Time and method of cultivation of potatoes
Potato cultivation requires knowledge of the methods and timing of potato cultivation. The time and method of planting the potatoes you've made up, let's see。
Potato time
Potatoes, though cold crops, are not too early to grow, and some farmers in recent years have begun to grow before they are appalled. They are too early. They grow quickly. They are prone to cold and cold in the early spring. So once the seed season is frozen, the potato affects the entire season. As a result, planting time should not be premature, and the planting time for the field's spring potatoes should preferably take place after shock, before the spring break, at about 16 or 17 times in the history。
At minus 3-4°c, potatoes should be covered, such as sacks, old clothes, etc. At minus 6-7°c, it should be placed in a closed house and, in case of stronger cold air, a little bit of sheeting, thin film, which should be removed when the weather slows down. The temperature in the house where the potatoes are stored should not be too high, they must not be placed by the fireplace, the potato species are afraid of heat and cannot be warmer than 7 degrees. Too high a temperature can produce many buds, consume the nutrients of the potatoes, and later grow in the ground, which can lead to reduced yields. In short, potatoes are stored during the winter and the temperature is not less than zero in the house without covering it。
Potato cultivation
The method of seeding potatoes
Radio, applicable to arid hilly mountains. Elevation is applied to plots with sufficient humidity and a good base of fertility. The membrane cover is generally applied. Wide and narrow cultivation, applicable to high-water fertilized plots. Cotton intercropping。
Ploughing and ploughing on well-established land. It usually spreads through a ditch, usually 50 to 60 centimetres between the two sown ditches, where fertilized phosphorus or agrofertilizers can be applied to the seed ditches, where nitrogen fattening, such as ammonium carbon, can be spilled. And finally, it's covered。
(a) planting: on a leveled land, the seeding machine is adjusted by distance between the lines of the plant, the first is to cut the size of the block evenly and the second is to use the small whole potato, which is to open a ditch, seed and cover。
Scroll depth
The sowing depth should be based on soil quality and accompaniment. The soil is soaked deeper in conditions such as laxity and drought, and the earthy clay and wetland can be soaked as to be suitable for a depth of 9 to 10 centimetres. The arid zone should be soaked in depth of 12 to 15 centimetres。
Potato time
The duration is determined on the basis of local rainfall, temperature and sunlight. Tube formation is scheduled during the rainy season and at high temperatures (not exceeding 23°c)
Use of seedlings. In the event of spring and drought, rain is needed to sow。
Depending on how the species are grown. Early-mapping and re-planting should generally be done early and in due course. The medium- and late-literate varieties are broadcast late. The rainy season in shanxi province, which was mostly concentrated in july, august and september, allowed for the late broadcast of the tubers to be scheduled during the rainy season and to avoid excessive temperatures. In the case of the north-west of the mountain, the broadcast should be postponed from mid-april to mid-may。
It depends on the timing of the temperature and night cream. Ten centimetres of temperature is stable at 7-8°c and 20-30 days before the nightfall。
Depending on purpose and use. In the case of membrane protection for early marketing, two-season planting may take more than 10 days. In the middle and late season (i. E. Seedlings – about 105-120 days)
(1) a mid-september harvest should be planned and broadcast by mid-may。
(2) it is planned to be placed on the market in late august, with a broadcast due in late april. Cultivated in the north of the country for a season of more than 120 days (sprout-maturity) and with a duration of mid-april. Rebroadcasts of potatoes and large cabbage from the north basin and peri-urban areas were rebroadcast for 60 to 75 days, with large cabbage seeding in mid-july; the membranes were broadcast in early april. Land planting: the period of broadcasting is mid-april。
Potato disease prevention
Potatoes have night and early disease. Pathogenic bacteria are mainly found in the winter and summer seasons of potato chips with pathological potatoes and residues in soil. Potato-planted bacteria infestation with germs and larvae, forming a central strain of disease with disease, which, at low temperature and high humidity (at a temperature of 18°c-22°c and above 90% humidity), causes an intrusion from the air hole or skin of the strain. The disease falls from the wounds of the chips, the budding eye and the perforation of the skin, resulting in water immersion on the edges of the blades and the generation of brown clots in the tubers of varying lengths. If the leaves are not removed in a timely manner and the strain is removed, there will be 10 or 10 stories, resulting in the aching and death of a potato seed and the generation of brown or light purple dusts in one of the potatoes below the ground, which in turn will become non-commodative wastes with pink dry rotting or internal moist decay (deep brown or permutated potato skins of early disease and brown sponges under the skin). The main reason for the outbreak of the potato fever is the fact that the potato is treated as a “skin-throwing” crop, long-term succession, without seed disinfection, soil disinfection and subsequent failure to combat it in a timely manner。
“playing” potatoes also have its “personality”, i. E. They cannot be linked to long-term cultivation of potato and eggplant vegetables, requiring favourable conditions for disease prevention and treatment。
I. Selection of disease-resistant varieties and selection of healthy potatoes for disease-free fields
For example: "umong" in inner mongolia, "ksing" in heilongjiang, "big head" in beijing, "bumping into" a series of resistant varieties。
Ii. Seed disinfection
The first is thermo-impregnated seed: the potato is immersed for one minute in warm water at 40 °c - 50 °c and then in warm water at 60 °c (1:4 % potato and warm water). The second is drug impregnation: dry seeding in 15 minutes with %uplick or 70% glu (800 times fluid)。
Iii. Rotation
The epidemic is a common seed-and-earth disease of potato and eggplant crops, which is taboo. Reducing the source of the disease and mitigating its effects requires three to four years of rotation for non-immunicated crops, such as thorium, legume and lichen。
Soil decontamination
Potatoes and eggplant crops must be sowed with a strict soil disinfection. The method is to remove the leaves of the pre-cipested crop, to push the soil to more than 20 centimetres, to remove the residues of the crop and to reduce the pathogen. Each acre was sprayed with 20 kg ~ 30 kg of lime and 40 kg ~ 60 kg of grass-wood ash. After a rheumatism has been formed, a hole or ditch is planted on the roof and 40 per cent of the quintozene is planted around the potato with a protective soil of 90 kg ~ 150 kg dry soil。
V. Rational fertilization, science management
Both the bottom and the pursuit of fat must be applied rationally. Nitrogen, phosphorus and potassium are to be properly matched, organic fat is to be fully fertilized and potatoes are to be “eat well” and “eat healthy”. They are grown in time for planting, weeding, earth-breeding and the protection of the roots of the potato, which are not exposed or injured。
Drug control
When the conditions are right, the disease is rapid and dangerous and therefore subject to investigation. The leaves and strains were found to be immediately removed and destroyed and rapidly sprayed. In addition to fumi bi, daisenzi, bordeaux and mettobuzin, several pesticides are commonly used:
1. Prevention and control of night disease %pkli 800 times the fluid; 64% 毒 500 times the fluid; 47% ～ 600 ~ 800 times the fluid; 72% 克 600 times the fluid。
2. 50 per cent of anti-prevalence diseases are administered 1,000 times more frequently; 77 per cent kill 500 times more; 75 per cent clean 600 times more; and 64 per cent kill 500 times more. Every six to seven days, three to four times. We can't fight ma'annan mountain just once
