potato

Variety selection uses Kexin No.1, early Dabai and other varieties with good yield and disease resistance.

Grab early sowing rate of 2000 kg per hectare of organic fertilizer, 30 kg of compound fertilizer. After fertilization, plough the soil to make hoe. The rake is 1.2 meters wide, and the groove width and groove depth are both 20 cm. Dig a hole in late January sowing, seed sowing 1 piece of seed potato per hole, potato shoots upward, 3 lines each sowing, hole distance 25 centimeters, hole depth 8 to 10 centimeters, sowing 5500 holes per acre, seed amount of 150 kilograms per acre . Seed drying before sowing 3 to 5 days, piled up to cover the film heat preservation germination, seed potato grow short strong buds when cutting, each weighing not less than 30 grams. Use fresh grass ash to dry the slurry to prevent it from rot. After sowing, cover with high-quality ash fertilizer. Apply 50% acetochlor EC 80 ml plus 25 kg water spray to the soil and close the membrane.

The field management promptly broke the seedlings after emergence and cultivated the soil 2 or 3 times to create a loose soil environment for root and tuber growth. The potato planting stage applies 20 kg of urea per acre, and can be lightly watered with 1 to 2 times of water in the drought-tolerant period of the potato, and 30 kg of compound fertilizer is applied per acre.

green beans

Soil preparation Fertilization Potatoes should be cultivated in time after harvesting, 2000 kg of organic fertilizer per hectare of roots, 30 kg of superphosphate, and less available nitrogen fertilizer.

Suitable for early sowing, selection of varieties such as Mingluo, Maoluo, and Zhongluo 2 with moderate plant height, strong resistance, moderate growth period, wide adaptability, and large potential for yield increase. Early sowing can win more accumulated temperature and light and increase production. Sowing in late May, 2 kg per acre. The rows are planted in large and small rows with 60 cm spacing, 40 cm spacing, 20 to 25 cm spacing, 2 seedlings per hole, and 12,000 seedlings per mu.

Field management in time of cultivating and weeding, as soon as possible under the appropriate application of available nitrogen fertilizer, and spraying potassium dihydrogen phosphate. Mungbeans are prone to diseases such as viral diseases, anthrax, aphids, and soybean meal during the growing season, and they must be controlled. Harvesting ended at the end of September.

spinach

Land preparation before planting sow deep-turning land, per acre Jishi decomposed organic fertilizer 3,000 kg, 30 kg of NPK fertilizer, urea 15 kg. Site preparation is done, the width is 1.2 meters, the width is 20 centimeters, and the depth is 15 centimeters. Japanese all-powerful spinach, Dutch green beauty and other cold-resistant, high-yield disease-resistant varieties. Seed sowing in the middle and early October, the amount of 2 kg per acre, mixed with fine soil spread. After sowing, cover 1 cm thick fine soil, irrigating the water, and promote a complete seedling.

Field management vegetable seedlings have 2 to 3 true leaf time seedlings, Dingmiao seedlings, seedling distance 3 to 5 cm. Rational watering according to the public opinion, combined with 15 kg of water per acre of urea, with water, fertilizer, promote spinach growth. The diseases of spinach are mainly downy mildew and anthracnose, and the pests are mainly aphids. The market was harvested in December and finished in mid-January of the following year.
