Planting method of potted grape

Potted grape planting method, potted grape is actually the general name of container grape cultivation. Those who use pots, boxes, buckets and planting troughs to cultivate grapes can be called potted grapes. The potted grapes bear fruit early. If the cultivation is managed properly, they can bear fruit in two years. Each pot grape can produce fruit 1-3kg, and many can reach 4-5kg. The following editor introduces the potted grape planting method.

Preparation of basin soil

1. Container selection: available containers include tile pots, pottery pots, purple sand pots, wooden pots, plastic flowerpots, etc., which can be selected according to the conditions. Potted grapes can use containers with a pot mouth diameter of about 20-25cm in the first year, and 30-40cm containers with a pot mouth diameter after 3 years. It can be determined according to production capacity and site space.

2. basin soil requirements: loam which is loose, fertile and rich in organic matter and calcium. Local materials can also be used according to the specific conditions of various places, and culture materials with a wide range of sources, low cost, no diseases and insects and no pollution can be selected. The commonly used materials are rotten leaf soil, peat soil, pastoral soil, sand and gravel, bone meal, expanded chicken manure and so on.

3. Preparation of basin soil: the commonly used formulations are 4 parts of ① rotten leaf soil, 3 parts of garden soil, 3 parts of coarse sand and 0.5 parts of bone powder. 7 samples of ② pastoral soil, 2 samples of coarse sand (or slag), 1 part of expanded chicken manure and 0.5 part of bone meal.

4. Disinfection of basin soil: after mixing the basin soil, spray it evenly with 0.1% formalin solution (500 ml per cubic meter of basin soil). Then seal it with plastic film, fumigate for one day and night, remove the film, dry it for 4 days, and then put it into a basin.

Variety selection

The grape varieties available for pot cultivation are Jufeng, Jingya, Jingchao, Idou Jin, Heolin, Jingyu, Fenghuang 51, Tilawa, 8611, 8612, Zizhenxiang, American Heidi and so on.

Upper basin and soil exchange

After the flowerpot is selected, it is best to soak it in 1% bleach water for 5 minutes, take it out and dry it, and then load it into the sterilized culture soil. Seedlings used in potted grapes can be cut directly in flowerpots and cultivated into seedlings.

When cutting, it is best to insert 2 cuttings in each pot for selection and retention, and often keep the soil in the basin moist. Grape plants of 1-3 years old can also be transplanted with soil masses before sprouting.

When transplanting, the branches of the plant should be re-cut, generally leaving 1 Mel 3 strong vines. Transplanting that year, the focus is to restore the tree potential, cultivate the tree shape, lay a good foundation, do not bear fruit first.

After the plant grew in the basin for 2 years, the original container space could not meet the requirements of root growth and development, and the nutrients of the basin soil gradually decreased. Therefore, the container needs to be changed from small to large or the basin soil needs to be replaced. This work is generally carried out before the dormancy period is about to end and before the growth begins. When changing the basin or soil, part of the withered roots should be cut off and watered immediately after the change, so as to facilitate the restoration of plant growth.

Shaping and pruning

1. Single rod shape

Suitable for small and medium-sized potted plants, when planted, stand a bamboo pole or No. 8 iron wire in the middle of the pot, about 1m high. After the new shoots germinated, a strong shoot was selected as the main vine, which was tied to the bamboo pole and picked out when it grew to 80-90cm. After that, except for the top one, the other two leaves were left to pick the heart repeatedly.

The branches that mature well during winter pruning can be cut to retain 50cm. After germination in the second year, 5 robust shoots were left on the main vine, and the rest of the buds should be erased in time. During winter pruning, 3 buds of each new shoot were left to be pruned as fruit mother branches. After sprouting in the third year, two new shoots were left for each fruiting mother branch, and then cut every year.

2. Sector shape

In the winter of the same year, the pruning of new shoots above 60cm was reserved as the trunk, and in the next year, one new shoot was tilted and tied every other 10-15cm, and in winter shearing, it was a fruiting mother branch with three buds, and in the third year, two fruiting branches were left on each fruiting mother branch. The new shoots and fruit ears were evenly distributed in one plane, and the flowerpot and fan were enlarged with the increase of tree body.

Fertilizer and water management

1. Fertilization

The principle of fertilizer application for potted grapes is to apply less frequently. The pot seedlings that have not yet borne fruit generally start from the seedling height of about 20cm (that is, 6 Mel 7 leaves), and apply cake fertilizer and water once every 10 days until the end of September.

For the fruitful potted grapes, in order to meet the requirements of fruit development, it is best to apply them every 5 days, and then apply them according to potted seedlings after fruit harvest, and pay attention to watering immediately after each application of liquid fertilizer.

Potted grapes can also be foliar sprayed by spraying 0.1% Mel 0.3% urea solution 2Mel 3 times in the early growth stage of potted grapes. Starting from the fruit expansion period, 0.3% KH 2H 2PO 4 solution can be sprayed every 7 times every 10 days.

2. Watering

When watering, the water temperature had better be close to the basin soil temperature, and it is appropriate to water before 10:00 or after 4 p.m., the water quality should be good, and the watering times should depend on the season. Generally, the temperature in early spring is low, and it can be watered every 3 days. As the air temperature increases, evaporation increases, it can be watered once every 2 days. After the temperature gradually decreases in autumn, the watering times gradually become less, and the basin soil is moist.
