Study on Increasing Yield of Qingxiang Walnut Ears

摘要:

该文通过对采穗圃各单株进行不同处理，探寻最佳的穗条增产措施组合，以期为核桃无性繁殖中充足的良种穗条提供科学依据。以两年生 “清香” 采穗单株为实验对象，通过留取 3,4,5 个一年生枝条，结合 3 月、6 月施肥与否然后通过适当的摘心，试验表明：留取 4 个一年生枝条的基础上仅在 3 月追肥 1 次，同时于 5 月底进行摘心处理，可获得最大的单株接穗产量 223.2 个芽。

Abstract:

This paper provides a scientific basis for the optimal combination of spikelets in the asexual reproduction of walnut through the different treatments of individual plants in the harvesting garden.The two-year-old" Qingxiang" harvested single plant as the experimental object, by taking 3,4,5 annual branches, combined with March, June fertilization or then through the appropriate topping, obtained:to take four annual branches on the basis of only 1 month in the top dressing, while at the end of May topping treatment, access to the largest single plant spike yield of 223.2 buds.
