甘薯秋藤越冬育苗是利用甘薯藤蔓育苗的一项新技术,具有节省种薯、繁育系数大、早插增产等特点.我市石桥头镇经过五年的试验摸索,已初具生产规模,1998年该镇利用秋藤育苗741.2万株,占该镇当年所需薯苗的89.9%.本技术对各甘薯产区有一定的参考和推广应用价值,现将应用效果及育苗技术简述如下:一、应用效果(一)节省种薯 秋藤育苗与种薯育苗的最大区别在于不用种薯,避免薯块窑贮越冬易造成烂种、鼠害及孵种催芽等繁杂的技术环节.按我市常年甘薯栽培面积6.2
Sweet potato autumn and winter overwintering breeding seedlings is the use of sweet potato vine nursery a new technology, with the saving of seed, breeding coefficient, early insertion and production and other characteristics of Shiqiao Town in our city after five years of trial groping, has begun to take the production scale, 1998 In the year, the town used 7412000 strains of autumn rattan seedlings, which accounted for 89.9% of the required potato seedlings in that year .This technology has some reference and popularization and application value to each sweet potato producing region. The application effect and seedling raising techniques are briefly described as follows: First, the application effect (A) to save seeds Seedling autumn seedling and seedling nursery the biggest difference is that no seed potato to avoid over-winter storage of potato block can easily lead to rotten species, rodent and hatching germination and other complex technical links. According to me City annual sweet potato cultivation area of 6.2
