Interplanting autumn soybeans in rice paddies yields good increases in both output and income
According to trials: after the mid-season rice harvest, by using the temperature and light conditions in the field, planting an additional season of autumn soybeans can increase soybean yield by 60-120 kg/mu, with economic income of 150-420 yuan/mu, giving a relatively good effect of increasing both output and income, and it is suitable for extension in ratoon rice areas below 400 m in altitude. The key technical points are as follows: 1. Suitable site and good varieties: fields below 400 m in altitude with no water for retaining ratoon rice, as well as all rice seed production fields, can be planted. After the rice grains have set, open ditches to drain water; after the rice harvest, promptly clear weeds and rice stubble, without plowing, and according to

How to grow spring-planted soybeans in Northeast China? A detailed explanation of the technical guidance
In the autumn and winter of last year, precipitation in Northeast China was lower than normal, soil moisture was insufficient, and drought was relatively severe. This spring there has been more rain and snow, temperatures began to rise rapidly in early April, and temperature and precipitation are close to normal. The Soybean Expert Steering Group of the Ministry of Agriculture, together with the National Agricultural Technology Extension Service Center, based on full investigation, proposed the following technical guidance for spring soybean planting: 1. Strictly select excellent varieties. Because of the dry climate last autumn, soybeans may not have matured normally physiologically at harvest, and mechanical threshing increased the possibility of damage to the seed embryo

Detailed Explanation of Mid-to-Late Stage Management Techniques for Soybeans in Northeast China
The main soybean-producing areas in Northeast China and Inner Mongolia have generally suffered from a disaster pattern of spring drought followed by spring waterlogging. Drought, low temperatures and insufficient sunlight have caused slow plant growth, and have also increased the occurrence of herbicide injury, weed infestation and diseases. At present, plants generally have 2-3 fewer compound leaves than in the same period of a normal year, and growth is uneven. Therefore, cultivating strong seedlings, building a reasonable population structure, promoting early maturity and preventing lodging are the key tasks in mid-to-late stage field management of soybeans, and at present special attention must be paid to draining waterlogged soybean fields and preventing waterlogging damage. Recently, the soybean expert guidance group of the Ministry of Agriculture and the National Agricultural Technology

Key Technical Points for Spring Soybean Sowing in a Year of Severe Drought in Northeast China
Current drought situation in Northeast China and technical guidance for spring soybean sowing: I. Precipitation and temperature conditions last winter and this spring. In the autumn and winter of last year, the drought in Northeast China was severe, precipitation was lower than normal, and soil moisture was insufficient. From January to October 2007, the average precipitation in Heilongjiang Province was 402 mm, 20% less than the same period in previous years. In addition, this year's widespread "dry sealing of the soil" at the onset of winter was not conducive to soil moisture conservation. Since the beginning of winter, precipitation in southern Qiqihar, most of Daqing, the Hegang area, and some counties and cities in Jiamusi has been more than 90% less than the same period in previous years; other areas have had 10% to 90% less. In January 2008, the average precipitation across Heilongjiang Province was only 0.1 mm, 97% less than the same period in previous years, with most of the Songnen Plain and the western Sanjiang Plain receiving no precipitation at all for the entire month. After entering February, precipitation in various places continued to remain low. Snow depth across Heilongjiang Province also dropped significantly. Compared with the same period in previous years, snow depth in most areas of the province was about 25 cm less. In 2008, the area of cultivated land affected by drought before sowing in Heilongjiang Province may reach 50 million mu. In addition, the continuous warm winter was extremely favorable for soybean pathogens and pest eggs to survive the winter safely, and soybean diseases and insect pests may occur more heavily this year. The spring drought situation in Inner Mongolia is similar to that in western Heilongjiang Province.

How to grow soybeans in Northeast China? Main recommended high-oil, high-yield varieties and techniques
The Northeast high-oil, high-yield soybean demonstration project implemented by the state, after two years of development, has introduced a group of excellent high-oil soybean varieties and advanced production techniques, which are gradually being widely applied in large-scale production. On this basis, the Northeast high-oil, high-yield soybean demonstration technical expert group offers the following recommendations for the seed and techniques used in high-oil soybean production in the region in 2004: In 2004, Heilongjiang Province and its reclamation areas can, according to the accumulated temperature and production conditions of different regions, continue to use the high-oil varieties that had already been successfully promoted in large-scale production in 2003,

Key Technical Points and Management Methods for Winter Soybean Cultivation
1. Sowing time. The sowing window for winter soybeans is quite flexible; yields do not differ noticeably when sowing from early April to early June. In practice, to ensure winter soybeans obtain a suitable stand of basic seedlings, in addition to correctly determining the number of hills per mu to provide the density basis, sowing should generally be done during the period before the corn canopy closes, so that the soybean seedlings have already formed the necessary vegetative mass before shading intensifies, which helps ensure the basic seedling stand. In strip-planting areas, it is best to sow together with corn or slightly later, that is, in mid-to-late April; in sole-cropping areas after the small spring crop, it is best to sow in early-to-mid May. 2. Planting method. Winter soybean planting method

Production Methods and Multifunctional Applications of Soybean Dietary Fiber
1. Physiological Functions of Multifunctional Soybean Dietary Fiber Soybean dietary fiber mainly refers to the general term for those macromolecular carbohydrates that cannot be digested by human digestive enzymes, mainly including cellulose, pectin, xylan and mannose, etc. Although dietary fiber cannot provide the human body with any nutrients, it has important physiological functions for the human body. Dietary fiber has significant effects in lowering blood pressure and plasma cholesterol, and regulating gastrointestinal function, blood sugar and insulin levels. Multifunctional Soybean Fiber (MSF) is mainly composed of dietary fiber and protein, with contents of 67.98% (dry basis) and 19.75% respectively, making it a good protein-fiber additive. Studies have shown that adding a small amount of MSF has a good strengthening effect on medium-gluten or low-gluten flour; within a certain addition range, it can not only increase the dietary fiber and protein content of products, but is also very beneficial for improving the quality of products such as bread, noodles and biscuits. MSF may be the best-functioning of all dietary fibers, far beyond what other synthetic fibers (such as litesse, polydextrose) can match. Multifunctional soybean dietary fiber is a high-quality dietary fiber obtained from fresh okara as raw material through special heat treatment, and it has good effects in regulating blood sugar, lowering blood lipids and promoting defecation.

How to prevent soybean flower and pod drop? Practical methods are here
1. Topdressing according to the field and the seedlings. For fields where the plants cannot close the rows in time during the flowering period due to lack of fertilizer, topdressing can be applied once more at the early flowering stage. Generally, applying 5 kg of urea or 10 kg of ammonium sulfate per mu can reduce flower and pod drop. 2. Foliar spraying of fertilizer. During the flowering and podding period, generally use 0.5 kg of urea, 1.5 kg of superphosphate, 0.25 kg of potassium sulfate, and 25 g of borax per mu, add 50 kg of water to extract the infusion, and spray it on the leaves. It is best to spray on cloudy days or after 4 p.m., which helps preserve flowers, increase pods and seeds
