我所于1984午冬开展了主要果菜类蔬菜商品化育苗技术的研究。为了降低商品蔬菜苗的生产成本,使菜苗在较长途运输时能延缓萎蔫发生时间,提高移栽成活率,于1985年2月中旬至5月上旬以及9月中下旬,以中国科学院化学研究所提供的既可作土壤保水剂又可作移苗保水剂的高叹水性树脂KH841为材料,对几种蔬菜的幼苗开展了室内和田间试验,现将初步结果总结如下。
In the winter of 1984, I started the commercialization of fruit and vegetable vegetable nursery technology research. In order to reduce the production cost of commodity vegetable seedlings, the vegetable seedlings can delay the wilting occurrence time and improve the survival rate of transplanting in the long-distance transportation. From mid-February to early May and late-mid-1985, with the Chinese Academy of Sciences Institute of Chemistry Provided both for soil water retaining agent can also be used as seedling water retention agent sigh water resin KH841 material for several vegetable seedlings conducted indoor and field trials, the preliminary results are summarized as follows.
