Problems solved by technology

[0003] The traditional planting of sweet potatoes is planted in one hole, with equal row spacing. This planting method has poor plant permeability, and the root growth of crops, surface water evaporation rate and night temperature distribution are all unfavorable to the growth of sweet potatoes, and pests and diseases will also cause Potato yields are low

Abstract

The invention relates to a green and pollution-free sweet potato cultivation method which includes the steps: (1) harrowing soil by the aid of a combined land preparation machine until the soil is soft and smooth, and mechanically spraying weed killer; (2) selecting improved varieties and strong seedlings: selecting sweet potato strong seedlings which is high in yield, resistant in close planting, high in disease resistance and free from insect damage; (3) implanting the improved varieties and strong seedlings into the soil, righting, enabling root systems to extend and to closely combine with the soil until the rhizomes of the seedlings are covered with soil; (4) seeding, then conveying water, and applying fertilizers; (5) laying a biodegradable mulch film on the soil planted with the improved varieties. A plurality of tiny holes are uniformly formed in the biodegradable mulch film, the diameter of each tiny hole ranges from 1nm to 20nm, the cultivation mode is simple to operate, green, environmentally friendly and free from pollution, and the yield of sweet potatoes is improved.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a green and pollution-free sweet potato cultivation method. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato, yam, etc., people in different regions call it differently. People in Shandong call it sweet potato, people in Sichuan call it sweet potato, people in Beijing call it sweet potato, and people in Fujian call it sweet potato. Sweet potatoes are rich in sugar, protein, cellulose and a variety of vitamins, especially β-carotene, vitamin E and vitamin C. In particular, sweet potatoes are rich in lysine, while rice and flour lack lysine. Eat sweet potatoes mixed with rice noodles, you can get a more comprehensive protein supplement. In terms of overall nutrition, sweet potatoes can be said to be the best among grains and vegetables. Europeans and Americans praise it as "the second bread", former Soviet scientists say...
