Methods and application of improving fruit setting rate, fruit quality and field yield of Eli No. 2

Abstract

The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for improving the fruit setting rate, fruit quality and field yield of Eli No. 2 and its application. With the assistance of auxiliary facilities composed of cement columns and mesh surfaces, the present invention provides an improved simplified tree shape and shaping method by adjusting the traditional tree shape and tree vigor, reducing branching levels, and reducing ineffective growth. and maintain a reasonable field yield to achieve a reasonable balance between biological yield and field economic yield. At the same time, combined with supporting measures such as fertilization and bagging, Eli No. 2 finally achieved more flowers, better flowers, more fruit and more fruits. Good fruit, to achieve the goal of high yield, stable yield, and improve fruit quality.

Description

technical field [0001] The invention belongs to the technical field of fruit tree cultivation, and in particular relates to a method for improving the fruit setting rate, fruit quality and field yield of Eli No. 2 and its application. Background technique [0002] Pear is the third largest fruit tree cultivated in my country except apple and citrus. It is one of the important fruit trees traditionally cultivated in my country and one of the most advantageous fruit trees. In 2017, the national pear cultivation area was 921,000 hectares, and the output was 16.41 million tons. [0003] There are many kinds of pears in my country, rich in variety resources, and a long history of cultivation. However, under the background of modern agriculture with increasing labor costs, rising prices of production materials, and rapid development of informatization and digitalization, there are still many problems to be solved urgently. Especially the supporting issues of "suitable land + sui...

Problems solved by technology

In order to solve the problem of the small number of flower buds in Erli No. 2, the traditional method adopts measures such as trunk girdling, main branch circumcision, throwing and shrinking, and tip twisting, which has poor effect and weakens the growth potential of the tree.

[0008] At the same time, in order to solve the problem of the low fruit setting rate of Eli No. 2, the traditional method is to increase the proportion of pollination trees from 4-5:1 to 2-3:1 when building the orchard. Bees, artificial pollination, and boron fertilizer spraying can increase the flower bud fruit setting rate and inflorescence fruit setting rate. Although the number of fruits in the later stage of fruit growth is large, the single fruit quality is small and the fruit quality is poor, resulting in pre-harvest fruit drop.

[0009] The difficulty of solving the above problems and defects is: (1) under the traditional evacuation layered condition, how to effectively inhibit the vegetative growth of Eli No. 2, balance the relationship between vegetative growth and reproductive growth of the tree body, and promote the growth of Eli No. 2. Flower formation and good flower formation; (2) traditional cultivation methods, how to form a stable and moderate fruiting branch group; (3) how to promote flower formation, increase fruit setting rate, weaken tree vegetative growth, scientific load of fruit→rational consumption of nutrition→nutrition Steady growth→excellent flower bud quality→high fruit setting rate→fruit scientific load, such a virtuous circle
