Early-fruiting and high-yield cultivation technique for sweet cherries in south

Abstract

Disclosed is an early-fruiting and high-yield cultivation technique for sweet cherries in the south. The technique is characterized in that manchu cherries more than ten years old in south mountain forests are directly dug from the mountain forests and are planted in an orchard, and sweet cherry cultivars suitable for growing in the south are grafted onto the manchu cherries. The technique includes the specific steps of (1) soil preparation and planting pit digging in the orchard, (2) digging of the manchu cherry as stocks, (3) planting of the manchu cherries, (4) grafting of the sweat cherries and (5) culture management. The abundant manchu cherries (or known as wild cherries belonging to Chinese cherries with the varieties of sweet cherries, sour cherries and Nanking cherries) in the south mountain forests are taken as resources for direct grafting of the sweet cherries, and the cultivation technique is simple and easy to operate while the grafted cherries grow fast and fruit early. Practice by applicants proves that the grafted cherries blossom and fruit with only three years, more than seven years of time is saved, the requirement for high-yield tree crowns can be met, high yield and good harvest are realized, and planting the sweet cherries in the south comes true.

Description

technical field [0001] The invention relates to the field of fruit cultivation, in particular, it provides an early-fruiting and high-yield cultivation technology for introducing sweet cherries to the south. Background technique [0002] European sweet cherry is also called big cherry. After being introduced to the south, the growth is weak and the fruit is late. It usually takes more than 10 years from planting seedlings to flowering and fruiting. As a result, there is no large-scale planting of sweet cherries in the south. The sweet cherries sold in the southern market are all transported from the north. The early ones were produced in greenhouses, which are expensive and have a bad taste. The market time for open field cultivation is late, and most of them will be after the end of May. If the south can be successfully cultivated in the open field, they can arrive earlier. It will be launched in late April, which not only reduces production costs, improves the quality of ...

As a result, there is no large-scale planting of sweet cherries in the south

The sweet cherries sold in the southern market are all transported from the north. The early ones were produced in greenhouses, which are expensive and have a bad taste. The market time for open field cultivation is late, and most of them will be after the end of May. If the south can be successfully cultivated in the open field, they can arrive earlier. It will be launched in late April, which not only reduces the production cost, improves the quality of cherries, and can be launched one month earlier than the northern open field cultivation, but also provides a way for southern fruit growers to get rich
