1、 Soil selection
Acidic plants can only be raised with acidic soil, so we should choose acidic soil for breeding sunflower. If the breeding soil is alkaline soil, you can choose to add a little vinegar to the land or pour fermented rice washing water into the soil. Both of these things can change the pH of the soil and turn the alkaline soil into acidic soil. If you don't know how to distinguish the soil, you can test the pH value of the soil with pH test paper. If the index is greater than or equal to seven, it is alkaline soil, and less than seven is acidic soil. At ordinary times, we should also measure more, because the soil will change with the environment over time. If it becomes alkaline soil, we should take measures p>
2、 Soil preparation
In addition to pH, the permeability and drainage of soil should also be considered. The root system of sunflower is sensitive and needs to be cultivated with soil with good permeability and drainage. When configuring aquaculture soil, river sand, rotten leaf soil and peat soil can be configured in the ratio of 1:1:1, because river sand has good air permeability, rotten leaf soil has sufficient nutrients and peat soil has good drainage p>
3、 Increase nutrients
In the growth period of sunflower, it has a large demand for nutrients. It is difficult to meet its needs only by relying on the nutrients in the soil. It needs to increase nutrients through fertilization. When applying fertilizer, you can choose animal manure with low irritation and sufficient nutrients, which can be applied about twice a month. You can also choose to go to the store selling fertilizer and let professionals configure fertilizer according to the specific conditions of the soil p>
