Hot Pepper Cultivation Techniques in Winter

The protective cultivation of peppers in winter is the use of a greenhouse or greenhouse sheds, grass sheds above the grass, planting in the winter before the winter flowering results, a method of cultivation listed in early spring. It is also the most technologically advanced and most difficult cultivation method. The technical points are summarized as follows:

First, the varieties of peppers and bell peppers that are selected for winter cultivation are suitable for early-maturing or medium-maturing varieties, and the fruits of late-maturing varieties are slow to grow and should not be used. When choosing, pay attention to the varieties used must be resistant to low temperature and low light, especially in the case of short sunshine, poor illumination, and low temperature, normal differentiation of leaf buds and flower buds can be achieved. The fruit that is formed is seeded fruit and can normally expand. Some varieties grow well in other ways, but they may not be able to tolerate low temperature and low light during the winter season, and the buds and flower buds are not normal. In early spring, the flowers that are opened are often abnormal flowers, and the resulting fruits are seedless. If you can't grow up. Therefore, the development of winter-cultivated varieties must be successful after more than one year of trial planting, and blind promotion of unknown varieties is not allowed.

At present, in Shandong Shouguang and Cangshan, “Hangjiao Guanlong”, “Longjiang”, and “Hangjiao Jade Dragon” are selected. According to observations, these varieties are not only resistant, precocious, but also relatively resistant to low temperatures and weak light. After winter, the flowering can be normal, and the result is much. The fruit enlarges quickly and the yield in the middle and early period is high. After condolence, it can also produce good results in the later period, and it is popular among vegetable farmers.

Second, the seedlings winter pepper breeding period in late September to early November, when the temperature is still high, easy seedlings, seedlings grow faster. It can be sowed with nutrient clods after sowing of bed soil or even sowing. The seeds can be immersed in warm water to kill the germs on the seeds, dried and sown without germination. After emergence, we should pull grass in time and sprinkle dry fine soil. Pay attention to ventilation and prevent leggy.

Third, planting should be 20 to 30 days in advance to deepen the sunburn. Before the planting, apply the base fertilizer, especially the fully decomposed organic fertilizer and nitrogen, phosphorus, and potassium compound fertilizers. After the application, plow the soil with a rotary plough to dilute the excreta and then rid it. The suitable planting period is before and after the snow, when the temperature is still high, it is easy to grow roots after planting. During the colonization, the small ridges were planted in a row of 67 cm from the solar greenhouses. The ridges were planted in a single row and a mulch was applied to every two ridges (when watering in winter, the mulch can be watered under the mulch to prevent high humidity in the shed). Plant spacing is 33 cm, and 667 square meters (1 mu) are planted with 3000 plants. Use the greenhouse under the shed, and in the two halves of the greenhouse, make a hoe each and plant 4 to 6 rows of pepper seedlings in the oysters. Variety can choose to use small plant type "Sujia No. 5", spacing 40 cm, spacing 30 cm, after planting each side deducted a small shed, at night in a small shed stamped grass.

Fourth, field management The entire winter should be mainly cold insulation, vents should be small, ventilation time should be short. In winter, watering should be strictly controlled to prevent the occurrence of diseases due to high humidity in the shed. On the basis of applying base fertilizer, 0.5% urea and 0.3% potassium dihydrogen phosphate solution can be used for extra-root fertilizer. When necessary, 350 times the rice vinegar water, 100 times the sugar water, 200 times the urine, 700 times the zinc sulfate water mixture, supplement the plant nutrition. In case of pests and diseases, it is necessary to spray pesticides in time. Before and after the beginning of spring, the temperature began to rise, and some plants had already set fruit. It was necessary to pay attention to timely watering, topdressing, and promoting fruit growth. In addition, lifting ropes should be used to lift the main branch of the fruit to facilitate the result. After entering March, the temperature rises, the plant grows and develops vigorously, and begins to produce a large number of results. At this time, it is necessary to increase the release of wind, prevent leggy, and pay attention to top dressing and watering, so that the development of the tree and the results will be carried out at the same time.

V. The market price for harvesting early winter peppers is quite high, and attention must be paid to early harvest. When harvesting, we must pay attention to the timely removal of some of the seedless deformed fruit, to avoid falling. Combined with harvesting, appropriate top dressing and watering, the peppers produce a large number of results under the appropriate conditions in spring.

Anti-Cardiovascular

Cardiovascular disease is a serious threat to human, It is a common healthy disease especially in the elderly over the age of 50, even if used the most advanced treatment, there is still have more than 50% of cerebrovascular accident survivors can not completely self-care, The world's annual deaths from the disease as high as 15 million people, ranking the first cause of death. Cardiovascular disease is the number one disease that threatens human health. Currently anti-cardiovascular disease drugs mainly include cardiac drugs, anti-angina drugs anti-heart rate disorders drugs, antihypertensive drugs, anti-hyperlipoproteinemia drugs. Drug therapy is only a means of prevention, The fundamental is prevent from the source. Cardiovascular disease, in addition to being affected by genetic factors, mainly is associated with unhealthy lifestyles. Also known as lifestyle sickness. So the establishment of a healthy and reasonable way of life is the key to prevention.
