| 摘 要： | 为防御东北玉米低温冷害,研制了一种新型的玉米抗低温助长剂,其抗低温效果已为人工温控试验所证实。本项研究采用分期播种、地理播种和田间多处理对比试验方法,检验该化学制剂在影响玉米发育、生物量及产量性状方面的实用效果,并探求其适宜的浓度配比和喷施期次。研究结果表明,该制剂具有促生长、促早熟和使作物高产的性能,可防御延迟型冷害。施用时以1：400倍液和在营养生长期内两次喷施为佳。 |

| Abstract: | A new low-temperature-resistant and growth-helping medium is developed for defending corn from chilling damage in Northeast China. The effect of the medium is tested by experiments with artificial controlling temperature. In this study, a comparative experiment with seeding by stages and in different regions, and multi-treatments in field were used to examine its practical effect on corn growth, biomass and yield, and search suitable concentration composition and spraying stages and times. The result shows that this medium has a performance of promoting growth and maturity, increasing yield, and can defend corn from chilling damage. The best concentration is 1:400, the best stage is in nutrent growth period and two times spray in practical usage. |
