In the conventional watermelon planting, planters are unquestioning at the beginning of seed selection and do not treat seeds well,
seedling management in the planting process is performed by experience,
pesticide application is unreasonable in the prevention and control of the pests, the conditions such as premature drop, blossom drop, crazy
seedling, fruit
cracking and the like occur in the planting process to influence the yield and quality of the watermelons, and simultaneously, the phenomenon of
pesticide residues is serious. Therefore, in order to improve the quality of the watermelons and provide the reference for the cultivation of the watermelons and the prevention and control of the pests, in the process of cultivation, fertilization control, the selection of the high-quality seeds and reasonable rotation of crops and
