摘要：This experiment used high-efficiency, wide-coverage and long-range power sprayers to spray pesticide solution during the later stage of rice growth. It measured the quantity of pesticide sediment, then analyzed and studied the distribution pattern of pesticide sediment on the rice plants and the sediment ratios in the rice field. This experimental study indicates:spraying pesticide solution results in relatively high sediment distribution ratios; the upper parts of the rice plants are most able to receive the pesticide solution; this new sprayer model sprays evenly and penetrates well, effectively improving sediment quantity of pesticide solution on the middle and lower parts of the rice while reducing pesticide quantity.
