Greenhouse potato organic cultivation

1. Variety selection: Choose healthy potato chips with no pests and diseases, good potato shape, soft and smooth potato peels, moderate size, relatively tight potato and obvious variety characteristics, and select the new series, Kenon series, and Dongnong 303. Other varieties, including Kexin No. 4 with smooth appearance and yellow skin and white meat, yielded about 2,500 kilograms per mu.

2. Pregermination: The germination period should be determined according to the cultivation time. The cultivation of greenhouses with small sheds is usually planted in mid-February and the priming of the mid-January will begin. Germination method: The buds have a large and prosperous cut. The buds are not very prosperous and can be cut in two or three pieces. The weight of the pieces is not less than 25 grams. After the potatoes are chopped, they should be mixed with plant ash or tanned in the sun until the wounds are healed. Conditioned alcohol-soaking cutters can be used after 8-10 minutes for cutting and then germination. In January, germination measures should be taken to preserve the buds. Generally, small arch sheds are placed in large arch sheds, and grass drapes are placed on small arch sheds at night. The shed chooses to dig the irrigating pool with a depth of about 15 centimeters from the location of the leeward sun. The size should be determined according to the amount of potatoes used. Usually, the potato variety per acre needs about 40 square meters of priming pond. After the pond is dug, a layer of fine tidal sand with a thickness of about 2 cm (not too wet) shall be laid in the pool and then a layer of potato pieces shall be placed on the pool so that three layers of potato chips can be placed. Cover it with sand. Take a small shed above it and cover it with straw at night. 10 days before transplanting, when the shoots are 1-2 cm long, all the potato seeds must be picked up and sun cured in the sun to make the shoots robust and then planted in the field.

Second, cultivation and management

1. Cultivation: The cultivation of greenhouses is generally in early February. 7-10 days ahead of time, the greenhouses are built well, and the land is well-turned and well-grounded. Each mu is roasted with 6,000 kg of farmyard fertilizer and 80-100 kg of organic vegetable fertilizer. After deep-turning, it is then turned into a high ridge with a width of 90 cm and a height of 20 cm. Plant 2 lines per ridge, spacing 50 cm, plant spacing 20 cm, and open 6-8 cm deep shallow ditch, place a potato seed every 20 cm in the ditch, cover with water after watering, and finally catch a small shed.

2. Field management: Watering in time according to flooding after emergence, in principle, keep the soil dry and wet during the whole growth period of the potato. The water requirement from emergence to budding is less, and budding to anthesis is the period of maximum water requirement in a potato's life, and sufficient moisture should be maintained. That is to say, it must be poured once per year during the expansion of tubers. The top dressing is applied when the potato is freshly knotted, and 50 kg of organic fertilizer is applied per mu. Potatoes are easy to grow outside the soil surface when they are inflated. To increase production and improve commodity quality, the soil must be cultivated. The soil can be divided into two stages. The first time the seedlings are ridged, the second time when the potato begins to expand.

Third, pest and disease control

Potato sheds are less and lighter, pests are mainly locusts, and can be sprayed 1-2 times with imidacloprid or fipronil when found; the disease is mainly an epidemic disease, and is sprayed with phytotoxin or Rhizoctonia 2-3 times during the onset.
