Triple bean, also known as quadrant beans and algae beans, is a nutritious vegetable crop that is famous for its unique elliptical shape. Its planting methods and timing are essential for high quality production. This paper will provide detailed information on quadrant planting techniques and optimal planting times to help growers better understand the technology. # the bean
I. Cultivation methods
1. Land selection and preparation
The four prisms prefer warm and wet climates, which are less demanding for soil, but are best served by sandy soil that is loose, fertile and well drained. In selecting planting sites, low-lying areas should be avoided and soil ph between 6. 0 and 7. 5 ensured. Before planting, the land should be ploughed deep into the pine soil and applied to sufficient base fertilizers, such as decomposed farming, compound fertilizer, etc., to increase soil fertility。
Seed selection and treatment
Select the large, full, pest-free quadrant seed. Seeds can be tanned for 1-2 days before seed is planted to increase the gestation rate. At the same time, 50 per cent of the seed weight of 0. 3 per cent can be used for wettable powder。
Seeding and density
The planting times of the quadrants varied from late march to early april to mid-may to early june. Seeding can be done live or by planting. At the time of the live broadcasts, the range was 60-80 cm and the range was 30-40 cm, with 2-3 grains per lacuna. At the time of planting, the age of the seedlings was 20-25 days, with one plant per den. Cultivation density is generally contained in 2000-2500 units per acre。
4. Field management
During the growth of the quadrant, weeding should be done in a timely manner in order to preserve soil laxity and reduce competition for weeds. At the same time, in order to be able to catch up on the basis of growth, complex fats are generally followed up once in the periods of seedling and flowering. Attention should also be paid to the prevention of pests and diseases, such as anthrax, rusty, etc., using a combination of chemical and biological control。
5. Collection and retention
Pyramids can be eaten as vegetables and generally begin harvesting 60 to 80 days after seeding. Care should be taken not to damage the plant so as not to affect subsequent yields. When seeding is retained, a strong, pest-free plant should be selected to mature its natural maturity. Premature seeds should be collected, dried and preserved in a timely manner。
Timing of cultivation
The planting time of the prism varies according to regional climatic conditions. In the south, owing to the warm and humid climate, planting can take place four seasons a year, but mainly in the spring. The northern region, for its part, tends to grow only in the spring due to the colder weather. Specific planting times should be considered in combination with factors such as local climatic conditions, soil conditions and market demand。
In sum, the method and time of cultivation of prisms is essential for high quality production. Growers should choose appropriate planting techniques and planting times based on the actual situation, strengthen field management and combat pests and diseases in order to achieve harvests. At the same time, attention should be paid to changes in market demand and prices, and the scale and timing of cultivation should be rationalized to improve economic efficiency。
