I. Selection and Land Preparation
1. Election: The implementation of rotation for more than three years, so that it is not heavy, not smashing, the former scorpion is better with corn and wheat glutinous rice, and requires that the sorghum is preferably not applied to high-toxic, high-residue pesticide plots, medium fertility Piece.
2, the preparation of the land: wheat 茬 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋 秋Site preparation quality: The ploughed soil is finely divided, loose, and the ground is flat. The height difference between the height of 10 meters is not more than 3cm, and the number of soil blocks with a diameter of more than 5cm per square meter is no more than three, which is suitable for broadcasting.
Second, the seed
1. Variety selection: Select excellent soybean varieties with high quality, high yield and strong resistance to the main stem type pod-forming habits, tolerant to barrenness, and to produce special varieties. Such as: 垦 豆 27 27, 垦 豆 豆 28, Heihe 43, Beifeng 11, and so on.
2, seed production: the implementation of seed specialized production and processing, the farm seed company unified seed.
3. Seed selection. The seed reached the grading standard of two or more, namely: the netness reached 99%, the purity reached 98%, and the germination rate reached over 95%.
4, seed treatment: the use of pesticide dressing, control soybean root rot and gray spot disease. One hundred kilograms of seeds were mixed with 50% carbendazim WP and 50% thiram WP, each 0.15 kg of water and 1 kg of wet seed dressing.
Third, sowing
1. Sowing date: When the soil temperature is 5-10 cm and the temperature is stable through 5C°, seeding starts and is broadcasted before May 10.
2, the broadcast method: the ridge distance of 110cm, 3 rows of fine on-demand technology on the ridge.
3, sowing depth: after the suppression of the post, the depth of the sowing is 4cm - 5cm, and the depth of the sowing is 3cm - 4cm.
4. Density: Seeding and density should be determined according to the variety and soil water and fertilizer conditions. The density is 350,000 plants per hectare.
5, sowing quality
(1) The seed fertilizer is divided into boxes, not mixed, and the seed fertilizer is not contacted after sowing.
(2) Uniform sowing (no break within 20cm), strict, timely suppression after sowing. The total broadcast volume error does not exceed 2%, and the single-port flow error does not exceed 3%
Fourth, fertilizing
1. Base fertilizer: After harvesting the crops of the previous year, the straw smasher brought by the harvester is used to return the straw to the field, and then smashed and evenly sprinkled on the ground.
2, seed fertilizer: fertilizer to do seed fertilizer, ammonium phosphate ammonium 97 kg / ha, urea 63 kg / ha, applied to the seeds below 5cm, avoid the same place of fertilizer, so as not to burn.
3. Foliar fertilizer: At the initial flowering stage of soybean, 10 kg of urea per hectare, plus 2.25 kg of potassium dihydrogen phosphate, 3 kg of Huimanfeng, 300 kg of water, and foliar spray.
4. Fertilization method: In order to improve the utilization rate of chemical fertilizer, adopt autumn fertilization and stratified deep application. The method is as follows: fertilization is divided into upper and lower layers, and upper layer (fertilizer) is applied to seeds under 3-5 cm, and the amount of fertilization accounts for the total amount. One third; the lower layer (bottom fertilizer) is applied to the seed 12-15 cm, and the fertilization amount accounts for two-thirds of the total amount, which is combined with the autumn ridge.
V. Field Management
1. Deep pine: The ditch is deep and loose, and the depth is not to stick to the stick and the large clods as the standard. Live the soil and raise the ground temperature.
2, cultivating management: weed control using integrated grass control technology: manual weeding three times, artificially take the grass once again, so that the grass is not seen. The machine is cultivated three times, the second pass is 15cm deep, 10 days apart, and the third pass is 10-20cm deep. The fourth pass is carried out before the soybean is closed and the soil reaches the cotyledon mark.
3, chemical weeding: all autumn medicine, with Jinduer 1.2 liters / hectare + trifluralin 1.51.2 liters / hectare + treasure 30 grams / hectare or fast harvest 150-180 g / ha or Sike 0.4 kg / Hectare. Stem and leaf treatment can also be carried out by using herbicides such as saponin, bentazone, quizalofop, and flufenazone.
4, pests and diseases control
Pest control principles: mainly agricultural control, physical control, ecological control, biological control, supplemented by chemical control. Through the selection of disease-resistant varieties, crop rotation, cultivation of strong seedlings, intensive cultivation and other agricultural measures, using physical measures such as lighting, color trapping, mechanical artificial capture of pests, selection of low-toxic biological pesticides, release of natural enemies and other biological measures, limited application of limited Chemically synthesized pesticides, each pesticide is only allowed to be used once during the season of crop growth. The pesticide meets the NY/T 393-2000 standard and reduces the pest damage to the minimum allowable value.
5, disease prevention and fitness to promote early maturity technology application: aircraft aviation sprayed potassium dihydrogen phosphate 3 kg / ha to promote early maturity, according to the forecast situation to control soybean heartworm.
VI. Harvest
(1) Harvest period: When the soybean leaves fall, the seeds are full and return to the garden, the ringing bells can be heard, and the grain moisture reaches 15% or less for mechanical combined harvesting.
(2) Harvesting requirements: cutting mites should be low, no branches, no pods, and the loss rate is less than 2%. Single harvesting, single pulling, single stacking, and single storage ensure the quality and quality of Grade A green food soybeans.
