Management method of grape seedling raising

When planting grape seedlings, it is necessary to know the planting techniques of grape seedlings. The following is the management method of grape seedling planting that I have carefully arranged for you. Let's have a look.

Planting management method of grape seedlings

First, the management of grape branches and vines.

1, wipe the fork. In mid-July, the new shoots of grape seedlings grown by cutting grow to 40-50 cm. Some seedlings have several new buds or a new bud has several secondary buds, so they must be raked in real time to keep a strong new bud.

2. Choose your heart. When the new shoots of grape seedlings grow to about 50 cm, they begin to pick their hearts. All secondary tips propagated after coring were erased except one of the tips. When the secondary bud grows to 6 leaves, 3 leaves are left for coring, and all regenerated buds on the secondary bud are erased.

3, tie. The new shoots on the seedlings of higher grape varieties can be placed in 1.0- 1.5 meters, so the seedlings must be tied. You can insert a bamboo pole between two rows of seedlings every 3-4 meters and pull 2-3 rows of thin iron wire or nylon rope. Draw a line at each end of each bamboo pole. Tie two rows of seedlings with iron wire or nylon rope between bamboo poles. If the seedlings are sparse, you can tie a bamboo pole to the new bud of each seedling.

The second is the management of water, fertilizer and soil.

When the seedlings grow to 8 leaves, apply 15-20kg urea per mu, and apply it again after 15 days, generally three times. Topdressing outside the root is divided into two times, combined with spraying 0.5% urea in summer and 0.3% potassium dihydrogen phosphate in autumn, each spraying twice.

Before the grape seedlings germinate, they are usually watered once every 7 days. After the new shoots grow to 10-20cm, water them every half month. After the new shoots grow to 30-40 cm, water should be poured every 20 days, and it will not be watered if the soil moisture is good. If the grape seedlings don't leave the nursery before winter, water them for the winter. Water immediately after each topdressing. When the new buds grow to 7-8 leaves, the miscellaneous seedlings can be removed and uprooted. Different grape varieties should be marked with bamboo pieces and inserted between different varieties.

Planting management method of grape cutting seedlings

The survival rate of grape green branch cutting is high, and strengthening management can reach more than 85%. Therefore, cutting seedlings with green branches is a good method for rapid propagation of grape seedlings.

1. The seedbed is prepared to choose the land with good soil quality and high fertility as the nursery land, carefully arrange it, build a small border with a width of 1.2 meters, and drain open ditches on all sides.

2. Cutting collection: from May to July, select well-developed green branches and cut them into 20-25 cm long branches; Keep 2 leaves in the upper part, and remove the leaves from the rest, leaving the petiole. After cutting, soak the branches 1-2 hours with clear water to make them fully absorb water.

3. Dip branches with 100 mg/L NAA before cutting, and then press 30? Insert the branches in the same direction at a distance of 25 cm, two thirds of them are buried in the soil, and one third is exposed at the upper end. Immediately after insertion, pour water.

4. Manage immediately after inserting, put a sunshade on the border, and it takes about 30 days for the cuttings to take root and sprout. After germination, remove the sunshade, leaving only 1 strong buds for the surviving branches, and remove the core and secondary branches as appropriate. Before rooting and sprouting, keep the soil moisture sufficient and pay attention to pest control.

Grape planting method

Grapes are generally cultivated by inserting strings. In winter, cut a branch from an adult tree, put it in the soil, water it and cover it with plastic film.

The development period of grapevines is two to three years, and usually it will bear fruit in the third year.

Grape is a perennial woody plant that germinates in spring and leaves in autumn. Generally, the fruit ripens in August -65438+ 10, and the grapes will grow rapidly after germination in spring. It is very important to blossom in May 4th. If there are many strong winds and rainy days, it is not conducive to grape flowering and affects grape quality.

The vines of grapes grow too long in May, so we have to tie the vines to iron wires or wooden poles with ropes or cloth strips, and the workload may be a bit heavy. At this time, we should fertilize the grapes and spray foliar fertilizer. Let the grapes thrive.

By the end of May, the grapes have grown out, but due to the climate and diseases and insect pests, the fruit should be sprayed with fruit medicine to prevent the fruit from falling off.

At the end of June, the grape fruit is getting bigger and bigger, so we should first thin the fruit, that is, remove excess particles, let other particles grow up step by step, and then spray fruit medicine and swelling agent.

In July, the grapes began to ripen slowly, so it is necessary to prevent the damage of diseases and pests such as gray mold and white rot to the fruits, and then spray drugs on them later to add color and sweetness.

The fruit is fully ripe in August and can be sold. However, in the meantime, to prevent fruit cracking, it is still necessary to spray drugs in moderation.
