Embodiment 1

[0021] The planting area is the area above 800 meters above sea level in Nanjiang County, and the germination of potatoes begins in early February.

[0022] Including the following steps:

[0023] (1) Cut into pieces to accelerate germination: 15 days before sowing, cut the potato seeds into pieces to ensure that each piece has at least one bud eye. After cutting, dry mix with plant ash or carbendazim powder and dilute 180 times with water, then soak and sterilize the seeds. After drying, start the germination of the seedbed. The method of germination is: use straw to germinate in the corner of the room above 18°C, one layer of straw and one layer of seed block; sprinkle water once during the germination period. start planting;

[0024] (2) Site preparation and ditching: When ditching, use a large row of 120 cm, a row spacing of 35 cm, and a nest spacing of 20 cm. When planting, the buds of the seed blocks face down, and then fertilize. 2000 kg of farmyard manure per mu is m...

Embodiment 2

[0027] The planting area is northeastern Sichuan at an altitude of more than 800 meters, and the germination of potatoes began in early February.

[0028] Including the following steps:

[0029] (1) Cutting into pieces to accelerate germination: 12 days before sowing, cut the potato seeds into pieces to ensure that each piece has at least one bud eye. After cutting, dry mix with plant ash or carbendazim powder and dilute 180 times with water, then soak and sterilize the seeds. After drying, start germination in the seedbed. The method of germination is: germination with plastic film in the east-west direction in an outdoor ventilated and sunny place, one layer of plastic film and one layer of seed blocks, stacked three layers, then covered with arch shed film, and covered with straw curtains at night to keep warm; Sprinkle water twice during the germination period, and start sowing when the buds grow to 0.3-0.5 cm long;

[0030] (2) Site preparation and ditching: When ditchin...

Abstract

The invention discloses a method for planting potatoes in early spring in areas above 800 meters above sea level in Nanjiang County. Plant with a nest distance of 20 cm. When planting, the buds of the seed block face down, and then fertilize. When fertilizing, use the method of spreading evenly; (3) Release the seedlings and manage the seedlings: it is not suitable to water in the early stage of potato growth, and wait until after flowering Water again, if there is a drought and no rain, water once every 20 days to prevent insect damage at the seedling stage. In the present invention, the germination rate of potatoes is high by adopting a special method for accelerating germination by cutting into pieces. Not afraid of natural disasters such as frost. The potato sprouts are long and strong, the potatoes absorb nutrients evenly, the potatoes are large, the yield per mu is high, and the management is simple.

Description

technical field [0001] The invention belongs to the field of potato planting, and in particular relates to a method for planting potatoes in early spring in areas above 800 meters above sea level in Nanjiang County. Background technique [0002] Nanjiang County is located at the southern foot of Micang Mountain on the northern edge of Sichuan, adjacent to Tongjiang River in the east, Bazhou, Enyang in the south, Wangcang in the west, and Nanzheng County in Shaanxi Province in the north. The terrain in the territory is high in the north and low in the south, the lowest altitude is 370 meters, the highest altitude is 2507 meters, and the average altitude is 1100 meters. It is 84.3 kilometers long from north to south and 31 kilometers wide from east to west. The terrain in the territory is complex, with vertical and horizontal streams and ditches, and mountains and rivers are interdependent, so it is known as "eight mountains, one water and one field". [0003] In Nanjiang Co...
