In the second quarter of China's Central Plains, the suitable growth period of spring potato is only 60-70 days. According to their fertility characteristics combined with current production practices, people have summarized the "three early mornings and three coincidences" efficient planting technology, which is suitable for reference and adoption in the northern regions.
Three mornings:
Choose early maturing varieties. Practice has proved that the selection of high-yield, high-quality, virus-free potato varieties within 70 days of emergence (harvest to harvest) is the key to achieving high yield, stable yield, and high-quality scale in spring potato. At present, the most ideal varieties are Holland No. 7, Holland No. 15, Zhengshu No. 6, etc.
Early germination. The use of Yangshuo for pre-emergence germination before sowing can make the emergence of potatoes early and homogeneous, seedlings full, strong seedlings, conducive to premature emergence of trees, early potato, is an important measure to increase production. The main points of germination techniques are: Seed potatoes are removed 25-30 days before planting, and each kilogram of seed potato is removed. Each kilogram of seed potato is cut into 40-50 pieces. Each piece must bear 1-2 middle and upper shoot roots. After cutting, dressing with plant ash to heal the knife edge. Then spread the seed blocks in Yangshuo, stack the thickness of 2-3 layers, cover 3-4 cm thick of clean wet sand, and then cover the film to warm the night and cover the straw to keep warm. When the shoots are 2-3 cm long, the shoots are picked out under scattered light for 3-5 days, making them green and strong, ready for sowing.
Short-term early broadcast. After the soil is thawed, watering, fertilizing, and soil preparation should be done as soon as possible to prepare for proper early sowing. In early March, when the temperature stabilizes through 7°C, it can be sowed. Should adopt ridging after filming, a film cover double row, large row spacing 70-80 cm, small row spacing 70-80 cm, small row spacing 30-40 cm, spacing 23-27 cm. After the sowing, a 5-8 cm high ridge was sprayed with herbicide and then covered with a plastic film.
Sanqiao:
Skillful fertilization. Early-maturing potatoes have a short growing period, and fertilization can be used to apply base fertilizer and seed fertilizer before sowing according to the requirements of soil fertility and yield, without having to top-dress. General Mushi composting chicken manure 1-2 tons, potassium sulfate 30-40 kilograms, urea 15 kilograms, diammonium phosphate 25-30 kilograms, organic fertilizer and 2/3 of the chemical fertilizer applied before tillage, in addition to its centralized Into the sowing ditch (note that the soil will be mixed).
How to water. Potatoes are crops that require more water, and ensuring sufficient water supply is an important condition for achieving high yields. Generally no watering is required before emergence. After the seedlings are planted, the first water can be visually sentimentally poured. After the plant buds, the underground stems begin to swell. After entering the peak of water demand, the water should be poured once every 7-10 days to promote rapid tuber enlargement.
Clever management. 15-20 days after sowing should be promptly broken membrane release seedlings, Qiao Miao to bud stage after treatment with aphids spray foliar fertilizer to protect seedling trees. Bud stage with 15% paclobutrazol 750 times spray to control the appetite to promote tuber enlargement. The main pests of early-maturing potato include aphids, red spider, and 28-spot ladybugs. It is possible to use high-efficiency, low-toxicity pesticides such as 10% imidacloprid 1000-fold, 20% erythrosine 1500-fold, etc. for prevention and treatment. Combined pest control can be mixed with potassium dihydrogen phosphate, fourer and other foliar fertilizer to promote high yield and quality.
