摘要
采用穴盘育苗法,研究草木灰育苗基质对小白菜幼苗生长的影响。结果表明,小白菜在不同pH值的草木灰基质中生长不同,当pH值为9时,小白菜的生长明显受到抑制;当pH值为7时,小白菜的生长较好。在草木灰基质中补充氮肥可以促进小白菜的生长,氮肥用量为360~480 mg/kg时,小白菜的生长更好。在制作小白菜草木灰育苗基质时应考虑以纯硝态氮或酰胺态氮为氮源。
Using pug seedling method,effect of plant ash seedling matrix on seedling growth of Chinese cabbage was studied in this paper.The results showed that the growth of Chinese cabbage in different pH values was different.When the pH value was 9,the growth of Chinese cabbage was obviously inhibited.When the pH value was 7,the growth of Chinese cabbage was better.The growth of Chinese cabbage could be promoted by adding nitrogen fertilizer in the plant ash matrix.When the amount of nitrogen fertilizer was 360-480 mg/kg,the growth of Chinese cabbage was better.It is necessary to consider nitrate nitrogen or amide nitrogen as nitrogen source in the production of plant ash seedling matrix for Chinese cabbage.
