| China is one of the world’s walnut origin,has a long history of cultivation,is the world’s largest country walnut production,and the average annual output also ranked first.Yunnan is the Kingdom of Huaxia Walnut Planting,and “Yangbi walnut” is an excellent variety in Yunnan Province.It is famous both at home and abroad.There are32 varieties of large walnut,small walnut,and iron walnut.As of 2018,the area of walnut cultivation in Yangbi County reached 1.07 million Mu,the output volume was51,000 tons,the output value was 1.137 billion yuan,and the per capita income of farmers was 5,800 yuan,Therefore,walnuts became an effective pillar industry for the economic development and poverty alleviation in Yangbi County.However,for a long time,there has been a large number of use of fertilizers,pesticides and other phenomena in the management of walnut cultivation in Yangbi County,resulting in a series of problems such as walnut production,quality decline,soil compaction and environmental pollution.Biogas slurry is a green and pollution-free high quality organic fertilizer,which can improve the quality of walnut and promote the sustainable development of walnut industry.Therefore,it is proposed to promote the technology of walnut cultivation in Yangbi County.This paper adopts the methods of literature,field investigation and expert interview,lessons Learned Method,analyzed the Yangbi County promotion marsh fertilizer kinds of walnut technical qualifications.Concluded that use Yangbi County marsh fertilizer production 1.58146 million tons of animal manure can completely meet the highest 1.07 million tons of fertilizer requirement in walnut planting,according to the experience of using bog fertilizer for various crops in Dali prefecture,Yunnan province,Yangbi County marsh fertilizer farmers planting walnut practice base,And the effect of improving the quality and increasing the efficiency of walnut planting with biogas slurry,Serve as a reference for Yangbi County marsh fertilizer plant walnut.Countries at the same time,Yunnan province,Dali prefecture,and Yangbi County related policy support the development of the examples of walnut industry and marsh fertilizer plant walnut;Promote the cultivation of walnutfertilizer,can effectively alleviate the harm caused by chemical fertilizers and pesticides,help to improve walnut quality and development of organic walnut industry,at the same time,can bring better economic benefits.The popularization and application of biogas slurry,can effectively solve the Yangbi County livestock waste pollution problem,and can support organic walnut industrial development,therefore,popularized in Yangbi County marsh fertilizer plant walnut technology is feasible and necessary.The techniques of walnut planting with marsh fertilizer were summarized.Basal(either with annular fertilization、radial fertilization):Base fertilizer(with circular fertilization,radioactive fertilization can be): from November to December each year,the amount of marsh residue used in young trees is 12 to 60 kg/plant(1 to 6 years),and the initial result is 90 to 150 kg/plant(7 to 15 years),The fruit period is 300 ~ 600kg/plant,> 200 kg/plant(> 16 years).In mid-April,mid-May,and early July of the following year,fertilizer is chased.The young tree period should be 20 ~ 40 kg/plant.80 ~ 150 kg/plant,The fruit period should be 200-250 kg/plant,and at the same time in early April and early May of the following year,the concentration of 30 % marsh fluid was used as leaf surface dressing.Present situation of Yangbi County requirements,formulated the biogas slurry plant walnut technology promotion scheme,the main around two aspects :clear positioning of strategic goals-concept change,formulate and improve relevant policie,will be abandoned biogas tank restart;develop the promotion plan in three stages:Propaganda stage:to improve people’s ideological awareness;The stage of demonstration and technology application and promotion : combining theory and practice through“demonstration driving”;All-the-way tracking service stage:ensure that the technology can implement for a long time,finally achieve success in Yangbi County the technology promotion. |
