Happy tree shaped advantages. This kind of tree has its own characteristics. Its crown structure is three main branches staggered and grow firmly with the trunk. The main branch extends straight and the crown forms quickly. As a result, the branch group directly grows on the main branch and is evenly distributed with a large crown. It is not empty, there are many branchlets without crowding, the whole tree has good light, which is conducive to the three-dimensional structure; therefore, it has a high yield and a long life in the full fruit period.
Trim the details. Peach trees can be trimmed from 15 days after February to February of the following year. The pruning method can adopt long-tip pruning, that is, the main branch is mainly used for pruning the fruiting branches, and no short cutting can be performed. For the treatment of the main branch extension, for the young tree, select 3 to 4 main branches with evenly distributed orientation. Any branch above 1/3 of the growing position must be firmly removed as a competitive branch; if there is space, it must be left. 2 to 3 cm dumplings. The extension of the main branch adopts uniaxial extension to avoid recurrence. The back branch is used to change the head and the zigzag extension pruning method is adopted.
For trees that have moved out of the fruiting area and have severe bald heads below, the method of thinning the large side branches on the main branch year by year should be adopted, and the peach canal should be gradually restored to restore fruiting ability, and the light should be opened to solve the problems that cause the orchard to deteriorate Orchard closed.
For various fruiting branches, specific principles should be grasped when pruning. The fruiting branch should be as close as possible to the main branch, that is, the fruiting axis should be short, so that the inside and outside are not left, and the fruiting part is prevented from moving outward. Results The medium and long fruit branches were the main choices, and the short fruit branches were no longer the main fruit. Although short fruit branches below 10 cm have high fruit setting rate, it is not easy to cultivate large fruit. The fruiting branches with a thickness of 30 to 50 cm and a thickness of 0.4 to 0.6 cm are reliable and of good quality. After pruning, the amount of branches left to control is about 8,000, which can fully meet the production requirements.
For branches with a thickness of less than 5 cm, scissors should be used for pruning, especially the use of large scissors to ensure that the cutting saw is smooth. If it is more than 5 cm, use a fast saw to ensure a smooth cutting edge. After trimming, apply a wound healing agent to the cutting saw's mouth of more than 2 cm to avoid the flow of glue and rot, and use the wound to heal.

Ventilation is one of the most important components in a successful greenhouse.
If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
