Breeding and cultivation method for plum variety

Abstract

The invention provides a breeding and cultivation method for a plum variety, and relates to the field of cultivation of fruit trees. The invention solves the problems of general cold resistance, phytotoxicity resistance, disease resistance and pest resistance and serious tree aging phenomenon in the cultivation process of a plum tree. The breeding and cultivation method provided by the invention comprises the following steps: land selection, land preparation, and application of a soil conditioner after soil preparation; scientific fertilizer application, which comprises topdressing before flowering, topdressing after flowering, topdressing in a fruit swelling period and a flower bud differentiation period, and topdressing in a later fruit growth period; transplanting; pruning management, which comprises pruning management in a sapling period, a full bearing period and an aging period; disease and pest control, which comprises plum red spot disease control, plum gummosis control, Grapholitha funebrana Treitscheke control, aphid control and Tetranychus cinnabarinus control; real-time harvesting; etc. The plum tree cultivated by using the method provided by the invention has extremelystrong cold resistance, red spot disease resistance and phytotoxicity resistance, is free of total harvesting failure in the case of occurrence of phytotoxicity, and is resistant to cold spell in later spring; and a Jisheng plum variety has the advantages of hard branches, abundant fruiting, few branch breaking phenomenon, and no tree aging phenomenon for a tree in a life span of 30 years.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a breeding and cultivation method of a plum variety. Background technique [0002] Plum is a plant of the genus Prunus in the Rosaceae, also known as Jiaqingzi, Bulin, plum, Yuhuang plum, and mountain plum. Its fruit matures between June and August. It is plump and round, exquisite and translucent, beautiful in shape and sweet in taste. It is one of people's favorite fruits. Widely cultivated all over the world. Plums are sour, and the nutrition of plums is slightly lower than that of peaches, containing sugar, trace protein, fat, carotene, vitamins (B1, B2, C), niacin, calcium, phosphorus, iron, asparagine, glutamine, serine, Glycine, proline, threonine, alanine and other ingredients. The edible part of every 100 grams of plums contains 116.2-221.9 kilojoules of energy, 8.8 grams of sugar, 0.6 grams of protein, 0.25 grams of fat, 100-360 micrograms of vitamin A...

Problems solved by technology

[0003] In the current cultivation process of plums, overwintering in winter is fatal to the cultivation of fruit trees. At the same time, the late-maturing varieties of dry-core plums are single, with general cold resistance, drug resistance, disease resistance, and insect resistance, and the tree body is aging. serious
