Sharma等(1984)曾报道,由于马铃薯播种量大,浸种处理能为其供给一些养分。但薯块浸种处理有利也有弊,弊病是使作物出苗不良。用代森锰锌处理虽减少了对出苗的不利作用,但增加成本。因此为了降低处理成本而又有效,本研究试图在两种农业气候条件下找出薯块在水中和盐溶液中浸种的安全时期及其对产量的影响。盆栽试验于1981年冬季在印度Shimla的酸性丘陵土壤上进行,4种处理如下:1.未浸种,2.水浸4小时,3.1％NaHCO_3溶液中浸2分钟,4.1％NaHCO_3溶液中浸1小时。各重复5次。
Sharma et al. (1984) reported that, due to the large amount of potatoes planted, soaking treatment can provide some nutrients. However, soaking potato seed treatment is good and bad, the drawback is to crop poor emergence. Although treated with mancozeb reduced the adverse effects of emergence, but increased costs. Therefore, in order to reduce the processing cost and be effective, this study tried to find out the safe period and its effect on the yield of potato seed soaking in water and salt solution under two agricultural climatic conditions. The pot experiment was conducted on the acidic hilly soils of Shimla, India in the winter of 1981 with the following four treatments: 1. Immersed, 2. Immersed for 4 hours, immersed in 3.1% NaHCO 3 solution for 2 minutes and in 4.1% NaHCO 3 solution for 1 hour . Repeat five times each.
