Abstract

Combining different use modes and concentrations of PP₃₃₃,and taking ‘Chuanzao’ series precocious offsprings as test materials,three kinds of treatments were conducted on precocious walnut trees, including leaf spraying,infusion,and soil application. Analysis was made of influences of different application methods and different concentrations on walnut tree crown,twig length,leaf weight,fruit setting rate, fruit dropping rate and unit projected area yield. The aim was to screen the suitable application mode and concentration of PP₃₃₃,which could inhibit the walnut vegetative growth and increase the walnut production.
