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.

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

Detailed Explanation of Soybean Cultivation Technology with Film Mulching Between Rows on Wide Ridges
Heilongjiang Province is China's main soybean production area, with its planting area accounting for 7% of the national total and its current total output accounting for 11% of the national total. In the course of soybean production development, the Heilongjiang Reclamation Area has vigorously promoted scientific and technological innovation, resulting in a relatively large increase in soybean yield per unit area and total output. From 2001 to 2005, the average yield per hectare reached 2531.7 kg; in 2005, the average soybean yield per mu reached 178 kg, reaching or approaching the soybean yields of advanced countries worldwide.

Occurrence and Damage Characteristics of the Bridgeworm Pest on Lingzhi
The bridgeworm (Noctuidea) belongs to the family Geometridae. The lingzhi bridgeworm of this family (name to be determined) is an important pest damaging lingzhi. 1. Morphology and habits: The adult is 12 mm long with a wingspan of 25-28 mm, a small grayish-black moth. The antennae are filiform; the forewings are triangular with 8 black spots along the outer margin and one larger black spot in the middle of the costal margin; the hindwings are grayish-white. The egg is flat and round, 0.6-0.7 mm long and 0.4-0.5 mm wide, milky white initially and grayish-green before hatching. The mature larva is 22-25 mm long,
