Greenhouse film management

If it is too long, it will cause the branches and leaves to grow and affect the differentiation of flower buds. During the mulching period, when it is not raining, the shed film should be rolled up to allow it to receive more sunlight and dissipate the sultry heat to enhance photosynthesis, facilitate nutrient accumulation, and improve fruit coloring and quality; but be sure to cover and restore before raining .
