Method for improving fruit setting rate, fruit quality and field yield of Eli No. 2 pear and application thereof

Abstract

The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a method for improving fruit setting rate, fruit quality and field yield of Eli No. 2 pear and application thereof. The invention provides an improved simplified tree form and shaping method by adjusting a traditional tree form and tree vigor with assistance of an auxiliary facility consisting of acement column and a net surface, reduces branch grade, not only reduces ineffective growth, but also maintains reasonable field yield, realizes reasonable balance between biological yield and field economic yield, and finally realizes more flowers, good flowers and good fruits of Eli No. 2 pear by combining with supporting measures such as fertilization, bagging and the like, and achieves goals ofhigh yield, stable yield and improving 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 and stratification condition, how to effectively suppress the vegetative growth of Eli No. 2, balance the relationship between tree body vegetative growth and reproductive growth, 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
