Key Techniques for High-Yield Cultivation of Potatoes with Rice Straw Core Padding
1. Variety selection: For fresh potato vegetable varieties, choose Zihua 851, Zhongshu No. 3, Favorita, and other varieties. 2. Land preparation and bed making. Soil selection: Potatoes have a wide range of soil adaptability, and can be cultivated in both sandy soil and muddy land. However, choose loose-textured, well-drained, slightly acidic sandy soil with a pH of 5.5-6.5. Potatoes belong to the Solanaceae family and should not be continuously cropped with other Solanaceae crops or intensively mixed-cropped with them. Small high-ridge land preparation: After the previous crop is harvested, use a rotary tiller to plow and break up the soil, then use a bed-making machine according to the bed width including furrow of 110-

Key Points of High-Yield Winter Cultivation Techniques for Potatoes
1. Site selection and land preparation. For winter-planted potatoes, choose sandy loam soil with convenient transportation, deep topsoil, good drainage and aeration, rich organic matter, sufficient water sources, convenient irrigation and drainage, slightly acidic, and with rice as the previous crop. Land preparation should involve deep plowing and fine harrowing, ensuring the loose soil layer reaches more than 8 cun; form ridges and beds, with double-row planting ridge surface width of 2.5-2.8 chi, furrow width of 7-8 cun, requiring fine and crumbly soil clods, with ridge surfaces and furrow bottoms level and straight. 2. Seed potato treatment and cutting. After purchasing seed potatoes, remove diseased, rotten, and mixed potatoes, spread out the good seed potatoes and spray with 200-fold formalin or 600-fold Daconil

Rice Research Institute of Jilin Academy of Agricultural Sciences selects high-quality rice varieties
At the recently concluded evaluation of high-quality rice varieties (lines) in Jilin Province, "Jigeng 81" and "Jigeng 83", bred by the Rice Research Institute of the Jilin Academy of Agricultural Sciences, were rated as "high-quality rice varieties", and another 6 lines were rated as "high-quality rice lines". It is reported that this high-quality rice variety (line) evaluation was the third such event held after 1995 and 1998. The 10 high-quality rice varieties selected in the previous two events have already been promoted and applied on a large scale in production thanks to their good quality and high yield

Hanyou No. 3 rice saves water and resists drought, high-yielding and easy to grow
Rice is high-yielding, but afraid of thirst; upland rice is drought-tolerant, but its yield is slightly inferior. Shanghai rice experts ingeniously merged the advantages of the high yield of rice and the drought tolerance of upland rice into a single grain of rice seed, breeding the world's first water-saving and drought-resistant hybrid rice, "Hanyou No. 3". The author recently saw the mature "Hanyou No. 3" bent over from "exhaustion": each panicle bears 110 grains, and the yield per mu is better than that of conventional rice, while the rice field saves more than 50% of water. The new rice can go on the market in Shanghai at the end of the month. According to testing by a professional department, the grain quality of "Hanyou No. 3" reaches the Ministry of Agriculture's second-grade high-quality rice standard, and

Key Techniques for Mechanized High-Yield Cultivation of Densely Planted Soybean
The integrated mechanized high-yield cultivation technique for densely planted soybean is based on the three-ridge soybean cultivation technique, while continuing to maintain deep loosening, layered deep fertilization, and precision sowing. It draws on foreign experience in narrow-row dense planting and semi-dwarf varieties for increasing yields, and combines these with matching machinery to form an integrated mechanized high-yield cultivation technique, including flat-planting dense planting technology and small-ridge dense planting technology. I. Technical advantages 1. Reasonable dense planting increases yield. The technical feature is reasonable dense planting, uniform crop distribution, and increased crop photosynthesis. Select lodging-resistant semi-dwarf varieties, increase

Key Cultivation Techniques for Soybean Deep Loosening, Narrow-Row, Flat Sowing and High-Density Planting
Soybean deep loosening, narrow-row, flat sowing and high-density planting is another "new high-yield cultivation model" following "ridge three" and "large ridge density." It integrates advanced techniques such as deep loosening and rotary tillage for seedbed preparation, uses fertilizer to support density and density to increase yield, increases the canopy leaf area index, and improves light interception rate, achieving cost savings and efficiency gains in soybean production. Over two years, Luobei County promoted and planted 16000 mu in Tuanjie, Fengxiang, Zhaoxing and Taipinggou, with an average yield of 206 kg per mu, a 43% increase over the control.

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 Uniform Planting High-Yield Cultivation Techniques for Soybean
1. Determine planting density, row spacing and plant spacing according to the plant-type traits, branching and other characteristics of the variety. ① For dwarf, early-maturing, main-stem-type varieties that resist [unclear] branching: row spacing 30-40 cm, plant spacing 8-10 cm, seedling retention density 18,000-25,000 plants. 2. Determine planting density based on soil fertility level and management level. After determining the planting row spacing according to the variety, density should also be adjusted according to soil fertility conditions and water and fertilizer management level. 3. Sow early with sufficient soil moisture. Early sowing can significantly increase yield and increase fat content, generally sowing on June 10-20.

For high soybean yields, keep these four taboos in mind when planting
First, avoid continuous cropping and alternating cropping. Continuous cropping can reduce yields by 15%-20%, and alternating cropping can reduce yields by 20%-25%. Second, avoid sowing untreated seed. Sowing untreated seed can cause disease, insect pests and rodent damage, affecting emergence rate and yield. Third, avoid planting across regions. Adjust measures to local conditions and meet the requirements of the accumulated temperature technical indicators needed by the variety; otherwise, it will affect maturity and cause yield reduction. Fourth, avoid applying fertilizer at the roots. The rhizobia at the soybean roots have a nitrogen-fixing effect. Applying nitrogen fertilizer at the roots not only causes unnecessary waste, but also damages the fibrous roots and causes yield reduction. Only in this way can high soybean yields be achieved with confidence.

Ten key steps for high-yield soybean cultivation
First, the good-seed step. According to local factors such as climate, soil fertility, soil properties, growth period, rainfall, effective accumulated temperature, production level, and cultivation mode, choose high-oil and high-protein improved varieties with strong stress resistance and good yield performance. Second, the land-preparation step. In soil tillage, adhere to a soil tillage system combining subsoiling, plowing, harrowing, and rotary tillage, with subsoiling as the main practice; vigorously promote the subsoiling method, with a subsoiling depth of 40-50 cm. For spring land preparation on corn stubble, ridge up along the thawed soil and press in time to improve land-preparation quality, achieving clean ground with no stubble,
