Abstract

The invention discloses a method for fruiting and flowering axillary buds of carya illinoensis saplings, which belongs to the technical field of fruit tree cultivation and comprises the steps of selecting healthy and strong seedlings for field planting, managing the current year and the second year of field planting, regulating and controlling the tree vigor of the saplings and fruiting the axillary buds of the saplings. The technology of the invention utilizes paclobutrazol to control the vegetative growth of trees and promote the reproductive growth, and the matching bud carving measures are used to promote the axillary buds to blossom and bear fruits, thereby solving the problems of less early bearing and low yield caused by the fact that the carya illinoensis saplings only bear fruits by the terminal buds and 1-3 buds below the terminal buds, and promoting the carya illinoensis saplings to bear fruits in advance, and the bearing time is 1-2 years ahead of time.

Description

Method for fruiting apocarya young tree by axillary bud formation
Technical Field
The invention belongs to the technical field of fruit tree cultivation, and particularly relates to a technique for axillary bud flowering of a carya illinoensis sapling.
Background
Carya illinoensis K.Koch, Changshan walnut and American Carya illinoensis are deciduous trees of Carya genus of Juglandaceae family. The nutlet is rich in nutrition and high in health care value, and researches show that the long-term eating of the peclet can obviously improve the content of gamma tocopherol in blood, and has the effects of preventing aging, strengthening intestines and stomach and preventing prostate cancer. Walnut kernel is also rich in trace elements necessary for human body, such as phosphorus, zinc, iron, calcium, magnesium, manganese, copper, selenium, and the like, and nutrients, such as vitamins E, B and 32 and coenzyme Q10, and is called super food in the 21 st century and astronauts food.
In China, the carya illinoensis is introduced at the beginning of the 20 th century at the end of the 19 th century, seeds or seedlings are mainly used and planted in schools, churches and private residences on the ports of general merchants, and the planting benefit is seriously influenced because the fruiting of the seedling trees begins in 10-12 years. In recent 10 years, under the efforts of scientific researchers, the grafting technology is broken through, the fruit starting time is shortened to 4-5 years, and the planting scale of suitable growing areas such as Yunnan, Jiangsu, Zhejiang and Anhui in China is increased sharply. The carya illinoensis has the habit of fruiting terminal buds and 1-3 axillary buds below the terminal buds, the fruiting mother branches are more than medium and short branches, the growth potential of the young trees is strong, most of the formed branches are long branches, the current situations of less flower buds, low fruit setting rate and low yield of the young trees are caused, and the development of the industry is limited.
Disclosure of Invention
The invention aims to overcome the defects of the prior cultivation technology and provide a method for promoting the young trees to fruit early.
The inventor of the invention discovers in research that by adopting the technology, the planting of the carya illinoensis saplings starts from 3 years, 1-2 years ahead of the conventional planting is realized, and the early yield is ensured.
Accordingly, in order to achieve the above objects, the present invention provides a pecan sapling axillary bud fruiting technique, comprising: nursery stock planting, sapling management, tree vigor regulation and control, and axillary bud flowering.
Preferably, the conditions for seedling planting comprise: the selected nursery stock is a fine variety which is identified or approved by the national or provincial governing department; the specification of the nursery stock is that the main root is more than 35cm, the number of the first-stage lateral roots is more than 40, the main root is not curled and wound, the height of the plant is more than 1m, and the ground diameter is more than 1.2 cm.
Preferably, the management of the saplings comprises that after planting, 80cm of nursery stocks are fixed to be dry, the water management is mainly used for planting in the current year, the soil is kept in a wet state all the time, the new shoots with the growth amount reaching 60cm are subjected to pinching in 8 months, and 3-5 lateral branches are formed at the end of the growing season; applying 30 jin of decomposed organic fertilizer to each tree at the bottom of 2 months in the next year, and applying 0.5 jin of compound fertilizer to each tree in 4 months and 9 months respectively; the side branches reach 40cm pinching.
Preferably, the regulation and control of the tree vigor of the saplings comprises the steps of applying 10mg of paclobutrazol to the trunk cross-sectional area (measured at a position 30cm away from the ground) of each square centimeter in 7 months of the second year of field planting, and adding 30 jin of water to each tree after dissolution to irrigate roots.
Preferably, the axillary bud flowering of the saplings comprises the steps of bud carving in the third year after planting, selecting side branch full buds with the thickness of more than 1cm and carving wounds: before germination, a small hacksaw blade is used for cutting at the position of promoting the growth of the short branch and 3mm above the bud, the cortex is damaged, the small hacksaw blade does not go deep into the xylem, more than 90 percent of carved buds can form the medium short branch, and the medium short branch blossoms and fruits in the same year.
The invention has the beneficial effects that:
1. by adopting the method, the axillary buds of the apocarya young trees can be fruited by flower formation, and the problem of few bearing branches caused by the fruiting of the apocarya with the terminal buds and 1-3 buds below the terminal buds is solved.
2. By adopting the method, the carya illinoensis can bear fruits in the 3 rd year of field planting, and the fruit bearing is 1-2 years earlier than that in the current 4-5 years.
3. By adopting the method, the average fruit bearing of the carya illinoensis per plant in the 3 rd year of field planting is 152, the yield per mu is 38.4 jin, and the early yield is improved.
The method can be widely used for the high-yield cultivation of the early-bearing carya illinoensis.
Additional features and advantages of the invention will be set forth in the detailed description which follows.
Detailed Description
The following examples further illustrate the invention but are not intended to limit the invention thereto.
The modern agricultural development ecological garden is specifically implemented in Sihong county Hui.
1. Planting the nursery stock: in 3 months in 2010, 5 mu of carya illinoensis is fixedly planted, the plant spacing is 4m, and the row spacing is 10m, and the total number of the carya illinoensis is 80. The variety is Wiston, the height of the nursery stock is about 1.2m, the ground diameter is more than 1.2cm, the main root is 35-40 cm, no curling and winding are generated, and the number of the primary side roots is 45-55; after the planting, drying the seedlings by 80cm, and cutting the openings to coat vaseline.
