The soybeans, also known as soybeans, contain rich plant proteins and a variety of minerals and vitamins of human benefit. At the same time, because of the low use of pesticides in the production process, they are the preferred species for the production of non-publicly hazardous vegetables. Potatoes are warm crops, they begin with 10-11c and are at 20-22c. From mid-february to the end of may, seed can be planted and harvested for about three months at 600 ~ 700 kg of cyanide per 667 m2。
1. Choice of varieties
The main varieties of soybeans planted in the city are the great particle king, no. 3, and no. 9. (a) the king of large grains: the leaves of this type are dark green, the ellipses of the leaves are thick, the branches are strong, they are straight and they are 55 cm tall. Flour, bean-fruit white, green green green, seed seed pellets, yellow turquoises, large, 100 grammes. The varieties are wide-spread, cold-resistant during the seeding season, and the low-temperature growth is suitable for early transmission. The species matures very early, from seed to pickling 55 ~ 58 days in the yangtze river basin and 90 days of total fertility。
Fertilizing the whole area
Ph of 6 ~ 7. 5 is selected for deep earth layer, soil dysentery, water preservation, permeable sandy or light border soil. The entire pre-winter layer is vertebrateed and is applied to base fertilizer at 1,500 ~ 2,500 kg per 667 square metre of decomposition farmer fertilizer, which is to be broadcast by 1. 5 to 1. 8 metres。
Sowing
(1) season: protected land is planted from mid-february to early march, and field is available from mid-march to the end of may。
(2) seeding: the selection of seeds with no moths, no cartilage, no damage, full seed, with the first one to two days of sunbath, followed by key fattening, root tumor seeding, can increase production by about 15%. The seeding period runs from mid-february to the end of may, with on-demand seeding of between 3-5 and 5 cm per den, which is then covered with wet soil. Scrolling specifications: the range of long-finished varieties, such as the big particle king, is 22-24 cm square, and the range of medium- and late-finished varieties, such as the quantified 9 is 30-33 cm square。
4. Field management
(i) pre-emergence: take care of the pine-earth seedlings, prevent suffocation after the rain, and use grass, acetamine, etc. For pre-emerging chemical weeding。
(ii) shrimp period: first, shrunk and replanted at time. Second, chinese weeding usually takes place twice during the sapling season, the first of which should be considered as early as possible, at the right time, and the second at the height of 10-13 centimetres, with the possibility of chemical weeding by weeding. The third is to see the seedlings chasing fat, which is usually not. Under conditions of insufficient soil fertility, 3,5 kg of urea, 7 ~ 15 kg of calcium perphosphate and 15 ~ 20 kg of potassium fertilizer per 667 m2. The fourth is timely impregnation, with care to combat tigers, eels and aphids。
(3) late mid-term: first, weeding and drought resistance and drainage are done in order to prevent the drying of the soil, which would otherwise affect the thawing of the flowers, resulting in a decrease in flowering and the falling of the bouquets. The second is the incidental pursuit of flowering fertilizers, with 5 ~10 kg of urea, 15 ~20 kg of calcium perphosphate, 20 ~25 kg of potassium fat, boron and potassium fat per 667 m2. Third is to prevent protege, which can be controlled by contusions。
5. Disease control
The soybeans are the main pests of soybeans, soybeans, and soybeans. The soybeans can be watered 1-2 times during their flowering season, killing human larvae. For larvae, 40 per cent of the larvae milk is treated with 1000 times more liquid or 50 per cent of the marathion emulsifiable spray. Yellow strips are mainly harmful leaves and can be sprayed with 1000 times more liquid dichlorvos. The disease of the beans is mainly rusty. Rusty disease control is first based on the use of non-pathological seeds or their disinfection; second, rotation is introduced to avoid heavy stress; and lastly, at the beginning of the disease, 600 times more humid powder sprays, two sprayings for the seeding period and two to three sprayings for the endurance period, five to seven days apart, can be avoided with 65% rusty luminous powder or 75% bacteria。
6. Collection
Pre-cooked varieties tend to be marketed in the morning, i. E. After the drum season, and can be harvested at good prices, but not too early, otherwise the small grains of beans, the poor commodity nature and the low yields reduce economic benefits. When seed grains are full, they are not yet turned (white) colour, and the surrounding garments are fully ploughed in a timely manner。
This is all of today's content, and growers can refer more to it, or they can comment on what they want to know about the three agricultural techniques, and they can make it easier for them to do so. It's not easy to create, and i'd like you to look at the writer and forward the positive comments. Thank you
