Sweet potato efficiently, gently simplifies covering cultivation method
Technical field
The present invention relates to a kind of sweet potatoes cultivation method, belong to cultivation method technical field.
Background technology
China is sweet potato producing country the biggest in the world, and cultivated area and gross yield account for 60% and 85% of the world respectively.The long-term cultivated area of current China sweet potato, more than 5,500,000 hectares, is only second to paddy rice, wheat and maize, and gross yield reaches 1.5 hundred million tons, for national food security plays positive role.China sweet potato is multiple is implanted in hills unfertile land, monolithic land area is less, sweet potato concentrates producing region mostly to be terrace shaped soil, this just causes sweet potato to carry out big machineryization cultivation is unpractical, moreover, current sweet potato is planted many employings and covers transparent mulch film, and existence is taken a lot of work difficultly, herbicide spraying exists pollution and namely can not produce pollution-free food, affects the problems such as potato seedling growth.
Current China sweet potato produces in cultivation, mainly adopts traditional plastic-film-covered cultivation technology, and program is: ridging, to plant sweet potato seedling, water nest water, envelope nest, face, ridge spraying herbicide with hand.Cover transparent mulch film, ticked by potato seedling, with around soil pressure young plant, need 8 steps altogether, program is loaded down with trivial details, take a lot of work hard, mu needs labour 5-6 people.
Summary of the invention
The object of the invention is to solve the deficiency that above-mentioned prior art exists, provide a kind of step simple, save labor, free of contamination sweet potatoes cultivation method simultaneously.
Sweet potato efficiently, gently simplifies covering cultivation method, it is characterized in that comprising the following steps:
(1), ridging: ridging, row spacing is 75-85cm;
(2), cover black mulch film: adopt artificial or mechanical means by black film mulching in the 1st step on the ridge of rising;
(3), punching waters: to be watered membrane-repturing device by sweet potato growing punching between ridge, punches in the ridge having covered black mulch film and water in the 2nd step;
(4), seedlings plugging: by seedlings plugging rod seedlings plugging;
(5), buried via hole: after in sweet potato seedling inserting hole, with a little soil, whole port lid is lived, complete sweet potato growing overall process.
Step (3), punching are watered: punching pitch-row is 20-25cm.
Step (3), punching are watered: the punch membrane-repturing device that waters of described sweet potato growing is a kind of punching and the synchronous utensil that waters, and once can beat 5-15 hole.
Step (4), seedlings plugging: seedlings plugging rod is the rod that one section of one end is made into concave arc, other end dome (preventing from grinding hand), is stuck in circular arc in use, is then inserted in the hole sweet potato seedling by sweet potato seedling.
Described black mulch film is the effect mulch film with natural suppression weeds.
Black film mulching, sweet potato growing punching watered membrane-repturing device, sweet potato seedlings plugging rod of the present invention is applied to sweet potato and covers in cultivation, and the program of being planted by sweet potatoes reduces to 5 steps by 8 steps, simplifies sweet potato cultivation operation sequence, reduces labour intensity; Black film mulching, because black mulch film has the effect of natural suppression weeds, does not need herbicide spraying, has both decreased the pollution that working feature turn avoid weed killer herbicide, is conducive to producing pollution-free food; Sweet potato growing punching water membrane-repturing device punching with water synchronous, there is flexible, the easy to operate advantage of use; Sweet potato seedlings plugging rod avoids by the direct seedlings plugging of hand, reduces labour intensity, and circular arc can protect sweet potato seedling to preserve from, and easy to operate, cost is lower, easy to make.

Embodiment
Below provide the specific embodiment of the present invention, be used for being further described formation of the present invention.
Sweet potato efficiently, gently simplifies covering cultivation method, comprises the following steps:
(1), ridging: ridging, row spacing is 75-85cm;
(2), cover black mulch film: adopt artificial or mechanical means by black film mulching in the 1st step on the ridge of rising;
(3), punching waters: to be watered membrane-repturing device by sweet potato growing punching between ridge, punches in the ridge having covered black mulch film and water in the 2nd step;
(4), seedlings plugging: by seedlings plugging rod seedlings plugging;
(5), buried via hole: after in sweet potato seedling inserting hole, with a little soil, whole port lid is lived, complete sweet potato growing overall process.
Step (3), punching are watered: punching pitch-row is 20-25cm.
Step (3), punching are watered: the punch membrane-repturing device that waters of described sweet potato growing is a kind of punching and the synchronous utensil that waters, and once can beat 5-15 hole.
Step (4), seedlings plugging: seedlings plugging rod is the rod that one section of one end is made into concave arc, other end dome (preventing from grinding hand), is stuck in circular arc in use, is then inserted in the hole sweet potato seedling by sweet potato seedling.
Described black mulch film is the effect mulch film with natural suppression weeds.
Black film mulching, sweet potato growing punching watered membrane-repturing device, sweet potato seedlings plugging rod of the present invention is applied to sweet potato and covers in cultivation, and the program of being planted by sweet potatoes reduces to 5 steps by 8 steps, simplifies sweet potato cultivation operation sequence, reduces labour intensity; Black film mulching, because black mulch film has the effect of natural suppression weeds, does not need herbicide spraying, has both decreased the pollution that working feature turn avoid weed killer herbicide, is conducive to producing pollution-free food; Sweet potato growing punching water membrane-repturing device punching with water synchronous, there is flexible, the easy to operate advantage of use; Sweet potato seedlings plugging rod avoids by the direct seedlings plugging of hand, reduces labour intensity, and circular arc can protect sweet potato seedling to preserve from, and easy to operate, cost is lower, easy to make.
