"Twenty -four solar terms" is the wisdom of the ancient Chinese labor people, which has played a positive role in promoting agricultural development. Today is the third solar term in autumn, Bai Lu, which means that the weather has changed from heat to cool, and everything grows with the cold. Various autumn crops gradually mature and start harvesting one after another.

Professor Zhou Lin, deputy dean of the School of Botanical Protection, interviewed reporters from Dahe.com

If you ask who is the most star temperament in autumn harvest crops, it is a peanut known as "longevity fruit". At present, there are more than 20 million acres of peanut planting area in Henan Province, and the planting area and yield are ranked first in the country. It has played an important role in ensuring the supply capacity of edible vegetable oil in my country. At present, spring bioplasses and wheat ridge planting peanuts have entered a mature period of fruit, and they will start harvesting in about 10 days. On September 7, the reporter walked into Henan Agricultural University and invited Zhou Lin, deputy dean of the School of Botanical Protection to introduce the main points of peanut pest control before and after the majority of farmers' friends to help achieve high yield and harvest.

Three moves teach you to keep your harvest

"For summer sowing peanuts, the current period of podization to the maturity period of the pods is a critical period for output." Zhou Lin introduced that the focus at this time is to promote the expansion of the pods and the whole seed. , Increase the accumulation of dry substances and increase the oil output rate. At this time, the water consumption of peanut plants decreased sharply, the root system was weakened, and the disease resistance of the plant was reduced. Therefore, in terms of management technology, it is necessary to start with three aspects: fertilizer prevention premature aging, exclusive fruits, and disease prevention and leaves.

What is spray fertilizer to prevent premature aging? Zhang Lin said that although the peanut root absorption and fertilizer capacity weakened during this period, the demand for nutrients on the plant did not decrease. In order to prevent premature aging in the later period of peanuts, potassium dihydrogen phosphate, urea, and urea, urea, urea, urea, urea, urea, urea, urea, urea, urea, urea, and urea can be evenly sprayed. Calcium phosphate, iron sulfate, chelating iron, or peanut leaf fertilizer, etc., spray once every 7 to 10 days, spray 2 to 3 times in a row to promote the rich pods.

What should I do if the rain is too much at this time and the drainage is not well drained? Zhou Lin said that in order to prevent the rapid spread of leaf diseases such as brown spot disease and dark spots, we must pay attention to exclude water in time to prevent water flooding. But if you encounter drought, water it in time, don't hesitate.

Plants with brown spot disease

Zhou Lin told reporters that in the late period of peanut growth, the disease resistance of the plant was reduced, and it was very prone to cause of brown spot disease, dark spot, mesh, and scorched spot disease. The leaves fell into light before maturity, which seriously affected the expansion of the pods and caused the production to decrease. When the leather leaf rate in the field is 10%-20%, it is necessary to spray the drugs in time. You can choose benzene metharomodrazoline, phenyl metharopenazole, pyrazole ethane essence, , Pyramorrine, pyrazolehitiols, pyrazodol, fluoroplastazole, pyrazolehi, hydraol, pentaramine, polymorphin, methacoplasish Spray once every 5 to 7 days and spray 2 to 3 times.

Zhou Lin reminded friends of farmers to choose irrigation on the cloudy day when poured. On sunny days, she should avoid high temperature and strong light at noon, and choose to pour the irrigation before 10 am or after 5 pm. The purpose of the purpose can be used, such as spray irrigation, drip irrigation or ditch irrigation, and pouring irrigation methods to prohibit large water irrigation to avoid damaging fruit needles, root systems and young fruits; , Plant growth regulators such as water preservation agent, acetic acid, and mossidin, and other plants to improve the drought resistance ability of the plant, reduce the dispersal of water caused by the leaves of the leaves, promote the nutrition of stems and leaves to pods, and ensure the expansion of pods and normal maturity.

Nucleus

For peanut white silk disease, Zhou Lin reminded everyone to pay attention to it, it will form a lot of fungus, and it will be left into the soil to become the source of the first year or the next few years. In 5 years, chemical fungicides such as cypeopamide, 噻呋 噻呋 唑 唑, and other chemical sterilization agents can be treated in the roots of peanuts and the surrounding soil.
