Abstract:
In order to provide a scientific basis for precocious walnut renewal,and explore the effect of the renewal of precocious walnut branches on the quality and yield of nuts,the nuts quality and yield of short-term renewal treatment (branch renewal cycle of 2—3 years) and conventional renewal treatment (branch renewal cycle of 3—4 years) trees were investigated with 6-year-old ‘Lyuling’ walnut tree as test material.The results showed that the three-diameters,single fruit weight and kernel yield of nuts with short-term renewal treatment were all higher than those of conventional renewal treatment,and the kernel yield difference was up to 2.45 percentage,showing a significant difference.The protein content of good fruit and light disease fruit with short-term renewal treatment were 20.64% and 19.73%,both significantly higher than those of conventional renewal treatment,and there was no significant difference in nucleolus fat content between the two treatments.The yield per plant of short-term renewal treatment was 2.54 kg,28% higher than that of conventional renewal treatment,and the proportion of good fruit yield was 69.18%,14.48% higher than that of conventional renewal treatment.Thus it could be seen that short-term renewal treatment can significantly improve the appearance quality and protein content of nuts,and it could significantly improve the nuts yield per plant,and extremely significantly increase the proportion of good fruit yield.
