Flax planting technique

Flax is an annual herb, which can be used to make cloth and has the effect of absorbing sweat. At present, flax is being planted in many areas. What are the planting techniques of flax?

1. Soil selection and land preparation

Flax like cool and humid climate, cold-resistant, afraid of high temperature, suitable for planting in deep soil, loose and fertile soil, good drainage soil, preferably before planting corn, wheat and other crops. In addition, the seeds of flax are relatively small, and the soil strength at the top of the bud is weak, so soil preparation before planting is a necessary process. Remove the weeds and debris from the planting land, then turn the soil deeply, and then smash a large piece of consolidated soil, which is loose and fine.

2. Seed selection and treatment

The selection of improved varieties before planting is the primary condition to achieve high yield and high yield. excellent varieties with strong adaptability, strong disease resistance and in line with local planting conditions are selected. The seeds used for sowing should be full and defect-free seeds, remove small seeds with impurities, and put the seeds in the sun for 1-2 days, which can improve the germination rate. In order to prevent diseases, you can use chemicals to treat the seeds.

3. Sowing seeds

The climate and soil environment are different in each region, so the sowing time is also slightly different. Generally, the sowing time is in early May. When sowing, we should pay attention to the sowing density, sowing too closely, there will be the phenomenon of grabbing light and nutrients, resulting in many seedlings with slender stem, plant height, but easy lodging, and low yield; but insufficient sowing, flax stem stout, but many branches, poor quality and yield, low economic benefits. Generally sowing 100kg-110kg per hectare, about 2000 seedlings per square meter.

4. Field management technology

The main results are as follows: (1) rational fertilization: flax has a greater demand for fertility during its growth, especially for nitrogen and potassium, but less for phosphate, and the demand for fertility is different in each growth stage. There is a great demand for nitrogen fertilizer in the early growth stage, potash fertilizer in the peak growth season and flowering stage, and a large amount of phosphate fertilizer in the flowering stage. However, fertilization should not be excessive, which is not as good as excessive application of nitrogen fertilizer, which leads to plant lodging and excessive application of phosphate fertilizer, which will lead to plant dwarfing and premature senescence. Flax root system is weak, fertilization should be based on base fertilizer, topdressing as a supplement, but also pay attention to other trace elements.

(2) weeding: weeds have a great effect on the yield and quality of flax. If the growth is not as good as weeds in the early growth stage, it will affect the growth of flax. Weeding must be clean and thorough, in addition to artificial, but also can be medicament weeding.

(3) Prevention and control of diseases and insect pests: the main diseases of flax are blight, anthracnose, Fusarium wilt and powdery mildew, and the pests are mainly transported to flies and moths.
