The adaptability of the beans is strong. It can be cultivated in the open field as well as in the protected land. It can also be produced in the year and listed in the four seasons. It is one of the popular vegetables widely cultivated in the north of China and its popularity ranks first in all kinds of vegetables. So how do the scientific management of the bean pods?
What is the scientific management of bean pods?
1, adjust the plant
The beans need to be supported by brackets. This is a good agronomic skill for making good use of natural light to make nutrients and increase production value. When the pod climbs over the scaffold, it can be used to top the method to promote the germination and growth of collaterals. With regard to the use of nitrogen fertilizers by plants that are growing in prosperous areas, plant regulators such as chlormequat are sprayed. Remove the old leaves, diseased leaves or leaves from the lower part in time to ensure the ventilation and light transmission of the scaffold.
2, water and fertilizer management
The roots of the beans are weak, not tolerant to drought and not tolerant, and the soil should be kept dry to see moisture. The pod stage is also a period when the pod beans are very sensitive to water and fertilizer. If the supply of fertilizer and water is not sufficient, it is difficult to guarantee its output value and quality. To this end, when the pods are finished at the flowering stage, the management of water and fertilizer should be strengthened during the period of pod filling.
Based on sufficient base fertilizer, combined with watering, topdressing 15 kg of nitrogen and potassium fertilizer, or 10 kg of urea, 5 kg of potassium sulfate, and mix evenly. After entering the end of harvest, it will be topdressing for about 10 days. Sprinkle water mainly with small water, in the evening or early morning.
3, disease prevention and pest control
In production, the common diseases of common bean pods are mainly virus disease and rust disease. Continued high temperature and drought are often prone to viral diseases. Use 300 times the amount of virus A or 500 times of phytosanitary spirit spray to control. In the high temperature and humidity environment susceptible to rust, the use of triadimefon spray control. Common pests mainly include aphids, red spider mites, and soybean meal. Controlling aphids can use 10% imidacloprid, and 10 grams of water per acre can be used for water spray control.
The spider mites were used to control red spiders, and the main points were sprayed on the back of the blades. Use 1000-fold high efficacy cypermethrin to control soybean meal. Spray once every 7 to 10 days, 2 to 3 times in succession.
4. Spraying leaf fertilizer
Since June, the natural gas temperature in the outside world will tend to be over 30°C, and the sunlight will be sufficient. The high temperature and strong light will adversely affect the output value of the pods in the pod stage. In the production, it often appears that the phenomenon of falling flowers, premature aging and other attacks. After the application of foliar fertilizer can be useful to solve the onset of the above phenomenon, significantly increase the output value of beans. The use of boron fertilizer and potassium dihydrogen phosphate mixed evenly spray, 30 kg of liquid per acre of land, spraying once every 10 days.
5, timely harvest
Legumes generally reach harvest specifications about 10 days after flowering. The harvesting time is usually performed in the early morning or evening, when the temperature is low, do not touch the buds during picking, and sprain the bean shank so as not to affect the subsequent production value. About the picked whole bean squash, place it in a bamboo basket, cover the cotton quilt and keep it fresh, and promptly go to the farmers' market or bazaar for sale.
