Full-film double-ridge furrow sowing cultivation technique for potato, suitable for arid regions
The full-film double-ridge furrow sowing cultivation technique for potato is a drought-resistant planting technique suitable for the arid and semi-arid regions of northern China, achieved by forming large and small ridges according to belt width and implementing full-ground coverage, integrating moisture conservation, rainwater harvesting, warming and yield increase. Its main advantages are: (1) By fully covering the large and small ridges with plastic film, all rainfall during the potato growing period is fully collected; in particular, the tiny rainfall of about 5 mm in spring is gathered through the film surface into the rainwater harvesting furrows, effectively solving the problem of sowing being seriously affected by spring drought in dryland farming areas, thereby ensuring normal emergence of potatoes;

High-yield Cultivation Techniques for Soybean with Wide Ridge and Narrow Row Close Planting
Wide ridge and narrow row close planting of soybean can increase the canopy leaf area index, make full use of light energy, and achieve the goal of increasing yield. (1) Site selection and land preparation. The best preceding crops are wheat, corn or potato. Ridging is done as sowing proceeds. The ridge spacing is 130 cm, the ridge height is 25 cm, and the ridge top width is 3O cm. (2) Variety selection. For wide ridge and narrow row close planting of soybean, the varieties selected should generally be 168, ZOQI, 9409B, Fengshou 544, Mijiawang, Hefeng 25, Hebing 93-BS, etc. Seed selection should be carried out before sowing.

Detailed Explanation of Key Points of Potato Wide-Ridge Cultivation Technology
The potato wide-ridge cultivation technology uses 180 kg/hectare of virus-free seed potatoes, adopts 80-90 cm wide-ridge cultivation, 30 cm deep loosening, changes single-layer tuber formation to multi-layer dispersed tuber formation, mixed application of farmyard manure and chemical fertilizer, chemical control of pests and diseases, and a comprehensive cultivation method combining chemical weeding with manual weeding. 1. Seed treatment: select virus-free seed potatoes Kexin 13 or Kexin 18. 30-40 days before sowing, take the seed potatoes out of the cellar and store them in a place above 10°C to break dormancy and promote sprouting. At the same time, remove diseased and rotten potatoes. 5-7 days before sowing,

What are the technical advantages of dense planting cultivation of potatoes in wide ridges?
China has a history of more than 400 years of potato cultivation, but what continues to this day is still the 65cm narrow-ridge potato planting method, with an average yield of 26,000 kg/hm. This planting method results in shallow hilling, insufficient soil storage capacity, tubers that are easily exposed, and an increase in deformed tubers. At the same time, because the ridge spacing is small and the plants are large, the spaces between ridges become congested, which is unfavorable for ventilation, makes humidity too high, and forms a field microclimate, making it extremely easy for the devastating disease -- potato late blight -- to occur and spread, producing large numbers of diseased tubers and even causing total crop failure.

New Technique for Whole-Seed Potato Cultivation with Plastic Mulch and Double Rows on High Ridges
1. Reasonable crop rotation and stubble reversal To economically and effectively utilize soil fertility and prevent soil-borne diseases, pests, and weeds, avoid continuous potato cropping or planting potatoes on the stubble of other root and tuber crops. Also, do not rotate with other Solanaceous crops such as eggplant and tomato, otherwise yields will be reduced by 15%-20%. Potatoes can be rotated with cereal crops and legume crops for more than 3 years. 2. Land preparation and ridge formation Potatoes are suitable for planting in deep, loose soil, with deep plowing and fine land preparation. After harvesting the previous crop, promptly clear the stubble, plow deeply about 25 cm

Detailed Explanation of the Double-Ridge High-Mound High-Yield Cultivation Technique for Potatoes
Potatoes grown with the double-ridge high-mound cultivation method are deeply favored by the vast number of farmers because they are free of disease, show a large yield increase, have good tuber shape, and a high marketable rate. As a result, double-ridge high-mound cultivation has become a technical measure commonly adopted by farmers in Xuanwei. The characteristics of the "double-ridge high-mound" potato cultivation method are the optimized integration of good varieties, good methods, and a good growing environment; the goal is to increase potato yield and the marketable rate and raise farmers' incomes; the core of the technique is the "six changes," namely: first, change from using multiple, inferior, and mixed varieties to applying leading improved varieties; second, change from intercropping corn with potatoes to growing potatoes alone;

Detailed Explanation of the Two-Ridge-One-Furrow Soybean Cultivation Method
The two-ridge-one-furrow cultivation method is based on 70cm ridge planting, with an additional seedling row added in the furrow every other ridge, a large row spacing of 140cm and a small row spacing of 35cm, sparse inside and dense outside within the furrow and platform, and hole sowing cultivation. Reasons for increased yield: (1) Increased green area and improved canopy structure. (2) Improved ventilation and light penetration conditions. (3) Improved drought resistance. (4) Fully utilized heat resources and raised soil temperature. (5) Improved soil nutrient supply conditions. Technical key points: (1) Rotation

Detailed Explanation of Key Points for Soybean Narrow-Row Dense Planting Cultivation Techniques on Small Ridges
Key points for soybean narrow-row dense planting cultivation techniques on small ridges: 1. Crop rotation: rotate in a three-zone rotation with crops such as wheat and corn, or rotate every other year with crops such as wheat and corn, to avoid continuous cropping. 2. Soil tillage: first, flat plowing and ridging. Second, rotary tillage and ridging. Third, ridging while sowing. 3. Variety selection: choose semi-dwarf, semi-determinate type varieties with strong stems that do not lodge, are disease-resistant, high-yielding, and suitable for dense planting; the maturity period should be suitable or slightly earlier than local varieties. 4. Seed preparation: first, seed selection. Second, seed treatment. 5. Fertilization: first, increase application of

Key Techniques for Ridge Cultivation of Potatoes with Plastic Mulching
After the seed potatoes are planted, flatten the ridge surface with a flat shovel, which helps with weed control and film covering. For 667 sq m, use 80 ml of the herbicide Dual mixed with 40 kg of water and spray it on the ridge surface. The herbicide should not be sprayed all at once; leave a small portion and spray it in the furrows after the film is covered. To prevent weeds, 667 sq m requires 4 kg of 90 cm wide micro-film. When covering the film, be sure to seal the two sides and the ends of the ridge tightly with wet soil, and seal another horizontal line with wet soil on the ridge surface every 6-7 m to prevent strong winds from lifting the plastic film and affecting the heat preservation effect. After the seed potatoes emerge

Detailed Explanation of the Double-Ridge, High-Moisture, High-Yield Cultivation Technique for Potatoes
The main feature of the double-ridge, high-moisture potato cultivation method is the optimized integration of good seed, good methods and a good growing environment. Its core technique is the "six changes": first, changing from the use of multiple, inferior and mixed varieties to the use of leading improved varieties; second, changing from intercropping corn with potatoes to growing potatoes alone; third, changing from the "starry sky" planting method to double-ridge, high-moisture cultivation; fourth, changing from one intertillage and ridging to two or three intertillages and hillings; fifth, changing from one-sided application of nitrogen fertilizer to balanced fertilization based on soil testing and formula (mainly phosphorus and potassium fertilizers); sixth, changing from rough field management to fine management (with the focus on timely irrigation
