First, soil preparation and selection, soybeans are the most irresistible, because: 1 continuous cropping will increase the soil nitrogen and hinder the absorption of phosphorus and potassium; 2 soybean roots secrete an acidic toxic substance, continuous cropping so that soybean lacks molybdenum; 3 soybean diseases and pests With specificity, continuous cropping aggravates pest and disease damage. Therefore, the choice of planted plots should be intercropped or interplanted with grass crops and potatoes. Regardless of spring sowing and summer sowing, sowing and leveling before sowing, apply enough base fertilizer and fill enough bottom water. To use good varieties, after drying, screening and removing impurities, use Rhizobium powder plus 800 times the new high-fat film to spray seed dressing. The planting density should be determined according to the variety, soil fertility, season and other conditions. Do a reasonable close planting.
Second, strong seedlings to promote flowers: After emergence, it is timely to check seedlings between the seedlings to ensure seedlings. Immediately after the seedlings, cultivating and cultivating soil (at least three to four times of cultivating in the whole growing period) will help loosen the soil and promote root development, which is conducive to drought resistance, lodging resistance, and rowing, which will facilitate the formation and development of rhizobia and enhance the ability of nitrogen fixation. In the whole seedling stage, sufficient water and fertilizer are needed, and the NPK proportion and the public opinion must be reasonably matched. The plant should be sprayed with the promotion of Huawang No. 3, and the top of the shoot must be grown wildly to promote the development of flower buds and promote flower bud differentiation. , flower early, flower Qi, resistance to lodging, the formation of high-yield plant shape.
Third, increase pedicle strength: plant growth into the flowering period, to spray the fruit before the flower Zhuang Ti Ling, can spend strong pedicure, enhance the quality of points, to prevent the loss of flower buds and increase flower, increase glutinous, promote Fruit development, no shell, no pods. To strengthen water and fertilizer management at this stage, we must see that the situation of the seedlings is suitable for water and fertilizer, the weak seedlings are topdressed at the beginning of the flowering period, and the strong seedlings are not topdressed to prevent leggy. During the flowering season, appropriate application of phosphate fertilizer should be applied. Irrigate the water in a timely manner to ensure that there is ample publicity. It is necessary to give Daejeon a new high-fat film 600-800 times, prevent transpiration, prevent evaporation, resist wilting, and prevent flower buds from falling off.
Fourth, pest control: soybean pests and diseases on the normal growth of soybean damage, severe loss of more than 30%. Diseases of soybeans include: soybean root rot, nematode disease, gray spot disease, brown spot disease, downy mildew, etc. The pests include submerged root flies, soybean aphids, and borer pests. Control measures: 1 Prior prevention, selection of disease-free varieties Soil preparation and insecticidal treatment during site preparation; 2 Spraying sterilization and pest control agent before the onset of disease + 800 times of new high fat film can effectively prevent the occurrence of pests and diseases; 3 Spray pesticides according to the requirements of plant protection during the period of occurrence of pests and diseases. The new high fat film 800 times kill.
Soybean is one of the most important oil crops, spring or summer sowing. To ensure its high quality and high yield, it is important to plant tubes.
