A bonsai enthusiast's brief discussion of eight suggestions for narrowing the gap between Chinese and Japanese bonsai
Returning recently from the "China Zun" event in Yuyao, I have many reflections: admiration for the contributions made to China's bonsai cause by more industrialists like Principal Ma of Gaofeng Middle School, reflection on the exhibition halls full of imported Japanese bonsai, reflection on Kunio Kobayashi's bonsai skills

Cotton narrow row spacing should be widened: The second in a series of recommendations from rural advisory services in 2008
Before sowing, the author visited and investigated some cotton regions in Hebei, Shandong, Shanxi and Shaanxi. In most areas the cotton narrow row spacing is too narrow, seriously hindering the normal growth and development of cotton plants, and a planting reform of the population structure is essential. The pressing task is to widen the narrow row spacing. In order to carry out plastic film mulching of cotton, cotton farmers mostly adopt wide-and-narrow row sowing, sowing two rows at once. Most areas use 90 cm wide plastic film, with the narrow row spacing about 45 cm wide. This is not conducive to the normal extension of fruiting branches and flowering and boll setting, and also causes unbalanced growth on both sides of the cotton root system. Very

Key Technical Points for 45 cm Narrow-Row Dense Planting of Soybean
The 45 cm narrow-row dense planting cultivation technique for soybean is a new technique we selected in Dunhua City in 2004 on the basis of introducing the soybean narrow-row dense planting cultivation technique from Heilongjiang, adapted to the climate, soil and cultivation characteristics of our region, and it is a new breakthrough in the reform of the farming system in Dunhua City. In 2005, trials were conducted at the farms of Guandi, Heishi and Shaheyan; the average yield of soybean in the trial area was 202.9 kg per mu, 24.9% higher than the control. In 2006, 1500 mu were promoted citywide, with an average yield of 203.52 kg per mu and a maximum

Detailed Explanation of Key Technical Points for Narrow-Row Dense Planting Cultivation of Soybean
Reducing row spacing and increasing row number, that is, narrow-row dense planting, is one of the effective ways to increase soybean yield. This cultivation method is divided into three forms: first, wide-ridge narrow-row dense planting, which is a wide-bed narrow-row dense planting cultivation method that combines the original two ridges into one ridge or one and a half ridges into one ridge. The wide ridge width is 97.5-140 cm, 4-6 rows are sown on the ridge, and the seedling stand per hectare is 400,000-500,000 plants. At present, 70 cm ridge cultivation in production can generally increase yield by about 20%. This cultivation technique is suitable for use by farmers in townships in the central-southern and eastern low-lying, wet, and waterlogged areas with relatively high productivity levels.

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.

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.

What are the key technical points for flat-planting narrow-row dense planting of soybeans?
Key technical points for flat-planting narrow-row dense planting of soybeans: 1. Seed and treatment: For variety selection, choose suitable varieties according to the local ecological type and local conditions. 2. Seed quality: It must reach Grade II improved seed or above under the seed grading standard. 3. Seed treatment: Use seed coating agent for seed dressing, selected according to the types of pests and diseases and soil conditions. 4. Rotation and tillage land preparation: For crop rotation, use a rotation of more than 3 years, do not plant continuously or on adjacent stubble, and the previous crop should mainly be wheat-type crops. For tillage, adopt mainly deep loosening, combining loosening and harrowing, to facilitate drought resistance and moisture conservation. 5

Detailed Explanation of Key Points for Soybean Narrow-Row Dense Planting Cultivation Technology
Soybean narrow-row dense planting cultivation is currently an advanced cultivation technology with a relatively large application area and rapid development speed in international soybean cultivation. Heilongjiang Province began this practice in the early 1990s and designated it as a key research project of the Provincial Party Committee in 1995. 1. Select suitable varieties and carry out proper seed treatment. Narrow-row dense planting must select short-stalked or semi-short-stalked varieties with lodging resistance and high yield potential. Currently, the more suitable varieties applied in production include Hefeng 25, Hefeng 35, Suinong 14, Beifeng 14, Beifeng 1

Soybean Narrow-Row Dense Planting Cultivation Methods and Technical Key Points
Soybean narrow-row dense planting cultivation is currently an advanced cultivation technique with a relatively large application area and rapid development rate in soybean cultivation internationally. Since the early 1990s, our province, on the basis of absorbing and digesting foreign techniques and in combination with the province's natural characteristics and production conditions, has explored a soybean narrow-row dense planting cultivation technique suitable for the province's production conditions. Soybean narrow-row dense planting is divided into two modes: flat-planting narrow-row dense planting and ridge-planting narrow-row dense planting. The former high-yield cultivation technique is flat sowing, flat management, a narrow-row dense planting cultivation that stays flat throughout, and the latter refers to narrow-row dense planting cultivation based on ridge planting

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
