Embodiment Construction

[0009] Such as figure 1 Shown is a high-yield cultivation method for autumn potatoes covered with plastic film. Corn is sown in mid-May. Corn is selected from early-maturing varieties and planted in wide and narrow rows with a large row spacing of 90 cm and a small row spacing of 40 cm; Seed potatoes for 10 minutes, dry them slightly and stack them in a cool place to germinate; in mid-August, sow autumn potatoes between large rows of corn, and open a sowing ditch with a depth of 3-5 cm at a distance of 12 cm from the corn row. Open 2 ditches between the rows, the distance between the potato plants is 20-25 cm, cover the soil after sowing, and the seed potatoes reach the ground 5-7 cm after the soil is covered; harvest the corn in early September, take the corn stalks out of the field, and cover the ridge with machinery for 6-8 cm. Cover the ridge surface with an 80 cm wide polyethylene ordinary mulch, lightly press the soil on both sides, and gently pull out the potato seedlin...

Abstract

The invention relates to a high-yield cultivation method for autumn potato by mulching, which includes: seeding an early-maturing variety of corn in mid-May in a wide-and-narrow-row manner, wherein the large row spacing is 80-100cm, and the small row spacing is 30-50cm; soaking potato seeds in 5ppm gibberellin solution for 10 minutes in late July, and stacking the potato seeds in a shade for sprouting; seeding autumn potatoes among wide rows of the corn in mid-August, digging positions 10-15cm away from each corn row to obtain seed furrows, setting potato plant spacing as 20-25cm, and covering with soil after seeding, wherein the potato seeds is 5-7cm high off the land after soil coverage; and harvesting the corn in early September, carrying corn straws out of a field, mechanically covering ridges with soil as high as 6-8cm, covering ridge faces with common polyethylene mulch, and slightly digging out potato seedlings after mulching. Late irrigation and disease control are the same as that of the conventional cultivation method. The high-yield cultivation method is simple in operation and easy in polarization.

Description

technical field [0001] The invention relates to an agricultural cultivation technique, in particular to a high-yield cultivation method for autumn potatoes covered with plastic film. Background technique [0002] When sowing autumn potatoes in the second-season cropping area, it is hot and rainy, and the potato seeds after sowing are severely rotten and the emergence rate is poor; if the sowing is delayed, the potato growth period is short and the yield is low; during the expansion period of the potato pieces, the ridge surface is dry and cracked, and the potato pieces often turn green. The content of solanine in the tuber is high, and the taste is tingling. In the past two years, the reflective film covering at the emergence stage and the delayed cultivation technology of autumn potatoes have been promoted, but the cost is high and the operation is complicated. Interplanting autumn potatoes between corn rows can provide shade in the early stage, lower the ground temperatur...
