Embodiment 1

[0023] Example 1 Fruit-bearing test of Wichita pecans

[0024] 1Materials and methods

[0025] 1.1 Materials The test material was 20 pecan seeds. After the seeds germinated in the spring of 2012, 10 germinated seeds were transplanted to a small root control device and cultivated and managed according to the patented method. Wichita variety scion grafting was adopted, and after two root control container cultivations (hereinafter referred to as "the patent method "), planted in Changshan Ecological Agriculture Park, Shili Changshan, Dantu District, Zhenjiang City, Jiangsu Province. The remaining 10 are cultivated in a field nursery, and when they reach the grafting thickness, they will also be grafted with Wichita scion, and then planted on the same plot in the winter of the year after grafting (hereinafter referred to as "conventional method"). This patent law is the same.

After the seeds germinated in the spring of 2012, 10 germinated seeds were transplanted to a small root control device and cultivated and managed according to the patented method. The Ponie variety scion grafting was used, after two root control container cultivations (hereinafter referred to as "the patent method") ), planted in the Shili Changshan Ecological Agriculture Park, Dantu District, Zhenjiang City, Jiangsu Province. The remaining 10 are cultivated in a field nursery. When they reach the grafting thickness, they will also be grafted with Pawnee scion, and then planted on the same plot in the winter after grafting (hereinafter referred to as "conventional method").

Abstract

The invention relates to a method for promoting early fruiting of pecans. The method comprises the following steps: carrying out lamination and germination acceleration on the pecan seeds; when the bud seedlings germinate to a plurality of new leaves, cutting the root of the bud seedling and dipping the bud seedling into a rooting solution, and then transplanting the bud seedling to a small root control device for rooting; when the nursery stocks grow to a proper roughness, carrying out square bud grafting; in the same year when the bud grafting is carried out, moving the variety seedlings outfrom the small root control device to prune the root after the fallen leaves are fallen, dipping the seedling into the rooting solution and transplanting the seedling to a large root control device for cultivation; according to different periods of bud grafting growth, sequentially spraying a growth promoting liquid for the first time, carrying out pinching for the first time, spraying a growth promoting liquid for the second time, carrying out pinching for the second time; in the same year, after leaves fall, trimming the root again, dipping the root into the rooting solution and transplanting the seedling to an orchard for field planting. According to the invention, the two kinds of root control devices are adopted for planting and then transplanting and root cutting technologies are adopted, so that the growth of the nursery stock can be controlled, and the lateral root quality of the nursery stock can be rapidly improved, the pecan trees in the united states can be rapidly formed,and the purpose that the fruits can be hung in 2-3 years in advance compared with conventional cultivation management can be achieved.

Description

Technical field [0001] The invention relates to the field of crop cultivation, in particular to a method for promoting early fruiting of pecans. Background technique [0002] American pecan is a world-renowned high-grade oil, rare dried fruit tree species, rich in nutrition, 89% of the fat is unsaturated fatty acids, it is a high-grade brain food. [0003] The introduction of American pecans in China began at the end of the 19th century and the beginning of the 20th century. The seedlings used in the early introduction and cultivation were all seedlings. However, the childhood period of pecans is too long. Normally, the fruit-bearing time of seedlings is about 12 years, and it takes about 5 years for grafted seedlings to bear fruit. In recent years, due to breakthroughs in grafting technology, improved seedlings have been promoted and applied, with rapid development and continuous expansion of planting scale. The cultivation area in Jiangsu, Zhejiang, Anhui, Yunnan, Jiangxi, Shand...
