保水剂SSA(以下简称SSA)是一种高分子化合物,已在北方干旱地区的许多作物上开始应用,在南方棉花生产上是否有应用价值,我们进行了初步的研究,现将种子涂层的试验结果报告如下。 经过和方法 1986年10～12月,结合南繁育种任务,在海南三亚市进行试验。设SSA种子涂层结合地膜覆盖以及播前沟施SSA 5个处理,种子经硫酸脱绒,每小区用种子100粒,3次重复。1987年试验在本所试验田内进行,设SSA种子涂层结合营养钵育苗3个处理。营养钵不加水处理,先加入必要的水分制钵,播种前不再加水;营养钵加水处理,播种前浇水至过饱和状态。
Super absorbent polymer SSA (hereinafter referred to as SSA) is a macromolecular compound, which has been applied in many crops in the northern arid areas and whether there is application value in the southern cotton production. We conducted a preliminary study, The test results are reported below. After the method and method from October 1986 to December 1986, combined with the task of breeding South propagation in Sanya, Hainan Province for testing. SSA seed coating combined with mulching and sowing pre-sowing SSA treatment 5, the seeds were stripped of sulfuric acid, per 100 seeds with three plots. In 1987, the experiment was carried out in our experimental field, and SSA seed coating was combined with three treatments of nutrition bowl breeding. Nutritional bowl without water treatment, the first bowl of water to join the necessary, no longer add water before sowing; nutrition bowl water treatment, watering to supersaturated state before sowing.
