Potato farming techniques and management
Potatoes are the world's fourth-largest food crop, as well as a nutritious vegetable crop, containing a great deal of protein and minerals and vitamins, of which vitamin c, seven times the content of apples, duck pears and grapes, is popular. Here's the technique for the miller's choreography of the mountain and autumn potatoes。

Precipice planting is preceded by a deep, pine, plowing depth of 20 to 30 cm, and a 1 m perm perm perm perm per year in the main business, and the earth is broken and flatted。
The selection of good species and the timely planting of a small number of autumn potatoes for a period of approximately 120 days should be based on cooperation. 88 the best order for the fall potato cultivation is from late august to early september。
The cut-off is to be cut up to 40-50 grams a day before the seeding, with 1-2 budding chips, which, if cut to the sick potato, are to be immersed in 0. 5% potassium permanganate solution for several seconds. Slice and soot for disinfection. If the whole of the potato is sowed without disinfection。
(c) rationally sowned, fertilized and fertilized, with plant specifications: a range of 0. 3 x 0. 3 metres, with around 1,700 plants per acre. The sowing is usually 90-100 kg of potatoes per acre, depending on the size of the seed。
Autumn potatoes cover straw and are difficult to fatten and subject to the application of base weight. Organic fertilizers of 1000-1500 kg, 45% nitrogen, phosphorus, potassium three elements are generally applied to 40 kg compound, 40 kg per calcium or 40 kg per acoustic and 30 kg per phosphate. Organic fertilizer is distributed in seed belts of potatoes, and fertilizer is applied between potatoes, leaving the planting area about 5 cm. Upon seeding, we can use pig dung to catch fat or 5 kg urea, and generally not。
Straw cover covers the cultivation of acupuncture potatoes, usually 1. 5 kg of straw per acre of potatoes, with pre-prepared straw used to sow fertilizer the potatoes, with the tip of the straw evenly covered by 10 centimetres to the point of the grass, and with the dirt on the straw in the ditch。
Field management of potatoes is sensitive to moisture, which is characterized by a low number of prior periods, high levels of mashed potatoes and low levels of demand. Thus, when seeding occurs in the face of drought, water should be poured in time to keep the soil wet and the whole seedling guaranteed。
The main pests in the fight against potatoes are night disease; the main pests are tigers and moths, moths and yellow ants. Pest management is “preventive, integrated”, disease prevention and pest management。
1. Controls such as tigers, thorium, yellow ants and sowing acres with 3-4 kg of fentanyl particles or fine sand distributed in the sown ditch。
2. In the second half of the period, the main response to the terminal disease was 72. 2 per cent, using 1,000 times the prick, 72 per cent g lw 800 times or 25 per cent of the methadoxin, which was sprayed every 7 to 10 days, with four to five successive foliages, evenly applied。
The harvest is possible when the potato leaves turn yellow and the underlying leaves fall。
Autumn potato cultivation methods
Selection: autumn potatoes are grown from spring potatoes, and one or two are grown from spring potatoes without disease or pest。
(b) cropping: 1,500 kg of organic fertilizer in acres, with a microcropping machine for land reclamation. (c) to reduce labour intensity by opening up the land by 25 centimetres. Water when the ditch is completed。
Bottom fertilizer: urea, phosphorus, potassium. Of which 20 kg urea, 25 kg phosphorus and 25 kg potassium
The following species: a seed with a vertical distance of 35 cm on both sides of the ditch。
Land cover: soil cover of seeds, 7-10 cm depth, complete planting。
Water: after planting, water is poured every seven to ten days, three to four times。
Pine soil: once after seeding, the seedling is 15 to 20 cm high and 30 to 40 cm is now pine soil once。
Fertilizers: upon seeding, urea urea is distributed in pine acres at 15-20 cm height。
Harvest: the harvest can be achieved when the potato leaf is dried up, and labour costs can be reduced if suitable machinery is combined。
