The High Efficient Planting Technology Of Scallion Exporting To Japan

According to requirment and quality standard of the import country on holding greenness scallion,we summarized the fitable technology of export scallion in shanghai area and coustructed 4 standardization process base.At the same time,we confirmed the optimal model by combining characteristic of this area and domestic market,surrounding key technology of influencing the quality of export scallion.The key technology included planting style,planting breed,seedtime in planting management,method,seedling standard,fixed planting time and density and methods, management of water and fertizer,method of earthing up,prevention and cure of plant diseases and insect pests,technique of harvest and processing,high efficiency stubble and so on.The application of the technique has obtained better social and economical benefit.The total planting area of scallion has been added up to 620hm2 till October 2004. In 2003~2004,the planting area is 146.7hm2, the total yield and total production value is 8020000kg and 7.76 million yuan respectively , the average yield is 54647.7kg/hm2 and the production value is 52878.6yuan/hm2,the output of a unit of area and the quatity of finished product increase 6.8% and 9.56% respectively compared last year's.This technique will spread step by step,At first it is led the way in the builtvegetable base,then spread to the area possessing the operating environment by spot direction,technical training and research,compiling and distributing technical data et.The technique promote the realization of agricultural producing scalization, industrialization and modernization in shanghai area.
