Problems solved by technology

At present, the high-yield cultivation technology of walnut in the existing technology is at a low level, and the production is mainly based on "four sides" sporadic planting. The production factors such as walnut seedling cultivation, planting survival rate, preservation rate, yield per unit area, product processing, and market are still relatively low.

Embodiment 1

[0022] 1. Basic situation of the project area:

[0023] 1.1 The natural situation and walnut cultivation status of Baoshan City, Yunnan Province:

[0024] Baoshan City is located in the west of Yunnan, with an east diameter of 98°25′~100°02′ and a north latitude of 24°08′~25°51′, with a land area of ​​19637km 2 , of which mountainous areas account for 92%. The city governs 72 townships and four counties in Longyang District, Shidian County, Tengchong County, Longling County, and Changning County, with a population of 2.44 million. Baoshan City is located at the southern end of the West Yunnan Rift Valley of the Hengduan Mountains. The three major water systems of the Lancang River, the Nujiang River and the Irrawaddy River run parallel to each other throughout the whole area. The terrain is higher in the north and lower in the south; the altitude is 535-3780m; Rainy, rainy and hot in the same season, dry and wet distinct" low-latitude mountainous monsoon climate characterist...

Abstract

The invention discloses a seed selection method for the improved variety of a walnut and a high-yield cultivation method thereof, comprising the steps of: selecting 8 walnut local improved varieties which are suitable for cultivating at different areas, namely, protecting the first-the eighth walnuts; adopting ten measures, namely, selecting a good area (siting control technology), building a large pond (preliminary soil preparation technology), fertilizing a picul of stable manure (base fertilizer fertilizing technology and soil improving technology), planting a improved variety strong seedlings (improved variety strong seedlings technology), irrigating a picul of root-fixing water (root-fixing water technology), covering a mulching film (water-retaining technology), a set of scientific fertilizer management method (fertilizing technology), a set of cultivation fostering management technology (soil management technology), a set of normative shaping trimming technology (tree body management technology), and a set of systemic pest preventive measure (soil management technology); and promoting the yield of young tress, updating old trees and improving low-yield tress.

Description

[0001] Field: [0002] The invention relates to the field of biotechnology, in particular to a method for breeding improved walnut varieties and high-yield cultivation. Background technique: [0003] Walnuts are mainly distributed in Yunnan, Guizhou, western Sichuan, Hunan, Guangxi and southern Tibet, and are the most important economic forest species in Yunnan Province. The main concentrated distribution areas are in the Lancang River, Nujiang River, Honghe River and Jinsha River basins; and the pickled walnuts produced in the warm and cool areas of the Lancang River and Nujiang River basins have the best quality, the highest market price, and the best sales. At present, the high-yield cultivation technology of walnut in the existing technology is at a low level, and the production is mainly based on "four sides" sporadic planting. The production factors such as walnut seedling cultivation, planting survival rate, preservation rate, yield per unit area, product processing, an...
