Increase potato yield
Application of regulators to increase potato yield
Diethyl aminoethyl hexanoa (DA-6)
In the early flowering stage, foliar spraying of 60-100mg/L DA-6 liquid can significantly increase the net photosynthetic rate of leaves, increase the activity of SOD in leaves, reduce the content of MDA in plants, and make potato have a higher quality of life. Strong ability to scavenge active oxygen free radicals. At the same time, DA-6 can significantly increase the starch content in potato tubers, and to a certain extent, it can increase the content of vitamin C and protein, reduce the content of reducing sugar, and improve the quality of potato tubers.
Ascorbic Acid（Vitamin C）
Spraying 60 mg/L ascorbic acid solution at the potato seedling stage, tuber formation stage and tuber expansion stage can significantly reduce the occurrence of potato late blight and increase the tuber yield per unit area.
Choline chloride Foliar spraying at 300-400mg/L at the beginning of flowering, spraying once at 10-15d intervals, 2-3 times continuously, can increase the weight of each tuber and the average weight of tubers, and has a good effect of increasing yield.
Uniconazole
Under the condition of conventional planting density, spraying 40mg/L unconnoconazole on the tuber expansion stage can control the leggy length of the stem and promote the increase of yield.
Paclobutrazol When the plant height is 25-30cm, spraying the whole plant with 250-300mg/L paclobutrazol liquid can inhibit the leggy growth of stems and vines, promote the transfer of nutrients to the rhizome, promote the expansion of the rhizome and increase the yield.
Mepiquat chloride（PIX）
From the budding stage to the early flowering stage (the tuber rapid growth stage), spraying the leaves with 200m/l liquid medicine can increase the yield of "Kexin No. 13" by 10.77%. Spray once in areas with less rain, and spray once at intervals of 15-20 d in areas with good fertilizer and water, which can control the vigorous growth of plants, promote reproductive growth and increase yield.
Chlormequat(CCC)
From budding to flowering stage (rapid growth stage of tubers), spray with 1000-2000mg/L liquid medicine per mu. It is advisable that the leaves are all wet, which can delay the growth of stems and leaves, shorten the internodes, make the plants compact, and increase the chlorophyll content. , Change the distribution ratio of assimilation in the plant, the tuber formation time is 7d earlier, the growth rate is accelerated, the proportion of large tubers increases, the large tuber over 50g increases by 7%-10%, and the unit yield increases by 30%-50%. The appearance is as follows: The internodes are shortened, the plants are compact, the leaves are dark green, and the leaves become thicker.
