Recently, some areas of our province have experienced continuous rainfall and even experienced heavy rainfall, and some fields have accumulated water. Although sweet potato has many advantages such as drought tolerance, thinness resistance, wide adaptability, etc., it is particularly resistant to cockroaches. The accumulation of water in the sweet potato field will cause the sweet potato to appear hard and the potato block rot. In order to reduce losses, the majority of farmers should be prepared for preventive and post-disaster remedies.
1. Discharge the water in the field in time. Due to excessive water accumulation or poor drainage after rain, the soil moisture is saturated, and the root system of sweet potato will cause disaster due to lack of oxygen. It is necessary to quickly construct a field drainage ditch, discharge water and reduce soil moisture in the field. Some heavily damaged fields cannot drain the water at one time, so that the sweet potato should be gradually adapted. Otherwise, the transpiration in the hot sun will lead to excessive water loss, which will easily cause the sweet potato to wither and lack water, which will aggravate the damage of sweet potato.
2. Cultivate weeding, loose soil and ridge. In order to improve the ventilation of the soil, timely cultivating and cultivating the ridges can also remove the weeds in the field. The artificial shallow hoe is combined with the mechanical squat when cultivating the loose soil. Artificial shallow hoes are used in the vicinity of potato seedlings, and the ridge slopes can be mechanically deep to 7 to 10 cm. This can not only protect the root system of sweet potato, but also promote the good ventilation of the roots, and also improve the soil temperature of the ridge body, which is conducive to long-winged potato.
3. Increase the application of quick-acting fertilizer. After the sweet potato is affected, the plant grows weakly and the soil fertility is lost. It can be combined with cultivating and timely application of quick-acting fertilizer, suitable for phosphorus, potassium and calcium fertilizer. On the one hand, it improves the good ventilation environment of potato roots and promotes new root regeneration. Restoring the normal absorption and transportation functions of plants, improving the metabolic mechanism and regulating the growth of plants; on the other hand, supplementing the soil due to leaching and causing the loss of certain mineral elements, prompting the sweet potato to resume growth as soon as possible.
4. Prevention of pests and diseases. When the sweet potato is flooded, the organ is damaged, the resistance is poor, and the environment with higher temperature and humidity is more susceptible to root rot, black spot, sweet potato stem nematode, etc., sweet potato moth, sweet potato hawk moth, Spodoptera litura, etc. Invasion of pests and diseases. Therefore, it is necessary to do a good job in measuring pests and diseases, reduce the damage of pests and diseases to sweet potato plants, and promote the healthy growth of plants.
