1.Select good varieties
Good varieties of beans should be selected for selection in the greenhouse. Due to the small resistance of the seeds of beans, the seeds should be carefully selected before sowing, with the whole seedlings and strong seedlings as the prerequisite for cultivation. In the past, most of the cultivation methods of beans were direct seeding. In recent years, with the rise of greenhouses, the cultivation of beans in the greenhouse should be transplanted to protect the root system from damage. The continuous improvement of agricultural technology has led to a variety of current beans, including red beans, skin beans, local beans and hybrid beans, etc. Growing beans in a greenhouse requires reasonable cultivation in accordance with the local planting conditions. Generally, We can choose 2 or 3 varieties with relatively high cost performance for mixed re-compensation. This will increase the yield to a certain extent, and we can also cultivate new varieties of beans and supply market demand. Green beans are grown in greenhouses, which is convenient for up-and-down inspections. Not only can they be planted early, harvested early, and marketed in advance, they can also ensure that the whole seedlings are strong, thereby promoting flowering and pods, and increasing the yield of beans. Available in 15 days.
2.Soil preparation
Beans have deep soil. If you want high yield, it is best to choose soil that is fertile and not easy to accumulate water for sowing. Before sowing, it needs to be turned deeper by 25 cm, combined with ground plowing and applying soil of about 5,000 to 10,000 kg, superphosphate or diammonium phosphate, and potassium fertilizers are mixed in proportion with the soil and thoroughly turned. Of course, we can also use soil fertilizer or livestock manure as the main source, and configure points by ourselves. The average application rate is about 3000 kg per mu. In wetlands, soil treatment can also be combined with microbial agents, which can prevent the reduction of soil infectious diseases and insect pests. Although greenhouse beans can be planted throughout the year, it is best to choose sowing in April each year to achieve high yield and high quality.
3. Water and fertilizer management
Bean roots are deeply drought-resistant and grow vigorously, and are more prone to signs of excessive nutrient growth than other legumes. The greenhouse is weak in light, high in temperature, and rich in fertility, which is more suitable for the growth of beans and affects flowering and pod formation. In the field management, you must control before you promote to prevent stems and leaves from growing too long or premature senescence. From transplanting to flowering, we mainly control water-cultivating thick heels, and carry out proper squatting to promote flowering and pod formation. When the bean seedlings grow to about four or five centimeters, we need to water them and let it Fully absorb water and grow quickly; After the pods are set up, they should be fully supplied with fertilizer and water to increase the number of flowering and pods. When the carob seedlings grow to about 20 centimeters, we need to perform a field tiller and weeding together with fertilization. If the growth is poor, you can use it The carbohydrate and seaweed probiotic mother liquor is applied to protect the body temperature, promote root development, control stem and leaf length, and take roots. When flower buds appear, reduce the amount of watering, and then plant it. It is not easy to water at the early flowering stage. Wait until flowering before fertilizing, spraying mainly with potassium and phosphate.
4, pick leaves and sparse flowers
There is another way to increase the yield of beans. When the beans are in the flowering period, appropriately remove some of the weak flowers and flowers damaged by pests. This will not only reduce the loss of nutrients, but also prevent the loss of nutrients. Falling flowers minimize losses. You can also use scaffolding. Everyone is also very important to increase the yield of beans. If you do n’t carry out scaffolding, let it grow freely. The growth of beans is slow. So we can generally treat the beans when the seedlings grow to about 30 cm. Manage scaffolding. At the same time, you can also hold the bean sprouts frozen by hand, and let it grow along the shelf to increase the yield.

Rhodium powder Rh≥99.95% Properties: silver-white metal, extremely hard, wear-resistant, also has considerable ductility Application: It can be used as raw material for electrical instrumentation, chemical industry and manufacture of precision alloys. Rhodium powder is based on the widespread use of ruthenium in the industrial industry. Since rhodium is a rare metal required by the industry, the industry price is slightly higher than that of general non-ferrous metals. Rhodium, one of the rare elements, has various uses. Rhodium can be used to make hydrogenation catalysts, thermocouples, platinum-rhodium alloys, etc. It is also often plated on searchlights and reflectors, and is also used as a polishing agent for gemstones. and electrical contact parts.
