First, leave seed selection and land selection, all reserved potatoes should be harvested when the plants just bloom (in late April), select cool, ventilated, and attic flats after harvest to prevent snow falling on the Rat damage. Select high-quality seeds and use new high-fat membrane dressing to isolate pests and increase germination rate. Select the sandy land with flat terrain, convenient drainage and irrigation, loose fertile soil, and good permeability. Before, the field (ground) blocks that were not planted in Solanaceae or rice were best.
Second, the soil fertigation and arbitrarily planting shed for planting before the deep-turning land, Shizujifei, open good ditch, waist ditch and ditch between the ditch for the operation and irrigation. If you use the land planted in the original shed, use fresh lime to add a new high-fat film. The scaffolding material is mainly made from small bamboos. The width of the shed is 4.3~4.5m, the shed arc is 6.3m, and the height of the shed is 1.7~1.8m. Two squats are used in the shed, each squat width is 2cm in the shed and 35cm in the shed, and the shed is 70cm in length. The length of the shed is dependent on the size of the stalk. Generally, 30 to 45 sheds per 1hm2 are available.
Third, timely sowing, sowing date is January 24 to 28, the seeding rate per 1hm2 is 1800 ~ 2250kg, according to 1hm2 planting about 75000 standard dig live hole, the general spacing of 20 ~ 24cm, row spacing of about 60cm, digging slope. At the time of sowing, the potato species that has germinated about 7 cm will be placed in a diagonal position in the center of the hole, and the depth will depend on the length of the seed potato bud. After seeding into the hole, the seedlings are covered with nutrient soil, and the thickness of the cover soil is not suitable for sprouting. The new high-fat film is sprayed on the surface to insulate and protect the soil, prevent the soil from knotting, and increase the emergence rate.
Fourth, the management of fertilizer and water in the early stages of sowing until the emergence of ditch about 10d, to maintain the soil temperature and humidity within the shed, and promote seedlings early. When the seedlings are 70% or more fresh, they begin to cool off. Generally 10~15 days after sowing, they can produce seedlings. After emergence, select sunny shallow loose soil, cultivate soil to ridge, and timely watering, cultivating and weeding, and reasonable fertilization. The fruit must be sprayed once before the flowering of potatoes, during the tuber formation period and during the enlargement period, so as to effectively control the turbidity of the upper branches and leaves, accelerate the ultra-fast enlargement of the underground tubers, enhance the ability to resist insects, and ensure the quality and efficiency of the potatoes and the harvest. .
V. Prevention and control of plant diseases and insect pests, use of phoxim plus new high-fat membranes to treat underground pests before or after sowing. For the aphids, 28 ladybugs, early blight, late blight and other diseases and insect pests should be sprayed according to plant protection requirements of targeted agents for prevention and treatment, while spraying 800 times the new high-fat film to enhance efficacy.
