Black bean planting techniques
One, timely sowing. Spring sowing in April, in the middle, 5 cm below the ground ground temperature should be 18 ~ C; summer rapeseed in the Yangtze River Basin can also be sown after the harvest; north of the Yangtze River wheat area in the wheat harvest immediately after sowing, should ensure that before mid-June sowing finished.
Two, reasonable dense planting. The variety of species plant tall, suitable for sparse sowing. Medium-fertility fields, spring 1.1-1.3 million plants per mu, high fertility fields about 10,000 plants; summer 1.2-1.5 million plants, sowing late, poor plot should increase the sowing density, 1.8-2.0 million plants per mu. General row spacing 30-40 cm, plant spacing 20-25 cm, 2-3 seeds per hole, 4-5 kg of seed.
Three, field management. Combined with tilling 667 m 2 three elements of compound fertilizer 20-30 kg, 2000 kg of farmyard manure as base fertilizer. After the emergence of seedlings in a timely manner to check seedlings, seed replenishment. Plant height of about 20 cm, each mu of nitrogen, phosphorus, potassium compound fertilizer 15 kg, summer sowing no bottom fertilizer should increase the amount of fertilizer. Plant height of more than 50 cm, the growth of excessive fields with 15% of the multi-purpose azole powder 2,000 times spray 1-2 times, to prevent the crazy growth, the early flowering of 10 kg of urea per mu, and spray concentration of 0.01% -0.05% of ammonium molybdate concentration, in order to reduce the stubble pods shedding, accelerate the expansion of the bean grains to improve yields.
Four, plowing pest control. Pre-growth hard plowing weed control, pay attention to the control of aphids, late attention to the control of pod borer and other pests.
The green kernel black bean planting management method
Variety characteristics
The green kernel black bean is a medium maturity varieties, the plant is tall, strong branching ability, developed root system, steady growth, very spectacular, disease resistance, resistance to collapse. Strong podding ability, pods more grain size, each pod 2 ~ 3, 4 pods accounted for more than 10%, fresh beans weighing 82 ~ 88 grams of 100 grains, dry beans weighing 42 ~ 44 grams of 100 grains, high yield, general mu yield of dry beans about 200 kilograms, high-yield up to 250 kilograms of more than 900 kilograms per mu of fresh soybeans. The seeds are black and shiny, the inner kernel is green and crystal clear, especially for fresh soybeans, the taste is more fragrant, better texture, unique flavor.
Timely sowing
1, selecting the ground sowing: green Ren black bean planting is suitable to choose the soil fertility above the medium, not heavy stubble, not to meet the stubble of the plot. Each mu of high-quality agricultural fertilizer 3000 kg, compound fertilizer 10 to 15 kg to do the bottom fertilizer. Spring sowing in early and mid-April, the ground temperature 5 cm below the ground should be 18 ℃, summer rape in the Yangtze River Basin can also be sown after the harvest, the wheat area north of the Yangtze River in the wheat harvest immediately after the rush to sow, should be guaranteed to be sown in mid-June before the end.
2, sowing density: green kernel black bean plant is tall, suitable for sparse sowing. Medium-fertility fields, spring 1.1 to 13,000 plants per acre, high fertility fields sown about 10,000 plants. Summer sowing 12 to 15,000 plants, sowing late, poor soil strength of the plot should increase the sowing density, 1.8 to 2.0 million plants per mu. General row spacing 30 ~ 40 cm, plant spacing 20 ~ 25 cm, each hole sowing 2 ~ 3 seeds, with 4 ~ 5 kg of seed.
Field management
1, transplanting seedlings to make up for the lack of: Qingren black bean planting in general lack of seedling situation of the plot can be transplanted in situ to replant, transplanting buried soil should be tight, such as soil humidity is small, but also watering, to ensure the survival rate. In order to make transplanting replanting seedlings can grow rapidly, in transplanting after the survival of the appropriate seedling fertilizer should be applied to promote seedling flush, seedling strong. Seedling shortage is serious should be directly replanted.
2, plowing and weeding: Green Ren black beans in 2 single leaf spreading time seedling, the first compound leaf full exhibition period set seedling. When the seedlings should be eliminated weak, diseased and mixed plants, retaining strong plants. The first plowing is usually carried out when the first compound leaf appears and the cotyledons have not fallen, and the second plowing is carried out when the seedlings are about 20 cm tall and the hitching leaves have not closed the rows. The first plowing should be shallow, the second slightly deeper, combined with fertilizer cultivation.
3, timely fertilizer: Green Ren black beans should be combined with tilling mu three elements of compound fertilizer 20 to 30 kg, 2000 kg of farmyard manure as base fertilizer. After the seedling timely seedling check, seed replenishment. Plant height of about 20 cm, per mu of nitrogen, phosphorus, potassium composite fertilizer 15 kg, summer sowing no bottom fertilizer should increase the amount of fertilizer.
4, chemical control treatment: Qingren black bean plant height of more than 50 cm, the growth of excessive fields with 15% of the multi-purpose azole powder 2,000 times sprayed 1 to 2 times to prevent the crazy growth of the early flowering of 10 kg of urea per mu, and spray concentration of 0.01% to 0.05% of ammonium molybdate concentration of ammonium molybdate, in order to reduce the stubble pod shedding, accelerate the expansion of the bean grain to increase yields.
5, disease prevention and pest control: green kernel black beans in the pod period, when more than 30% of the leaves appear spots, with 50% carbendazim wettable powder or 40% carbendazim gum spinner, per hectare dosage of 1.5 kilograms of 500 kilograms of water spraying, can be prevented and treated with gray spot disease. Aphids and red spiders, per hectare with 35% Saidan emulsion 1000 to 1500 ml or with 10% bifenacoum 1500 grams, or with 1.8% avermectin preparation 150 ml, 500 kg of water can be sprayed to control.
