1、 Cake fertilizer

When fertilizing asparagus, cake fertilizer can be applied, that is, the residue left after oil extraction. After collection, it can be used directly, which can make the plant stem stronger and grow more vigorously. Pay attention to the dosage when applying fertilizer. Do not use too much or work too often. It is usually applied once every ten days or so to avoid burning the root system

2、 Rotten rice washing water

At ordinary times, the water for washing rice can be collected and fermented in the sun. After complete fermentation, it can be mixed with an appropriate amount of water. It can also be used as fertilizer, which is beneficial to the growth of asparagus. However, it should be noted that this can not replace watering and can not be applied too frequently to avoid affecting growth

3、 Expired yogurt

When making fertilizer, you can also use expired yogurt as raw materials. Dig it out and put it into a plastic bottle for fermentation. It will take about ten days. After fermentation, add 20 times water to dilute, and then irrigate the plant, which can make it grow more vigorously. Because yogurt contains many fungi, it is rich in nitrogen after fermentation, which is conducive to growth

4、 Precautions

When fertilizing it, it's best to apply diluted fertilizer solution. Pay attention to the proportion, about 1:15. Don't overdo the fertilizer, otherwise it's easy to burn roots. When applied, the fertilizer solution can be sprinkled on the roots or leaves, which can be absorbed
