Key Points and Methods of Flax Fertilization Technology Explained

Flax is the earliest natural plant fiber used by humans. In addition, flax is also an oil crop, rich in unsaturated fatty acids, which can prevent high blood lipids and arteriosclerosis, giving it extremely high cultivation value. If you want to grow flax well, fertilization is extremely important. Let's take a look at flax fertilization technology below.

1. Nutrient requirements

During the growth process of flax, the nutrients required are relatively large, and they are irreplaceable, so during planting, the nutrients needed for flax growth must be supplied in a balanced way to achieve the goal of high yield and excellent quality. As for the nutrient requirements of flax, before growth it absorbs 10%, 5% and 4% of nitrogen, phosphorus and potassium; during the vigorous growth period, the absorption capacity rises significantly, and the demand for nitrogen, phosphorus and potassium is divided into 34%, 19% and 32%; by the flowering period, the cumulative absorption of nitrogen, phosphorus and potassium has reached more than 95%, and nutrient absorption decreases significantly in the later stage.

2. Apply heavy farmyard manure

Farmyard manure is a fertilizer that contains both quick-acting and slow-acting nutrients. Its nitrogen, phosphorus and potassium content is balanced, and it is also rich in various trace elements. It can increase ground temperature, enhance soil permeability, promote the activity of beneficial microorganisms, inhibit the growth of pathogens, and effectively reduce pests and diseases. Therefore, before planting, generally 2000 kg of farmyard manure per mu needs to be applied as base fertilizer, while adding 3-4 kg of nitrogen fertilizer and 5-6 kg of phosphate fertilizer. If the soil is deficient in potassium fertilizer, an appropriate additional application of 4-6 kg of potassium fertilizer can be made, which can achieve a significant yield increase effect. Generally, after sufficient base fertilizer is applied, there is no need for topdressing in the early growth stage, so farmyard manure should be applied heavily.

3. Reasonable topdressing

During the growth period, topdressing should be done reasonably according to the growth condition of the plants to ensure the nutrients needed for plant growth. Generally, nitrogen, phosphorus and potassium are used for topdressing. In the early growth stage, compound fertilizer mainly based on nitrogen fertilizer is applied to promote strong plant growth, and in the middle and late stages, phosphate and potassium fertilizers are added, which can enhance the disease resistance of the plants and increase yield. During the cotton maturity period, foliar spraying can be used to maintain the potassium fertilizer and other elements lacking in the plants, which has a significant yield-increasing effect.
