When is the season for planting in Beidahuang?

Beidahuang started planting in early May.

The main crops in Beidahuang are: soybeans, corn, rice, etc.

Soybean Cultivation Technology

Temperature Requirements

Soybeans are temperature-loving crops. The minimum temperature for germination is 6°C, the seedling temperature is 8 to 10°C, and the seedling temperature is 0°C 4 If the temperature is below ℃, it will suffer slight freezing damage. The optimal growth temperature of soybeans is the daily average temperature of 20 to 25°C, of ??which the optimal growth temperature for seedlings is 20 to 21°C, the flower bud differentiation stage is 21 to 23°C, the flowering stage is 22 to 25°C, and the pod and grain period is 21 to 23°C, and the maturity period is 19 to 20°C. The accumulated temperature requirement is 2400 to 3800℃.

Deep fertilization

Fertilization method: Under normal circumstances, the fertilizers are separated from the seeds and applied 4 to 5 cm below the side of the seeds. The amount of fertilizer can be adjusted. When applying more than 20 kilograms of diammonium phosphate per acre, it can be applied in layers: the depth of the upper layer of seed fertilizer is 5 to 7 cm, and the fertilizer amount accounts for 1/3; the depth of the base fertilizer is 10 to 16 cm, and the amount of fertilizer accounts for 2/3. Or after the previous crop is harvested, spread the fermented organic fertilizer evenly on the surface, then use a rake to rake the fertilizer into the soil, mix the fertilizer and soil thoroughly, and then plow deeply. After plowing, rake the bottle to create fine ridges. Soybeans can be planted flat.

Precision sowing

Reasonable crop rotation: It is best to choose the right stubble, not heavy, and plant in the next stubble.

Careful soil preparation: Carry out late-autumn plowing according to the previous crops, with a depth of 22 to 25 centimeters. During the operation, there should be no large clods of soil, no clear strips or lumps, and the soil should be buckled tightly and not heavy or leaky.

Soil moisture: The soil moisture content (dry soil weight%) after soil preparation should be about 22% when sowing to ensure that the seeds can absorb water and germinate normally.

Sowing at the right time: Summer soybeans can be sown after the wheat is harvested, as long as the moisture is suitable. The best sowing period is from June 10th to 25th, and no later than early July.

Field management

Hoeing and cultivating:

⑴ Hoe all over the ground before the first compound leaf, so that the seedlings can be cleared of grass and grass without damaging the seedlings. Loosen topsoil.

⑵ When the seedlings are about 10 cm high, perform the second cultivating to ensure that the seedlings are not damaged, pressed, or grass leaked.

⑶ About 10 days after the second cultivation, the third cultivation should be carried out to deeply loosen and cover the soil.

Pre-emergence weeding: The most commonly used spectral herbicides in production are Pusite and clomazone. These two herbicides are effective against a variety of grass weeds and broadleaf weeds in soybean fields. All valid. Dosage: 5% Pusite aqueous solution, 1.5 to 2 kilograms per hectare; 48% clomazone EC, 2 to 2.5 kilograms per hectare. Pusite, bensulfuron, and clomazone can all remain in the soil for a long time, so special attention should be paid to the damage to subsequent crops.

Post-emergence weeding:

⑴Types of herbicides Herbicides suitable for early emergence: The most commonly used herbicide in production is Pusite. Apply pesticides when weeds are just emerging, generally no later than the second compound leaf stage of soybeans. The dosage of Pusite applied in the early stage of emergence is: 1 to 1.5 kilograms per hectare of 5% Pusite aqueous agent, and should not exceed 1.5 kilograms. It should be applied in weather with high humidity before and after rainfall, and avoid hot and dry weather at noon and windy weather.

⑵Usage 12% of Nana Net Emulsion, the dosage per hectare is 1 to 1.5 kg; 15% of refined grass, the dosage per hectare is 0.75 to 1 kg; 5% of refined grass Gram EC, 24% Gram EC, the dosage per hectare is 0.33 to 0.75 kg.

(3) Application period Herbicides suitable for the late emergence stage are generally applied at the 2 to 3 compound leaf stage of soybeans. In years with good soil moisture in spring, pesticide application can be done earlier, and the lower limit of pesticide dosage is generally used. If there is a drought in spring, pesticide application can be done later, and the upper limit of pesticide dosage is generally used.

Summer sowing technology

Irrigation before sowing: For plots with poor moisture and irrigation conditions, you can irrigate once before sowing to facilitate seed germination after sowing. Combined with irrigation, field closed weeding is carried out.

Sowing date: Since the growing season of summer soybeans is short, it is important to sow them early and at the right time. Sow seeds at the right time, with high seedling preservation rate, neat and strong emergence, and strong stems.

Rational dense planting: Reasonable dense planting means correctly handling the relationship between individuals and groups under the specific local and prevailing conditions, so that the group can develop to the maximum extent and the individuals can fully grow; Light energy and soil fertility are fully utilized; under the same cultivation conditions, the best economic benefits can be obtained. It can be sown on the ridges of fields, which can increase the sowing area and make the soybeans taste better.

Autumn sowing technology

Soil preparation: After the rice fields are plowed, they are divided into compartments. The width of the compartments is 2 to 3 meters, the row spacing is 3 meters, and the hole spacing is 0.33 meters. There are 2 to 3 seeds per hole, and the density is about 30,000 plants per acre.

Timely sowing: Generally sow before August 10, with a seeding rate of 8 to 10 kilograms per acre.

Reasonable fertilization: use 25 kg of calcium, magnesium and phosphorus fertilizer per acre mixed with 500 kg of soil fertilizer as cover seed fertilizer; topdress 3 to 5 kg of urea per acre during the early flowering period depending on the seedling condition, and 2% during the pod setting period. Use 40 to 50 kilograms of superphosphate clarified solution per mu, and 30 to 40 kilograms of ammonium molybdate 0.05% concentration diluent per mu. Mix the two and spray them on the leaf surfaces; or spray 0.1% borax solution on the leaf surfaces to improve the quality of the leaves. Kernel fullness.

Field management: When encountering high temperatures during sowing, watering should be done first and then watered. If there is insufficient water after sowing, water can be poured in the evening.

At the 3-leaf stage and time seedlings, the general seedling density is 30,000 to 40,000 plants per acre. After the seedlings are established, 6 to 8 kilograms of urea per acre are applied in a timely manner. Timely cultivating and weeding, generally 2 to 3 times of cultivating and weeding, and soil cultivation is also required.
