1.要选择适宜的品种目前市场上出售的植物生长调节剂种类繁多,有广谱型的,如喷施宝、绿风95等;也有专用型的,如玉米壮丰灵等。使用时要有针对性地加以选择,切忌盲目随从。 2. 要掌握使用方法植物生长调节剂常用的方法有浸种、拌种、蘸根、灌根、叶喷和涂抹等,应根据使用目的来确定使用方法。一般以叶面喷雾为常见,要按使用说明操作。 3.不要随意改变使用浓度植物生长调节剂的使用浓度直接影响使用效果。浓度过大易使叶片增厚变脆,或畸形,或脱落,甚至全株死亡;浓度变小,达不到应用效果。所以,不能毫无根据地随意加
1. To select the appropriate varieties Currently on the market for the sale of a wide range of plant growth regulators, a broad-spectrum, such as Penshibao, Green Wind 95; also have special-purpose, such as corn Zhuang Feng Ling.
