Peach tree is an important economic forest tree species in China. Close planting and increasing early yield of peach trees are the development trends of peach tree cultivation. Peach trees are mostly planted in trunk shape, but the existing problems are that after several years of cultivation, trunk-shaped peach trees are prone to the phenomenon of "strong on the top and weak on the bottom" and "big on the bottom and small on the bottom", resulting in large upper fruits, bright colors, good quality, few lower fruits, poor color and quality, and low high-quality fruit rate, which affects the economic benefits of peach tree planting. The urgent task is to improve the "trunk-shaped" tree shape of peach trees, and overcome the phenomena of "strong on the top and weak on the bottom" and "big on the bottom and small on the top", so that the branches and fruits of peach trees can see the sun and bear more high-quality fruits and commercial fruits.

Although there are many technical standards for peach trees in China, most of them are technical standards for comprehensive management of peach trees, and a few technical standards for shaping and pruning peach trees are also technical standards for shaping and pruning all kinds of trees, but there is no technical standard for peach trees. The "pagoda-shaped" pruning technology of peach trees has matured, and it is urgent to popularize and apply it in production to improve the quality of peach trees. Therefore, the Technical Specification for Pagoda-shaped Pruning of Peach Trees (DB 4 105/T 136-2020) was promulgated. [3]

Technical Specification for Pagoda Pruning of Peach Trees (DB 4 105/T 136-2020) was put forward by the Fruit Tree Association of Neihuang County. [3]

In the process of compiling, the team summarized the successful experience of peach tree "pagoda-shaped" shaping and pruning and related scientific research achievements, solicited the opinions of relevant units and individuals, repeatedly discussed, revised and supplemented the contents of peach tree "pagoda-shaped" shaping and pruning technology, and finally put forward the Technical Specification for Peach Tree "pagoda-shaped" shaping and pruning "(DB 4105/T/KLOC- [3]

65438+20201From October 2nd to February 2nd, Anyang Municipal Market Supervision Administration put forward the draft of the standard for soliciting opinions and the compilation instructions, and publicly solicited opinions and suggestions from the society on the website of Anyang Municipal Market Supervision Administration.

On April 26th, 2020, People's Republic of China (PRC) and Anyang Municipal Market Supervision Bureau issued the Technical Specification for Shaping and Pruning Pagoda Peach Trees (DB 4 105/T 136-2020). [ 1]

On May 26th, 2020, the Technical Specification for Pruning Peach Pagoda (DB 4 105/T 136-2020) was implemented. [ 1]
