Properly controlling excessive vine growth in sweet potatoes can promote high yields
Sweet potato is a crop with high and stable yields. It has the characteristics of wide adaptability, strong stress resistance, drought and barren tolerance, and relatively few pests and diseases. When planted in places with good water and fertilizer conditions, it can generally yield 2000--3000 kg per mu. However, due to differences in natural conditions and cultivation levels, the yield per unit area is also extremely uneven. In order to fully...
To control excessive vine growth in sweet potatoes and increase their yield, the main specific methods are: promptly pinch the tops of the sweet potatoes, picking off the tender tips on the sweet potato vines, preferably about 3 cm in length, generally pinching the tops once every 15 days, and doing it 2 to 3 times. If there is heavy rain, lift the potato vines after the rain, then put them back in place, lifting the vines without turning them. If the sweet potato vines are found to be growing excessively, chemical control should be taken promptly, using 75 g of paclobutrazol per mu, mixed with 50 kg of water for foliar spraying, spraying once every 7 to 10 days, and spraying 2 times in succession.
