| In order to solve the problems of excessive closed, fruiting capacity sharply droped and poor quality in
densely planting orchards, the pinching experiment was conducted by using main cultivars kenxianzao1 as materials in the
cold north xinjiang. The results showed that length of extension shoot(F=9.218) and length of secondary shoot(F=3.755) and
PnECInTCO2 shows very significant among various treatments.Difference of lipase length of bearing shoot (F=0.647)was
insignificant. Ticknessof extension shoot, length of internode etc were significant differences among various treatments.
Based on analysing on the topping characteristics of growth, development and photosynthetic characteristic parameters of
various treatments, we sums up optimization technical measures in the short-stalked and close-planting jujube yards, and
provide theoretical basis for tree size control of the short-stalked and close-planting jujube yards. |
