Seedling management. During the emergence of seedlings, the seedlings and seeding holes are found to be misplaced. Seedlings should be placed in time to prevent burning of seedlings. After sowing, they will form a knot on the seeding holes. The knots should be broken in time to facilitate emergence of seedlings; Make up the seedlings and pull out the diseased seedlings.
Flowering and potato management. Before the flowering, flowering and potato-growing period management, the urea or ammonium bicarbonate is applied according to the growth. Topdressing depends on the sensation of the situation. When the drought is low, it is less likely to be chased or not chased. If the rain is good, the amount will increase. Potato is sensitive to trace elements of boron and zinc. In the flowering and potato-growing period, foliar application is carried out with borax, potassium dihydrogen phosphate and urea aqueous solution, and the plant ecological growth can be activated by spraying the fruit after the potato is applied. Positive energy, broaden the path of plant conduits, increase the water absorption and fertilizer absorption of plants, and improve fruit yield and quality. Usually spray once every 7 days, a total of 2-3 times. If the temperature is high during the potato-growing period, the potato grows weakly. When the ridge cannot be closed, the soil can be covered on the mulch to reduce the temperature in the ridge, creating a cool soil environment for the tuber to enlarge, so as to enlarge the tuber. Pest Control. The most common pests and diseases in potatoes are late blight and aphids and mites. After the occurrence of the disease, the drug should be used for prevention and control, and the prevention of pests and diseases should be done at the same time.

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.
