Black soybean cultivation points

[ Agricultural Products Network] The development of black agriculture is an important part of the city's adjustment of agricultural structure and breakthrough projects, of which the benefits of black soybeans are relatively good. According to Hechuan years of experience in planting, black soybean cultivation technology get better the following:

First, the selection of good varieties: the city's recent experiments show that the suitable planting of Minnan black beans (through the urban test in Chongqing showed a plant height of 58.68cm, the initial pod height of 16.72cm, the number of branches is 2.53, the number of main stems is 9.65, 21.72 pods per plant pods per plant 43.55, 5.60 pods three pods, seed weight 22.49g, theoretical yield 163.8kg / mu, the actual yield of 146.5kg / mu, the growth period of 106 days.), Xinong Fine varieties such as black beans.

Second, the Land selection: general space, young fruit forest, to the young mulberry, citrus grafting farming, "four sides", the low and high areas corn fields Y, Wang Amada, are suitable for planting.

Third, the farming system: young fruit woodland, high Y Tian, Wang Tian Tian and so on, can be implemented beans - beans farming system, or beans - vegetable farming system; viable wheat Maize earth - beans - beans, wheat - beans - potato, wheat - jade - vetch // beans farming system.

Fourth, Sowing: In order to improve convergence Crops, does not affect the sowing of the crop after crop, must timely early sowing. However, this year's ZUI drought in the spring is more serious and should be treated differently.

Spring sowing is generally carried out by live broadcast. When the average daily temperature is stable through 12 °C, it can be planted. It is appropriate to plant in late March (the sowing period test in Weinan County and the trial test in our city), ZUI is not more than mid-April. If there is a field block guaranteed by water source, it should be sown on March 20; otherwise, it should be caught in the sunny weather after the rain.

V. Planting and sowing specifications for land preparation: Early excavation of bauxite, flattening the land and then sowing. The specifications are 25 cm in pitch, 33.3 to 40 cm in row spacing, and 6500 to 8000 nests in acre. The soil is slightly thin and the soil is slightly dense. 5 to 6 capsules are planted in the nest, and 5 to 6 kg are used in the acre. After sowing, 20 kg of calcium magnesium phosphate fertilizer and 5 kg of potassium fertilizer (or 100 kg of grass ash) are mixed with fine soil cover.

6. Field management:

1, uniform, fixed seedlings: after emergence, should promptly check the seedlings to fill the gap, evenly seedlings set seedlings, go weak and stay strong, nest two plants.

2, formula fertilization: seedling period (20 ~ 25 days after sowing), the use of 35% BB fertilizer 20kg or soybean special compound fertilizer 25kg nest; flowering pod-forming period, acres with borax 100 grams of water for root spray Shi. Simultaneous cultivating and weeding.

3, prevention of pests, rabbits , rats, hazards: 20 days after seeding, killing 10ml with the enemy or 150 grams of Omethoate with water spray to control the silkworm and caterpillar. At the same time, pay attention to the prevention of wild rabbit snapped tender heart. Acre with insecticidal double 150 ~ 200 grams or 50% methamidophos 100 ~ 150 grams with water spray to control aphids, bean fly. In the later stage, white ash was used to control rodents, and baits were used to trap mice and hares.

Seven, timely harvest:

When the leaves of the beans are yellow and the plants are all broken, 80% of the pods are dark brown, and they are harvested on sunny or cloudy days. Use a quick shovel to cut, thresh, spread, and clean the bag after storage. For example, selling hairy (green) pods can be sold after the drums.

When harvesting, the strain cannot be removed, and the rhizobium is left in the soil. Harvest the leaves (the leaves are the high-quality feed for the pigs ), bundle them into small pieces and transport them back to the shelter from the rain, let them cook, turn the sun and thresh. After the harvest, you can seize the favorable opportunity to plant in the fall.
