Problems solved by technology

When cultivating large cherries in low-latitude and high-altitude areas, due to the influence of monsoon climate, the flowering period is easily affected by drought, low temperature and frost damage, and the fruit setting rate is often extremely low, less than 1%, without any economic benefits.
In addition, the existing technology for improving the fruit setting rate of large cherries mainly has the following disadvantages: (1) release bees during the flowering period, but when this method is used in low-latitude and high-altitude areas, due to the hot and cold temperatures in spring, the bees have poor activity and It is easily affected by the spraying of pesticides, and its effect is easily affected. The yield of large cherries varies greatly between years; (3) Irrigation before flowering, although it can delay the germination period and improve soil moisture, but it also reduces the ground temperature, which affects the normal transmission zone of water and nutrients in the tree body. It has a certain impact, which affects the yield and fruit quality of large cherries; (4) The use of plastic film mulching, although it can have a certain effect on soil moisture and weed control, has poor permeability and unstable soil temperature

Embodiment 1

[0017] Ridge is planted on the row that has big cherry tree, and the height of this ridge is 30cm, and width is 120cm; When in autumn, dig the ground ridge close to the tree root and apply organic fertilizer and bury it, then water, and use the same amount of ridge width again. Cover with matching horticultural ground cloth; add micro-spraying facilities on the upper part of the canopy, and start the micro-spraying facilities when the temperature is ≥ 22°C during the period from pre-flowering to young fruit stage in spring, and spray to cool down to 18°C. Among them, apply 6kg of organic fertilizer and pour 7kg of water to each tree whose age is 5 to 8 years; apply 9kg of organic fertilizer and pour 10kg of water to each tree whose age is more than 9 years. After testing, the fruit setting rate was 35%.

Embodiment 2

[0019] Ridge is planted on the row that has big cherry tree, and the height of this ridge is 35cm, and width is 130cm; When in autumn, dig the ground ridge near the tree root and apply organic fertilizer and bury it, water then, and use the same amount of ridge width again. Cover with matching horticultural ground cloth; add micro-spraying facilities on the upper part of the canopy. During the period from pre-flowering to young fruit stage in spring, when the temperature is ≥ 22°C, start the micro-spraying facilities and spray to cool down to 20°C. Among them, apply 5kg of organic fertilizer and pour 6kg of water to each tree whose age is 5 to 8 years; apply 10kg of organic fertilizer and pour 10kg of water to each tree whose age is more than 9 years. After testing, the fruit setting rate was 33%.

Embodiment 3

[0021] Ridge is planted on the row that has big cherry tree, and the height of this ridge is 35cm, and width is 150cm; When in autumn, dig the ground ridge near tree root and apply organic fertilizer and bury it, water then, and use the same amount of ridge width again. Cover with matching horticultural ground cloth; add micro-spraying facilities on the upper part of the canopy, and start the micro-spraying facilities when the temperature is ≥ 22°C during the period from pre-flowering to young fruit stage in spring, and spray to cool down to 17°C. Among them, apply 6kg of organic fertilizer and pour 5kg of water to each tree whose age is 5 to 8 years; apply 9kg of organic fertilizer and pour 8kg of water to each tree whose age is more than 9 years. After testing, the fruit setting rate was 36%.

Abstract

The invention relates to a cultivation method for achieving large cherry high yield on low-latitude and high-altitude areas, and belongs to the technical field of large cherry artificial cultivation. The method includes the following steps: a, ridging, wherein the ridging is performed on lines where large cherry trees are planted, the height of ridges is 15-45cm, and the width of the ridges is 100-180cm; b, fertilizing and film mulching, wherein alleys close to tree roots are excavated for fertilizing and buried after being fertilized in autumn, irrigating is performed, and then mulching is performed with gardening ground fabric; and c, irrigating in a sprinkling manner, wherein micro jetting facilities are additionally arranged on the upper portions of tree crowns, the micro jetting facilities are started when the temperature is larger than or equal to 22 DEG C from the pre-bloom period to the fruitlet period in spring, and mist cooling is performed to lower the temperature to be 15-21 DEG C. The cultivation method for achieving the large cherry high yield on the low-latitude and high-altitude areas has the advantages that the yield of large cherries can be improved on the low-latitude and high-altitude areas, and therefore economic benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of artificial cultivation of large cherries, and in particular relates to a cultivation method for increasing the high yield of large cherries in low-latitude and high-altitude areas. Background technique [0002] Big cherry is a fruit tree with high economic benefits. It is the earliest fruit tree species of deciduous fruit trees in northern China after Chinese cherry, so it is known as "the first branch of spring country". It is known as a treasure among fruits for its bright color, plump flesh, rich nutrition, and delicious aroma. It is favored by consumers in the fruit market. When cultivating large cherries in low-latitude and high-altitude areas, due to the influence of monsoon climate, the flowering period is easily affected by drought, low temperature and frost damage, and the fruit setting rate is often extremely low, less than 1%, without any economic benefits. In addition, the existing technology...
