When the buds grow to 2 ~ 3 cm, wipe off the weak buds, forked buds and useless hidden buds sprouted on the old vines. For twins or triplets, there is only one main bud left. If the load is insufficient, the double buds with inflorescences at the top of the mother branch can leave a large space.

(2) Fixed tip

When the new shoot length is10 ~ 20cm and the inflorescence can be seen. Varieties with low seed setting rate, large panicle and vigorous growth should leave enough fruiting branches. If the plant grows too vigorously or too weakly, with few bearing branches and insufficient load, a certain number of developing branches should be left besides all bearing branches.

(3) Choose the heart

Therefore, leaving 6 ~ 7 leaves in the inflorescence of lianas for coring can improve the fruit setting rate and promote the expansion of young fruits. Varieties that are prone to falling flowers and fruits, such as rose fragrance, should be picked 3 ~ 5 days before falling flowers. Varieties with high fruit-setting rate can be pitted after flowering.

(4) removing the second tip

After the new buds are cored, a large number of secondary buds will germinate. Therefore, it is necessary to control and not consume nutrition. There are no secondary branches under the inflorescence, except the top 1 ~ 2 secondary branches, and all the upper parts of the inflorescence are smoothed. 4 ~ 6 leaves with the remaining secondary branches were re-cored.

(5) Pinch inflorescence

Varieties with serious flower and fruit drop, or varieties with weak branches and vines, can pinch the inflorescence of 1/4 ~ 1/5 3 ~ 5 days before flowering to improve the fruit setting rate.

(6) Fruits and vegetables

For varieties with very tight ears and small and green fruit grains, they should be thinned before the fruit grains expand to increase the fruit grains and keep them neat.

(7) removing tendrils

Tendrils not only consume nutrients, but also wrap around spikes and vines, causing disorder of branches. So clear it in time. Generally, it is removed when removing the core, secondary shoots and vines.

(8) Shoot new buds

When the new shoots grow to 20 ~ 30 cm, the vines are bound, and the new shoots continue to grow throughout the growing period, 3 ~ 4 times a year. Don't cross the vines.
