不同类型叶面肥、生物调节剂对大蒜生长发育的影响

Effects of different foliar fertilizers and biological regulators on the growth of different types of garlic

在大蒜返青期至花芽鳞芽分化期,采用叶面喷施的方法,研究了不同类型叶面肥和生物调节剂处理对不同类型大蒜地上部植株和地下部鳞茎生长的影响。结果表明,不同处理对紫皮蒜品种济蒜3号的影响相对较大,对白皮蒜品种金乡白皮蒜的影响较小,但均能提高2种类型大蒜品种的抽薹性状和蒜薹产量。枯草芽孢杆菌叶面喷施对济蒜3号地上部植株生长具有较好的促进作用,枯草芽孢杆菌、大量元素水溶肥喷施对济蒜3号地下部鳞茎具有较好的促进作用,能够显著提高鳞茎产量和商品品质。腐殖酸水溶肥喷施能够促进金乡白皮蒜地上部植株和地下部鳞茎生长。

During the period from garlic turning green to flower bud differentiation,the effects of different types of foliar fertilizers and biological regulators on the growth of aboveground plants and underground bulbs of different types of garlic were studied using the method of foliar spraying.The results showed that different treatments had a relatively significant impact on the purple garlic variety Jisuan No.3,while had a relatively small impact on the white garlic variety Jinxiang White Garlic.However,both treatments could improve the bolting traits and yield of the two types of garlic varieties.Foliar spraying of bacillus subtilis could promote the growth of aboveground plants of Jisuan No.3.Spraying of bacillus subtilis and macronutrient water soluble fertilizer had a better promotion effect on the underground bulbs of Jisuan No.3,which could significantly improve the yield and commodity quality of bulbs.Spraying humic acid water soluble fertilizer could promote the growth of aboveground plants and underground bulbs of Jinxiang White Garlic.
