Grape seedlings should be managed well in May and June, and a bumper harvest in the second year can only be guaranteed.

The healthy and rapid growth of grape seedlings in the same year has a direct impact on the hanging fruit and bumper harvest in the second year, so it is very important to do a good job in this stage of management. May is coming soon. The following editor will share the management measures of grape seedlings for nearly a month or two.

Wipe the buds and pick the heart in time

When the newly planted grape seedlings grow to 20 cm from the bottom of the steel wire, they should pick the heart in time. After picking the heart, the secondary shoots that germinate one after another, leaving 4 buds at the top, and the rest of the secondary shoots will be removed with 1-2 leaves.

Reasonable topdressing

Topdressing was carried out when the seedlings grew to more than 6 leaves. At first, urea could be applied only to 5 kg per mu, and then the application rate was gradually increased according to the growth potential.

Generally apply once every 10-15 days per mu, watering and replenishing water in time after fertilization, grasp the principle of "spreading evenly, applying thin fertilizer frequently", so as to avoid hypertrophy and root injury.

For the weak grape seedlings, root promoter can be used to irrigate the roots to promote the growth of new roots.

Timely use of drugs to control diseases and insect pests

The absence of diseases and insect pests is the premise and guarantee for the rapid growth of grape seedlings.

May is still the high incidence period of black pox, we should focus on prevention, and master the principle of prevention every 4-5 days, 7-10 days in sunny days, and once every time it rains. Kaifu, Fuxing, carbendazim and Dyson zinc can be used alternately.

In June, downy mildew broke out one after another, which can be controlled by enoylmorpholine, Anke, DuPont dew and other agents. At the same time, we should also pay attention to the application of fenitrothion or dichlorvos or 3000 times of the enemy to control the wing moth.

At the same time of disease prevention, attention should be paid to the addition of foliar nutrient fertilizer, which is beneficial to promote seedling growth and flower bud formation, and lay a good foundation for fruit harvest in the second year.
