The city has now included the cultivation and development of fall potatoes in the way of increasing the incomes of farmers, and the active exploration of the excellent techniques of autumn potatoes has become a necessary route to higher economic and planting benefits. The selection of excellent varieties, seedlings, drug-infested seeding of potato seed prior to seeding, seeding of whole potatoes, cloud seeding and, where appropriate, high-intensity cultivation are excellent techniques for increasing the yield and survival of autumn potatoes。
1 choice of the autumn potato species
Autumn potatoes, because of their abundant light and relatively high temperatures, are suitable for the selection of smaller and pre-maturized chips. The climate in the city is mixed, and the suitable varieties are faureta, potato 2. As a pre-literate species introduced from the netherlands into our country at an early stage, the birth cycle ranges from 60 to 70 days, with an average of 60 cm tall, well-planted and standing, small branches, pollen-rich, and anti-y and curly viruses. The tubers are well coloured, with a long elliptical light yellow, a darker skin color, a lightly lumbered surface, short hibernation, a single 2000kg/acre, and a high production of 3,000 kg/acre. Faurel has a high vitaminc content and a better taste for export, which is a good cash crop and planting option. Potato 2 is a medium- and late-literate species suitable for planting in the highlands. In the 80-90-day fertility cycle, potato 2 has an average of 79. 5 cm high, a straight and strong plant, a rim shape with a round, a yellow skin colour, a full tuber, a high protein content and a high dry substance content, with a better survival and commercial ratio. In order to reduce pests and diseases and increase production and economic efficiency, potatoes should be selected for non-virus detoxification, with high or multiple production potential。
2 potato processing in autumn
Autumn potatoes must be sprung, and appropriate drug impregnation seedlings are required for dormant potatoes before sowing. Leaching seedlings are selected for leaching with cactin. Acin is an efficient plant growth regulator that can quickly break the hibernation of potatoes. A small amount of alcohol or highly white wine is mixed with cactin before impregnation, which is dissolved and diluted with water to the appropriate seed concentration of 8 mg/l. Achromic impregnation takes place about 10 days before seeding, with 15-20min leaching. At the end of the leaching, the potato is taken out for dry-laying sprouts, the size of the chips is about 20 cm thick, the above and the surroundings are covered with wet sand soil and water is prohibited during the sprouts. The ventilator is humid in the environment for a period of 7-9 days, and the sprouts grow around 2 cm to remove the chips and sow them two days later in the sun。
Concentrations of acin solutions are strictly controlled during the sprouts, with low or high concentrations affecting potato production. In the configuration of the acinol solution, it should be readily available and not overnight. The thickness of seeding is not appropriate, and soil moisture is properly controlled to avoid the presence of bad potatoes。
3 autumn seeding of potatoes
The fields where the potato is grown in the autumn are suitable for the sandy soil, which is deep, fertile, air-transmitting and drought-resistant. As a result of the high temperatures and heavy rains of august, the planting of potatoes in the autumn is highly susceptible to death. The sowing of whole potatoes can be effective in avoiding such phenomena and in increasing the production of potatoes. In the case of seeding of potatoes, it is too early or affected by the high temperature of the “autumn tigers”, which results in poor production and poor quality of potatoes, as well as serious seed deficiency and disease. The late seeding of potatoes leads to early frosting of potatoes and slow growth and small growth of potatoes as a result of freezing, as well as low yields. Taken together, the potato seeding in our city is suitable between 30 august and 5 september. Because of the short birth cycle of potatoes, the process of fertilization should be dominated by the use of base fat, supported by the pursuit of fat. Early application in pursuit of fertilisation, re-application of base fertilisation, combining organic and fertilizer. In order to ensure the survival of the potato, it is desirable to plant it in the dark and to avoid the heat of the noon season. Autumn potatoes should be grown with a proper increase in the density of reasonably dense seedlings, with small strips growing and luminous。
4 autumn potato field management
Autumn potatoes need to be grown in pursuit of fattening, with the upper leaves of the front potato fields growing mainly, and enhanced management of fatty water can contribute to the growth of potatoes leaves and lay the foundation for later light cooperation and nutrients. Urea should be used for the first fat hunt once the seedlings are ready. In the latter part of the fall potato crop, the leaves grow slowly, the potatoes start to grow reproductively and the chips start to swell. Nitrogen fertilizer should be used to support the cultivation of soil and the proper spraying of potassium phosphorus on the leaves. Potatoes are then required to cultivate the soil and soak the weeds in order to promote the growth of the seedlings. It's 25 cm or so long, and then we'll have a second plow, a plow. In the early stages of the flowering, the soil is grown twice, three times before the frost falls, and the layer is thick enough to ensure that the chips are not frozen. In order to ensure potato production, the expansion of potato chips could be prolonged and the harvest could be delayed, as appropriate, to increase the incomes of farmers。
5 autumn potato pest control
In the autumn, which is characterized by heavy rainfall, it is a high stage of ailments and plagues, which, if discovered, must be removed and destroyed in a timely manner before being treated with agro-chainicillin. Potato disease requires a timely observation of the time to prevent and treat it, and during seeding or seeding periods, the soil is to be ploughed with dyson manganese zinc pesticide and applied to the root of the potato. Potatoes form a long-term, medium-term later stage, and if a strain is found, the leaf must be removed and treated with a mercantile zinc spray twice at intervals of 7-10 days. For highly infested areas, the use of insecticide-proofing pesticides, such as ephemerals, will require scientific application to the gutter. In the case of land, such as tigers or yellow ants, there is a need to spray or root with thiophos-methyl cream, and toxic soil can also be sprayed at root。
These are the main elements of the technology used to grow potatoes in the autumn of the city, which can be read more and learned more from the experience of the region。
