Rapeseed stiff seedlings can prevent and cure multiple symptoms
Due to poor drainage, the roots of rapeseed rot. Preventive measures: Open the three ditch in advance before planting, and do not plant it on rainy days. Apply the base fertilizer, and immediately after the live tree, raise the seedlings in succession, do a good job of cultivating loose soil, in order to facilitate ventilation, and promote long hair roots. In case of rain, it is necessary to clear the drains in time to prevent the water from damaging the roots. Dry and stiff seedlings transplanted rape in drylands and infertile lands, often resulting in the formation of seedlings due to the lack of water to affect fertilizer efficiency. Preventive measures: In case of drought during transplanting, timely watering and drought resistance, combined with the application of seedlings to promote growth. Transplanting low-temperature and stiff seedlings of rape was too late. The daily average temperature was below 10°C, and the ability to recover the roots was relatively weak. The growth of the aboveground parts was inhibited and red or yellow leafy seedlings appeared. Preventive measures: Pay attention to timely planting, such as postponing transplanting due to the late harvest of the previous crop, should adhere to fine soil preparation, apply seedbed fertilizer, select strong seedlings with soil transplant, and at the same time, cooperate with early application of seedling fertilizer to promote Early hair. Boron-deficient bounty mainly occurs in the soil where the soil is seriously depleted of boron, and drought or heavier drought or oil damage will affect the absorption of boron will also be lack of boron. Preventive measures: 2 to 3 days before transplanting, the seedbed per acre is sprayed once with 60 kg of a borax solution of 2%, and transplanted with boron to prevent the early lack of boron-free seedlings. Boron-depleted soil blocks are mixed with 500-750 grams of borax per acre for the application of base fertilizer during transplanting, or diluted with water after transplanting, and then soaked in water, and timely drought or drainage, promote root growth and absorb. If pests and diseases are severe after pests are transplanted, the locusts become infected and become infected with virus disease, causing the leaves to shrink and yellow. Preventive measures: 1 to 2 days before planting spray a medicine on the seedbed to prevent tapeworm transplanting. After the transplanting, the locusts must be sprayed and killed in time. Adding 500 times more food vinegar in the liquid mixture can increase the killing effect and resist the occurrence of viral diseases.
Omega-3 fatty acid is a long-chain, polyunsaturated fatty acid found in plants and marine organisms. Studies have shown that saturated fatty acids have adverse effects on health, while omega-3 fatty acids, as polyunsaturated fatty acids, have many health benefits. Different types of evidence suggest that the decrease of omega-3 fatty acid concentration can cause mood disorders. Some preliminary research results suggest that it can effectively treat a variety of mental disorders, such as bipolar disorder, schizophrenia and dementia. For pregnant and lactating women, it is a safe and effective treatment.
There are eight sources of omega-3: Antarctic krill, seals (seals), deep-sea fish, purple perilla seed, flaxseed, qiyazi (qiyazi), seaweed, South American oil vine and yak.
Fish / fish oil: it should be noted that only deep-sea fish are rich in omega-3. Unlike other three plant products, fish contain cholesterol. People with diabetes, hypertension and other diseases should consult a doctor before consuming fish oil to supplement omega3. In addition, fish is a common allergen, which will cause allergic reactions in many people, including children. If you are prone to allergic constitution before eating, please consult your doctor. Deep sea fish oil is rich in unsaturated fatty acids such as EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), which can significantly reduce cholesterol and soften blood vessels. Ruan Guangfeng, an expert of China food and nutrition information exchange center, said that EPA and DHA are the main components of fish oil that play a role in health care for the human body. They come from fish fat. The quality of fish oil is marked by the content of EPA and DHA.

Seaweed: the deep-sea rhynchophyta contains Omega-3. Some deep-sea fish ingest omega-3 because they prey on these algae. Because the existing methods of cultivating and extracting seaweed oil do great harm to the environment, it still needs some time to improve and improve in order to realize commercial production.
