1. Cause

Rice washing water is acidic, which contains a variety of nutritional elements required for plant growth, including more phosphorus. Phosphorus can make the leaf bud of the plant differentiate, which is conducive to flowering. It also contains iron, which can prevent iron deficiency chlorosis. If you often pour rice washing water, the color of its branches and leaves will be more bright.  

2. Practice

Seal the rice in the jar. The fermentation time depends on the season. It can only be used after about one month's ripening process in winter and about 10 days in summer. It needs to be diluted with 70% - 80% water for irrigation

3. Precautions

Asparagus cannot be watered with rice washing water without fermentation, otherwise it will cause soil hardening, resulting in poor breathing of roots. Moreover, there is a large accumulation of unfermented components in rice washing water, which will cause rotten roots, yellow leaves, dry leaves and so on. If it is necessary to use unfermented rice washing water to irrigate flowers, it must be precipitated or diluted

During the growth period, pay attention to watering. Lack of water is easy to cause the leaf tip of asparagus to dry up. At the same time, proper fertilization should be carried out, and the mixed fertilizer containing nitrogen and potassium should be selected
