The experiment was carried out in Xingxian Agricultural Cooperative in Pengxi County, Sichuan Province. a-naphthalene acetic acid is formulated with Shanghai Agricultural Products Factory 150ppm liquid, spray directly, the treatment is divided into two sections, and for the comparison of the effectiveness of observation. 1. Seedling treatment Pumpkin seedlings in the third leaf just sprayed once sprayed once again when the fifth leaves issued a spray, the two time interval of 11 days. Treated pumpkin seedlings a total of three nest count 6, the same litter and untreated 6 as a control. The results of the growth and development are as follows: a) After the pumpkin seedlings were sprayed, the elongations of the stems and cranks were very fast, with an average elongation of 22 days after the second injection being 2.8 inches per day and 1.6 liters per day for the untreated ones; b) Pumpkin Miao life is more prosperous, manifested in the water than the untreated
