The latest course on fertilization techniques and methods of flax

Flax is the earliest natural plant fiber used by human beings. in addition, flax is also an oil crop, which is rich in unsaturated fatty acids and can prevent hyperlipidemia and arteriosclerosis. If you want to grow flax well, fertilization is very important. Let's take a look at the fertilization technology of flax.

1. Characteristics of fertilizer requirement

In the process of flax growth, the nutrients needed are relatively large, and they are irreplaceable, so it is necessary to balance the supply of nutrients needed for flax growth in order to achieve the goal of high yield and high yield. For the fertilizer characteristics of flax, the absorption quality of nitrogen, phosphorus and potassium before growth was 10%, 5% and 4%, while in the peak growth period, the absorption capacity increased significantly, and the demand for nitrogen, phosphorus and potassium was 34%, 19% and 32%. At the flowering stage, the cumulative absorption of nitrogen, phosphorus and potassium was more than 95%, and the nutrient absorption decreased significantly in the later stage.

2. Heavy application of farm manure

Farm manure belongs to the fertility of both quick-acting and late-acting nutrients, its nitrogen, phosphorus and potassium content rubber ring, but also rich in a variety of trace elements, can increase soil temperature, enhance soil permeability, promote beneficial microbial activities, inhibit the growth of bacteria, and effectively reduce diseases and insect pests. Therefore, before planting, it is generally necessary to apply 2000 kilograms of farm manure per mu as base fertilizer, while adding 3-4 kilograms of nitrogen fertilizer and 5-6 kilograms of phosphate fertilizer. If the soil with insufficient potassium fertilizer can be properly increased by 4-6 kilograms, it can obviously increase the yield in the end. Generally speaking, after applying sufficient base fertilizer, there is no need for topdressing in the early stage of growth, so it is necessary to re-apply farm manure.

3. Reasonable topdressing

During the growing period, it is necessary to apply reasonable topdressing according to the growth status of the plant to ensure the nutrition needs of the plant growth. generally, three kinds of nitrogen, phosphorus and potassium are used in the topdressing, and the compound fertilizer based on nitrogen fertilizer is mainly applied in the early stage of growth to promote the strong growth of the plant. the application of phosphorus and potassium fertilizer in the middle and later stage can enhance the disease resistance of the plant and increase the yield. In the mature stage of cotton, the lack of potassium fertilizer and other elements in the plant can be maintained by foliar spraying, which can obviously increase the yield.
