Potato, cabbage, eggplant three-dimensional planting mode

In the potato (potato) secondary cropping area, the use of the characteristics of dwarf, early maturity, and sweetness of potato trees was used to interplant between potato and other vegetable crops. This model generally produces 1,000-1,500 kilograms of potatoes, 1,500-2,000 kilograms of cabbage, and 3,000 kilograms of eggplant. First, planting specifications of the bandwidth of 80 cm, ridge type planting, ridge height of 15 - 18 cm, ridge back width of 20 cm, furrow width of 60 cm. One row of potatoes was planted on a ridge with a plant spacing of 20 cm and 4000 plants per acre. Two rows of spring cabbage were planted in a row of furrows with a row spacing of 40 cm, a plant spacing of 40 cm and 4000 plants per acre. After the cabbage is harvested, one line of summer eggplant is planted with a plant spacing of 40 cm and about 2000 plants per acre. Second, the cultivation techniques points (a) to apply base fertilizer potatoes, eggplant, etc. need a larger amount of fertilizer, particularly like phosphorus, potash fertilizer. Therefore, combined with deep plowing before winter, 3000-4000 kg of high-quality circumfertile fertilizer per acre, 40 kg of superphosphate; when ridged in early spring, basal fertilization is applied again, 2000 kg of Mushi circle fertilizer, 100 kg of plant ash or 20 kg of potassium sulfate, over Calcium phosphate 20 kg, during plant growth, timely fertilizer according to need. (2) The optimum nighttime temperature for timely potato tuber expansion in potato is 12°C-17°C, and the optimum soil temperature is 16°C. The arrangement of the cultivation season should arrange the potato period at the soil temperature of 12°C-20°C. The suitable sowing date for spring sowing is in the middle and middle of March. 15-20 days before sowing, the seed potatoes will be warmed and germinated under the condition of about 20°C. Seed the top buds of potatoes, or use a sprayer spray seed potatoes. The management of potatoes after sowing is mainly cultivating, watering and fertilizing. (3) Brassica oleracea and eggplant and early growing seedlings were planted in the middle and mid-December of December. Early-maturing varieties were selected and transplanted with Yangshuo, transplanted in mid-March, and harvested in mid-May and mid-May. Eggplant is sown from late February to early March and transplanted in mid-May. Cabbage and eggplants are managed in the same way as they are grown.
