What chemicals should be used to control soybean in cotyledon stage
It can be controlled with fomesafen (Huwei, Alternaria). Generally, when the soybean has 1 to 3 compound leaves, it is evenly sprayed with 25% fluorosulfonate water agent 68 ml per mu and 20 kg water per mu. Fomesafen is a selective contact herbicide, which is mainly absorbed by weeds, stems and leaves, and can also be absorbed by roots. It is suitable to be used in the field after self-growing rape is almost ready.

Soybean is not suitable for continuous cropping.
The control technology of continuous cropping of soybean can slow down the effect on yield. The effect on soybean yield. Different environments have different effects on soybean yield. ① heavy cropping and light continuous cropping; heavy ② in the west and southwest and light in the north and east; heavy thin land and light fertilised land in ③; heavy slope in ④, light in low wet area; heavy dry year and young rain in ⑤; heavy no or less fertilization in ⑥, light in more fertilizer; heavy sowing in ⑦ and light in ploughing and renovation; heavy underground diseases and insect pests in ⑧, light in underground diseases and insect pests; ⑨ mature land is heavy, newly reclaimed land is light; ⑩ drought is heavy, irrigation is light.

Non-continuous cropping soybean
Soybeans are commonly known as soybeans, and farmers have the traditional habit of planting soybeans this year and next year, resulting in slow growth, dwarfism, yellowing of leaves, easy infection of diseases and insect pests, fewer pods and small seeds, and a significant decrease in yield. According to the investigation, in general, the yield of soybean continuous cropping is reduced by 20% to 30% or more, and the main reason for the yield reduction is that diseases and insect pests are prone to several diseases parasitic on soybean, such as bacterial spot, black spot, Rhizoctonia solani, yellow blight and so on. There must be a large number of diseases in soybean continuous cropping soil.

Sowing technology of soybean
1. Soil preparation: (1) soil preparation before sowing: soil preparation before sowing includes soil tillage, raking, pressing, etc. Due to the use of different land preparation techniques, the work of land preparation before sowing is also different. Such as turning over, ridge cultivation, raking stubble, deep loosening and so on. (2) pre-sowing irrigation: for plots with poor soil moisture, if there are irrigation conditions, you can irrigate once 1-2 days before sowing and soak the soil to facilitate seed germination after sowing. (3) closed weeding before sowing: soybean planting in some large farms in the main soybean producing areas of Northeast China.

Key techniques of sowing soybean
1. What key techniques should be mastered in sowing soybean? 1. Choose a place. Soybean should not be selected for continuous cropping, otherwise it is easy to produce diseases and insect pests. After the land is selected, it should be raked up so that the plough layer is soft and the surface is smooth. two。 Seed selection. The varieties suitable for planting in Tiandong are: Beijing beans, Yishan Liula, Guidou No.1, dwarf beans, Binyang small green beans, local soybeans and so on. All localities can choose according to local conditions. Before sowing, choose uniform size, large and full seeds, and dry the seeds. 3. Sow seeds. Early soybeans are sown from the end of February to mid-March

Early control of soybean diseases
If soybean wants to get high yield, it is mainly to solve the problems of "seed, water, fertilizer and light". The cultivation technique of "deep, narrow and dense" is a cultivation model with comprehensive high-yield techniques based on this principle. It takes the selection of dwarf varieties as the breakthrough, the air suction seeder and the general machine as the carrier, combined with "deep" (that is, deep loosening, deep fertilization and layered fertilization), "narrow" (that is, narrow row), "dense" (that is, increasing planting density). It is a cultivation technique with large-scale seeder as carrier. "species" means variety.

Chemical control and management technology of protecting flowers and increasing pods of soybean
1. 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 rare earth solution with concentrations of 0.03% and 0.08% respectively can increase grain protein content by 5.9%, fat content by 8.5%, and increase yield by 15%. 20%. 2. Paclobutrazol (paclobutrazol), also known as chlorbutrazol (PP333), is a new type of plant growth.

Planting technique of 45 cm narrow row dense planting of soybean
The 45 cm narrow row dense planting cultivation technique of soybean is a new technology selected according to the climate, soil and cultivation characteristics of our region on the basis of the narrow row dense planting technology of soybean introduced from Heilongjiang in 2004 in Dunhua City. it is a new breakthrough in the reform of farming system in Dunhua City. Experiments were carried out in Guandi, Heishi and Shaheyan farms in 2005. the average yield of soybean in the experimental area was 202.9 kg per mu, an increase of 24.9% over the control. in 2006, the whole city popularized 1500 mu, with an average yield of 203.52 kg per mu, the highest.

Control measures of three diseases of soybean
Soybean root rot: the disease can occur and cause damage throughout the growth period of soybean, with a yield reduction of 25% to 75% or more. The protein content of the damaged seeds decreased obviously, and the main symptom was that the dark brown disease spot appeared at the base of the stem and spread upward to the lower lateral branches, which made the pith of the diseased stem brown, the base of petiole constricted and the leaves drooping, but did not fall off. The main application of chemical control is 58% Ruidu Manganese Zinc or 72% Kelu wettable powder, the dosage is 0.3% 0.4% seed dressing. Soybean sclerotinia disease

Main advantages of soybean "ridge three" cultivation technique?
The main advantages of soybean "ridge three" cultivation technology are as follows: 1. Soil subsoiling breaks the plough bottom layer, deepens the plough layer, improves the soil structure, is conducive to the development of soybean roots and the formation of nodules, subsoiling forms a soil structure with empty and empty coexistence, and improves the permeability of soil. Second, ridge body layer fertilization, improve the utilization rate of chemical fertilizer, and delay the fertilizer supply time, prevent the late stage of fertilizer loss. At present, the small-sized precision seeder applied in production can apply chemical fertilizer deeply, and can also apply seed fertilizer and base fertilizer simultaneously. Third, ridge soil double strip essence
