Abstract
The invention discloses a method for frost-proof cultivation of autumn potatoes by covering plastic films. The method comprises the following steps: (A) ploughing and carrying out full-thickness soil breaking, wherein the ploughing depth is about 15cm; (B) furrowing, wherein the furrow surface is 120cm wide and the furrow ditch is 40cm wide; (C) punching holes, wherein the holes are 8cm deep and the distance between row and hill is 40*35cm, and four thousand seven hundred sixty two holes are punched each Mu; (4) applying a base fertilizer; (E) seeding; (F) earthing, wherein the potato seed earthing layer is 8cm; (G) covering plastic films for preventing frost; (H) managing, to be specific, carrying out daily management including application and promotion of fine seeds, sprouting, sowing and the like.
Description
Technical field
The present invention relates to the methods of cultivation of potato frost protection, relate in particular to the methods of cultivation that potato planted in autumn covers plastic film frost protection.
Background technology
The happiness of potato property cools, and is afraid of frost, avoids half hot cold-resistant crop, and preference temperature is grown in the environment of 15-20 ℃, suitable spring of south China, Qiu Erji cultivation.In The Middle And Lower Reaches in two sides, the Changjiang river, long autumn in summer is short.Avoid hot potato and will arrive about September 10 sowing, frost sooner or later, determines the length in potato planted in autumn vegetative period and the height of per unit area yield for the first time.
At present, the potato planted in autumn methods of cultivation, specifically comprise the following steps.
1, plough soil tilling depth 15cm left and right, holostrome hack.
2, do furrow, furrow face width 120cm, furrow furrow width 40cm, leveling furrow face.
3, beat cave, the dark 8cm in cave, furrow face distance between rows and hills 30 * 35cm, furrow ditch is at the average 40 * 35cm of interior distance between rows and hills, every mu of 4762 caves.
4, base manure, composite chemical fertilizer is executed in cave, the potato seed of semi supplied manure lid.
5, sowing, before potato seed is put in cave, hugs chemical fertilizer on one side, prevents from hindering potato seedling.
6, earthing, furrow ditch arrives clearly 15cm under the face of field, leveling furrow face, potato seed overburden layer 8cm.
7, management, application breeding, the technology such as vernalization sowing, carry out cultivation and banking, impose fertilizer, prevent and treat the daily managements such as disease pest and weed.
, there is following defect in the above-mentioned potato planted in autumn methods of cultivation.
Frost protection not, potato overground part because of first frost withered, vegetative period short yielding poorly.
The object of the invention is in order to overcome not frost protection of potato planted in autumn, vegetative period is short, the defect yielding poorly.Before frost, directly on potato planted in autumn plant, cover plastic film, save frame, simple and convenient, kept away first frost.After utilizing first frost, the fine temperature recovery of weather is fast, and the climatic resources of " little spring in October " extends the vegetative period of potato planted in autumn, thereby improves quality and per unit area yield, provides a kind of potato planted in autumn to cover the methods of cultivation of plastic film frost protection.
The object of the present invention is achieved like this: a kind of potato planted in autumn covers the plastic film frost protection methods of cultivation, specifically comprises the following steps.
A) plough, soil tilling depth 15cm left and right, holostrome hack.
B) do furrow, furrow face width 120cm, furrow furrow width 40cm, leveling furrow face.
C) beat cave, the dark 8cm in cave, furrow face distance between rows and hills 30 * 35cm, furrow ditch is at the average 40 * 35cm of interior distance between rows and hills, every mu of 4762 caves.
D) base manure, composite chemical fertilizer is executed in cave, the potato seed of semi supplied manure lid.
E) sowing, before potato seed is placed in cave, hugs chemical fertilizer on one side, prevents from hindering potato seedling.
F) earthing, furrow ditch arrives clearly 15cm under the face of field, leveling furrow face, potato seed overburden layer 8cm.
G) overlay film, cold wave is attacked before the weather of first frost, and plastic film is directly overlayed on potato planted in autumn plant, and surrounding prevents that with soil block compacting plastic film is blown up.
H) management, application breeding, the technology such as vernalization sowing, carry out cultivation and banking, impose fertilizer, prevent and treat the daily managements such as disease pest and weed.
Owing to having adopted technique scheme, potato planted in autumn covers the methods of cultivation of plastic film frost protection, plastic film directly covers on potato plant, simple and convenient getting twice the result with half the effort, environment for potato creation frost protection, after cold wave frost, weather is fine for the first time, sunny temperature gos up fast, potato energy normal growth in plastic film, after 2-3 cold wave frost, outside air temperature is more and more lower, potato in plastic film starts withered and yellow, kept away cold wave frost 2-3 time, potato can extend growth about 15-20 days, improve the output of potato, 1500 kilograms of left and right of per unit area yield, mu amplification reaches 20%.The present invention has realized potato planted in autumn high and stable yields, and economic, social, Ecological Effect Yidu is improved.
Embodiment
Below in conjunction with embodiment, the invention will be further described.
