Embodiment 1

[0037] The method of the present invention is set to repeat 3 times, and two contrasts are set, contrast 1 (CK1 ) for sprouting seedlings, control 2 (CK 2 ) for transplanting seedlings. Implementation location: Dadi Ecological Industry Development Co., Ltd., Qujing City, Yunnan Province.

[0038] (1) the cultivation method of walnut semi-annual stock of the present invention:

[0039] 1. Seed treatment

[0040] The seeds of the seedling tree of the bubble walnut (J.sigillata Dode) are used as the rootstock to cultivate the seeds. The seeds are full-bodied, uniform in size, free of diseases and insect pests, free of mildew and rot, and mature, unroasted and unbleached seeds , After the seeds were shade-dried, they were sown on October 11 after soaking the seeds in 100ppm gibberellin solution for 5 days.

[0041] 2. Sowing

[0042] The soaked seeds described in step 1 are planted on the ground bed, and the described ground bed is made into a moisture surface with a height of...

Embodiment 2

[0100] The method of the present invention was repeated 3 times, and two controls were set, and the two controls were respectively the same as the controls described in Example 1 (3) and (4), and will not be repeated here. Implementation location: Jianshui seedling breeding base of Senyang Forestry Industry Co., Ltd., Jianshui County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province.

[0101] Present embodiment (one) the cultivation method of the present invention's method walnut half-year stock is except that the measure listed in table 1 is different, all the other methods are identical with the cultivation method of the walnut half-year stock of the present invention described in embodiment 1 (one), repeat no more.

Embodiment （ 2

[0102] Present embodiment (two,) the cultivation method of half-year stock walnut seedling of the present invention is except the stock seedling that cultivates with the method described in present embodiment (one) as the stock of grafting, and all the other methods are described in embodiment 1 (two) The cultivation method of walnut seedlings half a year stock of the present invention is identical, repeats no more.

[0103] The rootstock seedlings cultivated in this example grow robustly, without diseases and insect pests, without mechanical damage, with complete root systems and many fibrous roots. The stem diameter of the rootstock seedlings reaches 0.5 cm to 2.0 cm, and the stem length is calculated from the base of the rootstock stem. The stems are 5cm to 7cm long, therefore, the grafting interface is relatively high, and the seedlings (transplanting) after grafting are easy to survive, and they are high-quality rootstock seedlings.

[0104] The survey of the rate of emer...

Abstract

The invention discloses a walnut semi-annual stock and a cultivating method of semi-annual stock walnut seedlings, belonging to the technical field of forest cultivation. The cultivating method of the semi-annual walnut stock comprises the following steps of: with same year seeds of a Sigillate walnut seedling tree as seeds for stock cultivation, treating the seeds, sowing the seeds into a ground bed in autumn in the same year, covering mulching films and constructing a plastic film arched shed, and controlling the temperature in the shed to 16-20 DEG C before euphylla of the seedlings is expanded, covering a sunshade net with the light transmittance of being 20-30 percent, wherein the soil water content is 40-50 percent; and after the euphylla of the seedlings is expanded and before graft is carried out in February and March of the next year, controlling the temperature in the shed to 15-25 DEG C, the light transmittance of the sunshade net to 40-60 percent and the soil water content to 40-60 percent. The semi-annual stock cultivated by using the cultivating method is used for cultivating the semi-annual stock walnut tree seedlings through grafting. The cultivating method disclosed by the invention is short in cultivation time, the average outplanting rate of the walnut seedlings is up to 87.7 percent which is increased by 25.5-67.4 percent in contrast, and the seedling raising cost is reduced in comparison with that of a bud stock.

Description

technical field [0001] The invention relates to the technical field of tree cultivation, in particular to a method for cultivating walnut stock and walnut seedlings. Background technique [0002] Juglans is a world-renowned economic forest tree species. Yunnan Province is one of the origins of walnuts and the main production area of ​​walnuts in the country. Its planting area and output account for about two-thirds of the country. Walnut is a "leading industry" that promotes the poverty alleviation of farmers in mountainous areas and drives the overall development of the rural economy in mountainous areas. It has become a pillar industry of forestry in Yunnan Province. In recent years, in addition to the large demand for walnut seedlings in this province, it has also been supplied to surrounding provinces such as Guizhou, Sichuan, Chongqing, and Guangxi. The annual demand for walnut seedlings is about 50 million. Therefore, the development of walnut industry cultivation is b...
