Small grain soybean cultivation techniques

Small-sized soybeans are rich in nutrients and are people's favorite foods. They have higher protein content than ordinary energy soybeans, and the market demand for small-sized soy beans has increased year by year. Small grain soybeans are important materials for export earnings.
I. Applicable varieties:
Seeds are the intrinsic factors that determine quality and yield. Therefore, selection of improved varieties is the primary measure for the production of small-sized soybeans. This year, our town’s promotion variety is: “Jilin Xiaoli No. 3”
The characteristics of “Jilin Xiaoli No.3”: The reproductive period is 110 days and the effective accumulated temperature is 2,100-2,150 degrees, the plant height is 60-65cm, the culm is strong, the branches are numerous, and the three or four grains are mostly populated. , lanceolate leaves, white flowers, round grains, light yellow, colorless umbilical, 100 gram weight of about 7.7 grams of sick grains and worms, generally hectare output of 2000-2500 kg.
Second, the election, soil preparation, fertilization selection: fertility in the upper and middle, the former is corn, potatoes and other cornices, heavy use of ridge before spraying the United States imports of the United States and the "activator" with 3 bags per mu, prohibited sunflower , beetroot sowing.
Site Preparation: Fertilization: Fine seed preparation in spring, fine soybeans “with flaps” unearthed, soil preparation is not easy to cause lack of seedlings and ridges, one-time application of fertilizer must be applied to 20 cubic meters of fertilizer per hectare, and TBS biological fertilizer 200 - 300 kg, 15 kg of biological potassium fertilizer, or 100 kg of diammonium, 50 kg of urea, 50 kg of potassium sulfate, or 100 kg of Spike, 70 kg of urea, all as base fertilizers, and no contact with seeds during fertilization.
Third, drug seed dressing, sowing:
Seed dressing: sowing seeds before sowing, seed dressing with soybean seed ratio of 1:80 for seed dressing to prevent underground pests and prevent seedlings.
Seeding: When the local temperature stabilizes at 8 degrees, (seeing from April 29 to May 1), sowing with mechanical precision sowing or manual isometric on-demand, sowing depth no more than 2-3cm, eliminate large plow deduction.
Sowing amount and reasonable close planting: Do fertility should be diluted, thin ridges should be dense, the general spacing 65cm, seedlings bandwidth 12-15cm, spacing 15cm, 3-4 per plant, seeding amount of 22-25 kg.
Fourth, chemical weeding and auxin application method:
In a timely manner within 3 days after sowing, before the emergence of 25% per toh with 70 grams of soybean meal plus 50% acetochlor 2.5-3 kg or 25% douhoulong 70-75 grams + 50% acetochlor 2.5-3 kg, Or 48% Guang Ling Ling 2 kg, (the best use of chemical weed control Guangling Ling) or 25% of soybean Wei Wei 70 grams +90% Naisi 1.5 kg, watered 300-400 kg of water for spraying.
In order to protect the flowers, promote early maturation, and increase resistance to disease, soybeans will bloom at the blooming stage and the initial stage of flowering. Once per kilogram of Bi Le Bao 1 kg, watered 300-500 kg, or nutrient 30 bags of water 300-500 kg spray.
V. Prevention of pests and diseases:
In the middle of June, the control of locusts began, with omethoate per hectare, and 1 kg of water diverted with 500 kg of water. Anti-sweatworm: In the middle of August, it was controlled by poisonous soil method and sprayed with 1.5 kg of dichlorvos per hectare.
6. The quality of harvesting should be carried out at the end of the mature stage of small-sized soybeans and threshing after 7 days of harvest.
Quality requirements No green beans, no impurities, no pests.

Cosmetics are substances or products used to enhance or alter the appearance of the face or fragrance and texture of the body. Many cosmetics are designed for use of applying to the face, hair, and body. They are generally mixtures of chemical compounds; some being derived from natural sources (such as coconut oil), and some being synthetics or artificial.[1] Common cosmetics include lipstick, mascara, eye shadow, foundation, skin cleansers and body lotions, shampoo and conditioner, hairstyling products (gel, hair spray, etc.), perfume and cologne. Cosmetics applied to the face to enhance its appearance are often called make-up or makeup.
