施肥对软枣猕猴桃扦插育苗生长的影响
The Effect of Fertilization on the Growth of Actinidia arguta Cutting Seedlings
摘要
Abstract
This article adopts an orthogonal fertilization experiment with three factors(nitrogen,phosphorus,potassi-um)and three levels to study the effect of different nitrogen,phosphorus,and potassium fertilization ratios on the growth of A.arguta cutting seedlings,providing a basis for selecting a reasonable fertilization plan for cutting seed-lings.The results showed that the nitrogen phosphorus potassium ratio fertilization had a significant promoting effect on the rooting rate,root growth,and new branch growth of cuttings.There were significant differences in growth indicators such as rooting rate,root length,root thickness,root number,new branch length,new branch di-ameter,and bud number among different fertilization treatments.When the ratio of nitrogen,phosphorus,and potas-sium was 7 g/m of nitrogen,7 g/m of phosphorus,and 14 g/m of potassium,the rooting rate was the highest,reac-hing 78.91%;The root system had the best development,with a root length of 41.6 cm,a root thickness of 3.53 mm,and approximately 25 roots;The new branches grow vigorously,with a length of 77.40 cm,a thickness of 6.93 mm,and about 7 buds;The promotion effect on the cutting and seedling cultivation of A.arguta was the greatest,and it was the optimal fertilization treatment.关键词
