Early harvest does not reduce fruit firmness, soluble solids content and single fruit weight, but can increase fruit price by 0.30-0.80 yuan / kg, and the economic benefit is remarkable. The suitable concentration for pre-harvest spraying is 100-150 mg / kg for early-maturing varieties and 200 mg / kg for middle-maturing varieties.
