Page 7 - high-yielding potato production is a potato vegetable, known as tara, eggs, potatoes, etc. The potatoes have a variety of skin colours, such as white, milk yellow, red purple, etc.; the potatoes have white, purple, yellow, red and purple skin colours; and their total production is third after rice and wheat worldwide. Why can't local and southern potatoes grow? (the causes of degradation are three schools of learning) a: the first is mainly the presence of strains and roots caused by viral infestation, and the widespread spread of aphids, mainly with the appearance of flowers, curls and beads, making the selection of resistant and resistant varieties, such as detoxification potatoes, which is now widespread. B: the second is the effects of temperature, caused by tissue aging during growth and storage by high temperatures, and the physiological processes in the potato are damaged by the intense effects of high temperatures, mainly increased oxidation, so that growth begins to stop and individual tissues and organs die. At low temperatures, seeding can prevent the rate of degradation. C: the third is the aging doctrine, with the long-term use of non-sexual reproduction, which leads to poor caste ageing and degradation of castes, which can be carried to the next generation through spas. Why is the seed degradation of potatoes not eliminated? Because the lower part of the plant is growing at all times, some of it matures and has a natural rejuvenation. Overall, the degradation of potatoes is caused by a combination of factors, internal and external to the resistance of varieties and indirect to the effects of environments such as high temperatures. The environmental conditions that affect the growth of potatoes are a: temperature: potato-cooled climates can take root at 4-5°c, seeding can begin to take root at 5-7°c, seeding at 10-12°c and growing quickly and robustly at the best at 18°c, mr. Rooting when seeding at low temperatures, and sprouts after rooting at high temperatures, with leaves growing at around 20°c most appropriate, and a stem almost stopped growing at more than 25°c, and a stem stopped growing at around 30°c. B. Nutrients: fertilization patterns: n:p:k = 6:09 for seedlings, with the greatest amount of fattening from seeding to potato season, n:p:k = 38:36:36,56:48:55. Experiments at the provincial agricultural institute summarised the theory of the need for fattening: n:p:k:2:1:5. C; soil conditions: it is best not to be connected, to be rotated as much as possible, and to be careful not to be associated with eggplant vegetables (e. G., peppers, tomatoes). Potato pickles? When the potato sprouted, it grew more than 3 cm long, it took its roots from the base of the sprouts, and it later took root in sections of the earth that had not been buried under it. The roots are in the 33 cm layer. Individually, 1 - 2 metres of soil is available, with the most rapid expansion of the plume during the flowering period of 10 days, at which time about 50 per cent of the production takes place. Potato cultivation techniques selection and seed treatment: locally, due to growth constraints, pre-maturated, high-quality, disease-resistant, high-yielding detoxification varieties such as chinese potato number three (65 days, 55-60 cm), fauria (60 days, 50 cm), zheng potato number 6 (60-70 days, 60 cm), kranoi no. 1 (80 days, 50 cm), morning white (60-65 days, 70 cm), east african farmer number 303 (more, smaller, quickly phased out). In order to save seeds and to grow early, potato seeding can be cut, with a “horizontal” cut to the “triangular” block, with the cut coming close to the eye, with the cut having a weight of not less than 20 g each, and a normal 30-50 g, requiring 1-2 budding. General acres are grown 120-150 kg. Circumcinosis and intoxication can be transmitted with a cutter, so the cutter is strictly sterilized, 75 per cent alcohol, or 2-3 per cent to the sole, and 0. 01 per cent potassium permanganate. To promote gerontization, the cut should be close to the budding eye, typically 2 mm. - soil treatment. Before seeding, 50% of octhion cream per acre can be used from 100 to 200 grams, or 80% of dichlorvos cream from 100 grams, made into slag particles from 15 to 20 kilograms, scattered over the surface and immediately ploughed deep. Potatoes require more potassium, less nitrogen and less phosphorus. We use pre-year membrane cover cultivation, more fertilizing by “one shell” fertilisation; note that in fertilizer selection, potassium or compound fertilizer must be free of chlorine ion, i. E., none of the chlorine-containing ion fertilizers, as potatoes are anti-chlorine crops; the choice of potassium sulphate fertilizer or composite fertilizer made of potassium sulphate can be used, with large sulfide double-cropping (dry control, temperature protection, fattening), with a width of over 60 cm and a ditch of 30 cm, which is conducive to temperature and protection. Forty-five per cent of potassium sulphate compound fattens 50 kg per acre with 5 kg of urea and 10 kg of potassium sulphate. Seeding and planting time: due to the growth season and time constraints, it should be broadcast early in time, usually about 45 days before the terminal frost (the local terminal frost is around 5 april, the membrane cover is usually in late january and early february, and the membrane cover + small bow shed planting is pushed 50 to 60 days before the final frost). The potato, even when endangered by nightfall frost, is able to recover and mature its troughs sufficiently in the run-up to summer heat. Due to the low temperatures at the time, the potatoes were rooting and sprouts, and the roots were well-established when the soil was released, so that they could grow rapidly and early. The unprocessed seeding of potatoes is more timely and early than seedling. The planting of seeds can be done in a downward spiral, but not too deep. Iv. Weeding techniques for potatoes (1)
