Potatoes are always indispensable on the table of every household. Looking at the time, it is time to plant potatoes. How can we make the harvest better? 1. Soil preparation and fertilization The soil should be fertile, the soil layer is deep, loose, and breathable (potato prefers loose soil, which is a necessary condition for high yield). The slightly acidic sandy loam soil should be smashed and deep ploughed before sowing, and the depth should be 20 cm. In combination with the mulch, the organic fertilizer is 2,000 kg/mu, and at the same time, according to the soil moisture, more than 20 kg of compound fertilizer (the ratio of nitrogen, phosphorus and potassium is 1:0.5:2). 2, seed potato treatment Select suitable fine varieties, and should carry out germination treatment, the seed potato can be spread under scattered light, keep 15-20 °C, directly spurt short buds, and then sow; apply turf and chlorothalonil before planting to add new height The lipid film is seeded, which promotes the healing of the cut knives as soon as possible, reduces rotten seeds, increases potassium, and prevents disease. 3, reasonable close planting Sowing at the right time, the new high-fat membrane insulation should be sprayed on the surface in time to prevent soil stagnation and increase the emergence rate. After emergence, the soil should be cultivated in time, and the soil should be weeded and loosened, and a small amount of soil should be cultivated to the roots. At the same time, it is combined with spraying new high-fat membrane to prevent infection of pathogens, improve the ability to resist natural disasters, increase the intensity of photosynthesis, and protect the growth of seedlings. 4. Field management It is timely to loosen the soil, cultivate the soil and ridge, and timely watering, cultivating and weeding, and rational fertilization. At the same time, the fruit should be sprayed before the flowering, the tuber formation period and the expansion period to effectively control the surface of the upper layer. Accelerate the rapid expansion of underground tubers, enhance the ability to resist pests, and ensure the high quality, efficient and good harvest of potatoes. 5, prevention and control of pests and diseases At the time of sowing or before the potato, 3-4 bottles/mu of phoxim, in addition to treating underground pests, and spraying with new high-fat film to improve the efficacy; at the same time for aphids, 28-star ladybugs, early blight, late blight, etc. Pests and diseases can be sprayed according to the requirements of plant protection to kill the drug, and the new high-fat film 800 times liquid is applied to consolidate the effect.

Beta carotene is the molecule that gives carrots their orange colour. It is part of a family of chemicals called the carotenoids, which are found in many fruit and vegetables, as well as some animal products such as egg yolks. Biologically, beta carotene is most important as the precursor of vitamin A. It also has anti-oxidant properties and may help in preventing cancer and other diseases.
Beta Carotene is also known as a provitamin because it can be converted in our body into vitamin A after oxidative cleavage by beta carotene 15, 150-dioxygenase. In plants, beta carotene, acts as an anti-oxidant and neutralizes singlet oxygen radicals formed during photosynthesis.

β- Carotene is a good nutritional supplement, we also have many good nutritional supplement series, conjugated sulfite, conjugated linoleic acid is one of the indispensable fatty acids for human and animals, but it is unable to synthesize a material with significant pharmacological effect and nutritional value, which is of great benefit to human health. Conjugated linoleic acid (CLA) has many physiological functions, such as anti-tumor, anti-oxidation, anti mutation, anti bacteria, reducing cholesterol, anti atherosclerosis, improving immunity, improving bone density, preventing diabetes and promoting growth. Folic acid, there are maternal folic acid and adult folic acid, maternal folic acid can prevent the lack of folic acid will lead to fetal spina bifida, anencephalia and other diseases. The main effect is to supplement folic acid for middle-aged and elderly people, quickly reduce Hcy level, and prevent cardiovascular and cerebrovascular accidents caused by high Hcy level. Lysine Powder mainly exists in animal food and beans, but lysine content in cereal food is very low. Lysine has positive nutritional significance in promoting human growth and development, enhancing body immunity, anti-virus, promoting fat oxidation, relieving anxiety and so on. At the same time, it can also promote the absorption of some nutrients, and cooperate with some nutrients to better play the physiological functions of various nutrients. In addition to these, there is vitamin D3.
