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 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;

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

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.

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,

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.

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;

Key Points of High-Ridge Double-Row Potato Cultivation Technology
High-ridge double-row potato cultivation refers to a planting method using wide and narrow rows, where soil from the wide rows is hilled onto the narrow rows, forming raised beds that stand more than 25cm above the ground. Trials have confirmed that potatoes grown on ridges and beds have the advantages of earlier emergence, a higher proportion of large and medium tubers, and higher yields; ridge-bed cultivation increases yield by 19.1% compared with flat-bed cultivation. The specific cultivation techniques are as follows: 1. Fine seedbed preparation. Potato is a shallow-rooted crop. After the tubers are planted and before emergence, the better the root system develops in the soil, the stronger the plant growth after the seedlings emerge.

What are the main advantages of the three-ridge soybean cultivation technique?
Main advantages of the "three-ridge" soybean cultivation technique: First, deep soil loosening breaks through the plow pan, deepens the tillage layer, and improves soil structure, which benefits soybean root development and nodule formation; deep loosening creates a soil structure with both loose and firm zones, improving soil permeability. Second, layered fertilization within the ridge body improves fertilizer use efficiency and delays the fertilizer supply period, preventing nutrient deficiency late in the growing season. The small precision seeders currently used in production can all achieve deep placement of chemical fertilizer; they can also apply seed fertilizer and base fertilizer at the same time. Third, double-row precision

Detailed Explanation of the Key Points of the Three-Ridge Soybean Cultivation Technique
In the early 1980s, Heilongjiang Bayi Agricultural University combined agricultural machinery with agronomy and gradually formed a complete, effective, comprehensive mechanized high-yield soybean cultivation technology system, called the "three-ridge" (or "three ridges") cultivation technique. The so-called "three-ridge" refers to the use of three mechanized operation techniques on the basis of ridge tillage: first, deep loosening of the ridge body and furrow in stages and at intervals; second, layered deep application of base fertilizer; third, precision double-row sowing on the ridge. The above three operations are completed by machinery in one pass. After this technique was promoted, various regions made some improvements according to
