亚麻的倒伏问题是比较复杂的问题,有些方面还有待深入研究,根据我们初步观察调查结果,摘要於下: 1.品种之间对倒伏的抵抗性有相当大的差异,一般油用类型抗倒伏性强,纖维用类型2次之,纤维用类型1抗倒伏性较差;在同一类型中由於品种不同也有一定差异。在植株性状上株高舆茎粗比例对倒伏有一定的相关性,即有比例愈小倒伏愈轻的趋势。 2.栽培技术对亚麻的倒伏影响很大,一般播种量愈多则倒伏愈重,播种量少或米间株数少则倒伏也较轻;施用氮肥过多则易促进倒伏,增施钾肥不但能提高产量,而且也能减轻或防止倒伏,因此合理密植及適当增施氮磷钾肥料,是提高产量防止倒伏的重要措施之一。不同前作舆倒伏关系也甚密切,一般毂楂、高粱楂倒伏轻,小麦、玉米楂次之,大豆楂稍重,牧草楂最重。 3.风雨对於亚麻倒伏的影响也大,尤其当亚麻开花至成熟階段的多雨及大风,能促使倒伏更重。
Flax lodging problem is a more complex issue, some aspects have yet to be further study, according to our preliminary observations of the survey results, the abstract is as follows: 1. Varieties lodging resistance considerable differences, the general type of oil lodging Strong, fiber type 2 times, fiber type 1 lodging resistance is poor; in the same type due to different varieties are also some differences. In plant traits, plant height and stem diameter ratio had a certain correlation with lodging, that is, the smaller the proportion, the lighter the tendency of lodging. 2. Cultivated technology has a great influence on the lodging of flax, the more general sowing is, the heavier the lodging, the less sowing or the smaller number of rice, the lodging is also lighter; too much nitrogen fertilizer is easy to promote lodging, Improve yield, but also reduce or prevent lodging. Therefore, proper close planting and appropriate application of nitrogen, phosphorus and potassium fertilizers are one of the important measures to increase yield and prevent lodging. Before the different situation for the lodging of the relationship is also very close, the general huber, sorghum lodging light, wheat, corn, followed by hawthorn, hawthorn slightly heavier, the heaviest hawthorn. 3. The impact of wind and rain on the lodging of flax is also great, especially when the rainy and gale flowering of linen to maturity can lead to heavier lodging.
