Application of Biogas Liquid in Chinese Cabbage Planted in Early Spring

早春大白菜叶面喷施沼液能有效地促进白菜的生长，达到结球结实，提早上市，增产增收，平均单产较喷清水对照增产8．54％，产值增收109．30元／667m^2，与喷施1000倍绿神营养液相比产值低0．13个百分点，但喷施1000倍绿神营养素白菜品质不如喷施沼液的好。建议生产中使用沼液进行大白菜叶面喷施。

The foliage spray with biogas liquid can effectively promote growth of Chinese cabbage planted in early spring, harvest it early and increase its yield and output value. The yield and output value of foliage dressing with biogas liquid are 8.54% and 109.30 yuan/667m^2 higher than those of CK respectively. The output value of foliage dressing with biogas liquid is 0.13% lower than that spraying the nutrition liquid but its quality is better than that spraying the nutrition liquid. Therefore, the foliage dressing with biogas liquid should be popularized in Chinese cabbage production.
