Amoy rice water asparagus missed this step no wonder the yellow leaves and rotten roots

Rice washing water can be used to irrigate asparagus, because it contains nutrients needed for plant growth, but fermentation must be carried out before irrigation, otherwise it will make the soil hardened. The fermentation time is about 1 month in winter and 10 days in summer. It needs to be diluted with water before watering to prevent root burning.

1. Reasons

Rice washing water is acidic, which contains a variety of nutrients needed for plant growth, including phosphorus. Phosphorus can differentiate the leaves and buds of plants, which is conducive to flowering. It also contains iron, which can prevent iron deficiency chlorosis. If rice washing water is often poured, the color of its branches and leaves will be more vivid.

2. Practice

Put the rice washing water into the empty jar and seal the mouth tightly. The fermentation time depends on the season. It can be used after about 1 month of decomposition in winter and about 10 days in summer. It needs to be diluted with 70%-80% water before it can be used for irrigation.

3. Precautions

Bamboo can not be watered with unfermented rice washing water, otherwise it will cause soil hardening, resulting in poor respiration of roots, and the accumulation of unfermented ingredients in rice washing water, fermentation in the soil, heat, will cause bamboo rotten roots, yellow leaves, dry leaves and so on. If you must use unfermented rice water to irrigate flowers, it must be precipitated or diluted.

In the growth period, we should pay attention to watering, water shortage is easy to cause the leaf tip of asparagus dry. At the same time also appropriate fertilization, should choose nitrogen, potassium mixed fertilizer.
