在施有机肥及氮、磷化肥的旱地，用ＷＳＣ种衣剂处理小麦种子，可增加小麦分蘖，促进根系生长，提高根系活力及其对氮、磷、钾等养分的吸收能力，使小麦幼苗生长量，尤其是地下部生长量显著增加，旗叶叶绿素含量明显提高，使亩有效穗数及亩穗粒数均较对照显著增加。不同施肥条件下，ＷＳＣ种衣剂增产效果以化肥区最高（１９．１％～２１．９％），有机肥区次之（１０．３％～１１．９％），有机肥与化肥配合区较低（１０．０％～１０．７％），无肥区增产效果最低（７．９％～９．２％）．因此旱地施ＷＳＣ种衣剂应主要用于长期单施化肥地块为好。
In the dry land with organic manure and nitrogen and phosphorus fertilizer, WSC seed coating treatment of wheat seeds can increase tillering of wheat, promote root growth, improve root activity and its absorption of nutrients such as nitrogen, phosphorus and potassium, so that wheat seedlings The amount of growth, especially the growth of the underground part, increased significantly and the content of chlorophyll in the flag leaf increased obviously, which made the number of effective panicle per acre and the number of per acre grain increased significantly compared with the control. Under different fertilization conditions, the effect of WSC seed coating production was the highest (19.1% ~ 21.9%) in fertilizer area, followed by organic fertilizer (10.3% ~ 11.9%), and that of organic fertilizer and chemical fertilizer Lower (10.0% ~ 10.7%), no fertilizer area yield the lowest (7.9% ~ 9.2%). Therefore, dry land WSC seed coating should be mainly used for long-term single fertilizer plots as well.
