微量矿质元素及硅酸盐提高水稻抗瘟能力的作用已屡有报导。现在我们着重就草皮和草木灰,与几种单纯的矿物质加以比较研究。试验是在温室盆栽、土培(稻田土)的条件下进行的。所用的水稻品种为早粳Ⅱ—49—79,瓷钵30×27厘米。各种处理重复三次。按图1附注所示的分量,草皮和草木灰在栽秧前一次施入,各种矿物质配成一定浓度的溶液,在整个水稻生育期间,用以灌溉。对照不施肥,用清水灌溉。
The role of trace mineral elements and silicates in enhancing the blast resistance of rice has been repeatedly reported. Now we focus on the turf and ash, and several simple minerals to be compared. The experiment was carried out in the greenhouse pot, soil culture (paddy soil) under the conditions. Rice varieties used are early japonica Ⅱ-49-79, porcelain bowl 30 × 27 cm. The treatment is repeated three times. According to the components shown in the note of Figure 1, the turf and ash are applied once before planting and the various minerals are dosed to a certain concentration for irrigation during the entire rice growth period. Control without fertilization, irrigation with water.
