Applicable varieties are Kyoho, Xianfeng, Jingya, Fujiminori, etc. The ear without stone fruit should be strictly drained, and the second ear should be picked about a week before flowering, and 3-6 branches at the base of the ear should be cut off, and the tip of the ear should be pinched off to keep about 5-6 branches of the remaining ear. The strong tip leaves one ear, and the weak tip is sparse. 2-3 days before flowering, soak the ear with seedless wine 1 (effective components are gibberellin, pyraclostrobin, thiabendazole, etc.). ) 2-3 seconds, and gently bounce the ear, shake off the excess liquid medicine, which can destroy the formation of seeds and produce seedless fruits. Because the seeds of fruits can produce endogenous hormones to promote fruit expansion, seedless fruits are smaller after 1 treatment, so it is necessary to supplement the cell activator sodium nitrophenolate and coordinate the supply of hormones to increase fruit particles. The treatment time and method are the same as the above-mentioned "fruit-increasing granules".

Before the second treatment, thin the fruit, thin the fruit inward and small, and leave 40-50 grains per ear. Jingya, Jufeng and Fujiminori varieties were sprayed with B+K (or potassium dihydrogen borate) on the leaves, and the grain weight was 12- 15g, the maximum was 32g, and the coloring was 7- 10 days earlier. The pulp is hard and crisp, the ratio of sugar to acid is high, the quality and flavor are good, and the price is much higher than that of the same variety.
