| 摘 要： | 以河南中牟为供试地点,对不同钾肥品种和罗布泊钾肥不同用量在大蒜上的应用效果进行了研究,以了解钾肥在大蒜上的应用效果.结果表明:不同钾肥处理都可以增加大蒜蒜薹、蒜头鲜重,蒜头瓣数、蒜头直径、茎周长,可以促进大蒜对氯素的吸收,提高Vc、蛋白质含量,但不同钾肥种类和用量袁现不同.利用回归方程求得罗布泊K2SO4的最佳经济效益施用量为253.5kg/hm2时,最大产值为33 495.5元/hm2.

| Abstract: | The experiment was done in Zhongmou Henan province to study the effects of diffenrent K sources on growth and benefit of Garlic.The results showed:using K was good for garlic bolt and clove yield,shaps of agriculture,absorption of N and K,the content of Vc and protein in garlic clove;At the same K rates of 300 kg/hm2 the Russia KCl was the best for garlic bolt yield and the content of protein in garlic clove,the Luo Bupo K2SO4 was the best for garlic clove yield and the content of Vc in garlic clove,the Kai... |
