无锡市郊区曾对茭白主产区3000余亩田进行了抽样调查和召开老农座谈会,一致认为要提高茭白的产量,必须要先提高种子纯度,在此基础上,形成一个合理的产量结构和加强治虫防病等工作。因此,1984～1985年,我们从选种、栽插、施肥、管水、治虫防病这五个方面进行了栽培无锡夏、秋茭白每亩产量30担的试验,现就秋茭生产的情况总结如下: 一、材料和方法 1984、1985年分别用广益茭白在广益乡尤渡村凌巷进行试验,试验田面积各年为3.27亩、3.07亩;土质均为重粘土,分别含速效氮240.8ppm、258.4ppm,速效钾95.2ppm、
In the outskirts of Wuxi City, a sample survey of 3000 mu of farmland in Baobei main producing area was conducted and a forum of farmers was held. It was agreed that in order to increase the yield of wild rice, we must first increase the purity of the seeds, and on this basis, form a reasonable yield structure and Strengthen pest control and other work. Therefore, from 1984 to 1985, we conducted experiments on the cultivation of Wuxi summer and autumn vernal white per acre production of 30 farmers from five aspects: planting, planting, fertilization, water management, pest control and disease prevention. Summarized as follows: I. Materials and Methods 1984 and 1985, respectively, with the benefits of white Guangyi You crossing the village of Ling Lane test lane, the experimental area of 3.27 mu each year, 3.07 acres; soil are heavy clay, respectively, with available nitrogen 240.8 ppm, 258.4 ppm, available potassium 95.2 ppm,
