Potatoes are a type of vegetable that many people like, and spring is the time when they grow. Don't miss it. How do you grow potatoes in the spring
First, the selection of good potatoes and the selection of good seeds is an important part of the high production of potatoes。
Ii. The seeding of potato slices 20 days before the seeding began in early march. At least one eye for each piece of potatoes is cut. $10-15 per pound is appropriate. After cutting, water impregnation is sterilized with a small ash dried or polybacterial powder 1:200 times. The seedbed sprouts begin when the remaining blocks are dryed, with two methods: a salvo in the corner of the house above 15°c at room temperature, with a layer of sand seeding; and a pit sprout in the direction of east and west of the outdoor ventilated sun, with a pit deep about 25 cm deep, a layer of sanded seedlings suitable for three floors, which are then covered with an accelerator film, which is kept warm at night. Both methods are sprayed 1-2 times during the sprouts to prevent drying. The seeding begins when the bud grows to 0. 5-1. 0 cm。
The land may be taken into account in the event of a lack of interest in the land。Potato cultivationGeologists are generally set up, with 50 centimetres in rows and 40 centimetres in rows. The expansion of the potato tubers requires a loose and fertile soil。
There are two ways to sow the lids when they are planted: the first is a bud-down, where the potato roots grow strong, small but large, but two to three days late, and the other is to grow a bud-up, where the potato roots grow relatively short, the potatoes are small but large, and the seed is 2 to 3 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。
5. Potato seeding and seeding management 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, normally two to three times the water can mature, and the water is stopped 10 days before the harvest. Insects such as aphids or parrots are protected from seeding。
• potatoes should be applied throughout the reproductive period on the principle of “pre-attack, mid-care, tail control” and once more when 80 per cent of the soil comes out of the seedlings, and the planting of ground fruit tiring begins during the potato seeding period, so as to make the underground nutrient transport catheter thicker, increase the vitality of the ground, smooth the face of the fruit, strong fruit and high quality production. Potatoes use farm fat, suitable for 4,000-5,000 pounds per acre, combined with nitrogen, phosphorus and potassium for appropriate fertilizer application. Potatoes require high amounts of potassium, with scientifically sound rates of 1. 85:2. 1 for nitrogen, phosphorus and potassium. Potatoes like to absorb ammonium nitrogen, and more sour。
In the latter stages of the potato period, which is mainly characterized by chronic diseases, frost and ailments, the disease is treated with a spray of 500 times the cathedral manganese zinc plus a new high lipid membrane during the drying of the clear open water, where it is discovered that the disease is to be removed from the ground and treated in a concentrated manner, as well as to be sprayed with lime or rooted with 0. 5 per cent of the ff solution in and around the disease, followed by the application of an agrococin chain 2,000 times the new high lipid membrane to prevent the spread of the disease。
