First, the role of seaweed essence
Seaweed extract is a kind of organic fertilizer extracted from seaweed, containing rich growth factors, a variety of trace elements and plant hormones. It can promote the growth and development of plants, improve the yield and quality of crops, while improving the physical and chemical properties of the soil, promote the propagation of soil microorganisms, and increase soil fertility.
Second, the application method of seaweed essence
1. Suitable crops for seaweed extract
Seaweed extract is suitable for various crops, such as rice, wheat, corn, soybeans, vegetables, fruit trees and so on. At the same time, seaweed extract is also suitable for lawn, flowers, pot and other soil repair and improvement.
2. Application amount of seaweed essence
The application amount of seaweed essence should be determined according to the growing season and variety of crops, soil type and quality, climate and environment. Generally speaking, the amount per mu is about 1-2 kg. The specific application amount also needs to be adjusted according to local soil conditions and crop demand.
3. Application method of seaweed essence
Seaweed extract can be spread on the topsoil of crops or mixed with water and irrigated on the roots. Before spreading, the algae essence should be mixed well with the soil to avoid fertilizer clumps. After application, water should be timely to help the seaweed essence dissolve and penetrate, and promote crop absorption.
Three, the attention of seaweed essence
Step 1 Apply in moderation
Although seaweed extract has the effect of promoting crop growth, excessive application will lead to the increase of soil salt and organic matter content, thus affecting the growth and development of crops. Therefore, when applying seaweed essence, we should pay attention to appropriate application and control the amount and frequency of fertilization.
2. Environmental pollution
When applying seaweed extract, care should be taken to avoid pollution to the environment. Do not sprinkle seaweed essence into the water to avoid affecting the water quality. At the same time, do not fertilize in rainy days or high humidity environments to avoid fertilizer loss and volatilization.
