据埃及某农业研究所试验,用三西(CCC)处理红薯可提高块根产量。该试验在壤土中采用小区随机排列,母薯均匀切块播种。播后分早期(播后75天,即7月2日)和晚期(播后105天)两种喷射处理(每种处理只喷射一次)。三西浓度分为250、500和1,000PPm(百万分之)三种,对照喷清水。小区面积16平方米,重复4次,10月5日收获测定产量。试验结果如表列。早期处理中低浓度即有增产效果,当浓度增大后,增产更为显著,但最高浓度增产幅度反不如中等浓度。晚期处理也增产,但不如早期处理显著。
According to a test conducted by Egypt’s Agricultural Research Institute, the treatment of sweet potatoes with CCC (CCC) can increase tuber yield. The test in the loam in the district randomly arranged, potato chips were cut evenly. Seeding after the early (post-sowing 75 days, July 2) and late (post-sowing 105 days) two jet treatment (each treatment only jet once). San Xi concentration is divided into 250,500 and 1,000 PPM (parts per million) three, the control spray water. Residential area of 16 square meters, repeated 4 times, October 5 harvest measured yield. Test results as tabulated. Early treatment of medium and low concentrations that have the effect of increasing production, when the concentration increases, the yield is more significant, but the maximum concentration of anti-production rate of anti-moderate concentration. Late treatment also increased, but not as early treatment significantly.
