The occurrence of peanut pod damage is due to low-lying terrain, heavy clay soil, and poor drainage. Second, there is an excess of surface water and groundwater during periods of long rainfall or excessive rainfall. Peanuts are afraid of drought, and rain has a great influence on the growth and development of peanuts. After the peanut has suffered a locust plague, it is necessary to take timely measures to strengthen field management in order to reduce disasters and ensure production. The specific approach is:
Exclude water in the field in time According to the situation of water accumulation and the topography, drainage machinery and digging drainage ditch are adopted to expel the stagnant water in the field and stagnant water as soon as possible to minimize the time of field water accumulation.
Membrane spasm to reduce rotten fruit soil water content is too high, should be timely film rupture, to maintain good ventilation of the soil to reduce the occurrence of rotten fruit.
Timely application of quick-impact peanuts after flooding, soil nutrient loss, coupled with weak root absorption capacity, timely dressing is very beneficial to restore plant growth and increase yield. Before the plants resumed growth, they were sprayed 2-3 times with the fungicide hellazole+0.2%-0.3% potassium dihydroborate solution +0.5%-1% urea solution to reduce the damage.
After the prevention and control of pests and diseases, high temperature and high humidity in the field, coupled with weak growth of peanuts and reduced resistance, are suitable for the occurrence of various pests and diseases. Investigation and control must be conducted in time to control the spread. The main prevention and treatment of peanut leaf spot, cotton bollworm and other pests and diseases.
The working process of the washing machine consists of four processes: water inlet, laundry, drainage, and dehydration. In a semi-automatic washing machine, these four processes are controlled with corresponding push-button switches. In a fully automatic washing machine, these four processes can be automatically run in sequence until the end of the laundry. Industrial washing machine features
