What should be noted for high-yield potato planting? Netizens with potato growing experience are kindly asked to give a detailed introductionPotato, commonly known as yam egg, is a crop used as both vegetable, grain and feed. To achieve high yield in potato planting, it is necessary to select excellent varieties, suitable cultivation methods, balanced fertilization and strengthened management. Therefore, Zhongdi Network has compiled the key points to note when planting potatoes, listed in detail below for netizens' reference.
I. Selection of planting land and land preparation:
For potato planting, sandy loam soil with deep, loose and fertile soil layers should be selected, and early autumn deep plowing should be carried out, with deep plowing of 7-8 cun. This can not only eliminate weeds, reduce disease and pest damage, store more natural precipitation, but also facilitate potato root development and the formation and expansion of tubers.
II. Treatment of seed potatoes:
Potato seed potatoes should be taken out of the cellar 15-20 days before sowing, and sprouted under the condition of maintaining 15-18 degrees in the cellar. After 10-15 days, when most of the buds on the seed potatoes have sprouted to the size of a match head, put them outdoors in a leeward and sunny place for sunning, generally for 7 days.
III. Potato sowing time and density:
Start sowing when the ground temperature reaches 8-10 degrees. For late-maturing varieties, about 4000 plants per mu; for early-maturing varieties, about 4500 plants per mu. If mainly for commercial potato production, the corresponding number of plants per mu should be smaller; if mainly for seed potato sales, the number of plants per mu should be appropriately larger.
IV. Fertilization of potatoes:
When sowing, apply high-quality farmyard manure in furrows or holes at more than 3000 kg per mu, and deeply apply 25-50 kg of compound fertilizer as base fertilizer. Do not let it contact the seed potatoes to prevent burning the seed potatoes and affecting emergence.
V. Management of potatoes during the flowering period:
During the bud stage and full flowering stage, inspections must be carried out twice. If degenerated and mixed plants are found, they must be pulled out together with the tubers and deeply buried to prevent viral disease infection, which can lead to aging, so as to ensure seed potato quality and high-quality seed potatoes.
