Embodiment 1

[0029] From 2007 to 2009, a total of 10 acres of demonstration orchard apple saplings were planted in Fengxiang Experimental Station of the national apple industry system and farmer orchards to apply the plastic pruning technology of the present invention to promote the formation of flower buds of "Fuji" saplings, and evenly randomly selected 72 trees (3 Each plot has 24), each plot establishes three processes, and each handles trunk and drawn branch opening angle to be 70 °, 90 ° and 110 ° respectively, and every kind of processing is 8 saplings.

[0030] The area has a longitude of 107.39°, a latitude of 34.53°, and an altitude of 850m. The annual average temperature is 12.0-12.5°C, the precipitation is 601mm, the frost-free period is 209 days, and the temperature difference between day and night is large. In this experiment, the "Fuji" apple saplings were planted at a distance of 2.0×3.5m. The base stock was Xifu crabapple, and the middle stock was M26.

[0031] After the m...

Embodiment 2

[0048] From 2003 to 2006, the plastic pruning technology of the present invention was applied to 25 acres of demonstration apple saplings in the orchard of Baoji Agricultural Science and Technology Fruit Industry Expert Compound to promote the formation of flower buds of "Fuji" saplings, and 25 trees were evenly randomly selected (set 5) processing, each processing 5 trees), each processing main trunk and drawn branch opening angles are 55°, 70°, 90°, 110° and 120° respectively, and each processing is 5 saplings.

[0049] After the material apple trees selected for the experiment were formed, comparative analysis and research was carried out on the nutrient content in the leaves and branches of "Fuji" apple saplings, the length and number of new shoots from 2006 to 2007, in order to evaluate and compare the plasticity. Pruning techniques promote flowering effect of "Fuji" apple saplings.

[0050] The "Fuji" apple saplings in this experiment are planted at a distance of 2.5m×4....

Embodiment 3

[0067] From 2009 to 2011, a total of 15 acres of demonstration orchard apple saplings were planted in Fengxiang Experimental Station of the national apple industry system to apply the plastic pruning technology of the present invention to promote the formation of flower buds of "Fuji" saplings, and evenly randomly select 54 trees (3 District, each district has 18 trees), each district establishes three treatments, and each treatment trunk and drawn branch opening angle are respectively 70 °, 90 ° and 110 °, and every kind of treatment is 6 saplings.

[0068] After the apple trees selected for the test were formed, sampling and analysis were carried out from 2011 to 2012 (the content of the measurement was the soluble sugar, starch, total nitrogen content and carbon content of the short branch terminal buds of "Fuji" apple saplings in different time periods. Nitrogen ratio for comparative analysis and research) to evaluate and compare the effects of the shaping and pruning techn...

Abstract

The invention discloses a shaping and trimming method for promoting flower bud formation of Fuji apple saplings. The shaping and trimming method includes steps of (1), fixing a sapling, performing steps (2) to (4) every year before a tree shape of the sapling is formed; (2), drawing a bough on a trunk of the sapling so that an opening angle between the trunk and the drawn bough of the sapling ranges from 105 degrees to 115 degrees; (3) trimming same-year spindling branches on the drawn bough and reserving same-year normally growing branches on two sides of the drawn bough; and (4), when the number of boughs on the trunk of the sapling reaches 9-11, 8-10 and 7-9 on the lower portion, the middle portion and the upper portion of the body of the sapling and the total number of the boughs reaches 24-30, trimming excessive boughs growing on the trunk. By drawing the bough downwardly and arranging the angle between the bough and the trunk and distribution positions of the boughs, ventilation and light-permeable conditions are improved, bud sprouts on the branches and growing of a great quantity of short branches and short fruiting branches are promoted, and flower bud formation is remarkably promoted.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a shaping and pruning method for promoting flower bud formation of young Fuji apple trees in the Loess Plateau region. Background technique [0002] my country is one of the major producers of apples in the world. In 2010, the country's apple planting area was 30.84 million mu, with an output of 32 million tons, accounting for 51.6% of the world's output of 61.946 million tons, ranking first in the world. Apple industry plays an important role in regional economic development and farmers' income increase. "Fuji" apple variety is loved by everyone for its excellent quality and taste, and "Fuji" apple variety has become the apple variety with the largest planting area in my country (Zhai Heng, Zhao Zhengyang, Wang Zhiqiang, etc. Analysis of the development trend of the world's apple industry[J] .Journal of Fruit Trees, 2005, 22 (1): 44-50), its planting a...
