植物源浸种剂“SNⅠ”在冬麦上的增产使用效果研究

A Study of the Plant Preparation of SN ⅠSeed-soaking Reagent on the Soaking-application Efficiency to Wheat

植物源浸种剂'SNⅠ'是以天然植物提取液为载体合成的一种无毒、高效、价格低廉的新型种子处理剂,具有增蘖、增穗、增抗、增绿、增粒、增重等多项功能.经小麦试验,一次浸种4～6 h,一般即可增产小麦8%～13%.在不同稀释浓度下的使用效果比较后认为,药水比例1 :4 000浸种4～6 h效果最佳.

Soaking--application of the plant preparation of SNⅠ seed-soaking Reagent to wheat can give multiple functions such as： increase in tillers, increase in spikes, increase in anti-reverse performances, increase in leaf chlorophyll content, increas e in the no of full grains, increase in 1 000 gw and increase in grain yield. The increase in wheat grain yield is generally amounted up to 8 % ～ 13 % with only once seed soaking-application. It gives the advantages of less cost, convenient application, stable efficiency, no residual toxicity and no pollution to enviroment. In this paper, the results of efficiency with different seed-soaking reagent dilution has been studied, it is finally concluded that the dilution of 1：4 000 being soaked 6 h is favourable.
