| 摘 要： | 通过对抗旱剂一号在川西北地区小麦上拌种和在不同时间以不同剂量喷雾两方面研究,结果表明:拌种能增加小麦三叶期、五叶期的次生根数、根长及其地上部的鲜、干重,能减少无效分蘖数,提高上林率。抗旱剂一号拌种、分蘖期和孕穗期喷雾均能增加小麦的单穗绿叶数。拌种最佳剂量为50kg麦种200g,喷施的最佳时期和最佳剂量分为分蘖期,每公顷300g。拌种和喷施对产量均无显著影响、其优势主要在前期。

| Abstract: | The experiment was carried out in Northwest of Sichuan area which the antidrought material No. 1 was dressed with wheat seed and sprayed to leaves of wheat in different time. The results showed that seed dressing could increase the amounts and the length of secondary root in third and fifth leaf period of wheat as well as the fresh weight, dry weight of the plant over ground, and decrease the amounts of ineffective littering, improve the rate of head-bearing and the green leaf amounts of each ear. The optimum dosage of seed dressing is 200g every 50kg wheat seed. The optimum stage and dosage of spraying is 300g every ha. in littering stage. |
