddeep plowing before sowing without applying basefertilizer;sowing atadensityof 5OO to55OO seeds/667m;focusing onseedling control infield management，timelytopdressingandirigation，intertilageand hilling;andfocusingonthecontrolofearlyblight，late blight，and undergroundpests.Thisrotation model yields significant economic benefits （net income increasedby 2 800 yuan/667 m2 compared to monocropped muskmelon）， prominent ecological benefits （improved soil structure， efcientutilization ofresidual potassium from muskmelons，reduced soil-borne diseases and pesticideapplication），and good social benefits （increased employment opportunities，ensured localpotato suppy）.This study provides areference for crop rotation cultivation in relevant regions.
