Research on Integrated Cultivation Practices for the Dedicated Special Small Potato Variety'Huashu 16'
摘要
Abstract
'Huashu 16',as a specialized variety for fresh consumption of small sized tubers,is characterized by high above-ground biomass,multiple main stems,and substantial yield of small sized tuber.The effects of key cultivation factors on the growth traits,yield,and tuber weight distribution of'Huashu 16'were systematically studied,including seed tuber size(5-80 g),and full growth period(70-141 days),planting density(4 500-9 000 plants/667m2),and plant growth regulators(chlormequat and uniconazole).Sprout length and diameter were found to be highly significantly affected by seed tuber size and sowing time,with sprout diameter being more strongly influenced by seed tuber size,whereas sprout length was predominantly determined by sowing time.Appropriate extension of the whole growth period promoted the yield increase.When the whole growth period exceeded 127 days,the proportion of tubers above 30 g showed an increasing trend.A planting density of 7 500 plants/667m2 was identified as a critical threshold,and exceeding this density led to decline in both emergence percentage and yield.Although uniconazole effectively controlled plant height and elevated the proportion of tubers within the 31-60 g range,the overall yield was significantly reduced.Considering the characteristics of the variety'Huashu 16',it is recommended to select seed tubers weighing 31-50 g,with a planting densities between 7 500 and 9 000 plants/667m2 and a full growth period of no less than 127 days in order to guarantee both the percentage of small sized tubers and overall yield.关键词
