Planting techniques of Peach trees in greenhouse

In recent years, because the cultivation techniques are simple, labor-saving and efficient, planting peach trees in greenhouse has become the first choice for many farmers. The following editor will explain the planting techniques of peach trees in the greenhouse.

First, choose a suitable greenhouse

The cultivation facilities of peach trees in greenhouse usually use plastic film solar greenhouse, also known as plastic greenhouse. According to the size of the tree and the expected time when the fruit is on the market, different plastic greenhouses are selected. if you want the fruit to mature at the end of March and the beginning of April, it is necessary to use the winter warm plastic greenhouse.

Second, choose the right peach variety

The cold requirement of the selected varieties should be low, that is, the accumulative low temperature time needed to meet the natural dormancy is short, and the cumulative low temperature time below 7.2 degrees Celsius is less than 850 hours. In addition, self-pollination should be selected as far as possible in greenhouse cultivation, with high seed setting rate, large fruit, good color, good quality and resistance to transportation.

III. Buckle shed management

There is a large investment in peach cultivation in greenhouse, so it is necessary to make full use of the characteristics of fast growth and early fruiting of young peach trees, strengthen management, realize planting in the same year, flower in the same year, buckle the shed in the same year, and bear fruit in the next spring.

1. Strengthen the management of young trees: after planting, set the stem at the place of 30ml / 40cm, usually leave 2 main branches per plant, and pick out the heart when the new shoot grows to 30cm, so as to promote the secondary shoot to increase the vegetative area.

2. Heart-picking: the new shoots in other parts should be picked repeatedly and the over-dense and upright shoots should be removed in time, and the new shoots with better angles should be stripped and reserved as auxiliary branches, and the biennial seedlings can also be planted directly.

3. Fertilization: from the end of April to the beginning of May, topdressing three times every 15 seconds for 20 days, urea 8 kg / mu, potassium dihydrogen phosphate 5 kg / mu, watering after fertilization, hoeing to increase temperature.

4. Buckle the shed time: when to buckle the greenhouse to increase temperature depends on whether the natural dormancy of the cultivated varieties has been completed or not. Generally, the varieties with low cold capacity need to buckle the shed early or late. The earlier you cover, the sooner you mature.

In order to ensure full and complete natural dormancy. It is safer to withhold the shed in the first and middle of December.

IV. Pest control

The main diseases and insect pests of peach trees in greenhouse are aphids, gray mold, bacterial perforation and so on.

V. Management after unveiling the shed

After the fruit was harvested and uncovered, the overdense branches such as prosperous overlapping shoots, upright shoots and cross shoots were removed.

Planting peach trees in greenhouse should be based on the principle of adjusting measures to local conditions and scientific management in order to obtain high yield.
