Dwarfing sweet cherry greenhouse potting method

Technical Field

The invention belongs to the technical field of fruit planting, and particularly relates to a dwarfing sweet cherry greenhouse potting method.

Background

The sweet cherry has the advantages of early fruit bearing, quick response, high benefit, greenness and safety, so the sweet cherry becomes the most important tree species for facility fruit tree cultivation, sightseeing picking and leisure travel. The cultivation area of the whole country is about 300 ten thousand mu, which occupies the first place in the world. The planting area is also expanded from the past Bohai Bay area to inland, and is further developed to 25 province and city autonomous regions such as the coastal regions in south, the high altitude regions in the west, the alpine regions in the northeast and the like.

The fruit tree potted plant can purify air, green the environment and cultivate sentiment. However, the traditional fruit tree potting is mostly limited to pomegranate, grape, orange, apple, peach and the like, and the sweet cherry is rarely used, one of the main reasons is that the sweet cherry has a big tree body and is difficult to control the tree body; secondly, the sweet cherry belongs to a cross-pollinated fruit tree, and one plant is matched with at least two varieties in the potting process. In recent years, large cherry potting is gradually stepping into balconies and courtyards of thousands of households along with improvement of potting technology and application of dwarfing stocks. Like other fruit tree potted plants, the large cherry potted plant can not only enjoy beautiful scenery with full flowers and branches and rich fruits, but also taste delicious fruits after enjoying. However, the best method for potting sweet cherries at present is to graft 2-3 varieties capable of pollinating mutually in each pot, such as red light, Meizao, Raney, Jiahong, Sammituo and the like, and the stock is an arbor stock in multiple choices.

Greenhouse potted cherries have many advantages. Usually, after field planting of cherries in an orchard, the cherries can bloom and bear fruits after 5-6 years, the potted sweet cherries can be used for field planting for 1-2 years at the fastest speed, and a certain yield is achieved in the third year, so that early fruiting and early high yield are realized; the potted sweet cherry has reduced tree height due to root limitation, and is beneficial to fruit picking; the potted sweet cherry can also be moved to a greenhouse or cultivated indoors, so that the sweet cherry can be listed in the market early, and the income is increased.

Although the potted cherry is cultivated in a greenhouse, the aims of early fruiting and early high yield can be achieved. There are still many problems that need to be further studied and solved. For example, the tree body is difficult to control, the fruit bearing is late, the fruit setting rate is low, the tree shape is not standard, and the like, so that the large-area application and the rapid development of the potted sweet cherry are severely restricted.

Results of the experiment

The treatments in examples 1 and 2, bagging, and self-flower set rate were measured, specifically as shown in fig. 1, for control sago flowering as shown in fig. 2, and for rabins flowering as shown in fig. 3. The results of the two-year-round selfing rate survey are shown in table 1:

TABLE 1 survey of self-fruitfulness after grafting of different scions two consecutive years

Scion	Self-flower bearing rate
		Labin' s	30％-35％
HS08-219	35.4％～41％
		Changhua purple jade	45.6％～55.8％
Sami food	0％

As can be seen from the above table, Labin, HS219 and Changhua purple jade have good self-flower-bearing effect, only one kind of scion needs to be grafted during grafting, and when Sami comes off, scions which can pollinate mutually need to be grafted simultaneously.

The treatments in examples 1 and 2, both in late pot 10 months, were moved into a freezer and the time schedules after grafting of the various scions (where the control samader was 0 due to self-flower setting percentage and simultaneously grafted with pioneers for cross-pollination) were counted as shown in table 2:

TABLE 2 flowering and fruiting times after different scions grafting

Scion	Time to go out of refrigeration storage	Sprouting	Flower blooming	Ripening of fruit
					Labin' s	11.10	12.10	12.20	Next year 2.20
HS219	11.15	12.15	12.25	Next year 2.25
					Changhua purple jade	11.20	12.20	12.30	Next year 3.3
Sami food	11.25	12.25	Next year 1.5	Next year 3.10

As can be seen from Table 2, the fruit ripening period of the Labinis with less cold demand is earlier (10-20 days) than that of other varieties, and the market price is much higher. A photograph of the Labins results is shown in FIG. 4, and a photograph of the prolific product is shown in FIG. 5.
