Application of regulators to improve the yield and quality of beetroot
DCPTA
Sugar beet is one of the main raw materials for the sugar industry, but with the extension of planting years, beet diseases and insect pests are becoming more and more serious, resulting in stagnant yields and a drop in sugar content. Spraying 30mg/L of increasing amine can increase the sugar increasing rate of sugar beet to 0.34°～0.94°, increase the yield by 9.2%～19.4%, and increase the sugar yield by 19.0%～29.4%.
Spermidine
Spraying 145mg/L spermidine in the rapid growth period of the leaves can increase the yield by 16.64% and the sugar yield by 19.84%.
Abscisic acid
Spraying 10mg/L abscisic acid in the rapid growth period of the leaves can promote the growth of tuberous roots, increase production and increase sugar.
Brassinolide
Spraying seedlings with 0.05mg/L brassinolide can reduce the content of malondialdehyde, relative conductivity and soluble sugar in leaves under low temperature conditions, and increase the chlorophyll content of beet, which is beneficial to improve its cold resistance; Two sprays of 0.1 mg/L brassinolide in the rapid growth period and in the root and sugar growth period had a significant increase in sugar production, which was 13.34% higher than that of the control.
Sodium Nitrophenolate
Spraying 12-16mg/L sodium nitrophenolate solution twice in the growing period can increase the plant weight, root weight and sugar content of sugar beet.
Triacontanol
0.5mg/L triacontanol soaked Shiding seedlings after foliar spraying before sealing ridges, the root yield, sugar content and sugar yield were improved more prominently, which were 14% higher than the control root yield, and 1.43% higher sugar content. °, the sugar production increased by 29%, the diseased plant rate was reduced by 8.58%, and the control effect was 20.9%.
Glyphosate
Spraying with 0.2%-0.3% liquid medicine in the late growth stage of sugar beet can inhibit the vegetative growth of the aerial part of the sugar beet, increase the sugar content by 0.6°-2.5°, and increase the sugar yield by 12.1%-17.7%, which has the effect of significantly increasing the sugar yield.
