为探索小麦叶面喷洒土面增温剂等化学药剂对叶面气孔开关状态、减少叶面蒸腾的影响,以及在发生干热风时防灾增产的效果,作者做了如下试验: 试验在小麦灌浆后期6月29～7月20日进行。药剂有四种:酸渣——膨润土制剂,酸渣——高碳醇制剂,酸渣——碳化物制剂(以上三种为改进了的土面增温剂),石油助长剂。试验结果:1.喷药对小麦植株外部形态的影响。用药后灌溉地、旱地小麦同对照地小麦相比,其共同点是叶面结一层薄膜,浅黄色,有光泽,如同腊质涂沫一般。晴天中午观察,叶平展,很少发生卷缩现象;喷药后植株青绿,有贪青趋势。2.用药后叶面气孔开关状况;晴天中午,用药
In order to explore the effects of chemical agents such as wheat leaf surface spraying soil surface warming agents on leaf stomatal state and leaf transpiration, and the effect of disaster prevention and stimulation in the event of dry and hot wind, the author did the following experiment: Late June 29 ~ July 20. There are four kinds of agents: acid residue - bentonite, acid residue - high carbon alcohol preparations, acid residue - carbide formulations (more than three kinds of improved soil warming agent), petroleum boosters. Test results: 1. Effect of spraying on the external morphology of wheat plants. Irrigated land, dry land wheat compared with the control of wheat, the common ground is a knot film, light yellow, shiny, like wax coated in general. Observed sunny noon, flat leaf, rarely curled phenomenon; plant green after spraying, a greedy trend. 2. After treatment leaf stomatal switch condition; sunny at noon, medication
