High-yielding planting techniques of "four changes and one increase" soybean
The traditional sowing method of soybeans is narrow and too dense, coupled with many other reasons, the yield has always hovered in the 100~150kg. After years of experimental research. We have explored a new way to increase soybean production by more than 40%, that is, the technology of "four changes and one increase". In order to increase soybean yield, we should not only select new varieties with high quality and high yield, but also pay attention to crop rotation. According to the experiment, after continuous cropping for many years, soybean showed slow growth, short plant, yellow lower leaves, early defoliation, few pods and small seeds. Test

Great progress has been made in the project of "controlling soybean continuous cropping and reducing yield".
The reporter learned from the relevant departments that the project "Research and demonstration of key Technologies for controlling Soybean continuous cropping and yield reduction" invited by the Municipal Science and Technology Bureau has made significant progress after two years of scientific research. The project was carried out in Yilan and Bayan counties with the largest soybean area in Harbin. Through the study of key technologies, soybean varieties resistant to continuous cropping, such as Kenfeng 16, Heinong 48, Kangxian 4 and Hefeng 47, were selected. It was proposed that 45 kg of nitrogen, 60-67.5 kg of phosphorus, 67.5-75 kg of potassium per hectare were applied.

"Jinyi 30" soybean was selected as the leading variety promoted by the Ministry of Agriculture in 2008.
The new soybean variety "Jinyi 30" cultivated by researchers of crop Genetics Research Institute of Shanxi Academy of Agricultural Sciences was recently selected as the leading variety promoted by the Ministry of Agriculture in 2008, and it is also the only variety selected in our province. In order to comprehensively promote the project of entering households with science and technology, and guide the broad masses of farmers to select excellent varieties and apply advanced applicable technologies, the Ministry of Agriculture has introduced a total of 80 leading agricultural varieties to be popularized throughout the country this year. "Jinyi 30" is a large-grain variety. The rhizome of the plant is stout, the root system is developed, and the root system is well developed.

Control methods of soybean yellow-bellied lamp moth
The larva of yellow-bellied lamp moth is called caterpillar and leaf caterpillar, which is one of the main seedling pests of soybean. At the same time, this pest can also harm corn, millet, sunflowers, vegetables, weeds and fruit trees. 1. Morphological characteristics: the adults of Spodoptera litura are white, and there are many black spots on the forewings. The abdomen and back are yellow, with a black spot in the center of each segment, two black spots on each side, black stripes on the feet and yellow on the femoral nodes. The egg is hemispherical, the first birth is milky white, and then becomes grayish yellow; the back and ventral surface of the larvae are yellowish yellow.

Soybean chemical control technology
Using chemical technology to control cultivation is a new technology in agricultural production. The chemical control cultivation of soybean can regulate the growth and development of the plant, increase the flower, protect the pod and increase the yield. The application of rare earth elements, also known as rare earth micro-fertilizer or rare earth nitrate, is a new type of rare earth element fertilizer pioneered and popularized in China. In the seedling stage and the first flowering stage of soybean, spraying the rare earth solution with a concentration of 0.03%, 0.04% and 0.08%, respectively, can increase the grain protein content by 5.

Causes of flower and pod shedding in soybean
1. Poor ventilation and light transmittance sunlight is not only the main energy for the production and accumulation of organic nutrition, but also the main factor for promoting plant rapid development and inhibiting overgrowth. Soybean has good ventilation and light transmission, which can make the climate between plants consistent with that of the upper part of plants, reduce the humidity between plants, increase light and temperature, accelerate leaf area transpiration and accelerate the speed of nutrient transport. 2. The loss of flowers and pods in barren soil is more than that in fertile soil. The soybean with shaded branches and leaves grows more normally than the plant, and the flowers and pods of the ventilated and transparent soybean fall off.

Management measures for flowering and pod stage of soybean
The main results are as follows: 1. The practice of topdressing flower and pod fertilizer shows that topdressing at flowering and pod setting stage has obvious effect on increasing flower and protecting pod, reducing shedding and increasing yield. Fertilization method: in the early flowering stage of soybean (early growth, delayed growth), 5-10 kg urea per mu. If the soil has strong fertility and the plant grows healthily, it should be applied less or not, so as not to cause the plant to grow madly, cause lodging or increase the shedding of flowers and pods. Combined with topdressing nitrogen fertilizer at flowering stage, foliar spraying phosphorus, potassium fertilizer, boron, molybdenum and other micro-fertilizer, it has a better effect of increasing yield. 2. Drought resistance

Management of soybean flower pod stage
Bean flower pod stage requires strong stems, thick green leaves, no spots. Field management is mainly to prevent premature aging, control excessive growth, protect flowers and increase pods, prevent shedding. 1. The flowering and pod setting period of soybean is the period when soybean absorbs most fertilizer. The yield of soybean can be increased by more than 15% by applying flower fertilizer skillfully. Soybean initial flowering stage generally every 667 square meters of urea 5-10 kg, poor growth should be more, strong growth luxuriant, should be less or not chase. Nitrogen fertilizer is applied in coordination with flowering stage, phosphorus, potassium fertilizer, boron, molybdenum and other trace fertilizers are sprayed on leaves. Generally spray twice, each time

Reasons for more flowers and less pods in soybean
At present, when many farmers are planting soybeans, they find that some plots of soybeans blossom more than pods, and the reasons are "five checks". First, check the soil structure, analyze whether the soil pH value exceeds the standard and continue the crop; second, check the fertilization content, analyze whether the proportion of nitrogen, phosphorus and potassium applied is reasonable; third, check the planting structure and analyze whether the planting density is reasonable; fourth, check the root of the plant; analyze whether there are diseases and insect pests in the root of the plant; fifth, check the soil moisture, analyze the size of the content, excessive drought and waterlogging will affect the pod setting rate. Only seriously.

Occurrence characteristics and control techniques of soybean red spider
The soybean red spider is a cinnabar spider mite, which belongs to the family Tetranychidae. Affected by high temperature and drought in 2007, soybean red spider occurred in an area of 120 million mu in Heilongjiang Province, resulting in a serious reduction in soybean production. According to the survey, in recent years, the damage of soybean red spiders has become the main position, generally reducing soybean production by 20-30% and serious plots by 70-90%. First, morphological characteristics. The adult is 0.3-0.5 mm long, reddish brown and has 4 pairs of feet. The female mite is 0.5 mm long and has eggs.
