壮秧剂是一种新型高效药剂,广泛应用于早育秧。为了配合全国农技总站的推广,我们近几年在旱育抛秧上研究了壮秧剂的应用。壮秧剂的应用效果1.使用壮秧剂,能育成矮健、多蘖的秧苗,可有效提高秧苗素质。在常规旱育抛秧情况下,秧苗分蘖株率、大蘖率、单株带蘖均得到提高,同时增大了秧苗的干鲜比率2.35个百分点,单株带蘖多0.42个,大蘖率多10.20个百分点;在塑料软盘旱育抛秧的情况下,使用壮秧剂可提高干鲜比率2.83个百分点。单株带蘖多0.5个,分蘖株率多14.97个百分点,大蘖率多2.92个百分点。2.使用壮秧剂能协调产量构成因素间的关系,增加
Strong seedling agent is a new type of highly efficient agents, widely used in early seedlings. In order to cooperate with the promotion of China National Agricultural Technology Terminus, we have studied the application of strong seedling agent in drought-tolerant throwing seedlings in recent years. Application effect of strong seedling agent 1. Use strong seedling agent, can grow into short, more tiller seedlings, can effectively improve the quality of seedlings. Under the condition of conventional watering and throwing seedling, the tillering rate, tillering rate and tillering per plant of seedling were increased, while the dry-fresh ratio of seedling increased by 2.35%, the number of tillers per plant was 0.42, the tillering rate More than 10.20 percentage points; in the case of plastic floppy seedling throwing seedlings, the use of strong seedling agent can increase the dry-fresh ratio of 2.83 percentage points. There were 0.5 more tillers per plant, 14.97% more tillers, and 2.92% more tillers. 2. The use of strong seedling agent can coordinate the relationship between yield components, increase
