Embodiment 1

[0019] Penny Town, Jintang County, with an area of ​​10 mu, was sown on January 20, 2014 and harvested on May 31, using the first purple potato variety approved by Sichuan Province: Rong Ziyu No. 5. Strictly select seed potatoes, and use virus-free whole small potatoes for sowing. It is suitable for areas with high humidity and rain. For ungerminated seed potatoes, germination treatment is carried out. Do not pile up too thick to prevent rotten seeds.

[0020] Purple Potato Planting:

[0021] (1) Soil preparation and furrowing: Plow tillage after the harvest of the previous crop, with a plowing depth of 20 to 30 cm, and then furrow 80 cm from the center of the furrow, with a depth of 25 cm.

[0022] (2) Base fertilizer: base compound fertilizer (N:P 2 o 5 :K 2 O=15:15:15)1500kg / hm 2 .

[0023] (3) Sowing: Seed potatoes were sown in early January. Sowing in double rows and staggered nests in high compartment ridges, planting two rows in staggered nests, row spacing 20c...

Embodiment 2

[0030] Penny Town, Jintang County, with an area of ​​3 mu, was sown on January 21, 2014 and harvested on May 28, using a purple potato variety imported from Gansu: Black Beauty. Strictly select seed potatoes and use virus-free seed potatoes.

[0031] Seed potatoes are cut into large pieces. It is suitable for areas with less humidity and less rain when sowing. When cutting into pieces, cut them longitudinally from the top of the potato to the navel, so that each piece has bud eyes on the upper part of the tuber; each potato cube weighs 30g to 40g and has 2 to 3 bud eyes. After every 10 minutes of use of the cutter or when cutting diseased or rotten potatoes, soak in 75% alcohol for 1-2 minutes or scrub and disinfect. It is recommended to use two cutters alternately. After cutting into pieces, mix the seeds with plant ash. Seed potatoes are soaked in 1mg / kg potassium permanganate solution for 10-15min.

Abstract

The invention discloses a southwest hilly area dry land purple potato cultivation method, and relates to the technical field of crop cultivation. The southwest hilly area dry land purple potato cultivation method specially includes: deeply plowing land before sowing, and applying compound fertilizer on a base of the land; sowing purple potato seeds with bud eyes after disinfecting the purple potato seeds with the bud eyes; laying a drip irrigation belt among rows of a ridge side, covering the drip irrigation belt with a black mulching film, and confirming irrigation frequency according to conditions of a water source; under the condition of needing irrigation once, irrigating the land in a squaring period; under the condition of needing the irrigation twice, respectively irrigating the land in a seedling emergence period and the squaring period; under the condition of needing the irrigation thrice, respectively irrigating the land in the seedling emergence period, the squaring period and a blooming period; under the condition of needing the irrigation for four times, respectively irrigating the land in the seedling emergence period, the squaring period, the blooming period and a mature period; keeping the irrigation amount once within a range from 15 cubic meters to 20 cubic meters, and keeping drop irrigation time once within a range from 6h to 8h; spraying 0.3% monopotassium phosphate on leaf surfaces of the purple potatoes in a tuber expansion period of the purple potatoes. The southwest hilly area dry land purple potato cultivation method adapts to ecological conditions and an existing planting technology of the Sichuan hilly area dry land, and observably improves a yield, quantity and income of the purple potatoes in the Sichuan hilly area dry land.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a method for cultivating purple potatoes in dry land in the southwestern hilly area. Background technique [0002] Purple potatoes are a sunrise industry that has emerged in recent years. Because purple potatoes are rich in selenium and anthocyanins, and anthocyanins have many health functions for humans, such as scavenging free radicals, anti-tumor, preventing diabetes, protecting eyesight, etc., purple crops are regarded as important physiological health food. Purple potato tubers are rich in anthocyanins. As a dominant crop in the adjustment of agricultural industrial structure, it is gradually transforming into a beneficial crop, and its role in increasing farmers' production and income, healthy food sources and the development of characteristic industries is becoming increasingly apparent. [0003] Sichuan Province is the largest potato producing provin...
