The invention relates to an unlimited shaping 
pruning fruit-bearing high-yield precocity method for 
greenhouse cultivation of melons. The unlimited shaping 
pruning fruit-bearing high-yield precocity method comprises the following steps: hoeing to preserve 
moisture of soil before a melon 
seedling grows to be 50cm, when the melon 
seedling grows to be 50cm, retaining a main 
vine and a strong side 
vine, completely removing side buds and side vines, suspending the main 
vine, leaving the side vine on the ground to grow, retaining stubbles to bear fruits when the main vine grows to be 80-100cm, retaining 3-4 adjacent joints to retain stubble and bear fruits, retaining one leaf before the fruits and pinching, pinching the main vine when the main vine grows to be 160-180cm, retaining only one living 
branch at the top, completely removing other side stubbles and side buds, selecting and retaining melons when melons grow and expand until the diameters are 4-6cm, retaining two small melons, and removing other small melons and side stubbles. By adopting the unlimited shaping 
pruning fruit-bearing high-yield precocity method, by retaining 
nutrient vines, the 
photosynthesis areas of crops can be increased, 
nutrition can be sufficiently replenished to 
reproduction vines, the 
reproduction vines are prevented from premature senility, fruits on the premature senility vines can absorb relatively much 
nutrition and can rapidly develop and grow, and by increasing water and fertilizers at appropriate time, the purposes of precocity, high yield and high efficiency of 
greenhouse cultivation of melons can be achieved.
