In the spring, in huanqing district, chongqing city, four seasons of soybean production technology
Four seasons of beans, alias bean, beans, lentils, beans, etc., are widely distributed in the country. Its bean is fat, delicious and nutritious and is one of the vegetables common on the table. The four-season bean production cycle is short, low in investment, easy to manage, high in output, high in efficiency and high in market sales, and in recent years many farmers in huanzhou, chongqing city, have begun to grow in large quantities, with good economic benefits。
Four seasons of beans have developed roots (mostly in 15-30 centimetres of the earth's layer, with a root depth of 70 centimetres or more), with a large number of root roots with strong nitrogen fixation capacity. The appropriate growth temperature is between 20 and 25°c, the temperature is less than 12°c or more than 30°c is stunted, vines and vines are growing slowly and, in some cases, flowers are falling and quails are falling. During longer periods of light, the production of vines and vines accumulate more nutrients, and the number of flowers and masons increases. It is important to ensure sufficient soil moisture in day-to-day management, given the long season bean vines and the large number of leaves and evaporation levels. In addition, there is a greater demand for nitrogen and potassium。
I. The bean species selection
The selection of high-yielding four-season bean varieties that are viable, well developed, viable and hot and wet, depending on local natural and climatic conditions, should also take into account market outlets. The species of bean bean is generally selected with a width greater than 0. 8 cm and a length greater than 14 cm, a bright colour, a low concentration of crude fibre and a concentration of flowers。
Land selection
The selection of plots that are front-loaded with non-beans crops requires thicker, loosely fertilized, well-ventilated, easy to drain, and higher nitrogen and potassium content in the soil. Cultivating four seasons of beans on plots that have been grown with pulses can cause severe pests and pests, high production costs, low soybean quality and low yields, affecting economic income。
Iii. Complete production
Prior to the application of 2,000 kg per acre of manure from decomposed livestock + 20 kg of calcium perphosphate + 10 kg of ammonium sulphate + 10 kg of potassium chloride, the soil was ploughed with a microcroper to level the soil and to level the soil. When the soil is poor, proper water or irrigation is required to ensure that the soil contains 60-80 per cent of the water in the field. Finally, the compartments are open at 150 cm width and awaiting seeding。
Iv. Sowning
In huanzhou, seeding began in early march. Before seeding, four season bean seeds are placed in the sun for three days in order to break their hibernation; then they are immersed in warm water at 50°c for four hours, so that the seed can suck up its moisture to accelerate the germinate. Seeds are then dryed and pelvis are distributed at a distance of 15 cm and 60 cm, with 3 to 4 grains per den at a depth of 2 cm, which is then covered with fine soil. After five to seven days, the seed will appear from the ground and, in order to accelerate the growth of the seedlings, it will be possible to water the scavengers once. It is important to note that chemical fertilizers are not applied directly at this time, otherwise they are easily burned to death。
V. Field management
1. Pine weeding
After four seasons of soybean seedlings, small weeds will continue to grow in the ground, and at this point they will have to do good shallow earthworks, cutting off small weed roots and causing death due to lack of nutrients; and they will be able to decompress the soil and increase the oxygen content. When weeds have one heart, i. E. A 3% methyl-disulfon-oil suspension of 28 ml/acre and 30 kg of water diluted, sprays are sprayed in the space of the bean line in order to eliminate monoleas and promote the rapid growth of soya seedlings。
Watering
According to the four seasons of soybeans, in the event of dry weather, water should be poured in time to keep the soil wet; if the weather is not dry, water is not required. During the flowering period until the end of the term, the soil is more water-consuming, and the amount and frequency of the water should be increased as appropriate; the soybeans must be guaranteed to be watered once in four days as long as they reach 5 cm。

Fertilizing
During the four seasons of two pairs of seedlings of beans, 800 kg/acre of defecated manure was used to promote the rapid growth of seedlings. When buds appear on vines, 8 kg/acre urea is applied to promote rapid growth of buds. During the flowering period to the end of the acupuncture, three dollar complex fertilizers (15-15) 5 kg/acre were imported; at the same time, 0. 3% of the potassium phosphate solution was sprayed on the leaves, and the protection of flowers and acupuncture improved the quality and production of bean beans。
4. Arguments
When the four-season bean seed grows to 40 centimetres high, it starts to build up, choosing a two-and-a-half metre thick bamboo pole, three for each of the poles, slashing the pole onto the ground, crossing the top of the pole with a thin line. Tied together to make the stairwells a “tip” to improve their stability. Then we'll draw the vines to the bamboo poles and we'll use straw. Tie the vines to grow upwards around the bamboo poles and ensure good ventilation within the racks in order to facilitate the continuous stretching of the vines。
5. Pest management
The four seasons are characterized by a high incidence of chronic diseases and pests, which require constant preparedness. Anthrax with 70 % of alpha-based fungus, wet powder 1,000-1200 times liquid spray, rust with 25% triazine humid powder 1,500-2,000 times liquid spray, vegetable with 40% thiphos-methyl emulsion 1,000-1200 times liquid spray, and moth with 50% dan soluble powder 800 to 1,000 times liquid spray, 1. 8 per cent avulse cream 3,000 to 4,000 times liquid sprayed in a leaf fly and 10 per cent acne wet powdered 1,500 to 2,000 times liquid sprayed in beans。
Collection
1. Picking of beans
When the bean is grown to 10 cm long, the harvest begins, one hand grabs the bouquet and the other bends the bean down to 90°, so that it cannot be pulled to the ground, otherwise the vine will be torn to death. After extraction, bean bean is packaged for sale in a timely manner and not at home; otherwise, the soya bean is severely lost, affecting its value。

2. Picking of beans
When the shell of the bean is yellowened, the bean bean is harvested, the bean is picked with full grains of beans, free of pests and diseases, and is tanned in a timely manner, removed and stored in a warehouse to prevent deterioration and infestation。
