What issues should be noted when turning sweet potato vines?
1. When there is plenty of water, adventitious roots form at the stem nodes. These adventitious roots can absorb a large amount of nutrients and water, making vegetative growth vigorous and causing the vines to grow excessively, while inhibiting reproductive growth, so the tubers grow slowly. At the same time, the adventitious roots also produce small tubers, causing insufficient nutrients and creating a situation where "everyone goes hungry," which...

What issues should be noted when topdressing eggplants in summer?
1. Appropriate amount. Eggplants have the highest demand for nitrogen fertilizer, but in high-temperature seasons, each application of urea per mu should generally be controlled within 30 kg, because in high-temperature seasons, urea transforms relatively quickly after being applied to the soil, and after the plants have met their needs, the excess portion will be lost. Especially in sandy soil, the proportion lost will be even greater...

What issues should be paid attention to in the management of single-season rice and other field crops
In the past week, the weather has continued to be hot with strong sunlight, field evaporation has been very high, and some rainfed fields have already experienced water shortage and drought. In the management of single-season rice and other field crops, attention should be paid to the following issues: 1. Spraying for disease and pest control should be done in the morning and evening, and sufficient water should be used. At present, it is the suitable period for controlling the fourth (2) generation leaf roller and rice planthopper of single-season rice. When selecting appropriate pesticides for control, the spraying time should preferably be before 8 a.m. or after 5 p.m., avoiding the high-temperature and strong-sunlight period as much as possible, and sufficient water should be used

What issues should be noted when harvesting sweet potatoes?
Sweet potato is a vegetatively propagated vegetative body, with no obvious maturity standard or harvest period, but harvesting too early or too late affects the yield, seed retention, storage, processing and utilization, and crop rotation of sweet potatoes. Harvesting too early will significantly reduce the yield of sweet potatoes; harvesting too late, sweet potatoes are often affected by low-temperature chilling injury, are not resistant to storage, and the drying rate declines. Therefore, sweet potatoes must be harvested at the right time. The suitable harvest period for sweet potatoes should be determined according to climatic conditions, safe storage time, and the arrangement of the following crop. When the ground temperature is around 18°C, the weight increase of sweet potatoes is very small; when the ground temperature is
