[0003] However, this pruning method leaves less branches and a large amount of pruning in winter. At present, there is no suitable machine to replace manual pruning, which leads to high labor intensity and high cost for fruit farmers;

Embodiment 1

[0015] Variety: Baojiahong, peach, mature period in mid-to-late July, tree age: 9-11 years old, planted in Nantai Yu Village, Shunping County, Hebei Province, using nutrient dispersion and slow-release pruning method, when the fruiting branches of peach trees are selected in winter The annual fruiting branches are not cut short. Except for the backbone branches and the branches of the fruiting branch groups larger than 30 cm, the long fruiting branches are left, and the other parts are mainly left with medium and short fruiting branches. The number of branches left after pruning is 23,500 to 25,000 / mu.

[0016] After pruning, the ratio of various types of branches to the total amount of remaining branches is: 3.2% to 4.3% for super long branches >60 cm, 18.5% to 22.7% for long branches of 30 to 60 cm, 32.5% to 34.9% for medium branches of 15 to 30 cm, 5 27.8% to 30.0% of short branches less than 15 cm, 18.0 to 20.0% of bouquet-like branches less than 5 cm.

Embodiment 2

[0020] Variety: Cangfang early-growing, hairy peach, mature in mid-July, tree age: 13-15 years old, planted in Zhoulonghua Village, Shenzhou City, Hebei Province, using the method of dispersing nutrients and pruning slowly, and pruning peach trees in winter when fruiting branches are selected. The annual fruiting branches are not cut short. Except for the backbone branches and the branches of the fruiting branch groups larger than 30 cm, the long fruiting branches are left, and the other parts are mainly short and medium fruiting branches. The number of branches left after pruning is 21,900 to 23,200 / mu.

[0021] After pruning, the ratio of various types of branches to the total amount of remaining branches is: 3.0% to 3.5% for super long branches > 60 cm, 18.9 to 24.5% for long branches of 30 to 60 cm, 29.5% to 32.9% for middle branches of 15 to 30 cm, and 29.5% to 32.9% for middle branches of 5 to 30 cm. 27.4-29.3% of 15 cm short branches, 15.9%-16.0% of <5 cm bouquet-like...

Abstract

The invention discloses a nutrient dispersion and slow-release pruning method for mature peach trees. The method does not short-cut the annual fruiting branches when the winter fruiting branches of the mature peach trees are selected, and removes the backbone branches and fruiting branches larger than 30 centimeters. Except for the long fruiting branches at the top of the branches, the other parts are mainly medium and short fruiting branches. The amount of branches left after pruning is 20,000 to 25,000 / mu. The present invention is applied to the pruning of peach trees, which can realize the dispersal of nutrition, control the vigorous growth, reduce the amount of pruning in winter and summer, and reduce the manpower for pruning by more than 40%.

Description

technical field [0001] The invention relates to the technical field of fruit tree planting, in particular to a nutrient dispersion and slow-release pruning method for mature peach trees. Background technique [0002] In recent years, the pruning method of fruiting branches in peach production is mainly long shoot pruning. Long-shoot pruning is a method of treating annual fruiting branches without cutting them short, selecting long fruiting branches for fruiting, and removing all other fruiting branches. When pruning long shoots, the branch retention density is generally 1 long fruiting branch for every 15-20 cm on the backbone branches and large fruiting branch groups. The distance between the same side fruiting branches is generally more than 40 cm. The amount of preserved branches in the whole tree is traditional. 50% to 60% of the short-cut pruning method. The length of the resulting branch retained by long shoot pruning is 40-60 cm. The medium and long branches shorte...
