The key to high-yield control of summer sweet potato is to control the prosperity of the summer because of the recent rainfall.
If the growth is not controlled in time, the sweet potato seedlings will grow too vigorously and the sweet potato will not set.
It is too late to remedy the prosperous prostitution if it is not in time, and the prosperous drugs cannot be controlled.
Summer sweet potato control is generally carried out three times. The first control is carried out when the steering wheel of the sweet potato seedlings is large. The first time is light control, and the dosage should not be too large.
The prosperous control drugs generally choose multi-effect and ene-effect rubbing.
The second control of prosperity was performed 7 to 10 days apart, and the dosage was increased, and the third control of prosperity was carried out 7 to 10 days apart.
At this time, the amount of medicine is even more heavily controlled than the second time. Because of the frequent rains this year, it is recommended not to use swelling agents. Rainwater uses swelling agents because the sweet potato grows too fast and it is easy to crack and deform the fruit.
Second: To prevent waterlogging, it is necessary to drain water in time, and prepare for flood prevention, so that there is no accumulation of water in the ground after the rain.
