- Abstract:
- Using 7-year-old ‘YanFu 3 apple/M26/Malus hupenensis’ as test material, humic acid fertilizers (CK,conventional fertilization;FA1,fertilizer reduce 20%+humic acid fertilizers in conventional fertilizers;FA2,fertilizer reduction 10%+humic acid fertilizers in conventional fertilizers) were set,the effect of reducing fertilizer investment and increasing efficiency on apple was studied.The results showed that compared with CK,the leaf area,chlorophyll content,100 leaf weight and the length of the bourse shoot of FA1 were increased by 7.46%,3.59%,9.49% and 6.22% respectively.Single fruit weight,total soluble solid,fruit transverse diameter,fruit longitudinal diameter,fruit hardness increased 9.57%,8.56%,5.84%,6.79%,17.31%.Total titratable acidity reduced 5.00%,yield and fertilizer partial productivity increased by 9.97%,12.45% respectively.Compared with the CK treatment,application of FA2 decreased the leaf area,chlorophyll content,100-leaf weight index by 11.05%,8.11%,16.80% and 17.62% respectively,single fruit weight,soluble solid,fruit transverse diameter,fruit longitudinal diameter,fruit hardness increased by 19.72%,10.60%,9.23%,11.81%,23.08%respectively.Total titration acid reduced by 7.50%,yield and fertilizer partial productivity increased by 18.21%,31.20% respectively.The comprehensive analysis suggested that humic acid fertilizer could promote the growth of leaf and fruit stand,improve the fruit quality and improve the yield.The effect of conventional fertilization with reduced by 10% plus humic acid fertilizers treatment was the best compared with the conventional fertilization.
