Inhibit excessive growth of sweet potato vines and increase yield
Application of growth regulators to inhibit excessive vine growth in sweet potatoes and increase yield
Prohexadione calcium
Spraying 200-300 mg/L prohexadione calcium solution at the early flowering stage can significantly inhibit the vigorous growth of potato mango, promote the transfer of nutrients to the underground part, promote the expansion of potato pieces, and increase the yield.According to the test, the overall chlorophyll content showed a trend of increasing first and then decreasing, because the growth had been mainly transferred from the vegetative growth on the ground to the underground part.Prohexadione calcium treatment can effectively maintain the chlorophyll level of sweet potato plants, promote the accumulation of dry matter and the proportion of the underground part in the distribution of plant assimilation, which is beneficial to the accumulation and expansion of dry matter of roots, and the yield can be increased by 30%.
Choline chloride
Foliar spraying with 400-800 mg/L liquid medicine at the beginning of tuberous root and tuber formation or expansion, spraying once every 10-15 d, and continuous application 2-3 times can promote yield increase. The effect of compound naphthalene acetic acid is more significant.
Chlorhexidine
30 d after planting, 2500 mg/L of medicinal liquid per mu can be used for foliar spraying, which can control the leggy growth of potato vines and increase yield by 15% to 30%.
Formaline
When the vine grows to 0.8~1m (rapid tuber growth period), spray the whole plant with 200~-300 mg/L liquid medicine 1~2 times, and spray once in areas with little rain, and the fields with good fertilizer and water can be sprayed 15 times ~20 d and then spray 1 time.It can inhibit vegetative growth, control vine growth, prevent nutrient loss, and promote rhizome expansion. The yield of fresh potato increased by 5.39%~11.82%. The yield of dried potato increased by 10.08%~20.75%.
Paclobutrazol
Spraying 150-300 mg/L paclobutrazol solution on the leaves at the branching and tuber stage, with a liquid volume of 225 L/hm2, can significantly increase the chlorophyll content of leaves, the yield of tubers and the content of starch and protein, and reduce the disintegration of starch. It can significantly increase the glucose content of tubers, reduce the sucrose content of tubers and the minimum starch viscosity value, and can reduce the maximum vine growth of 24.09% sweet potato, promote the formation of potato pieces, and have obvious effects of increasing yield and quality.
Uniconazole
Spraying with 30-50 mg/L liquid medicine at the initial stage of potato block expansion can control vegetative growth, promote underground potato block expansion, and increase yield.
Ethephon
Foliar spraying of ethephon can inhibit the growth of sweet potato vines, significantly increase the chlorophyll content of leaves, root tuber yield, starch and protein content, reduce the disintegration value of its starch, significantly increase the sucrose content of tuberous roots, and reduce its maximum starch viscosity value.During the ridge sealing period, 2000 mg/L ethephon was sprayed on the leaves and the liquid volume was 225 L/hm 2, which could reduce the maximum vine length of sweet potato by 37.33%.
