Potato cultivation methods in shandong
The potatoes in shandong are planted in sheds early in april each year, and when the seedlings have grown to 2 inches in early may, they are replanted in the field and the early potatoes are harvested half a month before the end of june. Here's the potato planting method in shandong, which xiao jing has prepared for you。
Potato cultivation methods in shandong
1. Fields are prepared with straw to cover the cultivation of the potato, which should choose to be deep, fertilized, well drained and organically neutral or micro-acid rice fields. Rice pillars should not be too high or too low after harvesting, at 15-20 cm. The seeding is preceded by the opening of a ditch, the width of which is determined by the length of the straw and the quality of the drainage, usually at 1. 3 - 1. 5 m, the length of the ditch is 20 - 25 cm and the depth of the ditch is 15 cm. The dirt dug up when opening the ditch shall not be piled up along it, and shall be evenly thrown into the middle of the guillotine, which shall be formed in bow-back shape to facilitate drainage. Weeding is appropriate before seeding, but herbicides may not be applied。
2. Potato preparation
1 varieties selected. New varieties of potato are usually selected, which expand rapidly, have early potatoes, have short reproductive periods and are resistant to disease. For example, easton 303, medium potato 3, ksing iv, fiuri, etc。
2 chips slicing. Precipice is cut to save the seed and break the hibernation. The cassava seed of less than 40g, the cassava sprouts of more than 40g, ensure that each slice is around 30-40g, has more than one strong sprouts with more than 1 cm apart from an edifice, and is then impregnated for about 5 minutes with more than 50% of the filamentable powder and drying。
Three potato seed. Thrusts can be covered by hotbeds, greenhouses or thin membranes, and can be impregnated for 15 minutes with a solution of 85 per cent acinol 1 g with water of 100 kgg, followed by wet salvos, with a layer of potatoes that can be stacked up to three to four layers, which can hurt. Temperatures of 15-18°c are maintained during the sprouts, and the sprouts may be long; it is also inappropriate to water more water, wet the high and perishable potatoes, so that seeding can take place around 2 cm long。
Sowing
One seed time. It would be useful to sow the spring potatoes from mid-january to early february, and the autumn potatoes from late august。
Seeding and density. During seeding, the seeding is flat on the surface, and the seeding is down (up close to the ground) with a little pressure, so that the seeding is in full contact with the soil. General 1 m wide, 3 lines wide, 1. 4 m wide, 5 lines wide. 20 cm each of the two sides, with 500-5,500 units per acre。
Fertilizing. Potatoes have a shorter reproductive period and should be given a one-time application of base fat instead of fat. Each acre is decomposed 1,500-2000 kg of school fat, decomposed manure 500-700 kg and three-dollar composite particles 50-55 kg of base fat. They can also be applied to the seeding of potatoes, while compound fertilizer should be applied to the 5 cm range from the seeding of potatoes, so that they do not come into direct contact with the seeding of potatoes or are too close to them, in order to prevent poor seeding of potatoes。
5. Grass. As soon as the potato is ready, it is covered in a smooth and balanced manner (one acre of potato fields, approximately 3 acre of straw) and is covered in two directions, vertically with the acre, with about 1250 kg of straw per acre, with no gap, with a light and light stroke, generally with 10-12 cm thickness. It is too thick, not only to grow slowly, but also to grow softly; it is too thin and light-prone to increase green potato rates. When the straw cover is over, the dirt from the gutter is used to crush the straw at several points in order to prevent it from being swept by the wind。
6. Water management. Straw cover potatoes does not require fatting and weeding, but water management is required. In general, natural precipitation meets the requirements of this technology in general, but the drought of seedlings is due to low intake of fresh straw, slow absorption and easy drying. In particular, during periods when the chips are expanding, part of the ground is evaporating and the underground tubing is growing rapidly, when the greatest amount of water is required. Small water should be pumped into the gutter, the water should be slowly drained and dried in time, and soil moistification should be maintained in order to promote the growth of the tubing, while at the same time facilitating the decay of the straw。
7. Collect in due time. The harvest usually takes 60 to 70 days after the early harvest and can begin when the leaves are yellow. This method cultivates potatoes, with 70 per cent of the chips above the ground below the straw, which can be picked when harvested. The chips can either be collected once and in batches, with straw removed, large chips removed and then weededed, so that small chips can continue to grow, so that the best of the chips can be chosen, marketed in a timely manner, and yield high yields and economic benefits。
New technologies for the cultivation of potatoes are covered throughout the whole of the paddy crop. It facilitates the recovery of slurry, provides nutrients for potato production and provides good organic fertilizer for rice. Straw covers the cultivation of potatoes from the ground to harvest without the application of chemical herbicides and pesticides, and is a technique for the production of safe foods. The simpleness of the method, the economy of energy, the smooth surfaces of the chips, the colour of the chips, the low rate of deterioration and good commerciality is a practical light farming technique. It will facilitate the use of the land in winter, reduce winter run-off and increase farmers ' incomes。
Potato farming techniques
Cut the clot. Twenty days before the seeding began in early march. At least one eye for each piece of potatoes is cut. 10-15 bucks per pound. After cutting, water impregnation is sterilized with a small ash dried or polybacterial powder 1:200 times. The seedbed sprouts begin when the scavengers are dryed, and there are two methods: a salvo in the corner of the house above 15°c at room temperature, and a layer of sand; the second is to dig pits in the east-west direction of the outdoor ventilating sun, about 25 centimetres deep, with a layer of sand and a layer of seeding suitable for the third floor, then covered with an arctic film and at night with straw curtains. Both methods were sprayed one to two times during the sprouts to prevent drying. When the bud grows to 0. 5 to 1. 0 cm, seeding begins。
Full-scale ditch. In the event of a lack of affection, consideration should be given to the use of a gutter for the next 7 to 10 days. Potato cultivation is generally set for trenches, which can be opened with 50 centimetres in length and 40 centimetres in size。
Spread the lid. In particular, when spring is at its best, it should be mentioned that detoxification potatoes can be broadcast early, before the spring break is finished, and the distance can be controlled at 20 cm. The seeding is preceded by the spraying of 1,10,000 times more water in a ditch to prevent underground pests. Organic fertilizers can be released directly into a ditch or in the ground as a whole; chemical fertilizers can be moved into a ditch or between seed blocks (not to be in direct contact with seed blocks). There are two ways to plant the seed in the gutter: a sprout, which grows with strong roots and small but large potatoes, but two to three days later; the other method is to grow up, which produces relatively short potato roots, small but large potatoes, and seedlings two to three days early. At the end of the next plant, the earth will be taken from both sides of the main row, so that the space for the potato ditch and the small rows will be flatened and the microfilm lid will be compacted。
(d) shrimp and shrunk management. After light, around 20 days after seeding, there will be seedlings that will wash the microfilm out of the air to prevent evaporation. When the seedling grows to 10 cm high, the membrane around the seedling is compacted with soil to protect the water from the grass. Potatoes should not be watered in the pre-growth period, but only after the flowers. If the rain is dry, water can be poured every 10 days, usually twice or three times the water can mature and is stopped 10 days before the harvest. Insects such as aphids or parrots are protected from seeding。
