Problems solved by technology
[0003] However, in Heilongjiang, Xinjiang, the main planting areas of China, and most areas in the south where the development of flax is relatively late, the problem of lodging resistance of flax is common, which greatly affects the development of the flax industry.
In the late growth period of flax, the branches gradually increase, the fruit grows gradually and becomes heavier, the center of gravity of the whole plant moves upward, and it is prone to lodging under the action of wind and rain. Once flax lodging occurs, it is basically difficult to stand up again. Harvesting will not be possible, flaxseed yield will be reduced and the germination rate will be low, flax fiber quality will be greatly reduced, income can be reduced by more than 50% or even disappear
[0004] The best way to solve the problem of lodging resistance is to breed lodging-resistant varieties. However, due to the characteristics of flax itself and the limitation of genetic resources, no fine varieties with strong lodging resistance characteristics and suitable for planting in various places have been selected so far.

Embodiment 1
[0061] The method that present embodiment improves flax lodging resistance is as follows:
[0062] 1. The varieties with certain lodging resistance are preferred, such as Zhonglina No. 1, Zhongyama No. 2, Zhongyama No. 3, Zhongyama No. 4, etc.
[0063] 2. Sow flax in spring. After harvesting the last stubble crop, choose to turn over when the soil is dry after winter, and rake the broken soil after 15-20 days to reduce the occurrence of plant diseases and insect pests in the flax sown in spring; irrigate once 7-10 days before sowing, and use it directly Sow with a seeder, use 0.2% carbendazim seed dressing for flaxseed, and arrange the seed dressing time 2 weeks before the sowing date; if possible, sow early to prolong the growth time of flax at low temperature, low temperature and The longer physiological growth period is conducive to enhancing the ability of flax to resist lodging. Sowing can be carried out after the temperature continues to be higher than 4 degrees Celsius ...

The invention relates to the technical field of crop cultivation, in particular to a cultivation method for improving lodging-resistance capability of flax. The cultivation method comprises the following steps: irrigating a flax field 6 to 12 days before spring sowing, and sowing the flax in mode of deep groove and shallow covering, wherein the sowing density is 1,200 to 2,600 seeds / m<2>; applyingbase fertilizer after the flax is sown; hilling the roots of the flax in an elatocladus model period; applying potassium sulphate fertilizer in an early stage of rapid growth, and irrigating after the fertilizer is applied; and spraying a flower suppression agent in a flowering period. According to the cultivation method, the lignin content and the stem diameter of flax plants are comprehensivelyimproved and the gravity centres of the plants are reduced by regulating a sowing period and a sowing mode and regulating and controlling auxin, so that the lodging-resistance capability of flax is greatly improved.
Description
technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a cultivation method for improving the lodging resistance of flax. Background technique [0002] Flax fiber is of high quality, known as the queen of fiber, and is an important dual-purpose economic crop for oil and fiber in the world. Flaxseed is rich in nutrients, rich in linolenic acid, lignans, flax glue and other substances beneficial to the human body. Because of the high content of linolenic acid, cold-pressed linseed oil has a very good health care effect on the human body and is very popular in the market. Lignans have been proven to have a good effect on breast cancer, intestinal cancer, etc. Flax gum is a good dietary fiber, which has the functions of weight loss, beauty and nutrition and health care. It has certain effects in reducing the incidence of diabetes and coronary heart disease, preventing colon cancer and rectal cancer, and reducing the incidence ...
