When is flax planted? How do you plant it? Please put away the technical guidance for flax production in 2020!

Flax is a kind of oil crop, also known as Jusheng, square stem, oil flax, fat flax, planted in China's three series, Gansu, Ningxia and other provinces. When is the flax growing season? How do you plant it? What are the technical guidelines for flax production in 2020? Let's take a look at it.

When is the season for growing flax?

Flax is generally planted in spring, when the soil temperature is stable at 7-7.5 ℃ and the soil water content is not less than 20%, it is appropriate to sow from the end of April to the beginning of May.

Second, how to grow flax? Technical guidance on flax production in 2020

Flax is one of the main oil crops and cash crops in the cold and arid areas of northwest and north China. This year, the heat conditions and soil moisture in the northern region are better, which is conducive to the realization of adequate moisture sowing of flax at the right time. At present, flax sowing in northwest and North China has been carried out one after another. in order to promote the stable yield and income of flax, the National Agricultural Technology extension Service Center and the Oil expert guidance Group of the Ministry of Agriculture and Village have put forward technical guidance for flax production in 2020.

First, a reasonable rotation, select a good stubble. Continuous cropping and successive cropping easily lead to the aggravation of diseases such as flax Fusarium wilt, the accumulation of weed seeds and the serious imbalance of nutrients. Therefore, flax should generally practice more than 3 years of rotation, and should be mixed with wheat, corn, potatoes, legumes, green manure crops, etc., while the land with serious Fusarium wilt requires a longer rotation interval, and the rotation cycle is generally more than 5 years.

The second is to prepare the soil as soon as possible and sow seeds at the right time. Soil thawing 3-5 cm timely ploughing and harrowing, combined with soil preparation, apply sufficient base fertilizer. According to the natural ecology and production conditions of various places, the excellent varieties with suitable ripening period, high resistance to Fusarium wilt, strong resistance and passed the national variety registration were selected. The sowing time is generally from late March to early April in Northwest China, and from mid-late April to early May in North China.

The third is to adjust measures to local conditions and supporting technology. In the northwest arid region, the drought-resistant and high-yield cultivation techniques of flax with plastic film hole sowing as the core technology were adopted, including no-tillage hole sowing with old film, hole sowing with full film mulching, rain-collecting furrow sowing with ridge film, mechanized cultivation with furrow sowing on the side of plastic film and so on. In the areas with abundant heat and rich water resources, intercropping and interplanting techniques can be used to improve planting efficiency, such as flax interplanting sunflower, flax interplanting corn, flax interplanting vegetables and so on.

Fourth, strengthen field management and apply fertilizer scientifically. The fertilization of flax is mainly based on base fertilizer and supplemented by topdressing, according to the fertilization principle of "sufficient base fertilizer and early topdressing". The application of farm manure 1000-3000 mu of base fertilizer is best combined with deep application of autumn ploughing, 10 mu of urea and 50 mu of superphosphate, once as base fertilizer during soil preparation before sowing, and 5% diammonium phosphate or N-P-K multi-component compound fertilizer per mu. The topdressing of flax should be early, and it can be combined with the first irrigation at seedling stage or the application of urea per mu of natural rainfall to promote the growth and development of flax. Combined with soil preparation, chemical weeding soil closure treatment, 7-10 days before sowing; flax plant height 5-10 years, spray control of broad-leaved weeds and Gramineae weeds.

Fifth, mechanical planting to improve efficiency. Recommend machine harvesting to achieve full-process mechanized production, planter can use strip seeder; plain land, wheat combine harvester can be properly adjusted for flax harvest; small fields and slopes, small four-wheel tractors can be used to pull small-sized cutting machines to harvest, cut down and dry and grind them to improve harvest quality and efficiency.

Third, what are the effects and effects of flax?

1. Increase autoimmunity: rich in vitamin E, capture free radicals that destroy human cells, can prevent the destruction of cell membrane integrity, increase the number of antibodies.

two。 Removing lipids and reducing blood pressure: blood pressure is controlled, microcirculation is improved, capillaries are dilated, blood viscosity is reduced. Reduce blood lipids, prevent blood clotting, reduce blood viscosity, myocardial infarction, lower blood pressure, prevent stroke, pulmonary embolism and so on.

3. Reducing blood sugar and eliminating thirst: it has a certain role of adjuvant treatment for patients with diabetes.

4. Anti-cancer and anti-tumor: prevent the occurrence of cancer and reduce the incidence of canceration. Eliminate tumor, prevent and cure edema caused by cancer, cancer, etc. Clean up harmful substances in human blood, prevent and treat breast cancer, colon cancer, heart disease and so on.
