石刁柏又名芦笋,含有丰富的氨基酸和多种维生素,是一种品味兼优的名贵蔬菜。我校于1984年以来从青海、天津、省农科院等地先后引进了部分品种(系)试栽结果证明,当地的土壤、气候条件均适宜芦笋生长。但因其种子比较昂贵,采用一般育苗方法出苗率较低,不易出全苗,土地利用率不高。同时,由于芦笋为多年生,幼苗生长的强弱,直接影响产量和经济效益。为了解决上述问题,根据当地气候条件特征,采用了地膜覆盖育苗,获显著效果。其技术要点如下:
Asparagus, also known as asparagus, is rich in amino acids and vitamins, is a taste of both expensive vegetables. Our school from 1984 in Qinghai, Tianjin, Provincial Academy of Agricultural Sciences and other places have introduced some varieties (lines) planted test results show that the local soil and climatic conditions are suitable for the growth of asparagus. However, because of its seeds are more expensive, using the general method of seedling emergence rate is lower, not easy to seedlings, land utilization is not high. Meanwhile, asparagus perennials, the strength of seedling growth, a direct impact on yield and economic benefits. In order to solve the above problems, according to the characteristics of the local climatic conditions, the use of plastic film cover nursery, a significant effect. The technical points are as follows:
