What is the outlook for black beans? The main planting areas of black bean planting areas are Heilongjiang, Liaoning, Jilin, Anhui, Henan, Hebei, Shandong, and Jiangsu. Today, the price of black bean seeds is in the range of 7-10 yuan/kg, and the retail price is 8-12 yuan/kg. Let's talk about the black bean planting time and technical points in detail, and hope to help everyone. First, black bean sowing, harvest 1, sowing (1) Black bean growth habits: like warmth and high temperature resistance. (2) Suitable temperature for growth and development of black beans: 18-30 degrees. (3) The seeding method is best to breed with large and full particles and bright black hair. (4) Start seeding when the soil temperature is 10-12 degrees. (5) Using the method of hole sowing, the row spacing is 27-33 cm, the hole spacing is 17-20 cm, three or four seeds are planted per hole, and the soil is covered with 3-4 cm thick after sowing. (6) Planting density should be determined according to the characteristics of the variety and water and fertilizer conditions. (7) Early maturing varieties: 3-4 million plants are planted per 667 m2. (8) Medium-maturing varieties: 2.5-3.5 million plants are planted per 667 m2. (9) Late-maturing varieties: about 20,000 plants are planted per 667 m2. 2, harvest (1) The film was uncovered in mid-August. (2) When the leaves reach 90%, the goods can be received. (3) When harvesting, mechanically combine harvesting, (4) When all the soybean leaves are returned to the garden, they are carried out. Second, black bean planting technology (1) The depth of sowing of black beans The depth is 3-4cm, which can be slightly deeper for spring drought, windy, loose soil or poor moisture. (2) Black bean cultivation density According to the characteristics of the variety, natural conditions, soil fertility and cultivation methods, the general seeding rate is 70-90kg/ha. (3) sowing The compound fertilizer was layered and applied to the seed 8cm and 12cm under the seeding machine with a fine seeding machine; (4) Seeding and fertilization amount The amount of fertilizer applied is 100-120kg/ha. (5) Land parcel requirements A plot of well-drained, fertile soil with irrigation conditions. (6) Soil preparation and fertilization Mainly in the spring land preparation, intensive cultivation; Before the sowing, a fully decomposed high-quality farmyard manure of 30 tons/ha was applied. (7) Increasing the ground temperature, storing water and protecting the weeds, eliminating weeds, and enhancing the activities of soil microorganisms, spraying 1% urea solution and 0.2% dihydrogen phosphate on the leaf surface at the initial flowering stage and the drum stage of black beans. Potassium aqueous solution. (8) In the flowering and pod-forming period, if it is drought, it should be irrigated 1-2 times in time, which is conducive to the fullness of black bean seeds. (9) Locust control Control with 10% imidacloprid 1500 times spray. (10) Gray spot disease prevention In the early stage of gray spot disease, it was sprayed with 40% carbendazim 300 times solution. Another benefit of vitamins for the human body is that it can help the growth and development of the human body to operate normally, especially for teenagers, vitamins are one of the essential nutrients in the growth process. For example, vitamin D can well adjust the metabolism of some trace elements in the human body, and can also promote the absorption of calcium by the human body, maintain bone health, and maintain a balance between the blood phosphorus level and the blood calcium level in the human body.
