Embodiment 1

[0041] This embodiment is carried out at the teaching experiment base of Hexi University, including the following steps:

[0042] S1. Fruit collection: From the first ten days of August to the beginning of September, in Zhangye City, Gansu Province, in the Hongshawo Xanthania sorbifolium Seed Collection Garden, the mother plant with strong tree vigor, dense fruit, and no pests and diseases was selected as the seed collection plant, and the surface of the fruit changed from green to green After the seeds are gray and white, the seeds turn black, and the carpels are cracked, collect even, plump, and free from diseases and insect pests by picking or tapping to complete the fruit collection process;

[0043] S2. Seed cleaning and grading: Remove the peel and impurities from the collected Xantho sorbifolium fruits, select plump, neat, robust, and high-viability seeds as sowing materials, and divide the seeds according to their size and thickness ≧ 13.0mm. Large grade, 11.8-12.9mm s...

Embodiment 2

[0060] This implementation is carried out at the nursery base of Xichengyi Forest Farm of Ganzhou District Forestry Bureau, Zhangye City, Gansu Province, and the steps are the same as in Example 1.

[0061] However, S1, seed purchase: at the beginning of September 2016, we purchased plump and robust seeds from Shanxi Forestry Research Institute;

[0062] S3, post-ripening treatment of seeds: treating the seeds treated in S2 at 40° C. for 72 hours, so as to complete the post-ripening of the seeds and improve the vigor;

[0063] S7. Lamination matrix preparation: uniformly mix lamination sand, lamination vermiculite and lamination perlite according to 5:1:2 (V:V:V), add 10% water, mix with lamination matrix, Then stack and simmer for 2 hours.

[0064] S8, seed disinfection treatment: soak and disinfect the cooked S3 seeds with 1% sodium hypochlorite solution for 10 minutes;

[0065] S9. Low-temperature variable-temperature stratification treatment: mix the stratified matrix tr...

Embodiment 3

[0070] This embodiment is carried out at the Hongshawo seedling breeding base of the Qilian Mountain Water Conservation Forest Research Institute in Zhangye City, Gansu Province, and the steps are the same as in Example 1.

[0071] However, S1. Seed purchase: At the beginning of January 2016, the full and robust seeds of that year were purchased from the X. sorbifolium seedling base in Jingtai County, Gansu Province;

[0072] S3, post-ripening treatment of seeds: treating the seeds treated in S2 at 38° C. for 72 hours, so as to complete the post-ripening of the seeds and improve the vigor;

[0073] S7. Preparation of laminated matrix: uniformly mix laminated sand, laminated vermiculite and laminated perlite at a ratio of 1:5:2 (V:V:V), add 18% water, and mix with laminated substrate. Then stack and simmer for 2 hours;

[0074] S8, seed disinfection treatment: soak and disinfect the cooked S3 seeds with 2% sodium hypochlorite solution for 5 minutes;

[0075] S9. Low-temperatu...

Abstract

The invention discloses a xanthoceras sorbifolium Bunge seed low-variable temperature lamination membrane covering direct sewn seedling growing method which comprises the following steps: collecting fruits, sorting and grading seeds, carrying out after-aging treatment on the seeds, preparing lamination sand, preparing lamination vermiculite, preparing lamination perlite, preparing a lamination medium, sterilizing the seeds, carrying out low-variable temperature lamination and membrane covering, and the like. The method has the beneficial effects of being rapid in seed germination, high in seedling rate, rapid in seedling growth speed, low in seedling growing cost, high in seedling rate of seeds, simple and convenient in management, convenient in in-situ material obtaining, high in transplanting survival rate, good in seedling commodity property, and the like, and is applicable to large-scale seedling growing in nursery lands.

Description

technical field [0001] The invention relates to the technical field of cultivating woody economic crops, in particular to a method for direct-seeding seedling cultivation of sorbifolium sorbifolium seeds with low-variable temperature stratification and film covering. Background technique [0002] Xanthoceras sorbifolium Bunge is a perennial deciduous shrub or small tree of the genus Xanthoceras Bunge in the family Sapindaceae. It is a single species and is produced in northern my country and North Korea. It is native to the Loess Plateau in northern my country, and is naturally distributed at 32°-46° north latitude and 100°-127° east longitude, that is, to the west of Liaoning and the southwest of Jilin in the north, from Xiaoxian County in Anhui Province and southern Henan in the south, and to Shandong in the east. , west to Ningxia, Gansu. It is concentrated in Inner Mongolia, Shaanxi, Shanxi, Hebei, Gansu and other places, and a small amount is distributed in Liaoning, Ji...
