The late planting of the soybeans in the autumn has led to more favourable environmental conditions, less difficult cultivation and easier access to high yields。
Seeding
Diversity selection. Depending on local climatic characteristics and consumption habits, it is advisable to use pre-heat-resistant and later cold-resistant varieties such as thiram 28-2, thiamin 512, thiram 3, thiram 3。
Pick the ground. In the fall, the production of the soybeans was delayed, with the combined use of sunnets, insecticide-treated nets and large filaments. The soybeans require less stringent soil requirements, but they are suitable for deep, fertile, soft, well-drived, well-ventilated sandy or bordery soil. The bean horns are used to choose fields that have not been grown for three years. At the time of the conversion, 5,000 kg of corroded organic fat, 25 kg of cake fat, 50 kg of triple compound fat and 50 kg of calcium per phosphate were applied per acre. Drumbs, full of high-level tacks, 1 to 1. 2 metres wide and 25 to 30 centimetres deep in ditches to drain water. The surface must be flat, and there must be no big dirt。
And sowing in time. In the autumn, the delay in the soybeans cultivation was generally broadcast live in early august. Early seeding occurs at a time of high summer temperatures, which can lead to the fall of flowers; the planting is too late, the temperature falls, the soybeans grow slowly and yields fall. The seeding was done on a shallow basis, with two lines per soak, approximately 35 centimetres away, three to four seeds per den, 2,700 to 3,100 acres and 1. 5 to 2. 5 kilograms per acre。
Field management
Cover the worm net. Aphids and soybeans are the main pests in production during the fall-delayed cultivation and must be given high priority and isolated from the nets. Before seeding the beans, the nets should be installed as soon as possible and their density must not be less than 30 m. Once the net is covered, the aphid is sprayed quickly to protect the seedlings from the pests。
Fertilizer management. The roots of the bean are well developed and are therefore more drought-resistant. The general principle for the management of the fatty of bean bean bean bean is that it is the top and the bottom. Pre-preventive prototyping and post-preventing premature decay. It should be properly controlled and contribute to the formation of more bouquets, but it should be properly watered to prevent atrophy as the roots are still at the surface of the system during periods of high temperatures and drought. In flowering seasons, bean bean horns need a lot of fat. In the centre of the chicken shelf, flowers have been blooming and the bottom is fertilized once when it reaches about 10 cm. Each acre is filled with 10 to 15 kilograms of fertilizing water in a sunday afternoon ditch. The harvest period, starting with the first harvest, is fertilized about every seven days and is followed up twice to promote acupuncture and to prevent premature decay. For each acre, 10 to 15 kg of flushing fertilizers are used to fill a ditch. Since the requirements for fertilizers are the highest for phosphorus, the second highest for potassium and the lowest for nitrogen, in addition to the need to supplement certain nitrogen fats due to insufficient growth of root tumours during seeding periods, the flowering season is dominated by phosphorus and potassium fertilizers, which promote the activity of root tumours, so that the plant is robust, flowering and corrosive。
Hit the top. When the chicken reaches the top of the shelf and has returned to about 30 centimetres, the top should be cut off in time to prevent interlocking and influence ventilation. Up tops can effectively control nutrient growth, promote chromatization of the lower part, increase the number of flowers and increase the rate of ferns。
Keep it warm. Since mid-september, when cold air is prone to attack, which affects the normal growth of bean bean bean horns, it is important that the shacks be kept in time to prevent cold. After the lid, if it's clear, the shed is open during the day and is covered at night. In the case of a rainy day, the night and day are not open. Controls are around 30°c during the day and 20°c ~ 25°c at night。
Collection in due time
Autumn delay bean horns are collected between 38 and 50 days from seeding, and between 8 and 12 days from flowering to seedling. Seeds should normally be harvested at the beginning of their expansion, ensuring that bean bean bean bean is strong, thin, easy to transport and yield。
