Plastic film potato and carrot intercropping pattern

Film potato transplanted with large buds per mu 3,000 kg, per mu production value of 1630 yuan. Carrot ridiculing planting 4500 kg per mu, the output value of 1400 yuan per mu. The total output value of the two crops is 3030 yuan. The cultivation points are as follows: I. Cultivation Techniques of Plastic Film Potatoes (I) Variety Selection and Seed Potato Processing: 1. Variety Selection: Select "Kaixin No. 1" for Disease Resistance and Storage The fertility period is about 115 days. 2. Seed Potato Processing: In mid-January, the qualified seed potatoes will begin to be “warm seeds” and maintain 15-20°C. After 30 days, the seed potatoes grow buds, and the “warm seeds” can be cut at the end. 3. Graded germination: The cuts are classified according to the size of the buds, and they are respectively cultivated in Yangshuo. The width of Yangshuo is 1.7 meters, the length is 10 meters, the depth is 60-80 cm, the humidity is 65-70%, and the temperature is maintained at 20-25°C. After 20-25 days, when the buds grow 3-6 cm long, they can be sowed. (b) Land preparation and transplanting: Combine 5000-6000 kg of organic manure, 25 kg of diammonium, 10 kg of urea, 10 kg of potash, and 1–2 kg of zinc sulfate. According to a 1 meter long ridge spacing, a high 15-20cm high ridge, 2 rows per ridge plant spacing, 20cm spacing. Sowing time in mid-March, 5700-6600 plants per acre, after the cover film. (III) Post-planting management: Potatoes should be planted in time after emergence, and buds should be removed in time for budding so that the nutrients can concentrate on tubers and tubers. This measure can increase production by 5-10%. Second, the cultivation of carrot technology (a) species selection: the use of purified and rejuvenated local varieties of "candle Taiwan" and Japan's "Kuroda five inch ginseng" varieties. (2) Timely sowing: After the potatoes are harvested in early July, timely fertilization and sowing of soil will be carried out. The sowing method was changed to sowing and drilling. The specific method is after the soil is deep-leveled, and the ridge length is 50 centimeters, the ridge height is 10 centimeters, and the ridge width is 25 centimeters for ridges. Each ridge type is double row, the small row spacing is 15 centimeters, the ditch is sown, and the ditch is 2 centimeters deep. 1.5 centimeters, planted under foot, once to save seedlings. (3) Field management: Summer sowing, serious grass shortage, 25% of mu turfgrass net 100 kg watered 40 kg, spraying before emergence. Timely seedlings and Dingmiao, three-leaf land seedlings, four leaf Dingmiao, spacing 12 cm, cultivating once, can be earth once. At the same time, drought and water, topdressing 20 kg of potassium per acre. China Agricultural Network Editor
